Installation guide

146
termination={on|off}
Applies when the serial port is running in EIA-485 mode only.
Determines whether termination and biasing resistors are used across
the lines.
on
Termination and biasing resistors are enabled across the
lines. Termination should be set to "on" if this node is an
endpoint of the 485 network. Biasing should be used in at
least one unit in a two-wire environment.
off
Termination and biasing resistors are disabled across the
lines.
The default is "off."
Examples Configure standard EIA-232 communication
#> set switches port=1 mode=232
Configure a half-duplex EIA-485 endpoint
#> set switches port=1 mode=485 wires=two
termination=on
Configure a full-duplex 422 interior node
#> set switches port=1 mode=485 wires=four
termination=off
