Installation and Operation Instructions for the Point Sensor Analog transmitter.

Wireless Analog Sensor Model Point Sensor Analog

Installation and Operation Instructions

The Point Sensor Analog wireless analog level sensor transmits a digital value
representing either 0-20 MilliAmp, 0-5Volt or 0-10Volt levels and a unique serial
number to a 418 MHz receiver. The Point Sensor Analog is enclosed in a high impact
ABS enclosure for direct surface mounting in the environment to be measured. Point
Sensor Analog is battery operated

Application: Apply the sensor to a surface to with double-sided adhesive tape. Make
sure that the side labeled with FCC ID is visible and away from any metal surfaces.

Service Function: The wireless analog sensor has an installation mode switch. A
momentary push of this switch will start the convert/transmit cycles. When new and until
this button is pushed the Point Sensor Analog will not transmit. The Point Sensor
Analog will transmit a special installation status mark in the data packet immediately
after the installation/start switch is pushed. After the start a push of the installation
switch will result in the immediate transmission of data and ID and installation status
mark.

Battery: A 3.6 Volt lithium battery powers the Point Sensor Analog wireless sensor.
The battery will last for more than 10 years in the idle state (as shipped from the
manufacturer). The Point Sensor Analog will transmit data for as long as 10 years at a
rate of once each minute once started. The Point Sensor Analog is completely covered
with a water resistant conformal coating to protect the electronics from the environment
and condensation. The user may replace the battery. The Point Sensor Analog may be
placed in a quiescent state (battery life greater than 10 years) by holding the installation
switch closed for more than 4 seconds.

Data Format

The Point Six, Inc. 418 MHz wireless sensors 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 418 MHz. Receiver.

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 analog level as a 12-bit number
2-byte CRC-16 error check

The HA8-wow receiver processes this packet. The receiver performs 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. See the HA8-wow specification for details.

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 data this field contains the analog data as a 12-bit
number stored MSB first. A value of 0FFF is a full scale reading
and represents 20 milliamp. A zero input level will result in a
reading of 0000.

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
