Figure 2-3 shows how to connect the analog bus between multiple
multiplexer modules and to the HP E1326A Multimeter. Use the cables
shipped with the multiplexer modules to connect the analog bus of the
multiplexer modules. Use the cable shipped with the HP E1326A
Multimeter to connect the analog bus of the multiplexer module to the
Multimeter input.
These cables are needed to connect the multiplexer when mounted in the
E1403 Module Carrier to the E1411A/B DMM in a C-size cardcage. They
must be ordered separately.
•
Connecting E1411 to RELAY MUX's: use E1326-61611 (long
analog bus cable).
•
Connecting RELAY to RELAY or RELAY to FET MUX: use
E1400-61605.
The address switch (LADDR) factory setting is 112. You may have
changed the setting during module installation. Valid address values are
from 0 to 255. Refer to the "HP 75000 Series B System Installation and
Getting Started Guide" or the "HP E1406 Command Module Manual" for
addressing information. Otherwise, to change the setting, use the following:
Isolation jumper JM1 connect the Low (L) and Guard (G) commons to each
