The 3456A's Hp·ID connection is made by an Hp·IB
Interface cable to the 24 pin HP·ID connector located at
the rear panel. A typical interconnection of Hp·ID is
shown in Figure 2-3 in which system interconnection is
made by three Hp·ID Interface Cables. The ends of the
cables have both a male and female connector to enable
connections to other instruments and cables. As many
as 15 instruments can be connected by the same inter·
face bus. However, the maximum length of cable that
can effectively be used to connect a group of in·
struments should not exceed 2 meters (6.5 feet) times the
number of instruments to be connected, or 20 meters
(65.6 feet), whichever is less. For a pictorial view of the
Hp·ID connector and its pin designation, refer to Figure
2-4.

2-21. The Hp·J8 "talk" and "listen" address of the
Model 3456A is set by the instrument's address switch,
located at the rear panel. The talk and listen address is a
5-bit code which is selected to provide a unique address
for each HP-ID instrument. The 3456A normally leaves
the factory with the address switch set to decimal code
"22." The corresponding ASCII code is a listen address
code of "6" and a talk code of "V.
for the factory address switch setting.
