# Bytes
Returned
Factory
Default
AT
Guard Time After. Set required DI pin silent time after the
Command Sequence Characters of the AT Command Mode
Sequence (BT+ CC + AT).
Range: 0 – 0xFFFF
(x 1 ms)
AT Command
Mode Options
2
0x1F4
(500d)
BD
Baud Rate. Set serial data rate (baud rate at which radio modem
interfaces with host).
Serial data rate is different than RF data rate which is fixed and
factory-set. If the serial data rate is set higher than RF data rate,
may need to be observed to prevent DI buffer overrun.
Range: 0 – 6
(1200 - 57600 bps)
Serial
Interfacing
1
Set to equal radio
modem’s fixed RF
data rate.
BI
Number of Bits. (7 or 8) – Sets number of data bits per character
(bits between start and stop bits).
Range: 0 – 1
0 = 7 bits
1 = 8 bits
Serial
Interfacing
1 1
BT
Guard Time Before. Set required DI pin silent time before the
Command Sequence Characters of the Command Mode Sequence
(BT+ CC + AT).
Range: 0 – 0xFFFF
(x 1 ms)
AT Command
Mode Options
2
0x1F4
(500d)
CC
Command Sequence Character. Set the ASCII character to be
used between Guard Times of the AT Command Mode Sequence
(BT+ CC + AT). The AT Command Mode Sequence enters the
radio modem to AT Command Mode (from Idle Mode).
Range: 0x20 – 0x7F
AT Command
Mode Options
1
0x2B
(plus sign (+) in
ASCII)
CT
Time before Exit AT Command Mode. Set time period of inactivity
(no valid commands received) after which radio modem
automatically exits from AT Command Mode.
Range: 0x02 – 0xFFFF
(x 100 ms)
AT Command
Mode Options
2
0xC8
(200d)
FL
Software Flow Control. Enable serial software flow control on the
radio modem. (Hardware flow control (
) is on by default.)
Range: 0 - 1
0 = disable
1 = enabled
Serial
Interfacing
1 0
HT
Time before Wake-up Initializer. Set time period of inactivity (no
serial or RF data is sent or received) before a Wake-up Initializer is
sent. Base station tracks awake-status of remote radios. HT of
base radio should be set shorter than ST of remote radios.
Range: 0 – 0xFFFF
(x 100 ms)
Sleep
(Low Power)
2
0xFFFF
(no wake-up
Initializer will be
sent)
ID
Modem VID. Read radio modem VID (Vendor Identification
Number). Only radio modems with matching VIDs can
communicate with each other.
Range: 0 – 0x7FFF
(above this range is
Read-only)
Networking 2
0x3332
LH
Wake-up Initializer Time. Set time of the Wake-up Initializer used to
wake remote radios that are in cyclic sleep mode. Time of Wake-up
Initializer should be longer than that of the remote radio’s cyclic
sleep cycle (SM 3 - 8).
Range: 0 – 0xFF
(x 100 ms)
Sleep
(Low Power)
1 1
NB
Parity. Select parity format. Settings 0-4 transfer only 8 bits out the
antenna port and generate the parity bit on the radio modem
receiving side.
Range: 0 – 4
0 = 8-none-1, 7-any-1
1 = 8-even-1
2 = 8-odd-1
3 = 8-mark-1, 8-none-2
4 = 8-space-1
Serial
Interfacing
1 0
PW
Pin Wake-up. Enable pin wake-up from Cyclic Sleep Mode.
Range: 0 – 1
0 = disabled
1 = enabled
Sleep
(Low Power)
1 0
RT
DI2 Configuration. Enable
Mode (
/CMD signal - pin 5 of
OEM RF Module).
Range: 0 - 1
0 = Disabled
1
= flow control
Serial
Interfacing
1 0
SB
Stop Bits. Set number of stop bits.
Range: 0 – 1
0 = 1 stop bit
1 = 2 stop bits
Serial
Interfacing
1 0
SM
Sleep Mode. Specify Sleep Mode settings.
Range: 0 – 8
0 = No sleep
1 = Pin Sleep
2 = Serial Port Sleep
3 to 8 = Cyclic intervals
ranging from 0.5
to16.0 seconds
Sleep
(Low Power)
1 0
ST
Time before Sleep. Set time period of inactivity (no serial or RF
data is sent or received) before activating Sleep Mode. Use with
Cyclic Sleep and Serial Port Sleep. (see SM Command)
Range: 0x10 – 0xFFFF
(x 100 ms)
