PLR605X ProLink6 Display Test Patterns
The ProLink6 test pattern mode is used to light up a display for troubleshooting purposes
or in cases when a ProLink6 controller, such as a VIP-5X6X, is not yet installed on site. It
consists of a single PLR605X (transmitting PLR) sending frame commands to the other PLRs
(receiving PLRs) in the ProLink6 signal chain.
When the receiving PLRs receive a frame command, they render the associated test
pattern on the display by transmitting test pattern commands to the ProLink5 nodes.
Refer to the following table for the test pattern frame sequence.
Before starting the test pattern mode, ensure that the PLR605X has the following minimum
firmware versions:
• User Micro Revision 0x1050
• User EPLD Revision 0x1052
To put a PLR into transmit mode, loop a SATA cable from
Port A to Port B on the ProLink5 ports, disconnect power,
and reconnect power. The transmitting PLR shows
t 6 t on the 7-segment display to indicate it is transmitting
ProLink6 frame commands. Refer to Figure 27 .
To put a PLR into receive mode, first disconnect any
ProLink6 controllers and connect the transmitting PLR to
the ProLink6 chain. All PLRs in the ProLink6 chain should
enter receive mode within five seconds and begin
displaying test pattern commands. The receiving PLRs
show t 6 r on the 7-segment display to indicate they are
receiving ProLink6 frame commands. Refer to Figure 28 .
Note: The frame commands are not perfectly synchronous among PLRs. It is normal for
PLRs to change test patterns slightly out of sync, but each PLR should update to
a new frame within 1 second. If a receiving PLR takes longer than 1 second to
switch to a new test pattern (compared to nearby PLRs), it indicates a problem
with that PLR, ProLink6 signal to that PLR, or ProLink5 communication to that
PLR’s ProLink5 modules.
The test pattern frame sequence is listed in the following table. Each frame is held for
approximately 10 seconds. The sequence will repeat as long as the transmitting PLR is
powered on and connected to the receiving PLRs.
