System Board Diagram:
**Inserting SIM-Card
SIM-Card slot is located on the top right corner (Below SD-Card slot). (Insert Card Chip Face Down)
**Connecting Antenna
Antenna SMA Female Connector is located on the top left corner (Above System Processor). Antenna
comes with 6-feet wire; you can extend cable using SMA Coupler (female to Female). This can be
obtained from your local electronic store or any online Antenna Retailer.
**Wiring System Power Supply
System comes with 1-15V 1.5Amp transformer, you can splice cable right in the middle and extend
wiring distance with 2-conductor wire to reach designated power source. If distance is less than 75-feet,
22-guage 2-conductor wire should be fine. But if distance exceeds 75-feet, we recommend 18-guage 2-
conductor wire. Thickness of this wire will maintain stable current flow for runs over 100-feet or more.
