Installation and Operation Instructions
The Point Sensor Vibration wireless pressure sensor transmits a digital value representing
vibration, or other vibration levels from various range sensor elements and a unique serial
number to a 418 MHz receiver. The Point Sensor Vibration is enclosed in a high impact
ABS enclosure for direct surface mounting in the environment to be measured. Point
Sensor Vibration is battery operated, the battery may be replaced by the user.
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 vibration 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 Vibration will not transmit. The Point Sensor
Vibration 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 Vibration wireless sensor.
The battery will last for more than 10 years in the idle state (as shipped from the
manufacturer). The Point Sensor Vibration will transmit data for as long as 3 years at a
rate of once each 30 seconds once started. The Point Sensor Vibration is completely
covered with a conformal coating to protect the electronics from the environment and
condensation. The Point Sensor Vibration may be placed in a quiescent state (battery life
greater than 10 years) by holding the installation switch closed for more than 5 seconds.

Wireless Vibration Sensor 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 HA9-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 vibration level as a 12-bit number
2-byte CRC-16 error check
The HA9-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 vibration data as a 12-bit number stored
MSB first. A value of 0FFF is a full scale reading. A zero input
vibration 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
FCC ID: M5ZVM1
Example:
41283FA60B000000EC000F8AD0AB<CR>
This field is the mode indicator, the LS-bit which indicates the
service state of the transmitter, C1=normal, C0=service mode.
41283FA60B000000EC000F8AD0AB <CR>
This field is the unique serial number of the 1-Wire sensor.
41283FA60B000000EC000F8AD0AB <CR>
This is vibration data field stored MSByte first as a 12-bit number
in a 16-bit field. The number shown is 000F (15) or 15/4096 of
full scale. Use the calibration points printed on the sensor to
calibrate the sensor for full range vibration readings.
41283FA60B000000EC000F8AD0AB <CR>
This field is the CRC-16 error check as was originally received and
checked. This CRC is over the first 11 bytes of the packet starting
with the mode flags and ending with inclusion of the temperature
data.
41283FA60B000000EC000F8AD0AB <CR>
This field is the mod 256 sum of all the ASCII character values in
the response but does not include the <CR>.
4828AE9105000000AA2D2DD474AB <CR>
This is the CR terminator, 0Dhex.

FCC Radio Frequency Interference Statement
Wireless Vibration Sensor FCC ID: M5ZVM1
NOTE: This equipment has been tested and found to comply with the limits for
a Class B digital device, pursuant to Part 15, Subpart B, of the FCC Rules. This
equipment generates, uses, and can radiate radio frequency energy. If not
installed and used in accordance with the instructions, it may cause interference
to radio communications.
The limits are designed to provide reasonable protection against such
interference in a residential situation. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does
cause interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try and correct the
interference by one or more of the following measures:
Reorient or relocate the receiving antenna of the affected radio or television
Increase the separation between the equipment and the affected receiver.
Connect the equipment and the affected receiver to power outlets on separate
circuits.
Consult the dealer or an experienced radio/TV technician for help.
MODIFICATIONS
Changes or modifications not expressly approved by Point Six Inc. could void
the user's authority to operate the equipment.
