9.1.7 GPIO
An external switching solution (dry contact) with up to four buttons, each of which one associated LED can
be connected to this interface. After pressing a button, the corresponding source is switched. The switching
carried out is indicated on the associated LED. E.g., button 1 is assigned to the USB-B port for source 1.
Max. 50 mA is supplied at the port for the power supply.
9.1.8 RJ45 (Interconnect)
Communication between Cat X devices requires a 1000BASE-T connection.
Connector wiring must comply with EIA/TIA-568-B (1000BASE-T), with RJ45 connectors at both ends. All
four cable wire pairs are used.
9.1.9 Fiber SFP Type LC (Interconnect)
Communication of fiber devices is performed via Gigabit SFPs that are connected to suitable fibers fitted
with connectors type LC (see chapter 9.2.2, page 100).
NOTICE
The correct function of the device can only be guaranteed with SFPs provided by the manufacturer.
NOTICE
SFP modules can be damaged by electrostatic discharge (ESD).
Please consider ESD handling specifications.
9.1.10 RS232 Serial
Extender modules with serial interface option support a
full-duplex transmission
with a real hardware
handshake up to a baud rate of 115,200 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 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.
