7 Specifications
7.1 Interfaces
7.1.1 RJ45 (Interconnect)
The communication of the 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.
7.1.2 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 connectors type LC (see
Chapter 7.2.2, Page 144).
The correct function of the device can only be guaranteed with SFPs
provided by the manufacturer.
SFP modules can be damaged by electrostatic discharge (ESD).
When handling, care must be taken so that the devices are not damaged.
7.1.3 RJ45 (Network)
The communication of the Cat X devices requires a 1000BASE-T
connection.
The cabling has to be done according to EIA/TIA-568-B (1000BASE-T)
with RJ45 connectors at both ends. All of the four wire pairs are used in
both directions. The cabling is suitable for a full duplex operation. For the
cable connection to a source (computer, CPU), a crossed network cable
(cross cable) has to be used.
7.1.4 RS-232 (Serial)
The communication takes place with a transmission speed of up to
115.2 KBaud, regardless of the file format. The transmission takes place
with eight data bits and a stop bit, but without a parity bit. Limited
hardware handshake (DSR) is possible.
