B5DM532Wireless 2.4 GHz Intercom Base Station

BTR-240 Users Manual - Preliminary Page 1 of 8 Rev D – 4 / 18 / 2011 RTS Model BTR-240 Base Station Owners / Users Manual (Preliminary Information) 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. The front panel LCD display and buttons allow the following menus to be obtained: • RF operating channel • Microphone gain • Sidetone level • Transmit squelch setting • 2W / 4W intercom type settings and levels • Auxiliary In / Out settings and levels. • Speaker output setting and level. The front panel also has an on/off power control. A talk button, talk light, channel select button, channel select lights, and volume are also available for a user at the base station local headset.

The unit takes approximately 25 seconds to boot and its status is indicated with a progress bar on the LCD. After the unit has booted successfully, the Start- up screen displays the unit model and software versions for approximately 3 seconds. The Status Screen is the main information screen of the base station. It displays the current status of the system including: • RF Channel of operation • Association (how many full-duplex beltpacks are associated with the base station) • 2W / 4W intercom settings • Auxiliary input / output settings • Speaker setting indicator Once the Status Screen is displayed, it is ready to act as an access point and TR-240 beltpacks can be turned on. Once the TR-240 beltpacks are on in “wireless” mode, they will associate with the RF channel selected at the base station. 1 Setting the RF Channel The RF channel can be changed by two different methods: • Manual RF Channel Selection • ClearScan ™ NOTE: The RF channel of operation setting is remembered and the unit will continue to boot on the same channel until it is set differently by the user. NOTE: The RF channel of operation needs to be verified / set before turning on the TR-240 beltpacks. If a beltpack is already associated with a base station, it may not continue to associate once the channel is changed. If this occurs, the beltpack will need to be rebooted. 1.1 Manual RF Channel Selection To manually select an RF channel, navigate to the “RF Channel” menu item and press the <Set> button. The current RF channel will be blinking indicating that the channel is in “set” mode and ready to be changed. Using the <Up> and <Down> buttons, the RF channel is increased and decreased, respectively. Once the desired RF channel has been identified and blinking, pressing the <Set> button will select it and save the settings. Once …
