2.6 Operation
After configuring the Extender488/HS IEEE 488 Bus Extenders and connecting the
Extender488/HS cable, plug the power cable connector into the rear jack on the bus extender.
WARNING
The Extender488/HS Bus Extender is intended for INDOOR USE ONLY. Failure
to observe this warning could result in equipment failure, personal injury or death.
The Extender488/HS Bus Extender makes its earth ground connection through the
IEEE interface cable. Each bus extender must be connected to at least one IEEE
device which is earth ground referred. Failure to do so may allow the
Extender488/HS Bus Extender to float to a voltage away from ground. This could
result in damage to the Extender488/HS Bus Extender, personal injury, or death.
CAUTION
Make sure that the Extender488/HS Bus Extender that is connected to the controller
is set for Local Extender mode and the other Extender488/HS Bus Extender is set to
Remote Extender mode before applying power. Failure to observe this caution will
result in damage to both Extender488/HS Bus Extenders
After installing the power cable into the bus extender, plug the power cable into the AC line power.
Place the rear panel power switches on both units in the ON [depressed] position. The CONNECT and
POWER LEDs should light on both units. The REMOTE EXTENDER LED should be lit on the unit set
for REMOTE EXTENDER operation and the LOCAL EXTENDER LED should be lit on the unit set for
LOCAL EXTENDER operation. If the LOCAL unit is connected to an IEEE 488 controller and the
controller is on, the LISTEN LED should be lit on the LOCAL unit and the TALK LED should be lit on
the REMOTE unit. If any of the following LED conditions exist after power-on, a failure has occurred:
