RV-M7 Technical Manual
Protocol Select – The over-the-air communication protocol.
0=Packetized mode, 2=Streaming data.
Unit Address – Configures the individual; address for this unit.
Each digit may be a 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,or F. Note:
FF is interpreted as a group. See addressing section.
Parity – Selects parity format. Settings 0-4 transfer 8-bits over
antenna port and generate the parity bit on the RF receiving
side.
Range: 0 – 5
0 = none
1 = Odd
2 = Even
3 = Mark (1)
4 = Space (0)
Number of Data Bits – Set/read the number of data bits.
Stop Bits – Selects the number of stop bits.
Packet Error Display – Shows statistics to compute packet-
error rate. Displays Packets Per Minute (PPM) and a running
total.
1 = reset counters
2 = Stop PER display
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.
Symbol Peak Deviation – Set the peak FM deviation of the
transmit symbols. Note: This can be a negative number to
invert the modulation.
Select CD pin output signal – CD may be RF carrier detect,
or modem data detect. If set to 2, CD will be asserted when
on-line, and negated in the command mode.
Range : 0 - 2
2 = Assert CD online
1 = Data CD
0 = RF CD
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 7.6 for information on how to set the OTA baud rate.
With firmware C22 and higher, you may enter the actual baud
rate instead of the index number.
Range:
0 = 800 5 = 9600 2L
1 = 1200 6 = 19200 4L
2 = 2400 7 = 5142 2L
3 = 4800 8 = 9600 4L
4 = 8000 4L 9 = 2000 2L
Serial Port Time Out – The time in milliseconds for the serial
port to time out. When data is entering the serial port, and
this amo0unt of time passes with no more data, the M7 will
begin to transmit the data over the air.
Preamble length – The number of bytes to send over-the-air
in the pre-amble.
