Peripheral interfaces
The R2 offers the possibility to connect many additional input and control units in addition
to the standard direct line inputs.
To connect those additional units, peripheral interface ports are provided on the rear side
of the R2. In the further explanations of this user manual, we will refer to the peripheral
interface ports (RS485) with the letters “PI”, followed by a number ranging from 1 to 10,
each representing one PI port on the rear side of the R2. As this already suggests, there
are 10 PI ports available on the rear side of the R2, each of them performed with an RJ45
connector. 8 of these PI ports are capable of transporting bidirectional audio and data
(ports PI 1-8), while the remaining two ports are only capable of transporting data (ports
PI 9-10).
Devices possible to connect to the PI ports:
DW3020/4020 Basic wall panel with routing and volume control
Multiple DW3020/4020 wall panels can be connected in a bus structure. This wall panel
is only using digital data transfer and no audio transfer, so it can be connected to all
peripheral interface ports from PI1 to PI10. The assignment of the wall panel with a zone
should be done in the user interface.
DW5066 Advanced wall panel with graphic display stereo line input and
microphone input
This wall panel can control multiple zones and has a direct digital audio link to the R2.
Only one DW5066 wall panel can be connected on one PI port, and only PI1 to PI8 can be
used for connecting DW5066 wall panels.
APM Paging system
The APM paging system can be used to page to different paging zones of the R2. Paging
to zones on other R2’s is also possible when multiple R2’s are linked with each-other
through the (optional) fiber interface OPT2.
APM paging consoles can only be connected to PI ports PI1 to PI8. Multiple APM paging
consoles can be connected to one PI port, using a bus structure with ARJ03P junction
boxes. When multiple APM paging consoles are connected to one PI port, only one APM
console can announce messages at a time, so the paging is priority based. Paging with
different APM consoles in different zones is possible when the APM’s are connected to
separate PI inputs.
