Nemesis Audio 2
9-PIN GPI: 9-PIN Female D-SUB connector, for connecting 8 GPI signals, primarily local
‘button boxes’, such as GO, STOP, PREV, NEXT boxes for operator controls. Switch contact is
made by connecting pins 1-8 (GPI 1-8) to GND (pin 9). Note that these inputs do not have
the same input protection circuitry as the XLR sockets.
MIDI: 9-PIN Female MINI-DIN connector, for physical MIDI IN/OUT via breakout cable.
Functions as a physical route for MIDI between the host OS and the outside world. Note that
the GPI messages generated by the buttons are merged with the MIDI IN signal to the host.
The breakout connector and cable is capable of supplying 2 independently driven MIDI Out
streams, though only 1 input stream is supported by the device (IN 1, OUT 1+2).
USB: USB Type B Connector for connecting the Windows/Macintosh Host. The device uses
class compliant drivers so shouldn’t need any specific drivers to install. See installation guide
later in this manual.
ACT: Activity Monitor. Illuminates Green during normal device operation. Flashes briefly Red
to indicate MIDI/GPI activity, and during power up cycle.
PWR: Power Monitor. Illuminates Green when the device is powered and enumerated by
the host operating system. If running the unit in standalone mode, this indicator will remain
Red.
GO and STOP buttons (UMT-2Di only): 2 in-built buttons for use as GO/STOP when the unit
is not connected to a suitable button box. Can also be used as additional buttons with a
button box connected.
Rotary Encoder (UMT-2Di only): A multi-turn encoder to rapidly generate MIDI Messages.
Each clockwise turn will generate one message, anti-clockwise clicks will generate a
different message (see MIDI Table for exact messages generated).
Standalone Operation
The UMT-2D/UMT-2Di are capable of running in a ‘standalone’ mode, without the need for
a host operating system.
In this mode, power is provided to the device via a suitable USB power adaptor, and the
power monitor will remain Red to indicate the system is powered, but no enumerated host
connected.
Any GPI MIDI events will then be present at the physical MIDI I/O connector (Outputs 1+2
on the breakout cable). MIDI IN in this mode is not supported.
