Chapter 3 Connecting The Apm - AUDAC APM Bedienungsanleitung

Chapter 3
Connecting the APM
The APM's should be connected to the Matrix system or Relay units by means of Twisted pair
CAT6 cabling. The maximum distance from the beginning of the bus to the last device is limited to
a total cable length of 300 meters.
The supply voltage will be delivered to the APM over the twisted pair cable, and the voltage level
on the APM side should be at least 16 Volts. When the voltage level on the APM side is lower
than 16 Volts, the system won't work properly, and an ARJ03P junction box with external power
supply need to be applied.
- Up to 9 APM units can be placed on the same bus, with a total maximum bus cable length
of 300 meter using ARJ03P modules. (This 300 meters includes the cable distances from the
ARJ03P junction boxes to the APM's)
- A maximum of two APM units can be placed on one APM bus, without external power supply
- When using more than two APM units on one APM bus, an external power supply should be
applied.
