OPEN
[ROUTe:]OPEN <channel_list>
[ROUTe:]OPEN? <channel_list>
See examples.
All relays on all modules are set to the open position.
The limits on the relay numbers in the <channel_list> portion of this command
depend on the model number of the relay module(s) specified in the <chan-
nel_list>. The syntax of a <channel_list> is described by the following diagram:
<NR1>

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 relay number or a range of relay numbers. A range of relay numbers is
indicated by two relay numbers separated by a “:” character.
A relay number may have one, two, or three dimensions depending on the
architecture of the relay module containing the relay. For example, the VX4350
contains 64 SPDT relays. Only one-dimensional relay numbers are supported for
this module. The VX4380 Module contains four 4 × 16 2-wire matrices.
Three-dimensional channel numbers are supported for this module. The first
specifies the row, the second specifies the column and the third specifies the
matrix containing the relay. Multi-dimensional relay numbers are represented by
integers separated by “!” characters. See the manuals for the VX4330, VX4350,
