 
The PLR automatically detects if the signal is either the
primary or secondary signal and which channels are
designated Rx/Tx on each port. However, only one primary and one secondary ProLink6
signal is allowed per PLR.
After receiving the ProLink6 signal, the PLR generates a 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 20 .
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 of signal reception.
Redundancy is not a system requirement. The number of modules and the selected
configuration varies depending on the installation. Refer to the appropriate contract-
specific Config Drawing and Signal Interconnect Drawing for further information. Refer to
Figure 21 for an example of redundant routing.
