• Opening Channels: To open:
– a single channel, use [ROUTe:]OPEN (@ccnn)
– for multiple channels, use [ROUTe:]OPEN (@ccnn,ccnn)
– sequential channels, use [ROUTe:]OPEN (@ccnn:ccnn)
– a group of sequential channels, use [ROUTe:]OPEN
(@ccnn:ccnn,ccnn:ccnn)
– or any combination.
Opening order for multiple channels with a single command is not
guaranteed.
• Opening the DT Tree Switch: Use channel numbers 93 to open the
DT Tree Switch.
