(RJ45)
The D12 is fitted with a 2-wire serial remote control interface, (2 x RJ 45)
carrying both the RIB and CAN-Bus signals. All pins of both connectors
are wired in parallel allowing either to be used as the input or output.
Where remote control networking conforms to a "Bus or Ring topology"
one connector is used for the incoming signal and the second connector
allows for direct connection to another device (daisy chaining) or for
terminating in the case of a CAN-Bus network. The interface connections
for the RIB (pin 7/8) are opto-coupled, while the connections for the
CAN-Bus (pin 4/5) are hard wired to common ground (protective earth).

IMPORTANT!
Regarding the CAN-Bus network shielded cables and
shielded RJ45 connectors must be used while the cable
shielding must be connected to both sides of the RJ45
connector as the "CAN Ground" is routed via the cable
shielding.
Note:
A detailed description of remote control via dbCAN (CAN-Bus) is given
in the technical information TI-312 (d&b code D5312.E.).
A detailed description of remote control via RIB is given in the technical
information TI-310 (d&b code D5310.E.).
5.1.4. SERVICE [11]
Fig. 10: SERVICE connector (D-SUB-9)
The D-SUB-9 SERVICE interface (RS 232 female) allows operating
software and loudspeaker configuration updates to be loaded into the
unit.
IMPORTANT!
To connect the computer to the SERVICE connector a
standard RS-232 connection cacble (D-SUB-9 serial cable
female/male - 1:1) must be used (serial extension cable).
