RF400 Series Spread Spectrum Data Radio/Modems

A remote RF400 can be connected to a CR23X’s or CR5000’s RS-232 port with a null modem DB9M/DB9M cable (CSI Item # 14392). See Appendix F for details on power supply.

4.4 Antennas for the RF400 Series

Several antennas are offered to satisfy the needs for various base station and remote station requirements. These antennas have been tested at an authorized FCC open-field test site and are certified to be in compliance with FCC emissions limits. All antennas (or antenna cables) have an SMA female connector for connection to the RF400. The use of an unauthorized antenna could cause transmitted field strengths in excess of FCC rules, interfere with licensed services, and result in FCC sanctions against user.

NOTE An FCC authorized antenna is a REQUIRED component. You must pick one of the antennas listed below.
