Power Supply

Power Connectors

Main power is applied to the Tetra through a 4-pin connector (J15), with mating connector
VersaLogic VL-PS12-24 (12V). See the table below for connector pinout.
CAUTION:
To prevent severe and possibly irreparable damage to the system, it is critical that the
power connectors are wired correctly. The power connector is not fuse or diode
protected. Proper polarity must be followed otherwise damage will occur.

Note: The VL-EPC-2700 does not come with an on-board RTC backup battery. The VL-CKR-
TETRA Cable kit includes a User Interface breakout cable (VL-CBR-3407) that connects to the
J13 connector. It is an open ended-cable that can connect a backup battery on pins 29 (V_BATT)
and pin 30 (Return_Battery/Ground). A connector and/or external battery is then hardwired.

CPU

The Tetra uses a low power Arm i.MX6 quad-core processor featuring:
 i.MX 6Quad (quad Arm Cortex-A9 core) -

System RAM

The Tetra ships with soldered-on DDR3L RAM. 2GB of RAM is on standard products, but custom
options allow memory capacities down to 1GB or up to 4GB.
