*Not all ProLink5 nodes support this pattern yet. If a node does not support it, the previous
test pattern will continue to display during this frame. The following minimum firmware
versions are required for this test pattern:
• ProLink 5.2/5.3 Modules: User Micro Revision 0x1051
• PLC51XX: User Micro Revision 0x1050
• MLC51XX: User Micro Revision 0x1053
•
Display firmware package: dispfw_2016.12.5-c185743f
**These patterns are useful to detect breaks in a chain or ProLink5 nodes if there is only
one PLR driving that chain.
If a receiving PLR stops receiving frame commands, it stops sending test pattern
commands to the ProLink5 nodes. The test patterns are sent with an approximately
20-second timeout; the ProLink5 nodes will blank after approximately 20 seconds if a
transmitting PLR is disconnected from ProLink6 or the receiving PLR is disconnected from
its ProLink5 nodes.
To exit the ProLink6 test pattern mode, follow these directions:
• Transmitting PLR: disconnect the SATA loopback, disconnect and reconnect power.
• Receiving PLR: disconnect the transmitting PLR, reconnect to a ProLink6 controller.
