Chapter 2 Program Instructions

LED ON/OFF

Field of Application

Statement for turning a speciﬁ ed LED control lamp on or off.

Syntax LED<nexp>ON | OFF

<nexp> is the LED which is to be turned on or off.

0 is the “Ready” LED.

1 is the “Error” LED.

Remarks

All present Intermec Fingerprint printers are equipped with three LED (Light

Emitting Diode) control lamps on the front panel. Two of the LEDs can be

used to indicate for example when an error occurs or when the printer is ready.

It is up to the programmer to decide how they will be used, but since the LEDs

are marked with text, some restriction is recommended.

The “Power” LED is connected to the On/Off switch and cannot be

controlled by the program.

Example

In this example, the “error” LED will be lighted if you, for example,

attempt to run the program with a raised printhead. Lower the printhead

and a label will be fed out. The “error” LED goes out and the “ready”

LED comes on.
