1.1.6 Fiber SFP Type LC (Interconnect)
The communication of fiber devices is performed via Gigabit SFPs that have to be connected to suitable fibers fitted with type LC
connectors (see Chapter 1.2.2).
NOTE: The correct function of the device can only be guaranteed with SFPs provided by Black Box.
CAUTION: SFP modules can be damaged by electrostatic discharge (ESD).
When handling, take care not to damage devices.
1.1.7 Serial Interface
The serial interface option supports a full-duplex transmission with a real hardware handshake up to a baud rate of 19,200.
The CON Unit is cabled as DTE (Data Terminal Equipment, such as CPU output) and can be connected directly to DCE (Data
Communication Equipment) devices.
• 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 (cross-over cable)
between the CON Unit and the device.
Operation of several devices:
The serial interface transmits six signals (three for each direction). Normally, four of the six signals are handshake signals (in
addition to RxD and TxD). The following configurations, however, are possible 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 the printer and PC.

1.1.8 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 CON Unit.
