Returned

Factory

Default

Guard Time After. Set required DI pin silent time after the

Command Sequence Characters of the AT Command Mode

Sequence (BT+ CC + AT).

0x02 – 0xFFFF

[x 1 ms]

AT Command

Mode Options

0x1F4

(500d)

Interface Data 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, flow control may need to be observed to prevent DI

buffer overrun.

0 – 6

(1200 - 57600 bps)

Serial

Interfacing

Set to equal

radio modem’s

fixed RF data

rate.

Number of Bits. (7 or 8) – Sets number of data bits per

character (bits between start and stop bits).

0 – 1

0 = 7 bits

1 = 8 bits

Serial

Interfacing

Guard Time Before. Set required DI pin silent time before the

Command Sequence Characters of the Command Mode

Sequence (BT+ CC + AT).

0 – 0xFFFF

[x 1 ms]

AT Command

Mode Options

0x1F4

(500d)

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).

0x20 – 0x7F

AT Command

Mode Options

0x2B

(plus sign (+) in

ASCII)

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.

0x02 – 0xFFFF

[x 100 ms]

AT Command

Mode Options

0xC8

(200d)

Software Flow Control. Enable serial software flow control on

the radio modem. (Hardware flow control (CTS

) is on by

default.)

0 - 1

0 = disable

1 = enabled

Serial

Interfacing

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.

0 – 0xFFFF

[x 100 ms]

Sleep

(Low Power)

0xFFFF

(no wake-up

Initializer will be

sent)

Modem VID. Read radio modem VID (Vendor Identification

Number). Only radio modems with matching VIDs can

communicate with each other.

0 – 0x7FFF

(above this range is Read-only)

Networking 2 0x3332

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).

0 – 0xFF

[x 100 ms]

Sleep

(Low Power)

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.

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

PW Pin Wake-up. Enable pin wake-up from Cyclic Sleep Mode.

0 – 1

0 = disabled

1 = enabled

Sleep

(Low Power)

RT DI2 Configuration. Enable RTS

Mode

0 - 1

0 = Disabled

1 = RTS

flow control

Serial

Interfacing

SB Stop Bits. Set number of stop bits.

0 – 1

0 = 1 stop bit

1 = 2 stop bits

Serial

Interfacing

SM Sleep Mode. Specify Sleep Mode settings.

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)

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 [refer to SM
