Indicator-PC connection

The indicator has a port to connect the device to a PC.

The following photos show where the port is located on the

different models.

The connection requires a special accessory cable (code

F060800), which acts as a USB-serial interface/converter

and communicates as a Virtual COM Port with a USB port

on the computer.

Attention! To use this interface you have to install

the VCP driver, downloadable from:

www.gefran.com/en/products/261-gf_express

When the indicator is connected to the PC you can confi-

gure it without applying power.

The instrument configuration memory is powered by the

USB connection.

Connecting the indicator to the primary power supply while

the USB cable is still connected DOES NOT activate normal

Power-on. You must first disconnect the indicator from the

PC and then apply primary power.

Note: Leaving the USB connected to the PC while the in-

dicator is booting up with cause the unit to fail to boot. The

cable must be disconnected when powering on the unit.
