Note: There is a heartbeat implemented with the LEDs: All LEDs flash for a short moment about every 1 second if there is no antenna connected. This is to inform that the unit is anyway active and working.

PCB mounted LEDs:FPGA configured (next to DIP switch #1): If on, it indicates that th FPGA is loaded with code. This is red for the hardware version V1.0 and will become green for later versions. Hardware Handshake Status (next to DIP switch #10): If on, the hardware handhake prevents data to be sent to the interface. In real operation this LED should either be on for short time intervals or totally be off. It only can be on ifthe hardware handshake option is enabled with DIP #8. |
