9.4 Data Interface
The data interface is a serial interface according to RS 422 standard (CCITT/X27 resp.
DIN 66259, part 3). The receiving lines are terminated in a 68 Ohm impedance to
ground.
The interface parameters are the following:
Transmission: asynchronous, full duplex
Transfer rate: 9600 Baud
Character length: 8 bit
Frame: 1 start bit, 1 stop bit, parity even
Handshake: software handshake XON/XOFF
The XOFF signal is sent by the controller as soon as the receiving buffer is almost full.
The receiving buffer has a total depth of 20 bytes.
