Figure 17 PCB stack cards
The cards perform the following functions:
 Unilon RX Card – decodes the signal sent from the receiving
antenna via the RF Card.
 RF Card – receives the signal from the receiving antenna
 Unilon Output Card – sends the data to a controller or
computer
 Unilon TX Card – encodes the signal to transmit
 Transmitter Card – sends the signal to the transmitting
antenna
The RX, TX and Output Unilon Cards (Figure 18) appear to be
physically the same with the exception of jumper placement, which
configures them for their respective tasks.
