(PRELIMINARY)
The Vehicle User‘s Manual is preparation. The following material will be contained in the manual:
This device complies with Part 15 of the FCC Rules and with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference
that may cause undesired operation.
WARNING: Changes or modifications not expressively approved by the party responsible for
compliance could void the user's authority to operate the equipment.
GENERAL
This system provides the vehicle owner with compass‘ temperature. trip computer
infomtation, and integrated HomeLink®. The HOI'nELIl'lkj‘ portion of the circuit is separate
from the compass section. except that the compass microprocessor controls the power to
the HomeLink® section. and serially communicates to the HomeLink® mteroprocessor which
swttch has been pressed. All the following iiifon'nation refers to the HomeLink® part of the
system.
Operational Description
This system gives the vehicle owner the ability to use a garage door opener (GDO) that is
integral to the interior trim of the vehicle. The HomeLink® shall be capable of learning and
remembering variables required to emulate three different GDO transmitters. in the learn
mode ofoperation, the user selects one of three channels. The HomeLinki’ determines
the frequency. data and. where applicable. the Rolling Code manufacturer oftlie original
GDO transmitter (OT). The frequency and data stream or rolling algorithm parameters
(created within the OT's Rolling Code guidelines) are then stored in HOHAVOIMIIC memory
(NVM) for use in the transmit mode of operation. Once contained in memory. the
HomeLink® shall activate the given receiver by repeating. at the proper frequency, either a
fixed data stream or a hopping data stream created with the OT's Rolling Code algorithm.
HomeLink® Transmit Mode of Operation
If a selected channel has been previously trained, the HomeLink® shall operate in
transmit mode. To operate the HomeLink" in the transmit mode, the user shall activate
one of three transmit buttons. The Compass microprocessor shall determine which button
has been activated and send the information serially to the HomeLink‘!’ microprocessor.
which shall generate appropriate data at the proper frequency.
The VFD indicator shall be ON continually during transmit mode.
The VFD indicator shall rapidly blink (4Hz t 10%) for 2 i 10% seconds followed by
continuous illumination during Rolling Code PWM transmissions,
The HomeLink® will continue in the transmit mode for twenty (20 1 10%) seconds before
proceeding to the learning tuode of operation.
HomeLink® Default Mode of Operation
lfa selected channel has never been previously trained nor previously erased. the
HomeLink“? shall operate in default mode. To operate the HomeLink® in the default mode,
the user shall activate one of three transmit buttons. The HomeLink Q shall determine
which button has been activated, and using a predetermined identification code and
frequency (see Appendix B for details) shall transmit such data with the VFD indicator
continually on. The HomeLink® will continue in the default mode for twenty (20 i 10%)
seconds before proceeding to the lcaming mode of operation.
HomeLink® Rolling Code Default Mode of Operation
The user places the HomeLink® in rolling code default mode by simultaneously holding
down buttons one, two, and three for 30 1 10% seconds.
If buttons one. two and three are released while the VFD is mpidly blinking (< I0 seconds)v
all three channels will be cleared of data. When one of these channels is subsequently
activated, the device shall immediately enter the team mode of operation.
To operate the HoineLirtk® unit in the rolling code default mode, the user shall activate one
ofthe three transmit buttons. The HomeLink® unit shall dctemiine which button has been
activated and using a pre-detenriined code-hopping algorithm, bit period and frequency
(see Appendix B for details) shall transmit such data with the VFD indicator rapidly blinking
(4Hz t 10%) for 2 t 10% seconds followed by continuous illumination.
HomeLink® Learn Mode of Operation
The HomeLink‘i' system can learn up to three (3) separate garage door opener (GDO)
systems. To train a GDO transmitter to the H0meLInk® system. the user shall complete
the following steps:
- select one ofthree channels by selecting l ofthree transmit buttons. If more
than one channel is selected at one time. the HomeLink® shall give the lowest
numbered channel highest priority. For example if channel 2 and 3 are
selected. channel 2 shall have the higher priority.
- hold a transmit button for twenty (2th 10%) seconds at which time the learn
mode stizill be indicated. The HoineLink‘” shall be in learn mode only ifthc VFD
indicator is blinking at a rate of] Hz 1 10%. (The HomeLink® shall immediately
enter leam mode if the selected channel is determined to be clear of data. See
1.2.4)
- hold the present GDO transmitter near thd-lomcLink®. The HomeLinkQ shall
train when the OT is held within 1 inch, and shall not train ifthe GT is hold more
than 3 feet away from the unit. Once in team mode. the training process will be
complete in 590 seconds and shall be indicated by rapidly blinking thc VFD (4Hz
t 10%) 40 times. After completion the VFD indicator shall be off.
. the data containing the frequency of operation and security code information
shall be stored in non-volatile uicinoiy (NVM).
HomeLink® Clear Mode of Operation
The NVM ofthc l-lomcLink® can be completely emsed by simultaneously holding down
buttons one and three for 20 i lO% seconds. Successful erasure of the memory shall be
indicated by rapidly blinking the VFD indicator (4Hz t 10%) 40 times.
- If buttons one and three are released while the VFD indicator is blinking rapidly
(<10 seconds), all three channels shall be cleared of data. When one of these
channels i subsequently activated, the device shall immediately enter learn
mode ofopemtion.
- If buttons one and three are continually activated for more than 10 seconds after
the rapid blinking starts, the VFD indicator shall be off. When one of these
channels is subsequently activated, the device shall immediately enter default
mode of operation.
~ If buttons one, two. and three are continually activated for more than 1 0
seconds after the rapid blinking starts, the VFD indicator shall be off. When one
of these channels is subsequently activated, the device shall immediately enter
rolling code default mode of operation.
