7.1.1 Serial Interface
The serial interface option supports a full-duplex transmission with a real
hardware handshake up to a Baud rate of 19,200 Baud.
The CON Unit is cabled as DTE (Data Terminal Equipment, like CPU
output) and can be connected directly to DCE devices (Data
Communication Equipment).
 A touch screen can be connected directly to the CON Unit.
 To connect to a serial printer (or any other DTE instead of DCE
device), you need a null modem cable (crossed cable) between CON
Unit and the device.
Operation of several devices:
The serial interface transmits 6 signals (3 for each direction). Normally,
4 of the 6 signals are handshake signals (in addition to RxD and TxD).
The following configurations, however, can be realized using special
adapter splitting cables:
 Three single 2-wire transmissions
 Two transmissions with a handshake signal
 A serial mouse and a single 2-wire transmission.
In this case, choose X-ON / X-OFF software handshake for traffic control
at printer and PC.
