In the AlphaCom E20 and E26 exchanges the two serial ports are available on RJ45 connectors. In the AlphaCom E7 serial port 0 is 9 pin DSUB, and serial port 1 is on a RJ45 connector.

The serial port 0 is RS232 only, the serial port 1 can be RS232, RS422 or RS485.

The pinout on the RJ45 connector is as follows:

RJ45 pinout
RS232 3 = TX<br\>6 = RX<br\> 4&5 = GND
RS422 1 = RX-<br\>2 = RX+<br\>7 = TX-<br\>8 = TX+
RS485 1/7 = Data - <br\> 2/8 = Data+

<br\><br\>

Adaptor cable from RJ-45 to 9-pin Female D-SUB:

RJ45 - AlphaCom E 9 p Female DSUB
3 2
5 5
6 3


Cabling between RIO unit and AlphaCom E using multidrop RS485:

RJ45 - AlphaCom E RIO 15 p DSUB
1 (RX-) 9 (TX+)
2 (RX+) 2 (TX-)
7 (TX-) 11 (RX+)
8 (TX+) 4 (RX-)
