1.6 INTERFACES

10/100 MBit/s connection (TP port)

The 10/100 Mbit ports of the RS2-xTX/xFX

EEC (8-pin shielded R45 sockets),- three ports on the RS2-3TX/2FX…- four ports on the RS2-4TX/1FX…

allow DTEs or independent network seg

ments complying with the standards IEEE

802.3 100BASE-TX / 10BASE-T to be

connected. These ports support autonego

tiation, the autopolarity function and

autocrossing.

The socket casings are electrically connec

ted to the front panel of the RS2-xTX/xFX

EEC.

Pin configuration of the RJ45 socket,

RS2-xTX/xFX EEC:– 1 line pair: pin 3 and pin 6– 1 line pair: pin 1 and pin 2– remaining

100 Mbit/s connection (FX port)

The 100 MBit/s ports of the

RS2-xTX/xFX EEC,- one port on the RS2-4TX/1FX…- two ports on the RS2-3TX/2FX… support

the IEEE 802.3 100BASE-FX FDX standard.

They use a duplex SC connector or a ST

connector (on RS2-4TX/1FX-ST EEC). Each

100 MBit/s port allows one further DTE or

an optical network component to be

connected.

5pin terminal block

The supply voltage and the indicator

contact are connected via a 5pin terminal

block. If the terminal block is fitted the

wrong way round, the device will still work

correctly.

Voltage supply: Redundant voltage sup

plies are supported. Both inputs are

decoupled. There is no load distribution.

With redundant supply, the power pack

supplies the RS2-xTX/xFX EEC only with

the higher output voltage. The  supply vol

tage is electrically isolated from the hou

sing
