Once the RV-M8-UC  is ready to be used on a DART network, make sure all of 
these settings are set. 

ATMT 5   

Hyper/DART modem type

  

SID xx

On RV-M8-UC , the periodic reporting must be enabled.  This command is set at 
the factory to enable GPS periodic reporting.  

GXF 1 1 

Enable periodic GPS tracking reporting

 

 

 

7.  Data Transmission 

To transmit data, send one or more bytes of data into the serial port of the 
modem.  When a full packet of data has been collected into the internal buffer of 
the modem, or when there is a pause in the data, the modem will automatically 
key its transmitter, and send the data over the air if the modem is within range of 
a base station.   

Serial Port Baud Rate 

While the RV-M8-UC modem is transmitting and receiving data on the DART 
network, the user may continue to send more data into the RV-M8-UC

.

 Because 

the buffers in the RV-M8-UC are full-duplex, the serial port data rate and the 
over-the-air data rates are independent.  The serial port baud-rates may be set 
slow to accommodate legacy equipment, or set at high-speed to minimize 
latency.   

 

8.  Debug Related Commands 

Bench Testing 

(Must be in command mode to test.   Enter +++ at the keyboard to put unit into config/test mode.) 

ATTD  x 

Various transmit test routines.   
0 = Go back to normal mode. Stops the test. 
1 = Random data transmit. 
3 = Force PLL to fast lock mode 
4 = Transmit all 0s 
5 = Transmit all 1s
