2.3.3.6 Service (Pin 45)
The Service input is an edge sensitive input capable of generating a
Service Request (SRQ). It is enabled with the SRQ command (M1) and
defaults to rising-edge sensitive. The Invert command (I64) can be used to
program it to be falling-edge sensitive.
2.4 INSTALLATION
To begin operating the Digital232, 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 Digital232.
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
Digital232 by depressing the rear panel power switch. All the front panel LEDs
should light for approximately one second while the Digital232 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 Digital232 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
Digital232 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
