FCC ID:
M5ZCNT
16-bit data field
this field contains 12-bit analog data stored in stored MSByte first
in 12-bit form
this field is unsigned and has a range of 0 to 4095 (0000-0FFF)
hex.
2-byte CRC-16
this is the originally received data packet CRC-16 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; the checksum is added
by the HA8 and is not a part
of the transmitted data.
Form:
“
CountTemp”
Wireless Counter/Temperature Transmitter
IDSSSSSSSSoooooottttLLCCCCKK<CR>
Note: All fields are in ASCII Hex
“ID”
The device type field: CountTemp has device type 61 hex. A 60 hex when in service
mode.
“SSSSSSSS”
The MS-30 bits of these 4-bytes are the serial number of the CountTemp. The LS-2 bits
are the status flags for the
open and
closed switch input status
. The LS bit (
bit-0) is
the Open status flag
and the next most significant bit
(bit-1) is the Closed status flag.
“oooooo”
This 24-bit field is the Open counter stored LS-byte first.
Count of switch openings
.
“tttt”
This top 16 bit of this 24-bit field is Temperature in two’s compliment 16-bit data stored
MSB first in 1/16 deg. C units. The least significant 8 bits of the 24-bit field are zero.
“LL”
This field is unused and will always read zero.
“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.
