Connections

3.5 GPIB Control Connection

On the rear panel of the matrix is a GPIB (IEEE-488) control port which gets

connected to the GPIB port of a computer (controller) using a shielded IEEE-

488 interface cable with metric mounting screws. Figure 3-4 shows the

connector configuration and Table 3-4 shows the signal assignments.

3.5.1 GPIB Control Connector

You can link devices in either a linear, star or combination configuration using a

shielded 24-conductor cable. The standard IEEE-488 cable has both a plug

and receptacle connector on both ends. This connector is the Amphenol

CHAMP or Cinch Series 57 MICRO RIBBON type. See figure 3-4.

The following restrictions apply for normal operation when attaching instruments

to the GPIB:

• A maximum separation of 4 meters between any two instruments and an

average separation of 2 meters over the entire bus.

• A maximum total cable length of 20 meters.

• No more than 15 devices on the bus, with no less than two-thirds

powered on.

• No two instruments having the same address.

If you are unable to meet the above restrictions, the use of bus extenders is

recommended.
