issuing an ATFR and an ATFT command. The frequency will
automatically be saved in non-volatile memory (flash) for this
current channel number.
ATHP
Channel Number
– Select current radio channel number. The
channel number is stored in EEPROM memory.
Range: 1 - 6
1
ATIC
Read Current Draw
Read the current draw in mA. Accuracy is
within 20% of actual current draw.
Range: 0-9999
N/A
ATL
Enable/Disable the LEDs
– 1 = LEDs always off. This reduces
some power consumption. 0 = LED operate normally.
0 or 1
0
ATMT
Protocol Select
– The over-the-air communication protocol.
0=Packetized mode, 5=DART
Range: 0 or 5
5
ATNB
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)
0
ATR3
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 RV-M8-UC will
begin to transmit the data over the air.
Range: 1 - 999
20
20mS is the
default.
ATR8
Frequency Offset.
Used to set the radio on the center of the radio
channel.
Range: -500 to
+500
0

ATRQ
Receiver Signal Level
– Reads the Receiver Signal strength
this instant, and returns the level in dBm.
Range: -40 to –
130 (dBm)
-
ATRS
RSSI
(Receive Signal Strength Indicator) – Returns the signal
level of last received packet. The reading is in dBm. Usable for
relative comparison of signals, but absolute value is within10dB
at -90dBm.
No parameters.
Returns a number :
-50 to –140 (dBm)
varies by model.
none
ATSL
Serial Number
– Reads and returns a unique serial number for
thjs unit.
Read Only
1 - 999999999
unique
ATSM
LPM Operation Enable
– When set to 1, the DTR input line
controls the M8’s low-power operation. When set to 0, the RV-
M8-UC will not go into LPM, regardless of the state of the DTR
pin. When set to 2, the modem is forced into a low-power
mode, disabling the receiver.
Range: 0, 1, 2
0
ATST
Statistics
–
Show the unit’s operational statistics. See Statistics
section of user manual.
0, 1,2, 3, 4, or 5
None
ATTD
Transmit Test Data
– When issued, the modem will begin
transmitting data. The type of data sent is set in the parameter.
Entering a <CR> will terminate the transmission.
0 = Go back to normal
1 = Random
3 = 1010… at ¼ baud rate
4 = TX all 0s
5 = TX all 1s
6 = Test Points ON
7 = Transmit CW
8 = Transmit 1010101…
ATTE
Read product temperature
–
Read the internal temperature of
the unit’s circuit board in degrees Celsius.
-40 to +99
-
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
none
AT&F
Restore Factory
– Restore the factory default values. This
command will not erase the calibration values. After this
command executes, the modem will still be in the CONFIG mode.
