>>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:
• A card is moved from the feeder towards the antenna and is positioned nearby.
• The chip is programmed via the computer’s serial (or USB) interface connecting the built-in encoder and the computer.
