COMMUNICATION CERTIFICATION LABORATORY TEST REPORT: 73-6560
FCC ID: NQE1005
Data Transfer – Read
After accepting the handshake sequence, the TIM will read in the next 8 bits of data
that is presented on the Pdata pin when the Pclk pin transitions from low to high. If
the 8 bits is a ‘05’ hex, the TIM will transmit the next 72 bits as data out on the
pushbutton input pin.

Data Transmission
The TIM Transmitter will transmit 11 bytes of data every
time the event counter capture matches the programmed
interval. Each transmission occurs on one of 25 distinct
frequencies between 905.8 and 924.2MHz.
Frequency
The TIM Transmitter will broadcast the accumulated data on
one of 25 frequencies in pseudo-random order.
Sync Flags
65 sync flags (data 7Eh) will be sent out to allow receiver
to synchronize on the transmission frequency.
Sync Byte
1 sync byte (data Aah) will be transmitted to indicate start
of packet
Address
32 bit (4 Byte) TIM address transmitted
Input Status
Status of secondary input reserved for future use. Status
of input reflected in the status byte sent at the time of
transmission
Counter
16 bit (2 Byte) up counter keeping track of switch closures
(normal state of input pin is active high). Counter will
increment on switch closure (negative edge).
