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 (

) 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
