DMU DIGITAL METERS UNIT FOR NXAMP
WARNING: NXAMP firmware should be at least
LOAD3_11
for the DMU to work.
If not, the DMU view meters won’t work.
Connections and start up
Be sure that the host NXAMP is disconnected from mains.
Connect the four
XLR-3 cables
between DMU back panel XLR connector (from
A
to
D
)
and the NXAMP analog inputs (marked
A
to
D
).
If any network card is fitted, you will need also to connect the three
RJ45 links
between
the DMU back panel RJ45 and the network card ports.
WARNING: RJ45 links should be at least CAT5e to be compatible with Gigabit links
of the NXDT104.
We recommend following this color code bellow if possible:
RJ45 link color
Network port
RED IN/1/Primary
BLUE OUT/2/Secondary
GREEN Remote/3rd
Then connect the
GPIO port
of the DMU to the GPIO port of the NXAMP using a straight
DB25 male/male cable.
Connect the NXAMP mains plug(s) and turn the NXAMP “ON”. Check the LOAD revision
while booting up; it should be
LOAD3_11
or above.
All LEDs will be on at startup for a short time, allowing an easy check that the unit is
correctly powered and that all LEDs are working. Then after a few seconds the view-meters
will represent the actual input level or analog and digital inputs, whereas the network LEDs
will show the network port status.
WARNING: NXES104 firmware should be at least
0x0D0E
for the network LEDs to
work. The NXES104 firmware revision can be checked with ESmonitor™. To upgrade the
firmware of the NXES104 you will have to download the
LOAD3_11
firmware (or above)
into the NXAMP fitted with this NXES104 through the IN or Remote port of this card.
If the view-meter does not work, check the GPIO setting of the NXAMP and ensure it is set
to
MODE 0
.
