IOLAN DS1/TS2 CLI Reference Guide, Version 4.3
Set IOChannel IOExtension
Description Configures the I/O extension options that allow you to connect the Digital Input 
channel or input serial signal pin (when the line is configured for signal-io) to Digital 
Output/Relay channels or output serial signal pins (when the line is configured for 
signal-io) on the same IOLAN, remote IOLAN(s), and/or TCP/IP applications running 
on local hosts.

Options
<channel>
Specify the Digital/Relay channel or serial signal pin that you are configuring the I/O 
extension for. The channel can be d1, d2, d3, d4, r1, r2, depending on the model. The 
serial signal pins are dsr, dcd, or cts for input and dtr or rts for output.
enabled
When enabled, the digital input channel or DSR/DCD/CTS input serial signal pins can 
be connected to:
z
A Digital output or relay (if the I/O model supports relay) channel on the same 
IOLAN
z
Output Serial Signal Pins (DTR/RTS)
z
A Digital output channel on another IOLAN(s) or output serial signal pins 
(DTR/RTS) on another IOLAN(s)
z
A TCP/IP application(s) running on a host on the network
When enabled, the digital output/relay channel or DTR/RTS output serial signal pins 
can be associated with a digital input channel or input serial signal pins.
Default: Disabled
keepalive
Enables a per-connection TCP keepalive feature. After the configured number of 
seconds, the connection will send a gratuitous ACK to the network peer, thus either 
ensuring the connection stays active OR causing a dropped connection condition to be 
recognized.
This parameter needs to be used in conjunction with server parameter, 
monitor-connection-every. The interval determines how long the IOLAN will wait 
during inactivity before "testing" the connection. It should be noted that if a network 
connection is accidentally dropped, it can take as long as the specified interval before 
anyone can reconnect to the serial port.
