1- Receive Signal Strength Indicators
2- This LED will illuminate when the P400 Data port is configured as a RS485 port
3- When illuminated, this LED indicates that the modem is transmitting data over the air 4- This LED indicates that the modem is synchronized and has received valid packets
5- This LED will illuminate when the P400 Enclosed is connected to a power source (9-30 VDC)
6-Holding this button while powering-up the modem will boot the unit into COMMAND mode: the default serial interface will be active and temporarily set to operate at its default serial settings of RS232 and 9600/8/N/1
7-USB Port for configuration of module. Only available on new versions
8-RP-SMA Female Bulkhead Antenna connector. ATTENTION: DO NOT POWER the module without the Antenna connected
9-Vin+/Vin– is used to power the unit. The input Voltage range is 9-30 Vdc with at least 1A current requirement
10-Data Serial interface for connection to a PC (using a R232/RS485 to USB cable) or to Pixhawk / Paparazzi / MotionUAV flight controllers (using a RS232/485 to TTL convertor)
The module needs an independent 2A current power supply.
General Connection Mode
Please attach a RS232-USB transmission cable to the module, in order to connect it to the computer. The default standard interface rate is 9600. The required interface baud rate can be changed according to the requirements. To do so, you need the change the configuration of the module. Please do not change the configuration if you do not know what you are doing (please do it only if you are an expert), as you may brick the module.
