Installation and Operation Instructions for the Wireless IR Counter.
Point Six, Inc.
Wireless IR Counter Model Point Sensor IR Counter
Installation and Operation Instructions
Description
The Point Six IR Point Sensor is a battery operated infrared beam interruption sensor with a
418 MHz radio transmitter. The sensor consists of two parts; the IR transmitter and the IR receiver.
The IR receiver has an integrated 6-digit LCD counter and a radio transmitter for truly wireless
installation and operation. The IR transmitter produces 16 pulses of IR each second across a
distance of up to 60 feet in low power mode and 100 feet in high power mode. The user can select
the power mode by pushbutton on the IR transmitter. The IR transmitter flashes 16 pulses of high
intensity IR each second. The nature of these IR pulses is such that the IR receiver can distinguish
them from any other source of IR. This characteristic allows the IR sensor to operate in almost any
environment without interference from ambient lighting.
The IR Point Sensor is designed to require very little energy; the internal 3.6 Volt Lithium battery will
operate the IR receiver for up to 6.5 years in unbroken beam mode and 3 years in normal operation.
The IR transmitter can operate on a single 3.6 Volt internal Lithium battery for 1 year in low power
mode and 4 months in high power mode. High power mode is rarely used because the IR counter
has a separation range of 60 feet in low power mode and traffic pathways are rarely larger.
The IR receiver and IR transmitter can be placed in a Shipping Mode to lower energy usage and to
prevent Radio transmissions during shipping. Holding the pushbutton down for a period of time
greater than 10 seconds and then releasing will enter Shipping Mode. IR receiver Shipping mode is
indicated by the LCD display counting automatically 1 count each second. When shipped from the
manufacturer the IR counter will always be in Shipping Mode. A rapid flashing of the LED indicates IR
transmitter shipping mode when the pushbutton is pressed for less than 4 seconds.
Shipping mode is terminated by entry into Online Mode. Online mode is entered from Shipping
Mode by pushing and holding the pushbutton for greater than 4 seconds and less than 8 seconds or
for the IR receiver until the LCD display clears to zero. While in Online Mode the IR Point Sensor can
be placed in Shipping Mode by pushing and holding the pushbutton for greater than 8 seconds, upon
release the IR Point Sensor will enter Shipping Mode and will begin counting on the LCD display once
each second. Note that both the receiver and the transmitter are shipped in Shipping Mode and must
be placed in Online Mode for normal operation. The IR transmitter indicates shipping mode by a rapid
flashing of the LED whenever the pushbutton is pressed for periods of less than 4 seconds.

While in Online Mode the user can place the receiver in Setup Mode by pushing the pushbutton for a
short time of 1- 4 seconds. The receiver will be placed in Setup Mode to aid in alignment of the
transmitter and receiver. For a period of 2 minutes the LED on the receiver will glow to indicate the
reception of the IR beam from the transmitter. After two minutes or 8-seconds of uninterrupted beam
the receiver will exit Setup Mode and return to Online Mode. In Online Mode the LED on the front of
the receiver will flash briefly each time the IR beam is interrupted. The LCD counter will count each
beam interruption and the internal 24-bit counters will count the beam- interruption and the beaminterruption-time.
The LCD counter and the internal 24-bit counters will perform a Counter Reset each time the push
button on the IR receiver is pushed and held for more than 4 seconds. Counter reset is best
performed after the receiver and transmitter have been setup for Online Mode operation using Setup
Mode.
High Power Mode is entered by pressing and holding the pushbutton, after 4 seconds the LED will
come on steady for 2 seconds. Release the pushbutton during the 2 seconds while the LED is on to
enter High Power Mode. The LED will remain on for 5 seconds after pushbutton release to indicate
High Power Mode. High power mode increases the IR range to 100 ft. and reduces the battery life.
Low Power Mode is set by pressing and holding the pushbutton, after 4 seconds the LED will come
on steady for 2 seconds. Release the pushbutton after the 2 seconds while the LED is off to enter
Low Power Mode. The LED stays off immediately after pushbutton release to indicate Low Power
Mode. Low power mode reduces the IR range to 60 ft. and increases battery life.
Every 30 to 37 seconds or within 10 seconds of a beam status change the receiver will transmit a
data packet using the onboard 418 MHz radio.

Radio data packets are received and decoded by a Point Six receiver and presented
in the following format.
“IRcounter” format
IDSSSSSSSSiiiiiittttttCCCCKK
Note: All fields are in ASCII Hex
“ID”
The device type field: IRcounter has device type 11 hex. A 10 hex when in service mode.
“SSSSSSSS”
The MS-30 bits of these 4-bytes are the serial number of the IRcounter. The LS-2 bits are the status
flags for the beam status. The LS bit (bit-0) is the Open beam flag and the next most significant bit
(bit-1) is the Closed beam flag. An open beam is a beam that is currently interrupted.
“iiiiii”
This 24-bit field is the traffic counter stored LS-byte first count of beam interruptions.
“tttttt”
This 24-bit field is the total time in seconds that the beam has been interrupted since the last
counter reset.
“CCCC”
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 device type and ending with inclusion of the “cccccc” data.
“KK”
This field is the mod 256 sum of all the 8-bit binary values in the response but does not include the
.
Note: The “KK” field is added by the Point Six receiver and is not actually transmitted by the IR
Counter. This field is added to make it easier for the user to perform error decoding on the data
packet in cases where the user does not want to perform the CRC-16 error check. If the user
application performs a CRC-16 error check there is no need to use the “KK” data check.
