COMMUNICATION CERTIFICATION LABORATORY TEST REPORT: 73-6560 FCC ID: NQE1005 NQE1005 TIM TRANSMITTER Functional Description General Description The TIM Transmitter remains in "sleep" mode until an input event occurs. The TIM Transmitter wakes up to monitor and accumulates switch closures. Events represent units of power or other similar items measured. Events are monitored by closures between pins 1 and 6 of connector JP2.

No sleep is event count equal to preset count is contact closed No Yes Yes advance TX channel 1ms wakeup setup PLL 4ms 1 to 255ms debounce Inc event count Transmit accumulator count 37ms Detailed Description The 4 MHz crystal (Y1) will provide a reference clock for the synthesizer IC (U2) and the microcontroller (U1). U1 will program the dividers in U2 to values that will select the appropriate frequency.

COMMUNICATION CERTIFICATION LABORATORY TEST REPORT: 73-6560 FCC ID: NQE1005 WinGate 2000 TIM RECEIVER Functional Description TIM RECEIVER DESCRIPTION Overview The TIM Receiver is a frequency-hopping receiver with an IF bandwidth of 330KHz. It continuously hops through the 25 specific frequencies it has memorized, stopping just long enough at each frequency to determine whether valid data is being received.

COMMUNICATION CERTIFICATION LABORATORY TEST REPORT: 73-6560 FCC ID: NQE1005 air-core inductor. The PLL provides voltage in the range of 0.5V to 4.0V (measured at TP4) to the varactor for tuning the 1st LO frequency. The air inductor must be tuned by hand to center the VCO response for the given voltage input. A control voltage of 0.5 volts corresponds approximately to an output frequency of 960 MHz while a control voltage of 4.0V corresponds approximately with an output frequency of 990 MHz.

COMMUNICATION CERTIFICATION LABORATORY TEST REPORT: 73-6560 FCC ID: NQE1005 Receiver and System Description The NQE1005 is the companion to the WinGate 2000 Receiver from World Wireless Communications. This receiver fast scans all twenty-five channels listed in the hopping table. If valid data is detected from one of the Transmitters it stays on that channel long enough to accept an entire packet of data.

COMMUNICATION CERTIFICATION LABORATORY TEST REPORT: 73-6560 FCC ID: NQE1005 Example System Operation Let us assume a system with 16 TIM Transmitters and one WinGate 2000 TIM Receiver. Each TIM Transmitter is attached to meters with event counts set to allow transmitters to transmit depending on meter demand from a few minutes to several hours. As each TIM reaches the condition were the event count equals the preset count the contents of the accumulator will be sent to the receiver.

COMMUNICATION CERTIFICATION LABORATORY TEST REPORT: 73-6560 FCC ID: NQE1005 NQE1005 TIM TRANSMITTER Specifications Data Transmission The NQE1005 TIM Transmitter will transmit 11 bytes of data every time the event counter capture matches the programmed interval. Each transmission occurs on one of 25 distinct frequencies between 905.8 and 924.2MHz. Sync Flags 65 sync flags (data 7Eh) will be sent out to allow receiver to synchronize on the transmission frequency.

COMMUNICATION CERTIFICATION LABORATORY TEST REPORT: 73-6560 FCC ID: NQE1005 Address 32 bit (4 Byte) programmable address stored in non-volatile memory Transmission Interval Programmable interval from 1 to 10000 used to update the next transmission capture count. Interval stored in nonvolatile memory. Pulse debounce Duration Programmable from 1 to 255 ms with 50 ms set as factory default.

COMMUNICATION CERTIFICATION LABORATORY TEST REPORT: 73-6560 FCC ID: NQE1005 Data Transfer – Read After accepting the handshake sequence, the TIM will read in the next 8 bits of data that is presented on the Pdata pin when the Pclk pin transitions from low to high. If the 8 bits is a ‘05’ hex, the TIM will transmit the next 72 bits as data out on the pushbutton input pin.
