SCAN
[ROUTe:]SCAN <channel_list>
N/A
No scan list is defined.
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:

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 user manuals for the VX4320,
VX4330, VX4350, and VX4380 for more information on the format of relay
numbers for these modules.
