Specifying Channel Lists and Scan Lists
A command’s channel list (<ch_list>) or scan list (<scan_list>) parameter
is used to specify a single channel, multiple channels, or a range of
channels. The channel and scan lists must be preceded with the "@"
symbol and must be enclosed in parentheses. The following commands
demonstrate how the channel list parameter is used:
ROUT:CLOS (@1010) - close channel 10
ROUT:CLOS (@1010,1012,1015) - close channels 10, 12, and 15
ROUT:CLOS (@1005:1010,1015) - close channels 5-10, and 15
When specifying a range of channels, the first and last channels in the
range must be valid. Any invalid channels within the range are ignored
(no error is generated).
The Analog Bus relays (numbered 911, 912, 913, etc.) on the multiplexer
and matrix modules are ignored if they are included in a range of
channels. An error will be generated if an Analog Bus relay is specified
as the first or last channel in a range of channels.
Refer to “Scanning” later in this chapter for additional information
creating/using a scan list.
