Instructions

1. PRODUCT DESCRIPTION

Linear’s Xtended Range FM receivers and transmitters are designed for use in various
wireless remote control applications. The Model XR-D serial data output receiver is used for
specialty O.E.M. data acquisition and processing systems. When the Model XR-D receiver
detects a signal from its companion transmitter(s), it will output 9600 baud ASCII serial data
through its RS-232 style interface in “real-time” (no buffering) as the transmitted data is
received.

The XR-D receiver’s serial data output contains all of the information that can be sent from
any type of Linear’s Xtended Range transmitters. In a typical ins tallation, the receiver’s output
terminals would be connected to a computer through a user supplied custom made cable.
The computer would run user supplied software written to suit the needs of the application.
It could display and log the transmitted unit number, channel number, bank number, alarm
state, battery condition, status reports, and transmitter type. Alternately, the XR-D could be
connected directly to a line printer for specialty or diagnostic purposes.

Power for the XR -D receiver can come from an external regulated 12 VDC power supply
(Linear Model T-124DC) or from a 12-volt battery. A diode protects the unit from reverse
power polarity. The XR-D draws about 30 mA current.

Two antennas (sold separately) are available for the XR-D. The Model ANT-1A is an 8-inch
“rubber duck” antenna for short range applications (less than 1 mile). The ANT-1A requires
a CON-180A (straight) connector to mate the antenna to the transmitter. For a right angle
antenna, use the CON-180A plus the CON-90A.The Model ANT-2 is a 3-foot whip antenna
for use in long range or difficult installations where more range from the XR-D is required. A
common 9-foot 1/4 wave CB whip antenna can also be used with the XR-D for maximum
range.

The receiver is housed in a rugged weather-resistant metal enclosure with a sturdy SO-239
antenna connector and a water-t ight wiring strain relief bushing. Two indicators are v isible through
a window on the case. The green power indicator lights when the receiver has power. During
reception, the red RF indicator lights. A two-position single-packet option jumper allows selection
of one round of only new data for each transmission or all data sent for each transmission. Two

3. COMPONENT LOCATIONS 4. INSTALLATION TIPS 5. MOUNT RECEIVER CASE

If using the ANT-1A antenna: For best range mount the XT/XR unit to a metal plate w ith a
minimum size of 12" x 12". The ANT-1A antenna should extend above the mounting plate
and be free of obstructions. If the ANT-1A antenna cannot be mounted in the open, consider
using an extension coaxial cable with PL-259 connectors to move the antenna’s location.

The XT/XR series of radios operate in the 27 MHz Citizens Band (CB) and may use any CB
antennas or CB antenna ac cessories. Antennas, PL-259 extension ca bles and other adapters
are available at Radio Shack® or other electronics stores.

1 WARNING: THIS PRODUCT IS NOT TO BE USED IN LIFE SAFETY APPLICATIONS. FCC Rules allow

unlicensed high-power transmissions at or near the operating frequency of this product which may
interfere with, or even disable, normal operation of this radio device.

1 For U.S. installations only: The radios are required to comply with FCC Rules and Regulations as Part 95

Radio Control devices. As such, they have limited transmitter power and therefore limited range.

1 A receiver cannot respond to more than one transmitted signal at a time and may be blocked by radio signals

that occur on or near their operating frequencies, regardless of code settings.

1 Changes or modifications to the device may void FCC compliance and user’s authority to operate equipment.
1 Infrequently used radio links should be tested regularly to protect against undetected interference or fault.
1 A general knowledge of radio and its vagaries should be gained prior to acting as a wholesale distributor or

dealer, and these facts sh ould be communicated to the ult imate users.
