SoarTronic UART2 Installation guide

SOARTRONIC UART Interface v2 quick manual
1. Power su ly oints.
12v battery voltage in ut. Use these two solder oints for 12v su ly.
By default, 12v su ly voltage is fed to the rj45 connectors and can be used for ower u
devices connected to the rj45 orts.
If needed 12v for each rj45 can be disabled by cutting co er stri e. Cutting oints are
marked by white circle.

2. RJ45 UART orts.
UART2 and UART3 onboard solder oints.
UART2 is rs232 level com atible serial ort, rs232 devices can be connected directly to this
ort.
UART3 is TTL com atible(0-5v) serial ort, and external max232 level sifter may be
required!

3.
Turn USB debugging on in your android settings.
Connect usb cable and ower u UART interface card, adjust charge current trimmer on
IOIO card to the osition that your android detect IOIO/uart interface.
Charge trimmer.
