2-2 MTM400 MPEG Transport Stream Monitor User Manual

Local Indicators

The MTM400 is an MPEG monitor for use in remote situations and does not have

a local graphical user interface display. However, a local interface, consisting of

four front-panel LEDs, can assure you that the MTM400 unit is functioning.

MPEG Transport Stream Monitor

Figure 2-1: Front panel

These LEDs indicate the following:

SYNC Indicates that a valid MPEG transport stream is connected to the

unit.

STATUS Indicates the combined state of the tests currently being performed

on the stream. The test reported by the STATUS LED corresponds

to the Any Stream Error in the RUI (see Device Status, page 3-2).

ETHERNET Indicates the state of the Ethernet physical link.

SYSTEM State of all non-stream items (hardware, time sources). The test

reported by the SYSTEM LED corresponds to the Any Box Error

in the RUI (see Device Status, page 3-2).

Each LED can show one of three colors:

 Green indicates that the monitor is currently passing the test.

 Red indicates that the monitor is currently failing the test.

 Yellow indicates that the monitor is currently passing the test, but has failed

since the last system reset.

The Ethernet LED never shows yellow.
