System Displays

Five LEDs are included on the SV Series back panel.

Power/Sync LED

This LED is illuminated green whenever power is applied to the SV Series. Upon receipt of any sync input (hardware or serial communications), the LED blinks yellow for approximately 100 milliseconds.

Calibration LED

This yellow LED indicates calibration status. Please refer to "Calibration" on page 5-8for details.

Read LED

This green LED is illuminated whenever a bar code is being fully decoded.

Indicator LEDs 1 and 2

The two green indicator LEDs are user programmable exactly like the five output ports. Their functions are intended for use as indicators for specific analysis results.

A common example is programming LED 1 to illuminate in latch mode whenever a symbol quality error is detected, while programming LED 2 to illuminate in latch mode whenever a No Read error is detected.
