SUMMARY

The following information discusses tools and procedures available for diagnosing and troubleshooting problems with the Digiboard C/CON 16 while the device is operational.

The C/CON 16 control panel (located in the front of the device) contains 10 LED indicators, a 2 digit LED display, and two buttons that are useful in diagnosing and monitoring problems and functions of the concentrator.

The following is a visual description of the Digiboard C/CON 16 control panel:

MORE INFORMATION

The push buttons at the right of the control panel are used to access twenty display modes, by pushing the left or right arrow buttons.

The table below describes these modes in detail.

When AC (activity) is shown on the 2 digit LED, the ten LEDs flash from left to right. The speed of this strobing effect indicates the overall activity of the device.

1-16 shows the channels from 1 through 16. Under these modes, the LEDs act the same as a line monitor.

NOTE: If the push buttons are pressed simultaneously, software flow control is turned off.

PC displays the Packet Count on the LEDs as a binary count of total packet count that are received or transmitted. The low byte is the left most LED (TD).

EC displays the Error Count (total errors) in binary. Pressing both push buttons at once resets the count to zero.

PU describes the Process Utilization. The LEDs are used as a bar graph showing the concentrator's processor time in percentage. From the left, each LED increments the PU by 10 percent.

LU describes the Line Utilization. The LEDs are used as a bar graph showing the concentrator's processor time in percentage. From the left, each LED increments the PU by 10 percent.

1n, 2n, 3n, 4n, 5n, 6n, 7n, and 8n show the node number of the concentrator. The LEDs function just as they do in AC mode.
