Relay Multiplexer Command Reference
[ROUTe:]
Three-Wire Mode (WIRE3):
Banks are paired 0/4, 1/5, 2/6, and 3/7. Switches both the
HI and LO terminal of a channel in bank 0-3, to that bank’s HI and LO COM
terminals. Also switches the LO terminal of the channel in pair bank 4-7 to that
bank’s LO COM terminal.
When closing a channel in three-wire mode, only the lower bank (0-3) is
specified and the upper bank pair (4-7) will automatically close. A maximum of
32 three-wire channels can be switched. Selecting an upper bank (4-7) channel
causes an error.
Four-Wire Mode (WIRE4):
Banks are paired 0/4, 1/5, 2/6, and 3/7. Switches both the
HI and LO terminal of a channel in bank 0-3, to that bank’s HI COM and LO COM
terminals. Also switches the HI and LO terminal of the channel in pair bank 4-7,
to that bank’s HI and LO COM terminals. When closing a channel in four-wire
mode, only the lower bank (0-3) is specified, and the upper bank pair (4-7) will
automatically close. A maximum of 32 four-wire channels can be switched.
Selecting an upper bank (4-7) channel causes an error.

Example
Configuring Multiplexer Mode
This example configures card 01 of a single-module switchbox to four-wire mode.
FUNC 1,WIRE4 !Configures card #1 to four-wire mode
In three-wire mode, do not connect user wiring to the HI terminal
in the upper bank pair (4-7). This terminal is switched during
three-wire operation, and dependent on relay configurations,
could be switched to
the HI COM terminal.
