2.5 Installation
To begin operating the Digital488, plug the external power supply 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
Digital488.
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, turn on the
Digital488 by depressing the rear panel power switch. All the front panel LEDs should
light for approximately one second while the Digital488 performs an internal ROM
and RAM self check. At the end of this self check all indicators should turn off except
POWER.
If you obtain the above response then your Digital488 is alive and well. If all
LEDs remain on, then a ROM error has occurred. If all LEDs continue to flash (except
the power LED), then a RAM error has occurred. Try cycling the power to the
Digital488 to determine that the error is repeatable.
If the LEDs do not flash and the POWER indicator does not remain lit, there
may not be any power supplied to the interface. In this event, check to make sure the
AC power is supplied to the power supply, and that the supply is properly installed into
the unit. If the problem is unresolved, refer to the Service Information section of this
manual.
