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. For the
MURS version, the ATPO setting is limited to 40%.
0-110
100
ATR0
Symbol Peak Deviation – Set the peak FM deviation of
the transmit symbols. Note: This can be a negative number
to invert the modulation.
Range: -1000 – 1000
120**
ATR1
Select CD pin output signal – CD may be RF carrier
detect, or modem data detect.
Range : 0 - 2
2 = Always assert CD
1 = Data CD
0 = RF CD
1
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 10 for information on how to set the OTA
baud rate.
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
10=14.4k 4L
3
ATR3
Serial Port time out – Number of mS of no activityon the
serial port before transmitting the data in its buffer.
Range: 1 - 5000
20 (mS)
ATR5
Preamble length – The number of bytes to send over-the-
air in the pre-amble.
Range: 3 - 255
4**
(Varies based
on data rate
and radio
type. 7 typical)
ATR8
Frequency Offset. Used to set the radio on the center of the
radio channel.
Range: -500 to +500
0**
ATRB
Number of retries. If this modem does not get an ACK
back when it sends data, this is the number of times it will
re-transmit the packet and wait for an ACK. 0=disabled
feature.
Range: 0-99
0
(ACKs are not
used)
ATRF
RF Carrier Required – When enabled, there must be RF
energy on the channel for the modem to output data.
Streaming data mode only. 1-RF required. 0=ignore RF
energy when receiving.
Range: 0, 1
0 (no RF
required)
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
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. Default is OFF (1).
0= Remote Access on
1=Remote Access off
1
ATSL
Serial Number – Reads and returns a unique serial
number for thjs unit.
Read Only
1 - 999999999
unique
ATSH
Show – Display the configuration of the modem. This will
return a page of ASCII characters, showing the main
configuration parameters.
none
None
ATSM
Sleep Mde Operation Enable – When set to 1, the DTR
input line controls the RV-M7’s low-power operation.
When set to 0, the RV-M7 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 and
