Introduction
The SmartFob SFR-200 receiver (replaces the SFR-100) detects radio
frequency (RF) signals from the Cansec SmartFob (SFT-200) transmitter.
The receiver comes with two sets of onboard relay contacts, which may be
activated via a DIP switch. A Cansec SmartFob transmitter will cause the
relay contacts to toggle on and off for approximately one second. A typical
use for these relay contacts is to turn on a indicator light to let users know
when data from SmartFob transmitters is received and decoded correctly.
After the receiver decodes the RF signal from the transmitter, it will output
Wiegand data to an access controller. The Cansec SFT-200 transmitter has
two buttons:
•Button I
•Button II
The SFR-200 receiver may be configured via a DIP switch to operate in:
•Common Mode - data from Button I and II is sent via AD0 and AD1
•Split Mode - data from Button I is sent via AD0 and AD1, and data
from Button II is sent via BD0 and BD1
A typical example of the split mode of operation is IN / OUT functionality
for two-door garage applications.
•increased signal reception range
•better noise filtering (at 315 MHz)
•standard 26-bit or Cansec 37-bit Wiegand output to an access controller
•interchangeable with existing SFR100 receivers
•audible indicators help with troubleshooting
•RSSI signal indicates RF interference to aid in proper receiver placement

JUMPER 2 OUT = Accepts SF200 Transmitters only (binary stream support)
IN = Accepts SFR100 or SFR200 transmitters (SF100 Mode)
JUMPER 3 N/A = Reserved for future use.

JP1 AND LED1
C: RECEIVED SIGNAL STRENGTH INDICATION (RSSI) ADJUSTMENT
(Top 2 pins) = RSSI is OFF (default position maximum sensitivity and
range).
(Bottom 2 pins) = RSSI is ON. Carefully adjust for range. For noise
rejection set VR1 just below the point that causes LED1 to turn off.
NOTE: will be constantly flashing if unit is at maximum sensitivity or if
is set to Maximum Range.
It is best to operate the SFR-200 is with the RSSI jumper set to OFF (receiver
is set to its maximum receive range).

HOW TO REDUCE RANGE
To reduce the receive range, set the RSSI jumper to ON and adjust VR1 to
the required reduced range. The procedure is as follows:
1. Adjust VR1 position to the point where the LED1 just turns off.
NOTE: To aid in this adjustment the SFR-200 Receiver's audible beep
can be used. Each time a Cansec SmartFob transmitter is decoded
correctly the SFR-200 receiver will beep.
2. Adjust VR1 toward the (-) or reduced range.
3. Back away from the receiver and press the SmartFob transmitter. If no
audible beep is heard, the range has been exceeded.
4. Repeat this procedure until the required range is found.
NOTE: It is important to test more than one SmartFob transmitter to verify
this reduced range. It is also important to test the area of reception from all
different angles to the SFR-200 receiver.

DIP SWITCH S1, WIEGAND OUTPUT AND POWER INPUT

D: DIP SWITCH
= Default position: Switch 1, 2, and 3 OFF; switch 4 ON
Switch 1
OFF = Common Mode.
Buttons I and II on the SmartFob transmitter will send data via
AD0 and AD1 and activate relay 1 if relay activation is on
ON = Split Mode.
Button I will send data via AD0 and AD1 and activate relay 1*
Button II will send data via BD0 and BD1 and activate relay 2*
Switch 2
OFF = A single valid data bundle is received and then Wiegand data is
sent to the access controller. See the DIP Switch 2
note below.
ON = Receiver will read and validate and compare two successive data
bundles. If they are the same, then Wiegand data is sent to the
access controller. See the DIP Switch 2
note below.
Switch 3 OFF = 37-bit Cansec propriety Wiegand.
ON = 26-bit standard Wiegand.
Switch 4 OFF = Relay activation off.
ON = Relay activation on.
DIP Switch 2: In extremely noisy areas, some random Wiegand data may
pass the decoding tests and produce an invalid number to the access control
panel. Enabling DIP switch 2 will eliminate the problem.

F: WIEGAND OUTPUT G: POWER INPUT
See section (D) Dip Switch for information on split and common Wiegand data

Measuring RSSI Voltage
To measure the receiver module RSSI voltage:
1. Set a voltmeter to DC volts and 5 volt range
2. Connect the voltmeter between VOLT (+) lead and GND ( - ) lead.
This voltage measurement indicates direct ambient RF noise; it is not
affected by the VR1 RSSI control circuitry. A lower voltage means less
ambient RF noise. A higher voltage means more ambient RF noise. This
directly affects reception distance and quality.
RF NOISE
RF noise reception affects range and signal readability, the lower the RSSI
voltage the better quality of signal is being received. The SFR-200 receiver
module has more filtering and better range, but it has its limitations in
certain environments.
Typical Office Area Average RSSI Voltage
no antenna 0.4V
with antenna 0.55V to 0.6V
A reading in the 1V range means that there is a high level of ambient RF
noise at the receiver. You may have to move the receiver away from the
source of the noise.
When measuring the RSSI voltage, if you activate a SmartFob transmitter by
pressing one of the buttons, the voltage will jump to the 1V range. This is an
indicator of the strength of the RF transmission signal relative to the
ambient RF noise.

DIPOLE VS VERTICAL ANTENNAE
Dipole antennae should used to improve range and signal quality. This is
because vertical antennae receive RF signals from all directions, while dipole
antennae receive most RF signals from the front and back, eliminating noise
from the sides of the antenna.
Mounting Recommendations
1. Mount the receiver as shown at the bottom. This will put the vertical
antenna in a horizontal position, which achieves the best range for the
Cansec SmartFob transmitter.
2. Mount the receiver in a low electrical interference location.
3. Mount the receiver in a location which optimizes a line of sight from the
transmitter.
4. Vertical Antenna: When using a vertical antenna, mount the SFR-200
receiver housing about 9 in (25 cm) away from the wall surface.
5. Dipole Antenna: The dipole antenna comes with an L-bracket for
proper antenna mounting. Connect a short piece (less than 25 ft or 8 m)
of 75 ohm coax (CATV cable and connectors) to the antenna and place
the receiver in a suitable location.
