ProLink Router
The ProLink router (PLR) is a circuit board that passes display data from the
ProLink6 control system modules and other PLRs.
Figure 27 illustrates a PLR. Refer to the DD1735784 ProLink Router 6X5X
Installation & Maintenance Manual in Appendix B for further information.
For information on removing a PLR, refer to Section 4.3 .
Power Supply
Figure 28 illustrates a typical power supply, also referred to as a power module. The
power harnesses connected to the unit vary depending on type and overall display
application. The power LED (DS1) illuminates when the unit is receiving
incoming power.
Caution: Disconnect display power before servicing the power supplies to avoid
electrical shock. The power supplies run on high voltage and may cause physical injury
if touched.
The power supplies are either mounted to the component mounting sheet or to the rear
surface of the module mounting sheet.
If a power supply fails, refer to Section 5.2 for details on the repair process.
