2.9 General Operation
Refer to the following sections for specific operational modes. This sub-section
gives a general test of functionality. After setting the power on defaults and
reassembling the Serial488A, plug the power supply connector into the rear jack on
the interface.
CAUTION
Never install the power supply into the interface
while it is connected to AC line power. Failure
to observe this caution may result in damage to
the Serial488A.
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 AC line power. Place the rear panel power switch in the ON [1] position.
All the front panel indicators should light momentarily while the Serial488A performs
an internal ROM and RAM self check. At the end of this self check all indicators
except POWER should turn off.
If there is an error in the ROM checksum, all of the LEDs will remain on.
Flashing LEDs indicates a RAM failure. Should such an error occur, turn the rear
panel switch to the OFF [0] position and retry the above procedure.
When the Serial488/512K is first powered on, it performs a self test which lasts
approximately 15 seconds. The front panel LED's will flash while the self test is
performed. If the unit is functional, all LED's except power should turn off after the
self test is completed. If one or more LED's remains flashing, refer to the Hardware
Fault Identification Table to determine the cause of error.
