Installation and Operation Instructions
Wireless IR Field Disturbance Sensor
Model FDEZIO
2
Description: The IR field disturbance sensor counts directional disturbances in its IR field and transmits packets which
contain information pertaining to these counts. It is installed in locations where object counting is desired.
Service Switch:Briefly pass a magnet over the service reed to activate the module. .
Packet Structure: “DirectionCtr” (65/64)
IDSSSSSSSSaaaaaabbbbbbCCCCKK<CR>
Note: All fields are in ASCII Hex
“ID”
The device type field: Directional Counter has device type 65 hex. A 64 hex when in service mode.
“SSSSSSSS”
The MS-30 bits of these 4-bytes are the serial number of the Directional Counter. The LS-2 bits are
the status flags.The meaning of the status flags are:
Bit 1 Bit 0 State
0 0 Blocked
0 1 Okay
1 0 Line power alarm
1 1 Battery Alarm
“aaaaaa”
This 24-bit field is the direction “A” counter stored LS-byte first. Count s in Direction “A”.
“bbbbbb”
This 24-bit field is the direction “B” counter stored LS-byte first. Count s in Direction “B”.
“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 but not including CRC-16.
“KK”
This field is the mod 256 sum of all the binary data values as represented by the ASCII hex values in
the response but does not include the <CR>.
Note: “Blocked” is when the sensor’s beam has been blocked for typically 10 seconds.
Example Packet
