When output is set, due to I/O line passing, to a non-default level a timer is started which when expired will set the output to it default level. The timer is reset when a valid I/O packet is received. If set to 0, there is no timeout. 0x0 number 0xFF 0x0 x 100 ms D8 Output Timeout Set/Read Output timeout value. When output is set, due to I/O line passing, to a non-default level a timer is started which when expired will set the output to it default level. The timer is reset when a valid I/O packet is received. If set to 0, there is no timeout. 0x0 number 0xFF 0x0 x 100 ms D9 Output Timeout Set/Read Output timeout value. When output is set, due to I/O line passing, to a non-default level a timer is started which when expired will set the output to it default level. The timer is reset when a valid I/O packet is received. If set to 0, there is no timeout. 0x0 number 0xFF 0x0 x 100 ms P0 Output Timeout Set/Read Output timeout value. When output is set, due to I/O line passing, to a non-default level a timer is started which when expired will set the output to it default level. The timer is reset when a valid I/O packet is received. If set to 0, there is no timeout. 0x0 number 0xFF 0x0 x 100 ms P1 Output Timeout Set/Read Output timeout value. When output is set, due to I/O line passing, to a non-default level a timer is started which when expired will set the output to it default level. The timer is reset when a valid I/O packet is received. If set to 0, there is no timeout. 0x0 number 0xFF 0x0 x 100 ms P2 Output Timeout Set/Read Output timeout value. When output is set, due to I/O line passing, to a non-default level a timer is started which when expired will set the output to it default level. The timer is reset when a valid I/O packet is received. If set to 0, there is no timeout. 0x0 number 0xFF 0x0 x 100 ms PWM Output Timeout Specifies how long both PWM outputs (P0, P1) output a given PWM signal before it reverts to the configured value (M0/M1). If set to 0, there is no timeout. This timeout only affects these pins when they are configured as PWM output. 0xFF number 0xFF 0x0 x 100 ms User-defined parameters used to store the physical location of the deployed device. 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 Information about the XBee hardware and firmware 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 Power Variant Specifies if the radio is a PRO or Non-PRO variant. 0 = PRO, 1 = Non-PRO 0x none Supply Voltage Read the supply voltage of the module in mV units. 0x none 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
