Installation and Operation Instructions for the Point Six Wireless Sensor.

Point Six, Inc.

Wireless Sensor Model WOWPIR

Installation and Operation Instructions

The WOWPIR wireless Personal iButton Reader transmits a digital value representing

either the unique serial number of a touched iButton and a 16 bit field representing the ID

of the PIR to a 418 MHz receiver. The WOWPIR is enclosed in a high impact ABS

enclosure for direct surface mounting in the environment to be measured. WOWPIR is

battery operated

Application: Touch the iButton reader port to the iButton to be read. The red LED will

flash to indicate a successful read and transmission of data.

Battery: A 3.0 Volt lithium battery powers the WOWPIR wireless iButton reader. The

battery will last for more than 5 years in the idle state (as shipped from the manufacturer).

The WOWPIR will transmit data approximately 200,000 times before the battery must be

replaced. The WOWPIR is (other than the battery) covered with a water resistant rubber

coating to protect the electronics from the environment and condensation. The user can

replace the battery. The WOWPIR may be placed in a quiescent state (battery life greater

than 5 years) by covering the reader port with a nonconductive material such as tape.

Wireless PIR 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 of touched iButton

2-byte serial number of the PIR

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 touched iButton.

2-byte data this field contains the 16-bit serial number of the PIR.

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:

C90C188C040000001B483BA4BCA5B<CR>

This field is the mode indicator, the LS-bit which indicates the

service state of the transmitter, C9=normal.
