The AlphaCom XE exchanges has two serial ports. In AlphaCom XE20 and XE26 they are available on RJ45 connectors. In AlphaCom XE7 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.

AlphaCom - RIO cabling

Cabling between the RIO unit and AlphaCom XE using multidrop RS485:

 AlphaCom               RIO #1                  RIO #n           
 Serial port          15 pin DSUB             15 pin DSUB
  RJ45

   1 -------------------------+-- 2 --+----------------+-- 2
                              |       |                |
                              --- 4 ---                --- 4

                              |       |                |
                              --- 11---                --- 11

   5 ---Gnd (optional)--------+-- 5 --+----------------+-- 5

In the 15 pin DSUB of the RIO unit pin 2 & 4 and 9 & 11 must be connected together.

The GND connection between AlphaCom and RIO in RS485 mode is normally not necessary. In general on RS485 links, the connection of a third wire (GND) between the source and receiver may be done to limit the common mode voltage that can be impressed on the receiver inputs.

Note that when using RS485, the switch S601-8 on the AMC-IP must be set to RS422 positon, and two jumpers must be moved from RS422 to RS485 position. These jumpers are located on the AMC-IP filter board for XE20 and 26, and on the backplane of the AlphaCom XE7. On the AlphaCom XE1 you need to open the cover to access the jumpers.

Cabling between the RIO unit and AlphaCom XE using point to point RS232:

 AlphaCom                   RIO                             
 Serial port             9 pin DSUB
