Connect the Antenna(s) to the Reader
Note
Use only authorized antennas and cables to maintain FCC approval. See
Appendix
A: Mercury4 Antenna Information on page 1.
 Connect antennas to the ports before applying power to the reader. Any port not
having an antenna connected to it will be disabled when the reader is powered on.
See Authorized Antennas
in Appendix A: Mercury4 Antenna Information for details
on antennas.
 Up to four antennas can be connected to the reader. Each antenna has two ports
which are connected in pairs to the reader: one for transmitting, the other for
receiving.
 While either port can be used to transmit or receive, for best performance we
recommend using the top port for Transmit and the bottom for Receive. See the
figure.
