Configuration Guide (AADvance Controller)

Connect Multiple Slave Devices, Full Duplex

You can use a full duplex serial connection to connect multiple Modbus slave devices

to the AADvance controller. To make the physical connection, do the following:

1) Select a suitable cable. We recommend 3-pair, overall shielded cable.

2) Remove the serial port connector from the 9100 processor base unit.

3) Make the connections shown in the illustration. Terminate the twisted pairs with a

120 resistor in series with a 68nF capacitor at the locations shown.

4) Connect the signal ground (not illustrated) from the 0V terminal to each slave

device.

Note: Do not connect the signal ground to the AC safety ground.

5) Insert the connector into the 9100 processor base unit.
