Field Descriptions
The Local conn ec tion option is different depending on whether you are configuring a Digi tal Input
or a Digital Output/Relay channel. The Local connection option for Digital Input lists all the local
Digital Output channels or output seri al 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 sign al pin. The
Local connection option fo r Digital Output configures the specifi c local Dig ital Input channel or
input serial signal pin on the same IO LAN that it is to be connected to.
For a description of the SSL/TLS parameters (not available when Local connection is configured),
see SSL/TLS Settings Tab Field Descriptions on page 123.

Digital Input/DSR/DCD/CTS Digital Output/Relay/DTR/RTS

Configure the following param eters:
Enable I/O
extension When enabled, the digital channel can be connected to:
zA Digital output or relay (if the I/O model supports relay) channel on the
same IOLAN
zOutput Serial Signal Pins (DTR/RTS)
zA Digital output channel on another IOLAN(s) or output serial sign al pins
(DTR/RTS) on another IOLAN(s)
zA TCP/IP application(s) running on a host on the network
Default: Disabled
Listen for
connection 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
Input TCP Port The TCP port that the channel/serial signal pin wil l use to listen for incoming
connections.
Default: 2000 for channel 1, then increments by one for each channel
