38 Getting Started Chapter 1
Channel Addresses Channel addresses (channel_list) have the form (@ccnn) where
cc = switch card number (01-99) and nn = channel numbers (00-63) .
You can address single channels (@ccnn), multiple channels
(@ccnn,ccnn,...), sequential channels (@ccnn:ccnn), groups of
sequential channels (@ccnn:ccnn,ccnn:ccnn) or any combination.
Form C switch channel numbers are 00 through 63. The channels can be
addressed using channel numbers or channel ranges. For a sin gle-module
switchbox, channel ranges can span across the channels. For multiple-
module switchboxes, channel ranges can span across the channels of all
modules.
Use commas (,) to form a channel list or use a colon (:) to form a channel
range. Only valid channels can be accessed in a channel list or c hannel
range. The channel list or channel range must be from a lower channe l
number to a higher channel number. For example, &/26# is
acceptable, but &/26# generates an error. Some example
channel lists/ranges follow.
&/26# ! Close channels 00 and 12 on
card 01
23(1# ! Open channels 03 and 10 on
card 02
23(1# ! Open all channels on card 01
6&$1# ! Scan all channels on card 01
6&$1# ! Scan all channels on card 01
