MOD190 TRANSCEIVER

DESCRIPTION
The MOD190 is a frequency
hopping spread spectrum
transceiver module designed to
be compatible with US (FCC Part
15.247) and Canadian (RSS-247)
regulations for license free use
in the 900 MHz ISM band. The
MOD190 is designed for mobile
applications in accordance to
Part 2.1091(b).
The MOD190 transceiver is only
integrated into Kar-Tech remote
control products by Kar-Tech, at
Kar-Tech. There are no user
serviceable parts on the
MOD190 transceiver.
The MOD190 is not designed for
multiple antenna applications
and should not be used to
transmit simultaneously with
any other transmitter.
OPERATION
The MOD190 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 MOD190
microcontroller serial port is
connected to the host via
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
MOD190 transceiver contains a
DC regulator which generates a
constant 1.8 VDC for the digital
circuitry. The RF section runs on
the 3.3V supply.

The MOD190 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, 4
7, 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.

INSTALLATION
1)Solder the MOD190
transceiver directly to the
host’s compatible connector.
2)Print and attach the label
as shown below:
3)Place a label on the outside
of the host enclosure in a
visible area. On the label,
include the following:
“Contains Transmitter
Module FCC ID: P4U-
MOD190” and “Contains
Transmitter Module IC:
4534A-MOD190”
4)Connect the appropriate
antenna. Either a ¼
wavelength wire, or a
RPSMA ¼ wavelength
antenna.

Application Requirements:
A)Power the MOD190
Transceiver with 3.3VDC
nominal voltage, with
peak current draw of
750mA.
B)Do not remove the shield
on the MOD190.
C)If you use something other
than the ¼ wave
antenna or the wire
antenna, the unit needs
separate approval.
D)The antenna should be
mounted at least 20cm
from all persons, and
must not transmit
simultaneously with any
other antenna or
transmitter, except in
accordance with FCC
multi transmitter product
procedures.
E)The MOD190 is to be
installed only in mobile
applications. See Part
2.1091 for definitions of
mobile and fixed
applications.
F) Do not operate the
MOD190 without an
antenna.
G)Documentations: In the
host’s User Manual
include the following:
a. That there are no user
serviceable parts in
the radio modules.
They should not
remove or install radio
modules.
b. The “Instructions To
The User” section.
c. The “Industry Canada
Statement”.
d. Include in the manual,
“This device is granted
for use in Mobile only
configurations in
which the antennas
used for this

MOD190 TRANSCEIVER

transmitter must be
installed to provide a
separation distance of
at least 20cm from all
person and not be co-
located with any other
transmitters except in
accordance with FCC
and Industry Canada
multi-transmitter
product procedures.”
BEFORE APPLYING
POWER!
Check power and ground for
proper polarity.
Read the rest of this manual.
TROUBLESHOOTING
There are no user serviceable
