7. Commands to Configure Radio Operation

Command	Command Description	Parameters	Factory Default
ATBD	Baud Rate – Sets serial com port baud rate (bps). Over-the-air (throughput) baud rate is set with ATR2 command. If a PC’s serial baud rate is set higher than the fixed over-the-air baud rate of the module, hardware handshaking may be required.	Range: 0 – 7 0 = 1200 5= 38400 1 = 2400 6=57600 2 = 4800 7=115200 3 = 9600 4 = 19200	3
ATDT	Destination Address to call– Sets address of the modem to send data to. Note, this parameter is entered in HEX format. Each digit may be a 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,or an F.	Range: 0-FFFF	1234
ATF	Display frequencies – Display all of the frequencies programmed into all of the channel memories.		N/A
ATFT	Transmit Frequency – Program the transmit frequency for this channel. Enter in Hz or in MHz. The frequency will automatically be saved in non-volatile memory (flash) for this current channel number.	Range: See product data sheet. For MURS products, frequency cannot be changed.	See product data sheet.
ATFR	Receive Frequency – Program the receive frequency for this channel. Enter in Hz or MHz. The frequency will automatically be saved in non-volatile memory (flash) for this current channel number.	Range: See product data sheet. For MURS products, frequency cannot be changed.	See product data sheet.
ATFX	TX and RX Frequency – Program the receive and transmit frequency for this channel. Enter in Hz or MHz. Same as issuing an ATFR and an ATFT command. The frequency will automatically be saved in non-volatile memory (flash) for this current channel number.	Range: See product data sheet.	N/A
ATHP	Channel Number – Select separate channels to minimize interference between multiple sets of modules operating in the same vicinity.	Range: 1 - 6	1
ATMK	Address Mask – Configures local and global address space. Each digit may be a 0,1,2,3,4,5,6,7,8,9.	Range: 0000 - FFFF	FFFF
ATMY	Unit Address – Configures the individual; address for this unit. Each digit may be a 0,1,2,3,4,5,6,7,8,9.	Range: 0000 - FFFF	1234
ATPO	RF Power Output. Set or show the RF power output setting. Value is in percent, from 0% to 100%. Use and RF wattmeter to confirm the power setting, and adjust the % accordingly to obtain the desired RF power level.	0-100	100
ATR2	Over-The-Air bit rate - This is the data rate the radio uses to send data over the air. All RF modems in the network must use the same over-the-air baud rate. Refer to section Error! Reference source not found. for information on how to set the OTA baud rate.	Range: 0 = 800 7 = 5142 2L 5 = 9600 2L 3 = 4800 1 = 1200 8 = 9600 4L 6 = 19200 4L 4 = 8000 4L 2 = 2400 9 = 2000 2L	3
ATRV	Disable Remote Access – When enabled (set to a 0), the modem will respond to over-the-air RPR requests, Pings, and over-the-air commands.	0 = Remote Access on 1 = Remote Access disabled	1
ATSL	Serial Number – Reads and returns a unique serial number for thjs unit.	Read Only 1 - 999999999	unique
ATSH or SHOW	Show – Display the configuration of the modem. This will return a page of ASCII characters, showing the main configuration parameters.	none	None
ATST	Statistics – Show the unit’s operational statistics. See Statistics section of user manual.	0, 1,2, 3, 4, or 5	None
ATVB	Read DC input Voltage– Returns the DC input voltage reading, in mV (12500 = 12.5VDC input).	None	none
ATVR	Firmware Version – Returns firmware version currently loaded on the module.	Read Only, 3 characters	Current version
REPEAT n	Enable/Disable Store and Forward Repeating – 0=disabled, 1 – enabled (repeat everything)	0 or 1	0 (Off)
PING	Ping another modem. Format is PING xxxx, where xxxx is the ID of the modem to ping. If remote access is enabled on xxxx, it will respond.	XXXX	-
SHOW	Show/display an overview of the radio’s configuration.	None	-

** indicates values that are calibrated in the factory and are unit-specific. If the “Radio Type” is changed, these will need to be re-calibrated.

GPS Additional Commands to Configure GPS and Tracking Features

The following commands are unique to the –GX version of the M7. When you execute any of these commands, the new parameter is automatically stored in EEPROM.

Command	Command Description	Parameters	Default
GX	Display GPS settings. Show an overview of the current GPS features and configurations in the M7 GX.	-	-
GPS	GPS Operation Mode. Read/Set the GX version’s Operating mode.	0 - 6	1
GPS&F	Reset all GPS (-GX version) parameters. Set the GX version’s Operating mode to GPS mode 4, and sets all GPS parameters to factory defaults. It does not erase frequency or other radio-related parameters.	-	-
IDLERATE	IDLE TX Interval. Set the number of seconds between position transmissions when the unit is idle (has not moved more than TRIGDX meters).	0-9999 seconds	10
KEYPHRASE	Privacy Security Key Code. Set the privacy key for this device. It must be the same key as used on all other Raveon products in your system. It secures radio transmissions from unauthorized reception. Set it to 0 to disable security encryption of data.	2-16 ASCII characters.	“RAVEON”
PREFIX	ID Prefix. Set an ID prefix. The prefix is 1-8 characters that will be put in front of the ID when reporting an ID as a waypoint name. A dash means no prefix. Default is a capitol letter V.	1-8 ASCII characters Set it to “0” for no prefix.	V
SLOTTIME	TDMA Slot duration. Configure the width of a TDMA slot. 50mS increments.	50 - 1000	200
SLOTNUM	TDMA Slot Number. Configure the slot number that this radio will use to send its data in.	1-9999	The MYID of the unit
TRIGBITS	I/O Change Reporting. Which bits are used as transmission triggers. This is a HEX number. Bit 0 is IN0, bit 1 is IN1….	0-FF	0
TDMATIME	Set/read TDMA Frame time. The length of one TDMA time frame, in seconds. M7’s may transmit once per frame, and only in their preset time-slot.	1-3599	10
TRIGPOL	Polarity of the input bits. 0 = normal active high operation(causes unit to transmit when it goes high), 1 = Inverted, active low. This is a HEX number. Bit 0 is IN0, bit 1 is IN1….	0-FF	0 Active high
TRIGEX	Report on change. Sets which input bits cause a report on change. If a particular bit is a 1, then it will trigger a report when it changes. The input bit must also be enable with the TRIGBITS. This is a HEX number. Bit 0 is IN0, bit 1 is IN1…	0-FF	0
TRIGDX	Distance trigger. Set a distance (in meters) threshold beyond-which the unit will transmit its position and status. If set to 0, the unit always reports at the TXRATE. If set to an distance greater than zero, then the unit reports at the TXRATE intervals if it has moved this distance since the last report. If it has not moved, it will still report its position, but at the rate set by IDLERATE. If IDLERATE is set t 0, then the unit will not report its position when not moving.	0-999	0
TRIGSPEED	Speeding Report. Set a speed (in kilometers/hour) threshold above-which the unit will begin reporting its position and status. Set to 0 to disable this feature.	0-999	0
TXRATE	GPS Report Rate. Set number of seconds between GPS reports. This is also the rate at which the internal GPS will measure position, speed, etc. Even if the unit is not moving, the GPS periodically measures position and speed to determine if it has triggered a speed or position transmission.	1 - 9999	10
