IOtech Digital488, Manual

Page: 20 / 64

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
Do not use this interface outdoors. The interface is intended for indoor use only.
Outdoor conditions could result in equipment failure, bodily 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.
