VX4380 256-Crosspoint Relay Matrix Module User Manual
OPEN
[ROUTe:]OPEN <channel_list>
[ROUTe:]OPEN? <channel_list>
See examples.
All relays on all modules are set to the open position.
The syntax of a <channel_list> is described by the following diagram:

A module_name is an ASCII string that has been associated with a relay module
in a [ROUTe:]MODule[:DEFine] command. A channel_range may consist of a
single <channel_spec> or a range of <channel_spec>s. A range of <chan-
nel_spec>s consists of two <channel_specs> separated by a colon (:) character.
One, two and three dimensional <channel_spec>s are supported for the VX4380.
A three dimensional <channel_spec> consists of three ASCII-encoded decimal
integers separated by exclamation point characters (!). The first integer specifies
a row, the second a column, and the third a section of the VX4380. For example,
<channel_spec> 2!3!4 specifies the relay that joins row 2 to column 3 in section
4 of the VX4380.
Two dimensional <channel_spec>s consist of two ASCII-encoded decimal
integers separated by an exclamation point character. The first integer specifies a
row and the second specifies a column. When a two dimensional <chan-
nel_spec> is issued, the section number defaults to 1. For example, <chan-
nel_spec> 4!15 specifies the relay that joins row 4 to column 15 in section 1.
