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.
