ORION XTENDER INSTALLATION AND OPERATIONS MANUAL 46
 A touch screen can be connected directly to the Receiver 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
.
Analog Audio Interface
The analog audio option supports a bidirectional
stereo audio transmission, in nearly CD quality .
The audio interface is a 'line level' interface and it is designed to transmit the signals of a sound card (or
another 'line level' device) as well as to allow the connection of active speakers to the Receiver unit. Stereo
audio can be transmitted bidirectionally at the same time.
Connection of a microphone:
Connect the microphone to the 'audio' input of the Receiver unit. There are two ways to establish this
connection:
 The output of the CPU Unit is connected with the microphone input of the sound card (red). Adjust the sound
card to provide an additional amplification (20 dB).
