Status Indicators
Testing and Troubleshooting
Enhanced Gateway Board will have the following indicator characteristics when operating
properly:
• +5 VDC LED on solid (CR8).
• Blinking CPU LED (CR6). A dimly lit LED can also indicate proper operation because
the blink rate becomes so fast that the LED appears dimmer than the +5 VDC LED (CR8).
• Rapidly Blinking CRIND A and B LEDs. Side A is CR4 (TX), CR5 (RX), Side B is CR9
(TX). These LEDs indicate good communication with the CRIND. They mimic the LEDs
on the T17764 series of CRIND Boards. The Encore 500 Series CRIND node has two
TRIND LEDs, D12 and D13, present in board under the TRIND connector.
