I28MD-TRCV-9CMHZModular Low Power Radio Transceiver

916 Wireless 916 MHz Transceiver Part Number: CC15431-1 Features The Comtec Wireless 916 is a 916 Mhz radio designed for OEM applica- tions that operate in the unlicensed FCC band between 902-928 Mhz. The Wireless 916 can be used for commu- nications where physical connection Electrical Input Voltage:Vcc = 5 Volts +,-10% Power Dissipation:50mW (receive mode) 50mW (transmit mode) 5 mW (sleep mode) Current Consumption:10 mA (receive mode) 10 mA (transmit mode) 1 mA (sleep mode) Operating Frequency:916.5 Mhz Transmit Power Output:-5dBm (typical) Receiver Sensitivity:-85 dBm (typical) Out of band interfering signal rejection:60 dB (typical) Baud rate:user selectable, up to 19,200 bps J1 Pin Assignments:Pin #Signal Name 2 Description Pin 1sleep/awake*1 = sleep Pin 2Vcc Pin 3RXDReceive Data Pin 4TX/RX*1 = transmit Pin 5No connect Pin 6TXDTransmit Data Pin 7GND Pin 8GND J2 Pin Assignments:Pin #Signal Name (Optional)Pin 1GND Pin 2GND J3 Pin Assignments:Pin #Signal Name (Optional)Pin 1GND Pin 2GND is not desired. The following objectives can be achieved with the Wireless 916, (i) provides a limited range radio (20-30 feet line of sight), (ii) mini- mizes parts count and associated cost, (iii) acts as a cable replacement when used together with Comtec Wireless printers. When combined with Comtec’s In- telligent Wireless Controller (part number CQ13967), the Wireless 916 can be attached to any RS232C port. To minimize integration headaches, the Wireless 916 has modular FCC approval, which means that no ad- ditional FCC approval is required by the OEM 1 . Actual Size 916 Wireless Block Diagram (Part Number CC13626) SoftwareWhen the Intelligent Wireless Controller (P/N CQ13967) is not used, Comtec can provide C source code for a CS/CDMA collision avoidance communications protocol. This software supports multiple radio pairs operating in proximity to each other, and implements error detection, retries and radio address association. The radio address association algorithm is based on radio or product serial number. RegulatoryApprovals:FCC Modular, ID Number: I28MD-TRCV-9CMHZ Canada T.B.D.

The following steps have been taken to insure that I28MD-TRCV-9CMHZ (referred to below as “the module”) meets the FCC requirements for a modular approval: 1) All electronic components used on the module are on one side of the printed circuit board and are completely covered by metal shielding. There is an internal ground plane in the circuit board itself to complete the shielding. Only the connectors are exposed. 2) The TXDATA input is buffered on the module itself. Input voltage variations on TXDATA will not effect the modulation or the transmitter output power. 3) The module has it’s own on-board 3-volt regulator. All RF circuitry operates from this 3 volts. 4) The antenna connector used on the module has only one manufacturer and is not readily available. We have used the same connector on previous modular approvals and the FCC has considered it a non-standard connector. In addition, the module will only be used in devices with internal antennas of the type specified in the application. These internal antennas are not user serviceable or user replaceable. Therefore the antenna system meets the requirements of Section 15.203. 5) The module was tested in a stand-alone configuration using three different antennas. 6) Each module will be labeled with the FCC ID# and warning message as shown on the AA15431-1 drawing which is included with this application.
