Connecting a single I-7523 modules and two
HP34401A

The following diagram below shows how to connect a single PC
connected to two remote HP34401As on an RS-485 network. The
I-7520 module is used to convert the RS-232 signal from to PC to
an RS-485 signal. The I-

7523 module is used as an “Addressable

RS-

232 converter” for the HP34401A, since there is no address

setting on theHP34401A. Two HP34401A can be connected to a
single I-7523 module.
