DCT3080 Installation Manual

Diagnostics

This section describes the diagnostics that confirm proper installation,
including:

Checking error states and signal integrity

Identifying the cable terminal on the network

Verify communications with the headend

Diagnostics are displayed on the on-screen display (OSD) and front-panel
LEDs.
For the diagnostics described in this section:

All indicators are in decimal notation, unless otherwise noted.

All signal-level and quality indicators use a 1% to 100% scale, unless
otherwise noted.

All sample displays are illustrative; actual data may differ from the
examples.

You can use the diagnostics when running the base platform or Thin
Client software.

Note:

Diagnostics are continually updated through software upgrades to provide

expanded information regarding the status of the DCT-3080. Check the

Motorola website for updated versions of this manual (www.motorola.com).

Using the Diagnostics

To use the diagnostics:

Ensure that the DCT3080 is installed with the base platform or
Thin Client software and that it is connected to an AC outlet.
