Fig. 3.3: Labelling of serial interface terminals

The SCC ports of the router are DCE type devices. Based on standards the receiver terminal RxD of

the connected DTE device is connected to the transmitting terminal of the router's SCC port which is

also labelled RxD. Similarly the red LED indicating transmission from SCC is labelled RxD.

3.3. Ethernet

• Connector RJ-45 for Ethernet 10BaseT and 100BaseT corresponds to the EIA TIA T568B standard.

• Informative LED diodes indicate:

○ Tx – yellow - output or input active (*Tx - red - output from ETH channel)

○ Rx – yellow - output or input active (*Rx - green - input to ETH channel

Note

Green LED Tx and yellow LED Rx flash simultaneuosly. The informations marked

(*) are valid for hw version produced until 07/2008.

○ 100 – yellow - if lit the 100Base-TX net is indicated otherwise is 10Base-T

○ LINK – green - indicates correctly connected link

○ F.D. – green - indicates full duplex operation

• The direct cable serves for connecting to the Ethernet network via the hub (repeater) or switch-hub

(router).

• A crossed cable serves for connecting only two devices - MR400-MC100, MR400-PC, etc.

The ETH module consumption is 30 mA (60 mA until 07/2008).

The following table contains connector connections and colours of conductors. For the crossed cable

the order of conductors on one side is the same as for the direct cable.
