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:

<channel_range>

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,
