Channels

The 

 option is different depending on whether you are configuring a Digital Input 

or a Digital Output/Relay channel. The 

 option for Digital Input lists all the local 

Digital Output channels or output serial signal pins that it is associated with. Digital Input can be 
connected to multiple local Digital Output or Relay channels or output serial signal pins. However, a 
Digital Output can only be associated with one Digital Input channel or input serial signal pin. The 

 option for Digital Output configures the specific local Digital Input channel or 

input serial signal pin on the same IOLAN that it is to be connected to. 
For a description of the SSL/TLS parameters (not available when 

 is configured), 

.

Configure the following parameters:

When enabled, the digital channel 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

Default: Disabled

When enabled, the channel/serial signal pin will wait for connections to be 

initiated by another I/O channel or a TCP/IP application.
Default: Enabled

The TCP port that the channel/serial signal pin will use to listen for incoming 
connections.
Default: 2000 for channel 1, then increments by one for each channel
