Theory of Operation The OTX-900-HH-LR8-PRC Long-Range Handheld Transmitter uses a HumPRC Series transceiver to form a simple, yet highly reliable RF remote control transmitter. The HumPRC Series transceiver is a low-cost, high performance FSK radio that utilizes a proprietary Frequency Hopping Spread Spectrum (FHSS) technique and over-the-air protocol.
Contention Considerations It is important to understand that even though the transmitter uses a frequency hopping protocol, it is still possible for interference to interrupt the transmissions. While the transmitted signal consists of encoded digital data, only one carrier of any particular frequency can occupy airspace without contention at any given time.
Joining a Transmitter The handheld transmitter is associated with a receiver using the built-in Join Process. This process configures a star network with the central unit as the system Administrator. Other units are added to the network as nodes one at a time. Typically, the handheld transmitter is added as a node to a module that has been configured as an administrator.
Labeling / Instruction Requirements The transmitter has been pre-certified for FCC Part 15 and Industry Canada license-exempt RSS standards for an intentional radiator. It has already been labeled in accordance with FCC and Industry Canada regulations. No further labeling of the unit is needed; however, it is necessary to include the following statement in the end product’s instruction manual or insert card.
Additional features can be enabled through the module's Command Data Interface. The data guide and additional documentation for the HumPRC Series transceiver can be found on the Linx Technologies website at www. linxtechnologies.com. –...

Operation with the HumPRO Series The commands from the handheld transmitter can be received by a HumPRO Series transceiver. The transmitter should be joined to the HumPRO Series module in the same manner as it would be joined to a HumPRC Series module.
