Plr615X Self-Test Mode - Daktronics PROLINK ROUTER 605 Series Installation And Maintenance Manual

PLR615X Self-Test Mode

The PLR self-test mode is used to test internal systems and I/O ports. While in self-test
mode, the PLR tests for correct operation and shows a pass/fail status on the four status
LEDs as described in PLR615X Status LEDs (p.31).
If any failures are detected, error codes are displayed to define the source of the failure.
The self-test connections are shown in Figure 33.

To put the PLR615X into self-test mode, follow these steps:
1. Loop the SATA cable from Port A to Port B on the ProLink5 jacks.
2. Connect a coax cable from coax Channel 0 to coax Channel 3 and a second cable
from coax Channel 1 to coax Channel 2.
3. Disconnect the power and then reconnect the power.
During the self-test, the HB LED toggles once per second. The four status LEDs light up for
three seconds before initiating a repeating test-in-progress pattern. This alternating chase
pattern may take up to 60 seconds to run. Refer to Figure 34.
