General Description
The RTS model BTR-240 base station
transceiver is a rack mountable, full-duplex,
wireless intercom radio. The base station
provides a central relay location which
handles the audio traffic between the TR-
240 beltpacks.
A BTR-240 base station can be used to
support up to eight full-duplex wireless TR-
240 beltpacks and many more for beltpacks
in push-to-transmit mode.
The BTR-240 uses the IEEE 802.11b
technology to transmit / receive within one
channel of the 1 – 11 (2.412 to 2.462 GHz)
allowable channels of the 2.4 GHz ISM
band. Operation of the BTR-240 is license
free.
The typical line-of-sight distances for the
system may be 300 feet.
The transmit and receive antennas are
connected via unique reverse TNC
connectors on the rear panel of the unit.
The BTR-240 is powered via a 12 – 15 VDC
receptacle on the rear panel. A 12 VDC
power supply is supplied with the BTR-240.
