Users Manual

Gage Wireless, Inc. User’s Installation Guide Model # GRC - 24 FCC Warnings This equipment has been tested and found to comply with the limits for a Class B Residential digital 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, 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 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. This device is intended only for OEM integrators under the following conditions: 1) The antenna must be installed such that 20 cm is maintained between the antenna and users for all installations, and 2) The transmitter module may not be co-located with any other transmitter or antenna, and 3) The Module is approved using the FCC ‘unlicensed modular transmitter approval’ method. Therefore the module must only be used with the originally approved antennas. As long as the 3 conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.).
IMPORTANT NOTE: In the event that any of these conditions can not be met (for example certain laptop configurations, co-location with another transmitter, or use of a different antenna), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. Suggested End Product Labeling This transmitter module is authorized only for use in devices where the antenna may be installed such that 20 cm may be maintained between the antenna and users (for example access points, routers, wireless ASDL modems, and similar equipment). The final end product must be labeled in a visible area with the following: "Contains TX Module FCC ID: TCX-GRC-24 ". RF Exposure Statements That Must be Included in the Final Devices Users Manual The users manual for end users must include the following information in a prominent location "IMPORTANT NOTE: To comply with FCC RF exposure compliance requirements, the antenna used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. This device is approved for fixed or mobile applications. Portable conditions can NOT be allowed due to the RF exposure compliance requirements." Additional Information to OEM Integrators The end user should NOT be provided any instructions on how to remove or install the modular TX device. NOTE: ANY CHANGES OR MODIFICATION NOT EXPRESSLY APPROVED BY THE MANUFACTURER COULD VOID THE USER’S AUTHORITY TO OPERATE THE EQUIPMENT.
INTRODUCTION The GRC-24 is a data transceiver which can be operated both indoors and outdoors. It transmits and receives data on frequencies in the license-free 2.4 GHz Industrial, Scientific, and Medical (ISM) frequency band. Data rates up to 115Kb/s can be supported. It is designed to be built into a wide variety of application devices requiring data communication up to several miles. Several GRC-24 transceivers can be configured into a wireless network with some functioning as relays. The transceiver uses frequency hopping spread spectrum technology to mitigate interference. OPERATION The physical interface to the transceiver is through a 26-pin header. The transceiver is powered and data is sent to and from the transceiver through this header. The transceiver is powered from a 5-volt regulated supply capable of handling 1 amp supply current. The signals available at this connector are TTL level compatible signals. The signaling format is the same as RS-232 so only level conversion is required to connect the transceiver to a RS-232 compatible device. The signals and their corresponding actions are listed in TABLE 1. TABLE 1. Interface Connector Pin Functions Pin Name Designation Signal Function Direction 1 Ground Power Supply 2 Transmitted Data TxD Data To DCE 3 Clear to Send CTS Control From DCE 4 Data Set Ready DSR Control From DCE 5 Data Carrier Detect DCD Control From DCE 6 Ring Indicator RI Control From DCE 7 Received Data RxD Data From DCE 8 Request to Send RTS Control To DCE 9 Data Terminal Ready DTR Control To DCE 10 Datagram Control To DCE 11 Sig Status 14 +5 volts dc Power Supply 15 +5 volts dc Power Supply 17 LED - Link Indicator Output 18 LED - Power Indicator Output 19 LED - Tx Indicator Output 20 LED - Rx Indicator Output 26 Ground Power Supply
APPROVED ANTENNAS WARNING: The GRC-24 transceiver has been approved only for the specific omni-directional antenna listed in TABLE 2. The FCC regulations mandate that third party antenna substitutions require FCC certification by the party making the substitution. Manufacturer Model # Gain Gage Wireless, Inc. GAN-3-O 3dBi
