Point Six, Inc. – 391 Codell Drive - Lexington, KY – 40509 - http://www.pointsix.com - 859-266-3606 – Fax: 859-266-0702 FCC ID: M5ZIRPC2 Installation and Operation Instructions for the Wireless IR Counter. Point Six, Inc. Wireless IR Counter Model Point Sensor IR Counter Installation and Operation Instructions Description The Point Six IR Point Sensor is a battery operated infrared beam interruption sensor with a 418 MHz radio transmitter. The sensor consists of two parts; the IR transmitter and the IR receiver. The IR receiver has an integrated 6-digit LCD counter and a radio transmitter for truly wireless installation and operation. The IR transmitter produces 16 pulses of IR each second across a distance of up to 60 feet in low power mode and 100 feet in high power mode. The user can select the power mode by pushbutton on the IR transmitter. The IR transmitter flashes 16 pulses of high intensity IR each second. The nature of these IR pulses is such that the IR receiver can distinguish them from any other source of IR. This characteristic allows the IR sensor to operate in almost any environment without interference from ambient lighting. The IR Point Sensor is designed to require very little energy; the 3 3.6 Volt Lithium batteries will operate the IR receiver for up to 8 years in normal operation. The IR receiver and IR transmitter can be placed in a Shipping Mode to lower energy usage and to prevent Radio transmissions during shipping. Holding the pushbutton down for a period of time greater than 10 seconds and then releasing will enter Shipping Mode. IR receiver Shipping mode is indicated by the LCD display counting automatically 1 count each second. When shipped from the manufacturer the IR counter will always be in Shipping Mode. A rapid flashing of the LED indicates IR transmitter shipping mode when the pushbutton is pressed for less than 4 seconds. Shipping mode is terminated by entry into Online Mode. Online mode is entered from Shipping Mode by pushing and holding the pushbutton for greater than 4 seconds and less than 8 seconds or for the IR receiver until the LCD display clears to zero. While in Online Mode the IR Point Sensor can be placed in Shipping Mode by pushing and holding the pushbutton for greater than 8 seconds, upon release the IR Point Sensor will enter Shipping Mode and will begin counting on the LCD display once each second. Note that both the receiver and the transmitter are shipped in Shipping Mode and must be placed in Online Mode for normal operation. The IR transmitter indicates shipping mode by a rapid flashing of the LED whenever the pushbutton is pressed for periods of less than 4 seconds. While in Online Mode the user can place the receiver in Setup Mode by pushing the pushbutton for a short time of 1- 4 seconds. The receiver will be placed in Setup Mode to aid in alignment of the transmitter and receiver. For a period of 2 minutes the LED on the receiver will glow to indicate the Point Six, Inc. – 391 Codell Drive - Lexington, KY - 40509- http://www.pointsix.com - 859-266-3606 - Fax 859-266-0702 2 reception of the IR beam from the transmitter. After two minutes or 8-seconds of uninterrupted beam the receiver will exit Setup Mode and return to Online Mode. In Online Mode the LED on the front of the receiver will flash briefly each time the IR beam is interrupted. The LCD counter will count each beam interruption and the internal 24-bit counters will count the beam- interruption and the beam- interruption-time. The LCD counter and the internal 24-bit counters will perform a Counter Reset each time the push button on the IR receiver is pushed and held for more than 4 seconds. Counter reset is best performed after the receiver and transmitter have been setup for Online Mode operation using Setup Mode. High Power Mode is entered by pressing and holding the pushbutton, after 4 seconds the LED will come on steady for 2 seconds. Release the pushbutton during the 2 seconds while the LED is on to enter High Power Mode. The LED will remain on for 5 seconds after pushbutton release to indicate High Power Mode. High power mode increases the IR range to 100 ft. and reduces the battery life. Low Power Mode is set by pressing and holding the pushbutton, after 4 seconds the LED will come on steady for 2 seconds. Release the pushbutton after the 2 seconds while the LED is off to enter Low Power Mode. The LED stays off immediately after pushbutton release to indicate Low Power Mode. Low power mode reduces the IR range to 60 ft. and increases battery life. Every 30 to 37 seconds or within 10 seconds of a beam status change the receiver will transmit a data packet using the onboard 418 MHz radio.

FCC ID: M5ZIRPC2 Operational description of the Wireless IR Counter, Model Point Sensor IR Counter Description of the circuit functions, ground system and antenna of the Point Six, Point Sensor IR Counter Wireless transmitter The Point Sensor wireless IR Counter transmitter is a lithium battery operated, microprocessor based, 418 MHz. transmitter that transmits IR beam, open-state counter and total beam open time counters and a unique 30-bit serial number. The microprocessor is brought up from a power down state every 1/16 second by a 32768 Hz, oscillator connected to ripple carry counter divider to produce a wakeup period of 1/16 second. The microprocessor looks for IR pulses from an IR sensor connected to an input of the microprocessor, and determines the beam open/closed status from these pulses. The microprocessor counts the 1/16 interupts and upon accumulating a total count of 480(30 seconds ) the microprocessor counts the beam interrupt cycles and then combines the counts and IR sensor status with the serial number data from an onboard stored unique serial number and then transmits the entire data packet serially with a Linx Technologies TXM-418-LC-R 418 MHz. Transmitter module. The microprocessor then powers down into a quiescent state to wait for the next interrupt from the oscillator divider. The PC board bottom layer is a ground plane and the antenna is a 1/4-wave loop that has been etched in PC board material and placed into the ABS enclosures cover. The entire electronics is coated with conformal coating to protect it from condensation.

Shortened antenna wire to 0.75 inches. Test Results: Tables 1, 2, and 3, and the Transmitted Bandwidth measurements show that this unit meets the radiated interference requirements of FCC Part 15, for an intentional radiator licensed to operate at 418MHz under Section 15.231(e). For the fundamental, under Section 15.231(e), the average limit is calculated by linear interpolation from 1500uV/m at 260MHz, to 5000uV/m at 470MHz when measured at 3m. Average limit = ((5000uV/m-1500uV/m)*(418MHz-260MHz)/(470MHz-260MHz))+1500uV/m = 4133uV/m = 20*log(4133) dB(uV/m) = 72.33dB(uV/m). Section 15.35(b) sets the peak limit for the fundamental to 20 dB above the average limit, or 92.33dB(uV/m). For spurious emissions, Section 15.231(e) sets the average limit to 20dB below the maximum permitted fundamental level, or 52.33dB(uV/m). Section 15.231(b)(2) permits this same limit of 52.33dB(uV/m) to be used for quasipeak measurements. Section 15.35(b) sets the peak limit to 20dB above the average limit, or 72.33dB(uV/m). Section 15.209 permits 53.98dB(uV/m) quasipeak from 960-1000MHz, 53.98dB(uV/m) average above 1000MHz, and with Section 15.35(b), 73.98dB(uV/m) peak above 1000MHz when measured at 3m.

To Whom It May Concern: The Point Six, Inc. wireless IR Counter transmitter (model Point Sensor IR Counter) transmits a 14-16 millisecond packet once each 600-10 seconds. This is identical to the data packet timing of a previously certified “M5ZWOW”. The packet consists of transmitter-on/transmitter-off timing that represents the serial number and counter data. The duty cycle is approximately 50%. The packet time can vary with serial number between 14- 16 milliseconds. The packet data is controlled by a microprocessor whose timing is based on a ceramic resonator that is very stable. The packet below (figure #2) illustrates a typical data packet, the worst case, 16 milliseconds, cannot be shown because serial number would have to be forced to make this so. Figure #1 illustrates the overall timing; a packet is sent each 10 seconds in this worst case. The batteries used during the tests were new and were standard 3.6 Volt Lithium cells. The batteries are a 3.6 Volt Lithium chemistry, which have a flat discharge curve from new to about 90% used. In this application the batteries require about 8 years to discharge to the point that they cannot be used. The batteries were used for no other purpose and had operated in the test unit for only a short time when the test was performed. The label will be Flexcon 2 mil PM200S mylar with a Flexcon 1 mil PM100C Polyester laminate. John I. Compton President, Point Six, inc.
