3.1 Power Connection
3.1.1 Voltage
The Mini-Matrix operates at a DC voltage of 12V +/- 5%.
CAUTION: Operating the unit at an incorrect voltage may cause
damage, possibly voiding the warranty.
3.1.2 Power Connection
Perform the following steps to correctly power on the Mini-Matrix:
1. Connect all Ethernet cables and/or USB cables before turning on the
Mini-Matrix. This is because the drivers are downloaded on boot up by
a Linux kernel.
2. Connect the male end of the supplied wall plug-in power supply to the
female receptacle on the rear panel.
3. Connect the other end of the supplied wall plug-in power supply to a
grounded AC outlet.
Note: When powering up the Mini-Matrix it takes about 30-40
seconds to boot up and be operational.
3.1.3 Powering Off Safely
There is no power off switch for the Mini-Matrix, so follow the directions
below when powering off the Mini-Matrix.
1. Make sure no commands are being executed.
2. Exit out of HyperTerminal, the webpage, or any other control software.
3. Now it is safe to unplug the power.
Caution: Do not power cycle the Mini-Matrix quickly. Power cycling
quickly may corrupt the SD card, and the Mini-Matrix will not work
properly. Wait a minimum of 10 seconds between power cycles.
