HAMPod PM2 MeterReader for the Array Solutions Power Master 2
Revised 06/25/2015
Firmware: v1.04

OVERVIEW
  The HamPod series of Amateur Radio station accessories are stand-alone, micro-processor based text-to-speech devices designed to provide speech output and accessibility to common station equipment such as transceivers, antenna controllers and rotor controllers, SWR/Power meters and other equipment capable of serial data exchange. The voice synthesizer utilizes the popular "Double Talk" voice synthesizer and is customizable to your personal preferences.

  The HamPod PM2 MeterReader has been specifically designed to work with the Array Solutions Power Master 2 SWR/Power meter to provide as much capability and accessibility to the meter as possible. With the PM2 MeterReader you will have access to the configuration parameters of the Power Master 2 and be able to read the SWR and power data and use your Power Master 2 meter with enhanced functionality providing a high degree of capability. All without the need for a connected station computer or help from a fellow ham or long-suffering partner!
       
  There are several options that determine how the HamPod PM2 MeterReader performs and interacts with your Power Master 2 meter and all options are stored in EEPROM within the HamPod and retain their settings when powered off. The 16 button keypad is used to configure the HamPod and for accessing the Power Master 2 meter.  Many of these keys also perform queries to retrieve information from the Power Master 2 meter when desired with your choice of either a verbose or less chatty terse mode.


GENERAL DESCRIPTION
  The rear of the HamPod Power Master 2 MeterReader has two male DB9 serial ports and a DC power jack. The serial ports are identified as serial port 1 and serial port 2. The connector located next to the power jack is port 1. Depending on the firmware loaded in your HamPod, you can possibly connect a PM2 on each port, or  connect the PM2 on port 2 and another device on port 1. Serial port 1 is also used to connect to a computer serial port using a null modem cable to flash the firmware in the HamPod when an upgrade is available. See Appendix C for upgrade instructions. The power jack accepts 9 to 12 volts dc and has a positive center pin.  There is also a small hole at the lower left corner of the speaker grill which provides access to a reset button inside the enclosure.  This hole is located within the very bottom groove of the speaker grill and about one quarter of an inch from the left end of the groove. You can use a paper clip to reach into the box to push this button. The button is about one inch below the top cover. Be careful not to poke through the speaker cone if you happen to be somewhere above the very bottom  groove of the speaker grill area. This button will reboot the HamPod without changing any configuration settings.


CONNECTING THE HamPod PM2 MeterReader
IMPORTANT! If the USB cable is currently plugged into your Power Master 2 meter, you must remove it for the meter to send data through the serial port.
CAUTION! Do not apply power to the HamPod until you have connected it to your Power Master 2 meter . This is because the serial port jacks on the rear of the HamPod are male connectors and it is possible to short one of these pins to the grounded shell while trying to engage the female end of the serial cable into this connector.
1.    Connect the male end of the serial cable to the RS-232 DB-9 serial port on the rear of the Power Master 2.
2.  Connect the female DB-9 on the other end of the cable to Port 1 on the rear of the HamPod unless your HamPod has firmware to allow multiple types of devices in which case the PM2 is usually connected to port 2.
3. Connect power to your Power Master 2 meter.
4.  Connect the supplied 9 volt DC, 800MA wall power unit to the HamPod . This is a center pin positive 2.1mm x 5.5mm coaxial power connector. You may also connect this using your own cable to your shack 12 volt DC power distribution system if desired. There is no on/off switch on the HamPod as it draws minimal current when not in use.
5. Be sure to select the correct Port you  have connected your PM2 on the HamPod by pressing and holding the [D] key on the HamPod.
  The HamPod PM2 MeterReader communicates with the Power Master 2 meter at a baud rate of 38,400. When powered up, the PM2 MeterReader will announce "Ham Pod" followed by "PM2" if the Power Master 2 is correctly connected and is communicating with the HamPod.


KEYPAD
  The layout  of the first 12 keys of the 16 button keypad is similar to a standard 12 key telephone keypad with an additional column of 4 keys to the right.  The 16 push buttons keys are arranged as 4 rows of 4 columns and each key is capable of two different functions depending on the current mode of the Power Master 2 MeterReader. They are operated with both a standard push or an extended longer push and hold action. With the addition of a "Shift" key, each key can generate up to four unique operations. A synopsis of the switches and their functions are listed in Appendix A for reference. As previously mentioned, the first three columns of keys are labeled identically to a standard 12 key telephone keypad. The fourth column of keys are primarily configuration and modifier keys.

  In this document, the key labels are enclosed within square brackets. For reference, left to right, top to bottom, the keys are labeled:

Row 1: [1], [2], [3], [A]
Row 2: [4], [5], [6], [B]
Row 3: [7[, [8], [9], [C]
Row 4: [*], [0], [#], [D]

  The keys are always pushed individually. Never is more than one key pressed at a time to perform any function.

  There are two modes of operation for the keypad and are as follows:
1. Normal Mode. Standard user operation.
2. Configuration Mode. This allows setup of DoubleTalk voice parameters as well as HamPod PM2 MeterReader options.


1.  NORMAL MODE  - Features and Operation
  The Array Solutions Power Master 2 SWR/RF Power meter was found to be an accurate meter with some nice features such as its depth of options, coupler calibration,and of course, the inclusion of its serial port. The HamPod PM2 MeterReader is able to provide almost total access to the Power Master 2 and even better, when accessing the menus and setup options on the Power Master 2, it allows you to use the meter as a sighted user by the use of the two front panel buttons on the meter itself and the HamPod will enunciate the LCD display text automatically. This is also true when selecting the different LCD display modes using the Power Master 2's "Select" button. So when you need to make a change to your meter's settings, you operate the Power Master 2 as directed in the owners manual and the HamPod will read the LCD display automatically to you as you scroll through the options and settings using the two push buttons on the meter. This also means there are only a handful of keys to memorize on the HamPod for use with the Power Master 2. These keys perform things like reading the power, SWR, resetting any alarms, and choosing couplers. See the key assignment list below for all HamPod key functions for use with the Power Master 2.


using the HamPod with your Power Master 2.

When a key is pressed for either a power or SWR reading, the HamPod will  look for the presence of RF power and if detected, will perform the request and report the results. If no RF power is detected, the HamPod will emit an ascending two tone beep and will wait for 5 seconds for you to initiate a carrier. When RF is detected, a short beep will sound letting you know the HamPod  has detected the RF and will wait for an additional second for the power to stabilize and will then report the reading. The process will automatically abort after 5 seconds if no RF is detected signified by a descending two tone beep. This way, you can "arm" the HamPod with a key press, then move to your radio to perform the transmission to be measured.

You can conveniently get a combined reading of all three values (forward, reflected, SWR) and the status of any alarms if they have been tripped by a single press of the [5] key. If no power is detected and all values return as zero, the HamPod will just report a single zero.

We have also attempted to add an audio tone tuning feature to the PM2 MeterReader. When this function is selected, the HamPod will continuously query the Power Master 2 meter and convert the reading to a tone that will increase in pitch as the power or SWR increases. This allows the tuning of an amplifier for maximum output or adjusting an antenna tuner for lowest SWR. Currently, there are two modes of audio tone generation within the HamPod. The first is a tone generator created within the HamPod's microprocessor and results in a continuous audio tone. The second method is a pulsing tone that is generated by the text-to-speech synthesizer hardware. There is an inherent problems with trying to generate a responsive audio tone derived from a serial data stream. First is the issue of the time it takes for the device to measure, calculate, format and finally send the data over the serial port at the chosen baud rate. The Power Master 2 does a good job of performing this in a reasonable amount of time. Second is the time required for the receiving device to read, process, and use the data to generate and appropriate audio tone. Both of these times are additive and are referred to as latency and is noticeable by the time it takes for the HamPod to react to a change detected by the meter. The continuous tone generations is the most responsive and is therefore the preferred method as it results in less latency and the quickest response to the changing serial data. The second method using the pulsing audio tone derived from the text-to-speech synthesizer suffers from additional latency while generating its tone because the hardware was not designed for this specific capability. To help mitigate these issues, we allow some parameters to be adjusted within the configuration menu of the HamPod that can be optimized for your particular situation. There are two settings in the configuration menu which control how the pulsing audio tone tuning  mode behaves. These are: Pulse Rate, and Pulse Width. Please note that these only effect the pulse tone tuning mode and due to the design of the text-to-speech audio generator within the HamPod, the audio tone must be created using a pulsing tone. Therefore, the Pulse Rate option set the speed at which the Power Master 2 meter is queried for data and The Pulse Width sets the duration of each audio tone per pulse. Unfortunately, with the combination of latency involved with reading data via a serial data connection and the issues with tone generation, these are not the most ideal conditions for this function. But by choosing the best tone generation method and under the   right circumstances and settings, it might be a workable, although a bit sluggish, solution.  There are also configuration options that allow the audio tone to auto scale over the full range of data as it is received or you can select a fixed range.

To enter the audio tuning mode, perform either a long press of the number 1, 2, or 3 keys for the continuous tone tuning, or a [Shift], long press of the number 1,2,or 3 keys for the pulse tone tuning depending on the parameter you want to monitor. The HamPod will remain in this mode until any key is pressed to exit. If the [*] key is pressed to exit, the final value received will be announced. This feature is nice because you can be tuning your amplifier for maximum power with the tone and if you exit the tuning mode with the [*] key you will hear the final power value announced, provided of course RF power is still applied to the meter when you exit. That way, you don't have to take an additional reading to see what the final output power was.


  Listed below are  the assigned functions for each key. Note that for clarity, in normal mode, the [A] key (upper right corner key) is also referred to as the [Shift] key.
Most keys have two potential functions by either simply pressing the key, or pressing and continue holding the key down for an additional .5 second. And that combined with the [Shift] key, we can then get up to four unique functions for each key.

In normal mode, the keys have been assigned the following functions:

2.  CONFIGURATION MODE
  This mode allows changes to the various voice settings as well as modifying the options which effect how the  HamPod PM2 MeterReader interacts with your Power Master 2 meter. To enter Configuration Mode, press and hold the [C] key for 1 second. When you enter the configuration menu, you are placed at the option you last viewed when you previously exited the configuration menu.

In Configuration Mode the keypad switches perform the following functions:
[A]: Step forward through the configuration options.
[B]: Step backward through the configuration options.
[C]: Increment the parameter values.
[D]: Decrement the parameter values.
These are circular menus and will cycle through once  the first or last choice has been passed.

To exit and save your changes, press and hole the [C] key for 1 second. The settings are stored in EEPROM and will remain even when power is removed.

To exit without saving your changes, press and hold the [D] key for 1 second. Any changes you may have made will not be stored in EEPROM but those changes will still remain in effect until you power off or reset the HamPod PM2 MeterReader. If the key timeout function is active and you don't press a key before the timeout occurs, you will also exit the configuration mode without saving to EEPROM.


HamPod PM2 MeterReader CONFIGURATION OPTIONS
1. Key beep: on/disable. This sounds a beep when a key is pressed.

2. Key Time out Duration: Disable / 5-30 Seconds You can either disable this option or set the time out duration from 5 to 30 seconds. When set to a value, this sets the length of time for the key time out period.  If an action to be performed requires multiple key presses and you fail to fully input the sequence, a time out will occur after the set time duration and the HamPod will abort the current partial keypad entry.

3. Verbosity: on/disable. When enabled, some responses from the Power Master 2 meter will announce additional information such as labels and prompts along with the data returned from the meter.

4. Pulse Rate: 0 - 20. When using the audio pulse tuning tone functions, this sets the rate at which the Power Master 2 meter is queried for data. A setting of 0 is fastest and 20 is slowest.

5. Pulse Width: 2 - 9. When using the audio pulse tuning tone functions, this sets the length of the tone pulse. A setting of 2 is shorter and 9 is longer.

6. Power On To Port:  1/2 Selects which serial port is active when the HamPod Power Master 2 MeterReader is powered on.

7. Reset Now?: Used to reset the HamPod Power Master 2 MeterReader. When at this option, you can press either the [C] or [D] keys to alternate between enabling or disabling the opportunity to reset. When the Power Master 2 MeterReader informs you to "Enter to Reset", you can then press the [Enter] key to initiate the reset. If you do choose to reset, the Power Master 2 MeterReader will perform a 3 second countdown before performing the reset process. This is useful when you want to coordinate the reset with the application running on your PC for the purpose of updating the firmware. This reset only occurs on the HamPod and not the Power Master 2 meter.

HamPod DoubleTalk VOICE PARAMETERS

APPENDIX C

FIRMWARE UPGRADE OVERVIEW
The procedure to flash the firmware is standard practice as with other devices that utilize a bootloader. There are basically two components used for this procedure:
1.  The bootloader which is already resident within your HamPod.
2.  A Windows based computer running an application that communicates with the bootloader and sends the new firmware to the HamPod.

The bootloader is a special application that resides within the HamPod and runs every time the device is either reset or  powered on. This special application looks for a unique command sequence over serial port 1 of the HamPod which is connected to your computer which is running the companion Windows flash loader  application. Once the bootloader begins, you have approximately 1.5 seconds to initiate the flash loader application running on the computer. During that first 1.5 second window of opportunity,the bootloader is in control of the HamPod and is looking for a connection from the computer over the serial port. When a valid connection is established between the HamPod and the application running on the computer, the flash loader application then sends the new firmware to the HamPod. If no connection can be established, the bootloader times out and the HamPod starts running as usual.


FIRMWARE UPDATE PROCEDURE
1.  Important! You must use a null modem serial cable for this connection. Connect a null modem serial cable between serial port 1 of the HamPod (the connector nearest the DC Power jack), and a serial comm port on your personal computer. The comm port on your computer can be any serial port from COM1: to COM8:. The existing straight wired serial cable provided with your HamPod can be used provided you also use the included null modem adapter in addition to this cable.
 2.  Download and extract the ZIP archive update  firmware file to any directory of your choosing on your computer. You may over write any existing files with a new firmware update if you have previously performed this update before. This file can be found from the Power Master 2 MeterReader page on the HamPod web site at the following URL:
http://www.HAMPod.com

The files contained within the ZIP archive are:
ds30LoaderConsole.exe : The command line flash loader application.
Flash_1.bat : Batch file when using comm port 1 on PC.
Flash_2.bat : Batch file when using comm port 2 on PC.
Flash_3.bat : Batch file when using comm port 3 on PC.
Flash_4.bat : Batch file when using comm port 4 on PC.
Flash_5.bat : Batch file when using comm port 5 on PC.
Flash_6.bat : Batch file when using comm port 6 on PC.
Flash_7.bat : Batch file when using comm port 7 on PC.
Flash_8.bat : Batch file when using comm port 8 on PC.
Power Master 2.hex : the firmware file to flash to the Power Master 2 MeterReader

3.  Once you extract the files into a directory of your choosing, simply run the appropriate batch file for the comm port number on your PC that you have connected to the HamPod.  The batch file contains the command to launch the flash loader  application and also set some necessary parameters for the program. When you start the batch file, the file will open a DOS window, validate the new hex firmware file, and prepare to flash the HamPod but will stop and wait for any key to be pressed on the PC before actually initiating the flashing process. The text written into this DOS window by the flashing application should be readable by most screen readers such as JAWS or Window EYES and will inform you of its progress.

4.  Once the application pauses and is waiting for a key press, you must reset or power on the HamPod but remember, once you initiate the reset, you only have 1.5 seconds to press any key on the PC to start the loading process before the bootloader within the HamPod times out while waiting for the PC connection. If the bootloader fails to connect to the PC, it automatically starts the Power Master 2 MeterReader application and you will need to start over.

There are five ways to reset the HamPod Power Master 2 MeterReader:
A.  Remove power from the HamPod for a couple seconds then restore the power.
B.  Use a paper clip to push the reset button within the HamPod located at the lower left corner of the speaker grill.
C.  Locate and perform the "Reset Now?" option withing the Configuration Menu of the HamPod.
D.  Press the [SHIFT] key followed by a long press of the [#] key to restore factory defaults. This will ultimately cause a reset after restoring those default values.
E.  Press the [SHIFT] key followed by a long press of the [0] key to cause a three second countdown and a reset.

5.  Once the reset has been initiated, you have about 1.5 seconds to start the flash procedure on the PC by pressing any key such as the Space Bar. When a key is pressed on the PC, the flash loader application will try to establish a connection with the bootloader within the HamPod and if found, will continue with the update. This will take about 30 seconds to complete. DO NOT power off the HamPod while the update is in progress!When finish, the HamPod may restart on its own but sometimes you may need to power cycle the HamPod yourself. The flash loader application on the PC will write a series of period characters to the screen as it transfers the firmware file to the Power Master 2 MeterReader, When finished, it will report the status of the update and wait for a final key press on the PC to terminate the flash application and close the DOS window.

If you failed to start the PC application on time or the process is unsuccessful, You can repeat this procedure until you get the timing sequence correct.

6.  After a successful update, you can verify the new firmware has been installed by requesting the product information from the Power Master 2 MeterReader by entering the keypad query on the HamPod Power Master 2 MeterReader as previously described in the key assignment section of this manual to report the current firmware version.
7.  Disconnect from the PC and reconnect the HamPod to your Power Master 2 meter and enjoy the new benefits and features of the firmware!

73 and Have fun with your HAMPod PM2 MeterReader!
