Extron Electronics DMP 128 User Guide - Manual (Page 15)

usB configuration Port (Front Panel)
A front panel configuration port uses an Extron USB A Male to USB Mini B Male
Configuration Cable,
26-654-06 for connection to a PC computer USB port.
The USB 2.0 port uses a mini type-B connector to connect to a host computer for
control. The DMP 128 USB driver must be installed prior to using the port (see
Installing
the USB Driver on page 15).
notE: The DMP 128 appears as a USB peripheral with bi-directional
communication. The USB connection is used for software operation (see
Windows-based Program Control on page 13), and SIS control (see SIS
Programming and Control on page 129).

a Power LED — The power indicator blinks during power-up and firmware uploads,
and lights solid when the DMP 128 is operational.
b Activity Indicators — Two green LEDs labeled EXP ( Ç ) for the expansion audio port
and LAN ( É ) for the standard Ethernet port
Ç (non-AT models)
Off — The unit is not connected to a second DMP 128.
On — The unit is connected to another DMP 128 and configured as the primary
unit.
Blinking — The unit is connected to another DMP 128 and is currently
configured as the secondary unit.
Ç
(AT models)
Off — Dante device is not responding.
On — The EXP port is connected to a non-AT DMP 128 and configured as the
primary unit.
Blinking — The EXP port is not connected.
É
Indicates activity on the corresponding rear panel Ethernet port connection.
c Input Indicators — Stacked red (signal clipping) and green (signal present) LEDs for
inputs 1 through 12 . Each stack represents one input channel.
The green signal LED varies in brightness corresponding to the real-time input or
output signal level (see item d, below). It begins to light at – 60 dBFS increasing
in steps to full intensity as the signal level increases. When the signal level reaches
– 3 dBFS or above, the red clipping LED lights and remains lit as long as the signal
remains above – 3 dBFS. When it falls below that level, the red LED remains lit for 200
milliseconds, after which the display resumes real-time monitoring of the signal level.
d Output Indicators — Stacked red (signal clipping) and green (signal present) LEDs
for outputs 1 through 8. Each LED stack represents one output channel.
