VX4380 256-Crosspoint Relay Matrix Module User Manual
A one dimensional <channel_spec> consists of a single ASCII-encoded decimal
integer. The value of a one dimensional <channel_spec> can be determined from
a three dimensional <channel_spec> by using the following formula:
((section - 1) × 64) + ((row - 1) × 16) + column
where variables “section”, “row”, and “column” are section, row and column
numbers specified in a three dimensional <channel_spec>.
For example, the channel spec 3!10!2 specifies the relay that connects row 3 to
column 10 in section 2. The equivalent one dimensional <channel_spec> is equal
to ((2–1) × 64) + ((3–1) × 16) + 10 = 106.
The syntax of a <list_of_lists> is supported on the VX4350 and VX4380
modules and is described by the following diagram:
<list_of_lists>
( @ (
,
) )<module_name>
<channel_range>
,
,
Each <channel_list> is identified by the @ character and represents a single
location in the scan sequence. The syntax contains a list of channels that are
operated simultaneously when the single location in the scan sequence is
reached.
A maximum of eight channels may be specified in each <channel_range>.

This command defines a list of relay closures to sequence through. This list is
called a scan list. When the ROUTe:SCAN <channel_list> command is received,
all relays in this list are opened. In addition to defining a scan list, a trigger
source must be specified using the TRIGger[:SEQuence]:SOURce command.
