<\/p>\n

\n

Upgrading to version B10 Firmware<\/em><\/em><\/span><\/span><\/h1>\n<\/div>\n

Version B10 introduced a number of new features and parameters in the M7 radio. <\/span>Because these new features have parameters stored in EEPROM, the new features must be manually initialized on radios that have a previous version of the firmware. <\/span>Any radio with a current firmware version less than B10, must <\/span>have the following commands executed. <\/span>If the firmware in the radio is already B10 or higher, you will not need to do the following commands.<\/p>\n

Once the version B10 (or higher) firmware has been loaded into the radio, execute the following commands:<\/p>\n

Set the radio back to factory defaults<\/h2>\n

AT&F <\/strong><enter><\/span><\/em><\/p>\n

Set the group code to 0<\/h2>\n

ATGP 0 <\/strong><enter><\/span><\/em><\/p>\n

Set the charge pump current<\/h2>\n

CPUMP 13<\/strong><enter><\/span><\/em><\/p>\n

Set the channel frequency<\/h2>\n

ATFX xxx.xxxx<\/strong><enter> <\/span>All previously stored frequencies were probably erased with B10<\/span><\/em><\/p>\n

Recalibrate RSSI<\/h2>\n

AT$A 340<\/strong><enter> <\/span>The A\/D reading at -100dBm<\/span><\/em><\/p>\n

AT$B 530<\/strong><enter> <\/span>The A\/D reading at -70dBm<\/span><\/em><\/p>\n

If the radio is a \u2013GX version (GPS )<\/h2>\n

GPS&F<\/strong><enter><\/span><\/em> <\/strong><\/p>\n

GPS X <\/strong><enter> <\/span>where X is the desired GPS mode of operation<\/span><\/em><\/p>\n

SLOTQTY 1<\/strong><enter> <\/span>Set the number of tdma slots to 1 .<\/span><\/em><\/p>\n

Re-calibrate RF power output calibration<\/h2>\n

AT$P xx <\/strong><enter> <\/span>adjust <\/span>XX value so that the RF power output is correct. Use a wattmeter connected to the M7 to read the power. <\/span>Monitor the current craw, and ensure it does not exceed 2.8A. <\/span><\/em><\/p>\n

AT$R -10 <\/strong> <\/span>PA temperature compensation.<\/span><\/em><\/p>\n

\n

\n

Upgrading to Version B24 Firmware<\/em><\/em><\/span><\/span><\/h1>\n<\/div>\n

Since B10, a number of new features and parameters in the M7 radio. <\/span>Because these new features have parameters stored in EEPROM, the new features need to be initialized before the radio will work. <\/span>Normally, this is done at the factory, but it you are upgrading the firmware in the field, you should execute the following commands after you have uploaded B24 into your radio. <\/span><\/p>\n

Your MUST execute the following commands, based upon the firmware version you were upgrading from. <\/span><\/p>\n

FREEWHEEL 120 <\/span> <\/span><\/strong>(Only if your radio has a GPS and is a \u2013GX version)<\/p>\n

TDMADATA 0 <\/span> <\/span><\/strong>(Only if your radio has a GPS and is a \u2013GX version)<\/p>\n

SLOTNUM -1 <\/span> <\/span><\/strong>(Only if your radio has a GPS and is a \u2013GX version)<\/p>\n

ATJF 3000 <\/strong>Set the hardware flow control threshold.<\/p>\n

\n

\n

Upgrading to Version C2 Firmware<\/em><\/em><\/span><\/span><\/h1>\n<\/div>\n

Since B24, a number of new features and parameters in the M7 radio. <\/span>Because these new features have parameters stored in EEPROM, the new features need to be initialized before the radio will work. <\/span>Normally, this is done at the factory, but it you are upgrading the firmware in the field, you should execute the following commands after you have uploaded C2 into your radio. <\/span><\/p>\n

Your MUST execute the following commands, based upon the firmware version you were upgrading from. <\/span><\/p>\n

BANDL xxx <\/span><\/strong>Set the lower end of the band, in MHz. For example if your radio is a 450-470Mhz radio, the BANDL must be <\/span><\/span>BANDL 450.<\/strong><\/p>\n

BANDH xxx <\/strong> <\/span> <\/span>Set the uppder end of the radio band, in MHz. <\/span><\/span><\/p>\n

PASSWORD 0 <\/span> <\/span><\/strong>Disables the user password feature introduced in version C of the firmware.<\/p>\n

CPUMPL 0 <\/span><\/strong> <\/span>Charge pump compensation at low end of the band. <\/span><\/p>\n

CPUMPH 0 <\/span><\/strong> <\/span>Charge pump compensation at the high end of the band.<\/span><\/p>\n

<\/p>\n

ATCD -113<\/strong> <\/span>Set the carrier detect threshold to -113dBm. <\/span><\/p>\n

<\/span><\/p>\n

\n

Re-calibrate RF power output calibration<\/span><\/span><\/em><\/h2>\n

AT$P xx <\/span><\/strong><enter> <\/span>adjust <\/span>XX value so that the RF power output is correct. Use a wattmeter connected to the M7 to read the power. <\/span>Monitor the current craw, and ensure it does not exceed 2.8A. <\/span><\/em><\/span><\/p>\n
