Relay Multiplexer Command Reference
CLOS? (@100,267) !Query state of channel 0, bank 0, card #1 and channel
7, bank 6, card #2
[ROUTe:]FUNCtion
[ROUTe:]FUNCtion
<card_number>, <function>
selects the operating mode of the
multiplexer channels. All channels on the card specified by
card_number
operate
in the specified mode. [ROUTe:] is NOT optional when ROUT:FUNC is used with a
scanning multimeter configuration.
Parameters
Comments
ROUTe is Not Always Optional:
If used with a scanning multimeter configuration,
ROUTe:FUNCtion must be used.
Command Not Always Used:
This command is not required if the status register switch
is configured to the desired mode.
Using the FUNCtion Command:
When using the FUNCtion command to reconfigure
the multiplexer to a different operating mode than the status register switch is
set to, the command must be sent
AFTER
the card is powered up.
One-Wire Mode (WIRE1):
Switches either the HI or LO terminal of a channel in banks
0 through 7, to the one-wire HI COM or one-wire LO COM terminal. When
closing a channel in one-wire mode, the HI or LO line must be selected using
channel_list
. Only one of the 128 one-wire channels can be switched at a time.
Two-Wire Mode (WIRE2):
Switches both the HI and LO terminals of a channel in
banks 0 through 3 or banks 4 through 7 to that bank’s HI COM and LO COM
terminals.
Two-Wire Mode (WIRE2X64):
Switches the HI and LO terminals of a channel in banks
0 through 7 to that bank’s HI COM and LO COM terminals. A maximum of 64
two-wire channels can be switched. This mode is available via E1406A
(Switchbox Rev. A06.00 or later). Prior to this revision, closing control relay 0995
in two-wire mode will change the card configuration to a single 64-channel
two-wire multiplexer.
