Location X - Latitude User-defined GPS latitude coordinates of the node that is displayed on Digi Remote Manager and Network Assistant. text 15 1 ASCII Location Y - Longitude User-defined GPS longitude coordinates of the node that is displayed on Digi Remote Manager and Network Assistant. text 15 1 ASCII Location Z - Elevation User-defined GPS elevation of the node that is displayed on Digi Remote Manager and Network Assistant. text 15 1 ASCII Access diagnostic parameters Firmware Version Read modem firmware version number. 0x none Bootloader Version Display the Bootloader version 0x none Hardware Version Read modem hardware version number. 0x none Hardware/Firmware Compatibility Specifies what firmware is compatible with this radio. Firmware with a compatibility value lower than the value returned by %C cannot be loaded onto the board. 0x none Supply Voltage Read the supply voltage of the module in mV units. 0x none MAC ACK Failure Count The number of unicast transmissions that timed out awaiting a MAC ACK. 0x0 number 0xFFFF 0x0 Temperature Read power compensation temperature sensor in units of Celsius degrees. 0x none Configuration Checksum The CRC of the current settings. The purpose of this command is to allow the detection of an unexpected configuration change on a device. After a firmware update this command may return a different value. 0x none
