• MODBUS connection diagram

These diagrams are valid for

AHU-xMxSx1

models only.

The RS485-MODBUS line has a long main bus to which the appliances are connected directly (max 32 appliances).

Use cables with a braided pair + 1 ground wire + shield.

Use the braided pair to connect

A+

and

B-

and the single wire for

GND

which must be connected to each device.

Connect the shield to ground at a single point, preferably near the master.

The cable must be of type MODBUS RS485 data transmission.

The ends of the cable must be connected with a 120 ohm termination resistance.

To fit the 120 ohm to the regulator, see

“40. Jumper configuration” page 136

.

The maximum length of the bus depends on the baud rate and the cable itself.

For a baud rate of 9600, the cable (AVG26 type) can be up to 1000 m long.

Any branch lines must be short, at most 20 m long. If you use a multi-port tap for n branches, each branch can be up to 40 m

divided by n.

To increase the number of devices on the line or increase the length of the cables, you must install a signal repeater.

Add a signal repeater for every group of 32 appliances connected.
