NRLM90SXCRN1900 MHz Half Duplex Transceiver

The user manual will contain a page with the following statement pertaining to the potential interference and the requirement to use shielded cables to connect to the user device. INSTRUCTION TO THE USER This equipment has been tested and found to comply with the limits for a class C 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: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and 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. This equipment had been certified to comply with the limits for a Class C intentional radiator 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 the manufacturer, could void the user’s authority to operate this equipment.

Tel: 949.752.0312 ♦=Fax: 949.752.5014 NON-TECHNICAL DESCRIPTION OF THE UNIT AND ITS OPERATION: The trasnciever is a fully synthesized, half-duplex low power 900 MHz transceiver for OEM wireless data communicationn applications. This transceiver is intended for low data rate peer to peer wireless links and wireless networking applications. It has been specifically designed for cost sensitive applications that do not require the overhead of onboard protocol processing. the system level functions of error detection, error correction and network protocol precessing are not handled by the transceiver and must be performed in the host system software. The M90SXCRN1 supports a standard RS-232C voltage level base band serial interface. The transceiver requires externally supplied regulated 5 volt DC power and an antenna. The onboard micro controller can be commanded to change frequency by the host to avoid interference or frequency contention problems.
