Design Concerns
1. U.FL connector. Use Hirose U.FL connector U.FL-R-SMT to for connecting external antennas. See Roving
2. Powering the module. The RN-174 can be powered from the RS232 header, the UART interface or the power
3. Sensor Interfaces. Inputs must not exceed 1.2V. Sensitivity saturates at 400 mV. It is recommended that you

connector. You should only provide power on one of the three interfaces.
If powered from the RS232 header, apply 3 to 12 VDC on pin 9 and ground to pin 5 of the RS232 header.
If powered from the UART interface, apply 3.3 VDC on pin 1 and ground on pin 2 of the UART interface.
If powered from the power connector, apply 4 to 16 VDC
use the Sensor power output to drive any analog devices that are attached to the sensor pins.
Note the exception to this is Sensor pins 2 and 3. These have a resistor network in front of sensors 4 and 5
respectfully so they can be drive with up to 5 VDC.
jumper is in place the module will power up in adhoc mode. . If the jump is then toggled 5 times, the initial factory
default configuration will be RESTORED. This is useful for cases where the module is mis-configured and is no
long responding.
Having this jumper on at power up also arms the restore factory reset function. After power up, if jumper 1 is
toggled on and off five times while the module the configuration will be RESTORED to the initial settings. This is
very useful in cases where the module is mis-configured and no is long responding to commands.
