CO (DO3 Timeout) Command
<Serial Interfacing> DO3 (Data
Output 3) output will return to
default after no DI3 (Data Input
3) status information is received
during the timeout period.
Use with CD = 1 or 2, DR = 1.
CS (DO2 Configuration)
Command
<Serial Interfacing> CS
Command is used to select the
behavior of the DO2 (Data
Output 2) pin signal. 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
<Command Mode Options> CT
Command is used to set the
amount of time of inactivity
before AT Command Mode
automatically terminates. After a
CT time of inactivity, the module
exits AT Command Mode and
returns to Idle Mode. AT
Command Mode can also be exited manually using the CN (Exit AT Command Mode)
Command.
DC (Disconnect) Command
<Networking & Security> DC
Command is used (when in
Multi-Streaming Mode (MD = 1
or 2)) to explicitly force the
disconnection of an active
exclusive connection. If MD = 1,
the base module will force the
disconnection of an exclusive connection. If MD = 2, the remote module will send a
“Disconnect Request Packet” to the base module
DR (DI3 Configuration)
Command
<Serial Interfacing> DR
Command is used to 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).
