AsteRx-m Evaluation Board
In a typical configuration, connect the USB connector to your PC using a standard USB
cable, and connect your antenna to one of the antenna connectors of the AsteRx-m OEM
board.
The evaluation board is powered from the PC through the USB connector. No external
power supply is required.
The COM1 subD-9 connector can be used to communicate with the receiver’s COM1
serial port. Only the Receive (pin#2) and Transmit (pin#3) lines of the subD-9 connector
are functional. The electrical level is RS232.
COM2 and COM3 are available on 3-pin headers. COM2 is at RS232 level and COM3 at
LVTTL level. See picture above for a description of the header pins. Note that the
headers may not be mounted on your evaluation board.
