This software sets three parameters and causes them to be stored in nonvolatile memory A) Unit address. B) Contact debounce time C) Preset count. The installation of the NQE1005 TIM Transmitter requires a plug connection to an appropriate gas meter (or other appliance with a dry switch contact), that closes for each metered event. This connector provides power to the unit by connecting pin 1&2 through the wiring harness. The same connector and harness provides interface to the meter contacts. This completes the setup and installation of the NEQ1005 TIM Transmitter.

COMMUNICATION CERTIFICATION LABORATORYTEST 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. Events are accumulated and compared to a preset number (1 to 10,000 set at installation).When this count is reached it will trigger, transmitting a data packet containing the total accumulated count. This data is transmitted to a receiver station using FSK (Frequency Shift Keying) modulation, on 1 of 25 different frequency channels ranging from 902 to 928 MHz. The complete packet transmits within 0.043 seconds. After the data has transmitted, the transmitter returns to “sleep” mode and collects another set of data. This process is then repeated when the next preset count is reached and transmitted on the next frequency from the hop table. As an example, let’s say the meter count is at 1000 units of gas used and the preprogrammed event count is set at 10. The TIM wakes up 10 times to advance the accumulator but will only advance the transmitter channel on the tenth event. At this point the accumulated count of 1010 would be sent. All 25 transmit frequency channels are used before any given frequency is repeated. The worst case or shortest delay that the firmware allows is 0.043 seconds between channels. Accounting for switch debounce of 1ms, a wakeup time of 1ms, 4ms to setup the PLL, and 0.037 seconds to transmit. It takes 1.075 seconds to visit all 25 channels (0.043x25=1.075 seconds). Any one channel could be visited 9.3 times in 10 seconds (10\1.075 = 9.30). Total transmit time for any 10 second period is 9.3x .037 for 0.344 seconds, 0.4 seconds is COMMUNICATION CERTIFICATION LABORATORYTEST REPORT: 73-6560 FCC ID: NQE1005 allowed. is contact closed sleep No Yes 1ms wakeup 1 to 255ms debounce Inc event count is event count equal to preset count No Yes advance TX channel Transmit accumulator count 37ms setup PLL 4ms Detailed Description The 4 MHz crystal (Y1) will provide a reference clock for the synthesizer IC (U2) and the micro- controller (U1). U1 will program the dividers in U2 to values that will select the appropriate frequency. The output of U2 (pin 4) will be filtered (C14, R11, C15, R24, C35, C46, R33, C47, R32, and C46) and will provide the tune voltage for the Voltage Controlled Oscillator (VCO). The VCO consists of D1, D2, Q1, Q3 and their associated resistors, capacitors, and inductors. The output of the VCO (Q3) will provide the feedback (via C19 and R20) for U2 (pin 8) and will also feed the Power Amplifier. The Power Amplifier consists of a low pass filter (C49, L8, C50, L9, and C51), Q2, Q5 and their associated resistors, capacitors, and inductors. The output of the Power Amplifier (Q5) is then filtered by C33, C56, L10, C55, C24, C25, C62, C26, and C37. The output of C37 will then feed the antenna (the antenna is etched on the PCB). Serial data from U1-2 passes through a variable resistor (R2) and is low pass filtered by C41, R28, C42, R29, and C43. This signal then modulates the VCO using D1, C38, and C36. R2 sets the frequency deviation of the output frequency. When in “sleep” mode, U1 (pins 3 & 6) powers down the VCO and power amplifier by setting the base voltage on Q4 and Q6 to a high voltage (3.6 volts). Prior to transmitting, U1 pulls these two signals to a low (0 volts), which will apply power to the VCO and power amplifier. JP1 is used as an interface to do “on-board” programming of the micro- controller (U1). JP2-2 & 3 allows the battery (3.6 Volts) to be disconnected until the unit is installed out in the field. J2-4, 5, & 6 will provide an external interface to U1.

Therefore testing for RF exposure was not required. Enclosed below is page 2 from the installation manual instructing the installer to ensure that this 20 centimeter distance is maintained. Note to Installers: Must not install this equipment in locations that could cause RF exposure to persons where the distance is lees than 20 centimeters. Hardware Requirements Antennas: Built in: No connections required Power Supply: The NQE1005 Transmitter is a sealed unit with internal lithium 3.6 volt battery designed for 10 year service under normal conditions. No maintenance required. Receiver and System Description: The NQE1005 is the companion to the NQE1002 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. The on board processor then passes the data out to a data collection system and continues to scan for the next transmitter. After each transmission the transmitters advances to the next frequency in the hopping table. When the input count is reached a new packet is sent. This completes the cycle. See one typical implementation below.

The NQE1005 is a frequency hopping transmitter that is installed inside a gas meter or similar device. While in “sleep” mode it monitors the switch closures on pins 1 and 6 of connector JP2 (from the meter). These switch closures will be accumulated after a preprogrammed number of pulses (1 to 10,000 set during installation). A data packet containing the total counts is transmitted to a receiver station using Frequency Shift Keying (FSK) modulation. This transmission will be on 1 of 25 different frequency channels ranging from 902 to 928 MHz and will transmit for approximately 35 msec. After a packet of data has been transmitted, the transmitter will return to “sleep” mode to collect another packet of data. The above process will then be repeated (at the next frequency in the hop chart) once a complete data packet has been collected.
