CS (DO2 Configuration) Command
AT Command: ATCS
Binary Command: 0x1F (31 decimal)
Parameter Range: 0 – 4
Parameter Configuration
0 RS-232 flow control
1 RS-485 TX enable low
2 high
3 RS-485 TX enable high
4 low
Default Parameter Value: 0
Number of bytes returned: 1
Related Commands: RT (DI2 Configuration),
TO (DO2 Timeout)
Minimum Firmware Version Required: 4.27D
<Serial Interfacing> CS Command is used to
select/read the behavior of the DO2 pin signal
(pin 1). This output can provide RS-232 flow
control, control the TX enable signal (for RS-485
or RS-422 operations), or set the default level for
the I/O line passing function.
By default, DO2 provides RS-232
(Clear-to-
Send) flow control.
CT (Command Mode Timeout) Command
<AT Command Mode Options> CT Command is
used to set/read the amount of time before AT
Command Mode terminates automatically. After
CT time of inactivity, the module exits AT
Command Mode AT Command Mode and returns
to Idle Mode. AT Command Mode can also be
exited manually using CN (Exit AT Command
Mode) Command.
AT Command: ATCT
Binary Command: 0x06 (6 decimal)
Parameter Range: 0x02 – 0xFFFF
[x 100 milliseconds]
Default Parameter Value: 0xC8 (200 decimal,
20 seconds)
Number of bytes returned: 2
DC (Disconnect) Command
<Networking> Use DC Command (when in Multi-
Streaming Mode, MD > 0) to explicitly force a
disconnect of an active exclusive connection. If
MD = 1, the base module will force the
disconnect of an exclusive connection. If MD = 2,
the remote module will send a “Disconnect
Request Packet” to the base module.
AT Command: ATDC
Binary Command: 0x37 (55 decimal)
Related Commands: CB (Connection Duration
Timeout), CE (Connection Inactivity Timeout),
MD (RF Mode)
Minimum Firmware Version Required: 4.30
DR (DI3 Configuration) Command
AT Command: ATDR
Binary Command: 0x2C (44 decimal)
Parameter Range: 0 – 4
Parameter Configuration
0 Disabled
1 DI3 I/O passing enabled
2 Connect on low
3 Disconnect on high
4 Connect and Disconnect
Default Parameter Value: 0
Number of bytes returned: 1
Related Commands: CD (DO3 Configuration),
CO (DO3 Timeout)
Minimum Firmware Version Required: 4.30
<Serial Interfacing> Configure DI3 (pin 2,
SLEEP) for I/O line passing (use with CD=1 or 2
and CO) or controlling connection status (use
with MD=1 or 2).
