XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00
CN (Exit AT Command Mode) Command
<Command Mode Options> CN Command is
used to explicitly exit AT Command Mode.
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 sets
the amount of time before AT Command Mode
terminates automatically. After a CT time of
inactivity, the modem exits AT Command Mode
and returns to Idle Mode. AT Command Mode can
also be exited manually using CN (Exit AT
Command Mode) Command.
DC (Disconnect) Command
<Networking and 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
modem will force the disconnection of an
exclusive connection. If MD = 2, the remote
modem will send a “Disconnect Request Packet”
to the base modem.
