In the AlphaCom E20 and E26 the two serial ports are available on RJ45 connectors. In the AlphaCom E7 serial port 0 is 9 pin DSUB, and serial poret 1 is RJ45.
The serial port 0 can be RS232 only, the serial port 1 can be RS232, RS422 or RS485.
The pinout on the RJ45 connector is as follows:
| AlphaCom E | |
|---|---|
| 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+ |

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