2-24. Remote programming sources for the 3320B Option
007 include the -hp- Model 3260A Marked Card
Programmer, the -hp- 9800 series Calculators, and the -hp-
2100 series computers. The -hp- 11235A Adapter must be
used to interface all -hp- GPIB SOurces to the 3320B remote
input.
2-25. There are three GPIB bus cables available (See Table
2-1). Up to 15 instruments may be connected in parallel
using these cables; however, the following two restrictions
must be observed.
1. When more than two instruments are connected to
the bus, the cable length added for each additional
instrument cannot exceed six feet per unit.
2. The total cable length to all units cannot exceed
51 feet.
The cables are listed with their respective lengths, in Table
2-1. A typical bus system is shown in Figure 2-5.

2-26. The -hp- Model 3260A Marked Card Reader supplies
its own interface cable. If the card reader cable is -hp- Part
No. 03260-61607, an 11235A Adapter must be used to
interface the card reader to the 3320B. If the card reader
cable is -hp- Part No. 0326Q-61605, the 11235A Adapter is
Section 11
not required. However, the following card reader cable
modification must be performed for proper operation.
3260A CABLE (03260-61605) MODIFICATION
(For use with 3320B Option 007)
1. Remove the four Screws holding the cover on the
interface card on the end of the WI Cable.
2. Move the violet wire to pin 8.
3. Move the white wire to pin 18.
4. Move the key from pin
J
to pin T.
5. Replace the screws and covers.
6. The modification is complete.
2-27. The -hp- 9800 series Calculators can be interfaced to
the 3320B using the -hp- 1I144A Interface Card, a
1063IA/B/C GPIB bus cable, and the 11235A Adapter.
2-28. The -hp- Model 2114,2115,2116 or 2100 computers
can be interfaced using the -hp- Model 59310 Interface Kit.
The 59310 kit includes an interface cable, a computer I/O
card, and computer programming instructions.
An
-hp-
11235A Adapter must be used to interface the cable
supplied with the 59310 kit to the 3320B.
