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 TK8 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

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

ATSM
LPM Operation Enable
–
When set to 1, the DTR input line
controls the M8
’s low
-power operation. When set to 0, the TK8
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

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.
