Connecting Your Hardware
Step 2. Connect the Cables
To connect the cables to both GPIB extenders, complete the following steps:
1.
Make sure that each GPIB extender is powered off.
2.
Connect the two connectors on each end of the fiber-optic cable to your GPIB extenders, as
follows:
a.
As shown in Figure 2-2, align the connector marked T (transmit) with the connector
marked TRANS on the side panel of the GPIB extender. Align the connector marked
R (receive) with the connector marked RCVR on the side panel of the GPIB extender.

b.
Remove the caps on the connectors.
c.
Align the notch on each cable connector to the slot of the fiber-optic connector on the
box.
d.
Firmly push in the cable connector and rotate the sleeve clockwise until it locks on to
the side notch of the fiber-optic connector on the box.
3.
Connect the end of the extender with the GPIB connector to your GPIB system. Make sure
that you follow all IEEE 488 cabling restrictions. For typical restrictions, refer to the
Configuration Requirements
section in Appendix A,
GPIB Basics
.
4.
Plug the utility power cord included with your GPIB extender into an AC outlet of the
correct voltage.
5.
Plug the other end of the utility power cord into your GPIB extender.
Step 3. Switch On Your GPIB Extender
Power on each GPIB extender. The POWER LED should light immediately. If the POWER
LED does not light immediately, make sure that power is supplied to your GPIB extender.
The LINK LED lights only when both GPIB extenders are on and the fiber-optic cable is
properly connected between them.
