This system consists of two parts, the Receiver and Transmitter. The Receiver plugs into a 12v outlet on the dash of the motorhome. When the BrakeBuddy is activated in the towed vehicle, the Receiver will illuminate. The Transmitter plugs into the top of the BrakeBuddy and sends a signal to the Receiver when the BrakeBuddy is activated. Before towing, perform a simple test to assure your Alert System is operating properly. Have someone push the red test button on the BrakeBuddy and hold it for ten seconds while you are in your motorhome looking at the Receiver. The Receiver will illuminate for the full ten seconds without blinking. Do not do this while the motorhome is moving! The Alert Receiver will illuminate: (1) if the BreakAway pin is pulled; (2) when the test button is depressed; or (3) when the BrakeBuddy activates as a result of forward inertia (i.e., the braking of the motorhome). When the BreakAway pin is pulled, in addition to the Receiver illuminating, an audible buzzer will sound after ten seconds. This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: 1. Reorient or relocate the receiving antenna; 2. Increase the separation between the equipment and receiver; 3. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected; 4. Consult the dealer or an experienced radio/TV technician for help. This equipment has been certified to comply with the limits for a class B computing device, pursuant to FCC Rules. In order to maintain compliance with FCC regulations, shielded cables must be used with this equipment. Operation with non-approved equipment or unshielded cables is likely to result in interference to radio and TV reception. The user is cautioned that changes and modifications made to the equipment without the approval of manufacturer could void the user’s authority to operate this equipment. Receiver Transmitter

OSC Parallel Inputs D0-D7 Address Inputs A0-A9 RF STAGEENCODER STAGE figure 12: KH Series Transmitter Block Diagram MODULE DESCRIPTION The KH Series Transmitter/Encoder module combines a high-performance SAW- (Surface Acoustic Wave) based transmitter with an on-board encoder. When combined with a Linx KH series receiver/decoder a highly reliable RF link capable of transferring control or command data over line-of-sight distances in excess of 300 feet (90M) is formed. The module accepts up to 8 parallel inputs such as switches or contact closures and provides ten tri-state address lines for security and creation of 59,049 unique transmitter/receiver relationships. The KH’s compact surface-mount package integrates easily into existing designs and is friendly to hand production or automated assembly. THEORY OF OPERATION The KH series operation is straightforward. When the transmit enable line is taken high the on-board encoder IC is enabled. The encoder then detects the logic states of the data and address lines. These states are formatted into a 3- word transmission cycle which continues until the enable line is taken low. The encoder creates a serial data packet which is used to modulate the KH transmitter. The TXE-KH transmitter section is based on a simple but highly optimized architecture which achieves a high fundamental output power with low harmonic content. This insures that most approval standards can be met without external filter components. The KH transmitter is exceptionally stable over variations in time, temperature, and physical shock as a result of the precision SAW (Surface Acoustic Wave) device that is incorporated as its frequency reference. The transmitted signal may be received by any Linx KH receiver/decoder module or Linx LC receiver combined with the appropriate decoder IC. Once data is received it is decoded using a decoder IC or custom microcontroller. The transmitted address bits are checked against the address settings of the receiving device. If a match is confirmed, the decoder’s output(s) are set to replicate the transmitter’s button status. PIN DESCRIPTIONS: Pin 1 - GROUND/LEVEL Connect to quiet ground or insert series resistor to adjust output power. Pins 2,3,7,8,9,10,11,12 - DATA IN Logic level input pin. TTL- and CMOS-compatible. State of all pins is sent during transmission. Pins 4, 23 - GROUND Connect to quiet ground or groundplane. Pin 5 - POSITIVE SUPPLY (V CC 2.7-6 VDC) The supply must be clean (<20 mV pp), stable and free of high-frequency noise. A supply filter is recommended unless the module is operated from its own regulated supply or battery. Pin 6 - TRANSMIT ENABLE When taken high this pin initiates transmission. Transmission continues until the pin is restored low or power to the device is removed. Pin 13-22 - ADDRESS LINES Ten tri-state address inputs are used to set transmitter address to avoid contention and create unique tx/rx relationships. Note: tri-state means that the address lines have three distinct states, high, low, and floating. All address pin states must match that of the KH receiver module for transmission to be recognized. Pin 24 - RF OUT Connect to 50Ωantenna. POWER SUPPLY REQUIREMENTS The transmitter module requires a clean, well- regulated power source. While it is preferable to power the unit from a battery, the unit can also be operated from a power supply as long as noise and ‘hash’ are kept to less than 20 mV. A 10Ωresistor in series with the supply followed by a 10μF tantalum capacitor from Vcc to ground as shown at the right will help in cases where the quality of supply power is poor. figure 11: Supply Filter PHYSICAL PACKAGING The KH-TX module is packaged in a hybrid SMD module with 24 pads spaced 0.100" apart on center. The reflow compatible package is equipped with castellations which simplifies proto- typing or hand assembly while maintaining compatibility with auto- mated pick-and-place equipment.
