Operation and communication

5.1

Communication via the RS-485 Interface

The controller and read head communicate via the RS-485 interface during operation. Make

sure that the basic communication settings have been made on the read head, such as setting

the read head address and baud rate.
A distinction is made between request telegrams that the controller sends to the read head and

response telegrams that the read head sends to the controller. Each byte of a request or

response telegram consists of 9 bits (8 data bits + 1 parity bit).

5.1.1

Request Telegram

A request telegram always consists of 2 bytes. The second byte corresponds to the first byte,

but with the 8 data bits of the first byte inverted.
