MOD164 TRANSCEIVER
DESCRIPTION
The MOD164 is a frequency
hopping spread spectrum
transceiver module designed to
be compatible with US (FCC Part
15.247) and Canadian (RSS-
210) regulations for license free
use in the 900 MHz ISM band.
The MOD164 is designed for
mobile applications in
accordance to Part 2.1091(b).
OPERATION
The MOD164 is a radio
transceiver module for the 900
MHz ISM bands. The transceiver
microcontroller includes a CPU,
GPI/O, a fully integrated
frequency synthesizer, a power
amplifier, a modulator and a
receiver unit. The MOD164
microcontroller serial port is
connected to the host via
The MOD164 transceiver is only
integrated into Kar-Tech remote
control products by Kar-Tech, at
Kar-Tech. There are no user
serviceable parts on the
MOD164 transceiver.
The MOD164 is not designed for
multiple antenna applications
and should not be used to
transmit simultaneously with
protection circuits. The data is
sent through a serial port to RF
processor and then to RF circuit
to the antenna and the data
received from antenna is sent to
the serial port and to the host.
The microcontroller is
responsible for the control of the
entire communication. The
MOD164 transceiver contains a
DC regulator which generates a
constant 1.8 VDC for the digital
any other transmitter.
circuitry. The RF section runs on
the 3.3V supply.

The MOD164 hops on 50 channel
frequencies that are selected in
a pseudo random order. An
example of the order is:
{48, 25, 17, 20, 41, 37, 36,
10, 15, 44, 30, 6, 42, 33,
5, 8, 28, 1, 23, 49, 16,
3, 19, 29, 21, 43, 31, 9,
18, 27, 22, 45, 13, 2, 32,
11, 14, 46, 12, 24, 4, 7,
38, 47, 35, 40, 50, 34, 39,
26}
where Channel 1 is 902.5 MHZ
and Channel 50 is 927.00 MHZ.
The dwell time of the hopping is
350ms. Each channel is used
equally on average.
The receivers are matched to
the transmitters to use the same
hopping channel sequence and
they hop channels in
synchronization with the
transmitter’s signals.

INSTRUCTION TO THE USER
This equipment has been tested and found to comply with the limits
for a class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates radio frequency energy and if not installed and used in
accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment
does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the
following measures:
* Reorient or relocate the receiving antenna.
* Increase the separation between the equipment and receiver.
* Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
* Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules.
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.
FCC CAUTION: Any changes or modifications not expressly approved
by the party responsible for compliance could void the user's authority
to operate this equipment.

INDUSTRY CANADA STATEMENTS
This device complies with Industry Canada license-exempt RSS
standard(s). Operation is subject to the following two conditions: (1)
this device may not cause interference, and (2) this device must
accept any interference, including interference that may cause
undesired operation of the device.
Le présent appareil est conforme aux CNR d'Industrie Canada
applicables aux appareils radio exempts de licence. L'exploitation est
autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas
produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter
tout brouillage radioélectrique subi, même si le brouillage est
susceptible d'en compromettre le fonctionnement.
Under Industry Canada regulations, this radio transmitter may only
operate using an antenna of a type and maximum (or lesser) gain
approved for the transmitter by Industry Canada. To reduce potential
radio interference to other users, the antenna type and its gain should
be so chosen that the equivalent isotropically radiated power (e.i.r.p.)
is not more than that necessary for successful communication.
Conformément à la réglementation d'Industrie Canada, le présent
émetteur radio peut fonctionner avec une antenne d'un type et d'un
gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie
Canada. Dans le but de réduire les risques de brouillage
radioélectrique à l'intention des autres utilisateurs, il faut choisir le
type d'antenne et son gain de sorte que la puissance isotrope
rayonnée quivalente (p.i.r.e.) ne dépassepas l'intensité nécessaire à
l'établissement d'une communication satisfaisante.

OEM Responsibilities to comply with FCC and Industry Canada
Regulations
The MOD164 Transceiver has been certified for integration into
products only by the OEM integrators under the following conditions:
This device is granted for use in Mobile only configurations per Part
2.1091(b) in which the antennas used must be installed to provide a
separation distance of at least 20cm from all person and not be colocated with any other transmitters except in accordance with FCC and
Industry Canada multi-transmitter product procedures.
As long as the two conditions above are met, further transmitter
testing will not be required. However the OEM integrator is still
responsible for testing their end product for any additional compliance
requirements required with this module installed.
If the above conditions are not met, then the FCC and Industry
Canada authorizations are no longer valid and the FCC ID and IC
Certification Number cannot be used on the final product. In these
cases the OEM integrator is responsible for re-evaluating the end
product and obtaining a separate FCC and Industry Canada
authorization.
Recertification is also needed for all other operating configurations,
including portable configurations with respect to part 2.1093 and
different antenna configurations.
