NXAMPMK2 USER MANUAL PAGE 39 / 70
From the remote-control software NEXO NeMo, it is possible to create groups of devices and zones of
channels. They are saved in a document called session. When a session is online, the NXAMPmk2s are
aware of the groups and zones they belong to.
Because there can be up to two remote clients (instances of NeMo) connected at the same time to an
NXAMPmk2, with two different sessions, the NXAMPmk2 must be able to choose between the two.
Preferred Remote Client: the remote client (an instance of NeMo) from which groups and zones are taken.
When this client updates the groups and/or zones, the changes are automatically reflected on this page.
Groups and zones are persistent even after the remote client is disconnected. They are then updated next
time this client is connected.
By setting another Preferred Remote Client, groups and zones are then taken from the other client.
If no Preferred Remote Client has been manually set (default), the groups and zones are taken from the
latest connected remote client. They are still automatically updated and preserved after the last remote client
is disconnected.
The groups and zones are displayed for informational purposes, as well as to provide a way to identify
quickly the devices: the tint colour of the screen can depend on the group the NXAMPmk2 belongs to. To
do so:
Go to Options > Screen Appearance > Tint Colour and check Tint Colour Depends on Groups.
The tint colour becomes the colour of the last group this NXAMPmk2 belongs to in the session of the
latest/preferred remote client. It is automatically updated when groups change.
GPIO SETUP
The GPIO (Global Purpose Input/Output) port is foreseen to easily interconnect the NXAMPmk2 with other
units (remote control or monitoring units for example) without remote control software to develop. Many
functions can be affected to each input or output pin of this port, or a global usage of all the pins can be
affected.
The five LEDs to the left at the bottom of the screen are real-time monitoring the values of the input pins of
the NXAMPmk2’s GPIO port (Gray means low, Green means high, i.e. +5V).
The eight LEDs to the right are real-time monitoring the values of the output pins.
LEDs are in reverse order, as are the pins on the GPIO port (DB-25 connector).
GPIO CONFIGURATION
To select the GPIO configuration mode, press the top-right button:
•
DMU: GPIO port is connected to DMU for metering purposes.
•
Custom: GPIO port is used for custom control and monitoring. The functions associated to its pins can
be individually configured.
