WARNING
The power supply provided with the interface is intended for
INDOOR USE ONLY. Failure to observe this warning could
result in equipment failure, personal injury or death.
After installing the power supply connector into the interface, plug the power
supply into the AC line power. Place the rear panel power switch in the ON [1] position.
All front panel indicators should light for approximately one second while the Parallel488
performs an internal ROM and RAM self check. At the end of this self check all
indicators except POWER should turn off. If any of the following LED conditions exist
after power-on, a failure has occurred.
SYMPTOM FAILURE
All lights remain on ROM test has failed
All lights blink continually RAM test has failed
An LED does not blink LED has failed
No LEDs blink Power supply has failed
If any of the above symptons occur, cycle the power switch on the Parallel488 to
be sure of the problem. If the problem is unresolved, refer to the Service Information
section of this manual.
If proper operation is obtained, turn-off the Parallel488 power switch, and connect
a parallel interface cable to the rear of the Parallel488. Connect the other end of the cable
to the device having the parallel interface. Now connect the IEEE cable to the rear of the
Parallel488, and the other end to the IEEE device.
Now apply power to both the IEEE device and the parallel device. The Parallel488
is now ready to perform the data transfer between both devices.
WARNING The Parallel488 makes its earth ground
connection through the
parallel interface cable. The unit
should only be connected to an IEEE bus device after first
being connected to the parallel device. Failure to do so may
allow the Parallel488 to float to a voltage away from ground.
This could result in damage to the interface, personal injury or
death.
