Computer connection

If your encoder is supplied with an USB interface, it will either be connected to the printer’s internal USB Hub, or equipped with a USB cable

to connect to your computer directly.

In the rst case, your printer’s USB cable is used to drive rstly the printer and secondly the encoder from the computer.

If your encoder is supplied with an RS-232 interface, it needs to be connected to the computer via a serial cable. This cable plugs into the

printer’s female DB-9 socket, and into a COM port on the computer.

A sequence of commands must be sent via the printer’s interface to insert a card in the printer then position it close to the antenna to

establish radio communication between the card and the encoder.

The command sequence is as follows:

Sending the SIC sequence:

l A card is moved from the feeder towards the antenna and is positioned nearby.

l The chip is programmed via the computer’s serial (or USB) interface connecting the built-in encoder and the computer.

Refer to the Evolis Programming Guide for further details on programming contactless smartcards.
