Mechanical & Electrical Installation

The ProLink6 primary signal or secondary signal can be connected to either the Port A
fiber jack or the Port B fiber jack. The PLR automatically detects if either the primary or
secondary signal is connected to each port. Only one primary and secondary ProLink6
signal is allowed per PLR.
After receiving the ProLink6 signal, the PLR generates the ProLink5 or ProLink8 data signal
to send out to the display modules.
Daktronics requires that the PLR ProLink5 SATA port
connects to the designated modules with a
Daktronics-specific crossover SATA cable. Refer to
Figure 12 .
In emergencies, a standard crossover SATA cable will work; however, Daktronics cannot
guarantee the functionality of the standard cable. Using a Daktronics-specific crossover
SATA cable ensures the highest quality signal reception.
Redundancy is not a system requirement. The number of modules and the PLR
configuration varies depending on the installation. Refer to the appropriate
contract-specific Config Drawing and Signal Interconnect Drawing for further
information. Refer to Figure 13 for an example of redundant routing.

PLR615X Mounting
The PLR615X is attached to a metal mounting plate;
this two-piece unit mounts inside the display with
attachment screws. Refer to Figure 14 .
Mount the PLR by hanging the plate at the proper
location in the cabinet and tightening the attachment
screw. The PLR should always be replaced as a full
assembly. To access the PLR, refer to Access the PLR
(p.23) .
