Since the inputs and outputs on the BasicTX and BasicRX are transformer-coupled, you can not pass DC. The low end is about 100 kHz. You can make it much lower by replacing the transformers with other minicircuits parts which go down to 10 kHz or so. If you need DC, you would need to remove the transformers and put a differential to single-ended opamp circuit in there. Look at the AD8132 for examples of how to do this.
