PLR615X Signal Distribution
The ProLink6 control system sends ProLink6 signal through
a dual coax cable to the PLR615X. Refer to Figure 15 .
The PLR615X receives ProLink6 signal and uses it to
generate ProLink5 or ProLink8 signal that is sent out to the
modules.
Contract-specific drawings show the signal path
between PLRs within the display and their respective
ProLink6 master ports.
Figure 16 shows a typical signal routing for a ProLink6 control system with redundant
signal using dual coax connections.
Note: Arrangements vary with section or cabinet size and a ProLink6 controller may
supply signal data to more than one display section.

The ProLink6 primary signal or secondary signal can
be connected to either the Port A coax jack or the
Port B coax jack. Port A consists of coax Channel 0
and Channel 1; Port B consists of coax Channel 2 and
Channel 3. Refer to Figure 17 .
Each port can support a receive/transmit (Rx/Tx) pair but
Rx/Tx pairs cannot cross between ports. This is referred to
as “auto-negotiation rules”.
ProLink6 is capable of determining which channel is receiving and which is transmitting
data on each port. Because of this capability, it is possible to swap a ProLink6 master
cable pair’s transmit and receive on either port if the pair does not cross ports.
