All transmitters aresupplied set to the same address. Toavoid contention with other units or tocreate unique relationships, the addresscan be changed. This is accomplishedusing internal DIP switches as shown.The switches are accessed by removingthe DIP switch access cover on the backof the transmitter.If the switch is on, the address line isconnected to ground, otherwise it is floating. The receiver's address must matchexactly in order for the units to communicate. Application Note AN00300describes in detail how to set the address to match any of the receivers offeredby Linx.

Characterized, but not tested.Notes THEORY OF OPERATION The CMD-HHCP-xxx Remote Command Unit combines the LR Seriestransmitter with an internal Splatch Series antenna with an on-board HoltekHT640 encoder IC to form a simple, yet highly reliable, RF remote-controltransmitter. The LR transmitter is a low-cost, high-performance synthesizedASK/OOK transmitter. The transmitter’s synthesized architecture delivers outstanding stability and frequency accuracy while minimi zing the effects of antenna port loading and mismatching. This reduces or eliminates frequencypulling, bit contraction, and other negative effects that are common to SAW-based transmitter architectures, providing a significantly higher level ofperformance and reliability.When a button is pressed on the remote unit, power is applied to the internalcircuitry and the encoder IC is enabled. The encoder then detects the logic statesof the address lines and button data lines. These states are formatted into athree-word transmission cycle that continues until the button is released. Theencoder data is used to modulate the transmitter, which, through the antenna,conveys the data into free space. On the receiver side, a decoder IC or custommicrocontroller is used to check the transmitter's address bits against theaddress settings of the receiving device. If a match is confirmed, the decoder’soutputs are set to replicate the transmitter’s button states. These outputs canthen be used to activate external circuitry required by the application.The transmitter is compatible with several Linx receiver products, including theLC, LR, KH, and OEM product families. For applications where range is critical,the LR Series receiver is the best choice due to its outstanding sensitivity. Whenthe transmitter is combined with an LR Series receiver and the HT658 decoderchip, ranges up to 1000 feet are possible. Applications operating over shorter distances will also benefit from the increased link reliability and superior noiseimmunity provided by the LR Series receiver.

575 SE ASHLEY PLACE ● GRANTS PASS, OR 97526 PHONE: (800) 736-6677 ● FAX: (541) 471-6251 4/19/2005 Compatible Electronics, This document contains information for the CMD-HHCP-xxx Compact Handheld transmitter that is required for you to complete testing and filing for FCC, Industry Canada, and CE certification. We are requesting certification on three frequencies for FCC and Industry Canada (315MHz, 418MHz, and 433.92MHz) and one frequency for CE (433.92MHz). A brief description of the unit and its operation follows: The CMD-HHCP-xxx Compact Handheld transmitter combines a synthesized archetecture OOK transmitter with an on-board encoder IC to form a simple yet effective RF remote-control transmitter. When a button is pressed on the remote unit, power is applied to the internal circuitry and the encoder IC is enabled. The encoder then detects the logic states of the address lines and button data lines. These states are formatted into a 3-word transmission cycle that continues until the button is released. The encoder data is used to modulate the transmitter that, through the antenna, conveys the data into free space. Once data is received, a decoder IC is used to check the transmitter's address bits against the address settings of the receiving device. If a match is confirmed, the decoder’s outputs are set to replicate the transmitter’s button states. These outputs can then be used to activate whatever external circuitry is required by the application. The transmitters may need a modification of a level adjust resistor (R3) to tune the output power to the maximum legal limit. A map of the board showing the resistor location, schematic, and graph of output power vs. resistor value are included in this document and a kit of various value resistors has been included in the box with the units to be tested. Please inform us of what value will give us the maximum legal output so that we may use that value in production. All of the transmitters are wired for continuous modulated transmission upon inserting the battery by shorting one of the buttons. This has been done to make your testing easier and is not done in production. The worst-case duty cycle is 43%. The battery holder is marked with a “+” on it to indicate polarity. Should you have any questions about the units, please do not hesitate to call Ammon Gomez ( [email protected]) or Justin Hopper ( [email protected]) at 1-800-736-6677 or (541)-471-6256. 575 SE ASHLEY PLACE ● GRANTS PASS, OR 97526 PHONE: (800) 736-6677 ● FAX: (541) 471-6251 Below is the board map for the transmitter showing the part locations. Note that R3 is the level adjust resistor, whose value will determine the output power of the transmitter.
