M5ZLSX1Wireless limit switch

FCC ID: M5ZLSX1 Installation and Operation Instructions for the Limit Switch Transmitter model LSX-1. Point Six, Inc. Wireless Engine Parameter Transmitter Model WOW-LSX1 Installation and Operation Instructions The WOW-LSX1 wireless limit switch transmitter transmits opened-closed status and counter data with a unique serial number to a 418 MHz receiver. The LSX1 is enclosed in a metal limit switch enclosure with a plastic dome lid. The LSX-1 is a Lithium battery powered device that is mounted as a conventional limit switch on an automatic or manual valve actuator. The status and opened/closed counter values are transmitted once each minute. Application: Attach the LSX-1 as a conventional limit switch package to the valve actuator to be monitored. The LSX-1 is battery operated so no power connection is required. Remove the lid by backing out the four corner screws. Press the pushbutton located next to the limit switch package momentarily to start the adjustment LED function. For a period of four minutes two LEDs on the PCB will indicate the status of the opened/closed limit switches, this is provided as an adjustment aid for alignment of the magnetic limit switch actuators. During this four-minute adjustment period the LEDs will reflect the status of the limit switches. After this time period the LEDs will be turned off and will not follow the status of the limit switches. Battery: A 3.6 Volt lithium battery powers the WOWLSX1 wireless limit switch transmitter. The battery will last for more than 10 years in the. The user can replace the battery. 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: M5ZLSX1 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- WO W 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 processe 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 fieldthis 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 temperaturethis field contains the temperature data stored MSB first in two's compliment 16-bit form of 1/16 deg. C units. 2-byte CRC-16this is the originally received data packet CRC as described above. 1-byte checksumthe checksum is a mod 256 sum of all the ASCII character values in the response but does not include the CR Example: “ LSX” Wireless Limit Switch Transmitter 91 F1D61300050000070000BD2DE1 <CR> string from an HA8 11F1D61300050000070000BD2DE1<CR> string from an HA9 The device type field: LSX has device type 91/11 hex.

FCC ID: M5ZLSX1 Operational description of the Limit Switch Transmitter, Model LSX1 Description of the circuit functions, ground system and antenna of the Point Six, WOWLSX1 Wireless transmitter The WOWLSX1 limit switch transmitter is a lithium battery powered, microprocessor based, 418 MHz. transmitter that transmits switch status, open-state counter and closed-state counters and a unique 30-bit serial number. The microprocessor is brought up from a power down state every 1 second by a DS2417 time of day clock interrupt output. The microprocessor counts the total number of times that the limit switch inputs are activated and registers the current state of each opened or closed switch. The microprocessor counts the 1-second interrupt cycles from the DS2417 clock until the transmit period has expired. The microprocessor then combines the counts and switch status with serial number data from an onboard DS18B20 and 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 DS2417 clock. The PC board bottom layer is a ground plane and the antenna is a 1/4-wave loop that has been hot upset into the PVC cover to form a spiral. The electronics is housed in a metal box with a plastic lid.

Bush, PE, NCE, President dBi Corporation To Whom It May Concern: Point Six , Inc. 391 Codell Drive Lexington, Ky. 40509 606-266-3606 Fax 271-0702 The Point Six, Inc. wireless limit switch transmitter (model LSX-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.
