>>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 first case, your printer’s USB cable is used to drive firstly 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.
