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

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 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 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
