Use an RS-485 signal distributor to increase the maximum number of devices on

the bus as well as the total range. Each distributor output provides another RS-

485 bus, extending the output an additional 1200 m. Up to 31 NVRs can be

connected to each output. See Figure 4 below.

4. See section “RS-485 ports” on page 8

Caution: Most signal distributors are unidirectional. This means that the signal

only flows from the input towards the outputs. Consequently it is not possible to

connect several keypads.

See section “RS-485 ports” below to configure the RS-485 port communication

settings.
