Connecting Switchbox Channels to Direct Terminals

The direct terminals provide direct access to closed channels. There is a direct terminal for each bank, Bank 0 and Bank 1. Closing any channel in Bank 0 (channels 00 to 07) connects the channel to the Bank 0 direct terminal. Closing any channel in Bank 1 (channels 08 to 15) connects the channel to the Bank 1 direct terminal. You can isolate the two banks from each other, and from the analog bus connector and tree terminals, with the SCAN:PORT NONE command. This command opens the A and B tree isolation switches. Figure 3-1 shows how to connect channels 02 and 09 of a single module to their respective direct terminals. Only one channel can be closed at a time.

SCAN:PORT NONE

Opens Tree Isolation Switches.

CLOSe (@102)

Closes channel 02 on card 01.

CLOSe (@109)

Opens 02 then closes 09.
