Tel: 949.752.0312 ♦ Fax: 949.752.5014 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 B 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 a 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 d 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 AC 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 has been certified to comply with the limits for a Class B 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 Module Compliance for the 900MHz Half-Duplex Transceiver M90SXCRN2 1. Shielding The 900 MHz transceiver, M90SXCRN2, is supplied to the user as a fully shielded module. All components are located on one side of a 3” x 1 15/16” circuit card. The backside of the circuit card is an unbroken copper plane connected to the system ground. The shield is seam soldered around its entire perimeter to the ground plane. The only components not contained within the shield are the RF output connector and the user interface (10-pin header). All connections to the user header pass through an EMI filter comprised of a ferrite bead and a bypass capacitor. 2. User I/O Each pin of the 10-pin header, other than 5.0 Volt DC power and ground, pass through a buffer, or level translator. Overdriving or under driving any of the data inputs has no effect on the amount of RF power, modulation spectrum, or operating frequency of the transceiver. 3. Power Supply The module operates from a nominal 5.0 ±5% Volt source. All circuitry critical to determining RF frequency or RF output power levels, operate from an internally regulated 3.3 Volt source. The module contains an under voltage/brownout reset circuit that fully disables the RF transmitter for input voltages of 4.8 volts or less. 4. Antenna The module was tested with a whip antenna. The antenna was connected to the module using an MMCX coaxial connector. This miniature coaxial connector satisfies the requirements as a “unique” connector. 5. Testing The module was tested in a stand-alone configuration (See Test Report). The serial port of a notebook computer was used as a data source for the module during testing. 6. Labeling The shield of the module contains the required FCC label (See Test Report). In cases where the module in installed within a customer’s device, an additional label containing the following wording will be provided: This device contains Transceiver Module FCC ID NRL90SXCRN2

DESCRIPTION The M90SXCRN1 is a fully synthesized, half-duplex low power 900 MHZ transceiver for OEM wireless data communication 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 processing 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. FEATURES Half duplex 900 MHZ RF transceiver for OEM data communications applications Operates in the 902 - 928 MHZ ISM Band, FCC part 15.249 RS-232C serial host interface (TXD, RXD, RTS, CD, DTR, GND) Supports baud rates of DC to 57.6K baud Supports non-standard baud rates generated from dedicated logic or micro controller I/O ports Fully synthesized for programmable channel selection Onboard micro controller and non-volatile storage enabling soft OEM configuration WIRELESS , INC.
