MINI RECEIVER WITH FIELD BUS
USER MANUAL
3-1
3. CONNECTION
There are two possibilities for connecting the bus. The first one uses the standard wiring model
through the internal terminal strip, in which case the TUNNER receiver equipment is maintained in the
sealed condition and must be carried out as described in the following section "Internal Connection"
for intercommunication with the bus.
As a second option, you can use a TUNNER box that incorporates a female DB9 connector or an
RJ45 connector on the base of the housing. The "External Connection" section describes how to
connect to the BUS. In this case, having a non-leak proof opening, the safety condition against
humidity is lost for outdoor use and therefore its use is limited to an indoor installation.
3.1 INTERNAL CONNECTOR
When using the terminal block to connect the BUS, we will use the following diagrams according to
the type of bus available. Keep in mind that the bus cable must be separated from the power cable of
the equipment.
