FCC COMPLIANCE NOTICE NOTE: 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 res- idential 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 guar- antee 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 and correct the interference by one or more of the following measures: -- Reorient or relocate the receiving antenna -- Increase the separation between the equipment and the receiver -- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected -- Consult the dealer or an experienced radio/TV technician for help READ ALL INSTRUCTIONS CAREFULLY before attempting to install or operate the RF Sensor Sys- tem. SAVE THIS INSTRUCTION MANUAL — This instruction manual contains important operating instruc- tions for the RF Sensor System. Warning! FCC Regulations state that any unauthorized changes or modifications to this equipment not expressly ap- proved by the manufacturer could void the user's authoriza- tion to operate this equipment.

The CPC 837-3510 Receiver is composed of three basic functional blocks: the power supply, the RF section, and the output communication section. The power supply is formed using a 120VAC-to-9VDC Class II transformer. The PCB has a connector on-board to allow connection of the power supply, some protection components, and a National Instruments LM340 5V voltage regulator. The RF section is composed of two antennae, a 0-degree phase power splitter, and a Linx Technologies RXM-418-LC receiver. The communication section is formed with a Motorola MC68HC705KJ1CDW, which decodes the base-band information, a Motorola MC68HSC705C8ACFN microprocessor which controls the output, an RS-485 output driver, and three LED’s to supply visual status information. Incoming transmissions are routed from the two antennae to the Linx Technologies RXM-418-LC via the power splitter, where they are converted to a base-band serial data stream. This serial data stream is decoded by the Motorola MC68HC705KJ1CDW which supplies the data via a parallel connection to the Motorola MC68HSC705C8ACFN microprocessor. The microprocessor outputs the data to the RS-485 driver (U3 on the schematic). The data flow is only in this one direction.
