The AlphaCom E exchanges has two serial ports. In AlphaCom E20 and E26 they are available on RJ45 connectors. In AlphaCom E7 the serial port 0 is on a 9 pin DSUB connector, and the 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.
Pinout of the RJ45 connector:
| 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+ |
