MatchBox USB
User Manual
2.1 – Connecting the MatchBox to a PC
All connections to the MatchBox USB should be made before the power is applied.
Connecting the MatchBox USB takes three steps…
Step 1) Attach the MatchBox USB to the required PC using the supplied USB cable.
Step 2) Attach the CobraNet I/F port to another CobraNet device directly or to a network switch that is part of the CobraNet
network. If connecting directly to another CobraNet device, ensure a crossover cable is used.
Step 3) Attach the power supply to the MatchBox power socket and plug the other end into a free AC electrical socket to
power the unit on.
The MatchBox should always be connected directly to a USB port on the host PC. Connecting the MatchBox via a hub is
not recommended and doing so will likely cause audio quality problems.
The MatchBox must have both a working USB and a working Ethernet connection to operate correctly. It monitors the
USB and Ethernet connections and if either appears not to be working, the MatchBox will reset itself in an attempt to fix the
problem. It is important to ensure that the connections are working correctly.
As soon as power is applied, the power LED on the front of the MatchBox will turn on. The device will attempt to join the
CobraNet network and the CobraNet Ethernet LEDs may become active. See section 4 on troubleshooting for details of the
LED states.
2.2 – Installing Under Windows
As soon as power is applied to the MatchBox the first time it is
connected to the PC, Windows will automatically detect the
device and begin to install the USB audio drivers. These drivers
are part of the Windows OS and should already be on the PC.
Windows will show various messages that will appear in the
system tray during this process. Once complete, Windows will
show a “device is ready to be used” message in the system tray
and the USB symbol will disappear.
Figure 2 - Audio Device Properties in Windows
It may take a while for the drivers to be installed,
particularly for the standard MatchBox; it has four devices to
install and configure. The speed of the PC being used will also
be a factor.
Windows will automatically set the first MatchBox device it finds
as the default sound device. For a Standard MatchBox, the
devices are installed in channel order, so the default device will
output using CobraNet channels 1 and 2. For the MatchBox
1x8, there is only one device and it will be set as the default.
To ensure the device is connected and correctly identified, open
the “Sounds and Audio Devices” configuration from within
Control Panel on the PC. The default audio device should now
be “Attero Tech MatchBox USB” as shown in
. Figure 2
If the MatchBox is disconnected from the PC or powered
down, Windows will automatically remove the device from the
list of audio devices.
Clicking on the audio tab shows the devices available for playback (output devices) and recording (input devices).
By default, all Standard MatchBox audio devices are all configured as outputs so all four devices should appear in the
playback drop down box. These will be named “Attero Tech MatchBox USB”, “Attero Tech MatchBox USB (2)”, “Attero Tech
MatchBox USB (3)”, and “Attero Tech MatchBox USB (4)”. Different device configurations will show up differently in the
playback and recording drop-down lists.
