Connecting Switchbox Channels to Tree Terminals for Making Measurements

Connect external multimeters to the A tree terminal. The SCAN:PORT ABUS command closes the appropriate FETs on the A and B tree isolation switches, so that the channels that are closed are connected to both the analog bus connector and the tree terminals. The A tree terminal is connected to the H, L, and G lines, and the B tree terminal is connected to the I +, I- and G lines. Figure 3-2 shows how to connect multimeters to measure channel 02 and channel 09.

SCAN:PORT ABUS

Enables tree isolation switches.

CLOS (@102)

Close channel 02 on card 01.

CLOS (@109)

Open 02, close 09.
