Configuring Async Port Features
RS-485 CLI Support 9-11
RS-485 CLI Support
The LX-1004 Series supports an RS-485 option. Commands and
show screens have been added to support this feature.
These Asynchronous Mode commands allow you to configure the
RS-485 for Duplex Mode (half or full duplex), Transmitter Mode,
or Echo Mode.
X To configure RS-485 duplex mode
Use the following duplex mode commands to set the
RS-485 port to a duplex mode of either half or full
(
default).
Examples Async1:0 >> rs485 duplex mode half
Async1:0 >> rs485 duplex mode full
X To configure RS-485 echo mode
Use the enable or disable (
default) commands in RS-485
echo mode when the port is in half-duplex mode.
L The echo mode is valid only if duplex mode is set to half.
Examples Async1:0 >>rs485 echo mode enable
Async1:0 >>rs485 no echo mode
X To set the RS-485 transmitter to always/RTS enable
Use the rs485 transmitter always enable command to
use full-duplex applications such as RS-422 or RS-485 4-wire
Master modes in which tri-state control of the transmitter is
not required.
L This parameter is valid only if duplex mode is set to full.
Set this command to rs485 transmitter rts enable to use
the RTS modem control signal to enable the RS-485 interface,
and provide backward compatibility with existing software.
Syntax
Examples Async1:0 >>
rs485 transmitter always enable
rs485 transmitter [always|rts] enable
