M5ZEPX1Engine Parameter Transmitter

FCC ID: M5ZEPX1 Installation and Operation Instructions for the Engine Parameter Transmitter Model EPX-1. Point Six, Inc. Wireless Engine Parameter Transmitter Model WOW-EPX1 Installation and Operation Instructions The WOW-EPX1 wireless engine parameter transmitter transmits engine temperature, air pressure, oil pressure, RPM, Runtime in hours and a unique serial number to a 418 MHz receiver. The EPX1 is enclosed in a 4X4X2 PVC enclosure for direct attachment to the firewall of the engine compartment. A 12-pin screw connector provides connection to 12V dc power, air and oil pressure sensors, engine temperature sensor and RPM sensor. A backup battery provides means to transmit status when primary power is lost. Application: Attach the PVC enclosure to the engine compartment firewall with bolts placed through the four-flange holes on the sides of the PVC junction box. Attach the engine sensors as is indicated on the enclosure lid drawing. The EPX-1 operates on 12 Volts DC . All sensors are provided power on the 12-pin quick disconnect screw connector on the bottom face of the PVC enclosure. . Battery: A 3.0-3.6 Volt lithium battery powers the WOWEPX1 wireless engine parameter transmitter whenever primary power is lost. The battery will last for more than 10 years in the idle state (primary power applied). The WOWEXP1 will provide backup function for as long as 2 years at a rate of once each minute once placed in backup transmission mode. The user cannot replace the battery. The EPX-1 may be placed in a quiescent state (battery life greater than 10 years and no transmissions) by removing the runtime backup iButton from the socket on the top surface of the PCB electronics. THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES, OPERATION IS SUBJECT TO THE FOLLOWING TWO CONDITIONS: (1) THIS DEVICE MAY NOT CAUSE HARMFUL INTERFERENCE AND (2) THIS DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE UNDESERED OPERATION FCC ID: M5ZEPX1 MADE IN USA Wireless Temperature Sensor Data Format The Point Six, Inc. 418 MHz wireless transmitters require a compatible receiver with the ability to receive, error check and provide RS232 and RS422/485 interface. This document describes the data format provided by the HA8-WOW, HA9-WOW or HA10- WOW 418 MHz. Receivers. The transmit packet from a receiver is approximately 15 milliseconds in duration and consists of 13 bytes of data: 1-byte ID/Mode field 8-byte serial number 2-byte temperature data 2-byte CRC-16 error check The WOW receivers process this packet. The receivers perform a CRC-16 error check on the packet. If the data is not accurate it is discarded. When a packet is received that is error free it is converted to a 29-character packet and transmitted out the serial port at 19,200 Baud. The data is transmitted serially in ASCII Hex format and terminated with a CR character. This format requires two bytes for each byte of data; 14 data bytes x 2=28 plus the CR is 29 characters The resulting binary data format of the packet is: 1-byte ID field this field will contain a byte whose LSBit indicates the service state of the transmitter, 0=normal, 1=service mode. 8-byte serial# this field contains the serial number of the 1-Wire sensor. 2-byte temperature this field contains the temperature data stored MSB first in two's compliment 16-bit form of 1/16 deg. C units. 2-byte CRC-16 this is the originally received data packet CRC as described above. 1-byte checksum the checksum is a mod 256 sum of all the ASCII character values in the response but does not include the CR Example: “EPX” Engine Parameter Transmitter C5 F1D61300050000070000BD2DE1<CR> string from an HA8 45 F1D61300050000070000BD2DE1<CR> string from an HA9 The device type field: LSX has device type C5/45 hex.

Bush, PE, NCE, President dBi Corporation FCC ID: M5ZEPX1 The photo below indicates that the 20 dB transmitted bandwidth of the Point Six Engine Parameter Transmitter is 46 kHz. This is well within the maximum bandwidth specified by 47CFR15.233(c). Point Six Inc. 391 Codell Drive Lexington KY 40509 Gentlemen: On Thursday, August 2, Jim Factor of Point Six and I performed the measurements required in 47CFR15.31(e) on the Point Six EPX, Engine Parameter Transmitter. The instrumentation used included a Hewlett-Packard model 8568B spectrum analyzer, an EMCO loop antenna model 7405-902, and a Hewlett-Packard model 6114A precision adjustable power supply. The loop antenna was securely fixed near the EPX and the following relative measurements of the 418 MHz output power were taken: 12.0 volts 7.00 dBm (ref) 10.2 volts 7.00 dBm 13.8 volts 6.80 dBm As can be seen from these measurements, the 418 MHz output power varies insignificantly with power supply voltage variation. Please feel free to contact me if there are any questions concerning these measurements. Very truly yours, Donald R. Bush, PE, NCE The cable assembly used to test the EPX-1 was made up of three sets of four conductor cat 5 cable , and one three conductor 24 gauge cable . All cables were 3 meters long and were in one meter bundles . the board has ferrites on all inputs. Point Six, Inc. 391 Codell Drive Lexington, KY 40509 859-266-3606 Fax 266-0702 Signed:______________________ ________Date:_________ D. R. Bush, PE, NCE, President dBi Corporation FCC ID: M5ZEPX1 To Whom It May Concern: The Point Six, Inc. wireless engine parameter transmitter (model EPX-1) transmits a 15-16 millisecond packet once each 600-10 seconds. This is identical to the data packet timing of a previously certified “M5ZWOW”. I will restate this timing below. The packet consists of transmitter-on/transmitter-off timing that represents the serial number and humidity/temperature 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 battery used during the tests was new and was a standard 3.6 Volt Lithium cell. The battery is a 3.6 Volt Lithium chemistry, which has a flat discharge curve from new to about 90% used. In this application the battery requires about 5 years to discharge to the point that it cannot be used. The battery was used for no other purpose and had operated in the test unit for only a short time when the test was performed.
