Features and Controls
RX10K Receiver
The RX10K Receiver features a simple keypad on the front panel
for user configuration and adjustment. A two-line display indicates
the operational status of the RX10K. The RX10K outputs the
signal received from the TX10K-S Transmitter in three ways: 1) as
text and graphics on the display, 2) as an analog voltage signal,
and 3) as a digital data signal.
The top line of the RX10K display indicates the average level of
the transmitted signal in numerical form on the left and in graphical
form on the right (Figure 1). The numeric value corresponds to the
Voltage Output signal in millivolts. For example, an output signal
of +8.450V would be displayed as “+08450”. The bar graph
provides a visual representation of the output signal level. Each
position on the bar graph represents approximately 2V. Both the
numerical and graphical indicators are averages of the received
signal level over a time period of about 0.2 seconds.
Figure 1: Front view of the RX10K
When an operational error is detected, the top line of the display
alternates between the corresponding error code and the actual
signal. See Appendix C for a complete list of error codes.

Located on the RX10K rear panel is the On/Off Power switch, a
jack for 12VDC Power Input, a Fuse housing, a connector for
attaching the Receiver Antenna, binding posts for the analog
Voltage Output, and a Com (DB9) connector for the digital data
signal. The analog Voltage Output signal has a nominal range of
±10VDC and a maximum range of ±12VDC. The digital data
signal is an RS-232 type signal for input to a PC “Com” port. See
Appendix A for the pin out and protocol.
Figure 2: Rear panel of the RX10K
CAUTION: The Power Input, Voltage Output and Com (digital
output) share a common (or ground) connection. Specifically, the
outside ring of the Power Input, the “-“ jack of the Voltage Output
and pin 5 of the Com output are all internally connected.
Care must be taken in connecting the RX10K to external
components in order to eliminate ground loop problems. Such
ground loop currents can cause errors in the output signals and
possible internal damage.
The included power supply is electrically isolated and will eliminate
any ground loop problems with the Power Input. It is
recommended that the Com (digital output) and Analog Output are
not connected to external equipment at the same time. An
exception to this rule exists when one of the two external devices
accepting the analog or digital output signal is “floating” or not
externally connected, such as battery operated voltmeter or a
laptop powered by batteries.

User Parameter Selection and Adjustment
The RX10K Receiver has seven user-configurable parameters.
The parameter name and value are shown on the lower line of the
display. Parameters are selected by scrolling through the
parameter menu using the SELECT ◄► (left and right) arrow
keys. The value of that parameter is adjusted using the ADJUST
▲▼ (up and down) arrow keys. The parameter name is displayed
on the left side and the value on the right. A description of the
parameter screens and possible settings follow.
Channel
The Channel parameter allows the user to change the receiving
RF channel to match the RF channel of the TX10K-S. There are
16 RF channels. Appendix A contains a table listing the RF
channels and their corresponding frequencies. Along with the
channel selection value, a bar graph indicating the relative RF
signal strength being received is displayed. The more “=” units,
the better the signal strength (ten is maximum).
Input
The Input parameter allows the user to simulate certain inputs
from the TX10K-S. These can be used to check the operation and
settings of the RX10K, even without a transmitter. The possible
values are listed below:
Input Description
Transmitter The TX10K-S signal is the input (normal operating
mode)
+FS Positive Full Scale input is simulated
Zero Zero level signal input is simulated
-FS Negative Full Scale input is simulated
+FS/2 Positive half scale input is simulated
-FS/2 Negative half scale input is simulated
+FS/4 Positive quarter scale input is simulated
-FS/4 Negative quarter scale input is simulated

Binsfeld Engineering Inc. | 231-334-4383 www.binsfeld.com 869500-9_G Pg. 7
Filter
The Filter parameter allows the user to change the bandwidth of
the output signal. It functions as a low pass filter, meaning
frequencies above the selected value are attenuated. This allows
the user to reduce the amount of high frequency data on the
output signal (i.e., reduce noise) and effectively average the output
value. Selectable values are 500, 250, 120, 60, 30, 15, 8, 4, 1 Hz.
NOTE: Changing the Filter settings also changes the reception
error rate detection threshold. This means that using a lower Filter
setting may improve data integrity in an electrically noisy
environment (where RF interference is present).
Input AutoZero
The Input AutoZero parameter provides an easy way to
compensate the output for any offset from the gage or sensor.
When turned On ("Input AutoZero: On"), the existing input from the
TX10K-S becomes the input zero. Before adjusting the Gain,
apply the AutoZero to the input signal. In this way, the zero (0V)
output will not change when the Gain setting is adjusted. When
the AutoZero is off ("Input AutoZero: Off"), no offset correction is
applied to the output signal.
To turn the AutoZero On, press and hold the ADJUST ▲key for 2
seconds. To turn the AutoZero Off, press and hold the ADJUST
▼key for 2 seconds. In order for AutoZero to properly zero the
output, the displayed output number must be stable. Switching the
Filter to a lower frequency setting may help stabilize the signal to
enable an effective AutoZero. The Filter may then be returned to
its original setting for normal operation. The AutoZero function will
not work properly if there are 1) too many “TxRx Data” errors, 2)
the signal from the TX10K-S is over or under range, or 3) the Input
parameter is not set to “Transmitter”.

Polarity
The Polarity parameter allows the user to change the polarity of
the output signal.
Gain
The Gain parameter allows the user to adjust the gain or scale
factor applied to the input signal and is reflected in the display
output, the Voltage Output signal, and the digital (RS-232) output
signal. The Transmitter Gain is displayed on the left ("Gain
T:02000 S:02000") and is changed using the RM10K Remote
Control. The System Gain is shown on the right ("Gain T:02000
S:02000") and is the parameter adjusted on the RX10K.
The Transmitter Gain is set based on the microstrain (e) range
expected during a given test (see table below; strain values
assume a Gage Factor of 2.0).

Full Scale Strain corresponds to a display reading of 10000, an
analog Voltage Output value of 10 VDC, and a digital data output
of 10000. The System Gain can be adjusted from 25% to 400% of
the Transmitter Gain (i.e., ¼ to 4 times the Transmitter Gain) for
convenient output scaling. The equation below relates strain input
to Voltage Output.

The Transmitter Excitation Voltage (VEXC) to the gage is 2.5 VDC.
The Gage Factor is specified by the gage manufacturer but is
typically about 2.0. See Appendix B for Full Scale torque and
output scaling equations and sample calculations.
Output Offset
The Output Offset allows the user to adjust the offset or “move the
zero” of the output from the RX10K. The adjustment value
displayed on the right is the actual output offset value in millivolts.
The adjustment range is from –12000mV to +12000mV (12V),
meaning the zero can be moved anywhere within the output
range.
This adjustment affects the display output, the Voltage Output
signal, and the digital (RS-232) output signal. The Output Offset
value is applied to the signal after the Gain adjustment; therefore,
the Gain adjustment may affect the zero output signal.
User Default
The RX10K parameters can be returned to their default settings.
Holding down the ADJUST ▲key while powering up the RX10K
resets the RX10K to the default values listed below.

Signal Processing
The TX10K-S data signal is processed by the RX10K as follows:
1. Receive signal from TX10K-S
2. Check for errors and display if any detected
3. Check for simulated signal and apply if enabled
4. Apply Filter
5. Apply AutoZero
6. Apply Polarity
7. Apply Gain
8. Apply Output Offset
9. Send signal to display, voltage output, and digital output
TX10K-S Transmitter
The TX10K-S Transmitter is encased in a tough nylon housing
with a V-groove on the bottom for improved shaft alignment and
an indentation on the top to guide fiberglass reinforced strapping
tape installation. The TX10K-S also features a Status Indicator
light, an Infrared Receiver lens, a Transmitter Antenna connector,
and a screw terminal block for making power and sensor input
connections.

Binsfeld Engineering Inc. | 231-334-4383 www.binsfeld.com 869500-9_G Pg. 11
The TX10K-S can be configured even while it is installed (but not
rotating) using the RM10K Remote Control. The TX10K-S has
sixteen RF Channel settings and six Gain settings (500, 1000,
2000, 4000, 8000, and 16000). It can send low and high
reference signals to the RX10K: internal precision shunt resistors
simulate strain values that can be used to check calibration (refer
to Appendix A for specifications).
NOTE: Make certain the Infrared Receiver lens remains
unobstructed so that data can be received from the RM10K
Remote Control.
Status Indicator Light
When the TX10K-S is powered up, it cycles through a startup
sequence. It transmits four reference signals (the low and high
strain values, positive and negative) and the green Status
Indicator light on the TX10K-S flashes. Once the Status Indicator
is on solid, it is in normal operating mode (transmitting actual data
from the sensor). An error is indicated when the light is flashing,
flickering or off as described below.
Indication TX10K-S Status
Off continuously No power applied; power polarity
is reversed; battery is dead; or the
transmitter is in Standby mode.
One flash off for ½ second A Gain or Channel command has
been received from the RM10K
Remote Control.
Another flash off for ½ second The Gain or Channel command
has been carried out.
NOTE: If there is only one flash
when changing Gain or Channel,
then the high or low limit has
been reached and cannot change
any further in that direction.

Binsfeld Engineering Inc. | 231-334-4383 www.binsfeld.com 869500-9_G Pg. 12
Fast flash (7 Hz) The input signal to the TX10K-S
is out of range. Reducing the
Gain will increase the input range
and may eliminate this problem.
NOTE: If the out-of-range
condition is of a short duration,
there may only be one or two
flashes.
Slow flash (2 Hz) One of the References (shunts) is
enabled. NOTE: If a signal out of
range condition occurs while the
Reference is enabled, the light
will indicate the out of range
condition (fast flash).
Flicker off once every second The power input voltage is either
too high or too low. NOTE:
Improper operation or damage to
the transmitter can occur if
operated outside its specified
power input voltage range.
RM10K Remote Control
The handheld RM10K Remote Control allows the user to configure
the TX10K-S Transmitter even while it is installed. The RM10K
keypad operates similar to a common TV remote control, emitting
an infrared signal through the window on the front of the unit.
Simply point the RM10K at the Infrared Receiver on the TX10K-S
and press the proper key to change the configuration. Both the
Infrared Receiver lens and the window on the front of the RM10K
need to be kept clean in order to function properly.
NOTE: The RM10K is designed to transmit commands to the
transmitter when it is stationary. It will work at slow rotation
speeds, typically less than 100 rpm.

Figure 4: RM10K Remote Control
Battery Installation
Slide the battery access cover on the back of the RM10K
enclosure in the direction of the arrow to open. Remove the old
battery if present. Install a new 9V battery and slide the cover
back into place.
Operational Distance Settings
Typically, the RM10K needs to be within 6 inches (150 mm) of the
TX10K-S for the signal to be received. This normal (low infrared
power) mode is intended to reduce the possibility of inadvertently
changing the configuration of the TX10K-S by accidentally
pressing a key on the RM10K. It also reduces the chance of
changing the configuration of other transmitters in a multiple-
transmitter installation.
The RM10K also has a high infrared power mode. This mode is
useful when access to the TX10K-S is difficult or dangerous. Line-
of-sight distances of 20 feet (6 meters) or more are feasible. The
infrared signal will reflect off bright or shiny surfaces, making non-
line-of-sight operation possible in some situations.
To enable the high infrared power mode, first press and release
the TRANSMITTER ON key and then press the desired function
key. When the TRANSMITTER ON key is pressed, the green
SENDING light on the RM10K will come on for about 3 seconds.
The desired function key must be pressed within this 3-second

Binsfeld Engineering Inc. | 231-334-4383 www.binsfeld.com 869500-9_G Pg. 14
timeframe; otherwise the RM10K will revert back to normal (low
infrared power) mode. To send the ON command in high power
mode, press the TRANSMITTER ON key twice.
The Infrared Receiver on the TX10K-S has an automatic gain
control. Under bright light, it will become less sensitive, and the
operational distance will be decreased. If the TX10K-S is not
receiving commands from the RM10K, try shading the Infrared
Receiver from direct, bright light.
RM10K Key Functions
A summary of each of the RM10K key functions and indicator light
operation appears below.
TRANSMITTER ON
Brings the TX10K-S out of Standby mode or temporarily enables
high infrared power mode.
TRANSMITTER STANDBY
Switches the TX10K-S into a low-power Standby mode to
conserve the battery. No signal is transmitted while in Standby
mode. The Status Indicator light on the TX10K-S turns off. The
TX10K-S ignores all commands from the RM10K except
TRANSMITTER ON. Disconnecting and reconnecting the 9V
battery or activating TRANSMITTER ON brings the TX10K-S out
of Standby mode.
REFERENCE 1
Activates the Reference 1 input signal or shunt resistor on the
TX10K-S for 5 seconds. With a 350Ωgage and 2.0 gage factor,
the value simulates input strain equivalent to 100 microstrain in the
positive direction. If this key is held down, the Reference will stay
activated. If the key is pressed again within the 5 seconds, the
Reference will remain activated for another 5 seconds (see
Appendix A.)
REFERENCE 2
Operation is the same as Reference 1 but simulates a 500
microstrain input in the positive direction with a 350Ωgage and 2.0
Gage Factor (see Appendix A).

Binsfeld Engineering Inc. | 231-334-4383 www.binsfeld.com 869500-9_G Pg. 15
GAIN ▲
Increases the gain setting of the TX10K-S. If the Transmitter Gain
is already at the maximum value, the Status Indicator on the
TX10K-S will flash only once, indicating the command was
received but not carried out.
GAIN ▼
Decreases the gain setting of the TX10K-S. If the gain is already
at the minimum value, the Status Indicator on the TX10K-S will
flash only once, indicating the command was received but not
carried out.
CHANNEL ▲
Increases the RF channel of the TX10K-S. If the channel is
already at the maximum value, the Status Indicator on the TX10K-
S will flash only once, indicating the command was received but
not carried out.
CHANNEL ▼
Decreases the RF channel of the TX10K-S. If the channel is
already at the minimum value, the Status Indicator on the TX10K-
S will flash only once, indicating the command was received but
not carried out.
SENDING Light
The SENDING light will come on for about 1 second when a key is
pressed. This indicates the RM10K is sending a signal. It is not
an indication that the TX10K-S has received the signal. The
Status Indicator on the TX10K-S or the display on the RX10K can
be monitored to confirm successful command transmission.
If the SENDING light flashes after a key is pressed, the battery in
the RM10K is low and should be replaced. If the SENDING light
does not come on at all after a key is pressed, the battery is dead
and needs to be replaced.
As mentioned in the previous section, the SENDING light will stay
on for about 3 seconds after the TRANSMITTER ON key has
been pressed. This indicates the RM10K is in high power mode,
and any command sent during the next 3 seconds will be at the
high infrared power level.

Binsfeld Engineering Inc. | 231-334-4383 www.binsfeld.com 869500-9_G Pg. 16
Multiple TX10K-S Transmitters
When working with multiple TX10K-S Transmitters in close
proximity, the Infrared Receivers may be intentionally covered with
an opaque object in order to eliminate an inadvertent configuration
change to an adjacent TX10K-S. Also, removing power
(disconnecting the battery) or putting the TX10K-S in standby
mode will prevent the RM10K from changing the configuration of a
transmitter.
Product Safety
The user assumes all risk and liability for the installation and
operation of this equipment. Each application presents its own
hazards. Typically, certain system components are strapped to a
rotating shaft. If sufficient care is not taken to properly secure
these components or accessories connected to them, they can be
flung from the shaft, causing damage to the components or to
property or persons in the vicinity. Use more than enough tape:
10 or more wraps is not too much.
Installation Procedure
The TorqueTrak 10K System is designed for ease of use. The
procedure for a typical setup on a shaft for obtaining torque
measurements is detailed in the Field Testing section below.
It is recommended that the user bench test the instrument to
become familiar with the various operational features prior to
conducting tests in the field. The BS900 Bridge Simulator and 9V
Battery Connector have been provided for this purpose. See the
Bench Testing section for details.

Binsfeld Engineering Inc. | 231-334-4383 www.binsfeld.com 869500-9_G Pg. 17
Field Testing
Although the settings of the TX10K-S can be changed during
operation of the system, it is best to determine the appropriate
Transmitter Gain setting for a given application prior to installation.
Refer to Appendix B for the relevant calculations.
1. Attach sensor or strain gage to the shaft (or other surface)
where the desired strain will be measured. Refer to Appendix
D for instructions on strain gage application.
2. Remove cover from BH10K Battery Housing. Snap fresh 9V
battery onto snaps and place into BH10K. Secure cover with
screws with re-usable vibration-resistant coating. Make sure
that the cover and screws are tightly fastened.
NOTE: The BH10K is most useful when testing extends
beyond the life of the battery, allowing replacement without
removal from the shaft. Alternatively, the 9V Battery
Connector can be used. In this case, skip step 4.
3. Screw Transmitter Antenna onto TX10K-S Transmitter.
Secure TX10K-S and BH10K (or battery) to shaft using
fiberglass reinforced strapping tape. Align V-groove on
bottom axially with shaft and tape across indentation in top.
Do not cover TX10K-S Infrared Receiver or Status Indicator.
Alternatively, hose clamps, machined collars, or other
mounting devices may be used but avoid excessive
compression.
CAUTION: Be certain all components are fixed firmly to
moving surfaces. The Transmitter and battery holder have a
groove for the fiberglass reinforced fiberglass reinforced
strapping tape, which should be wrapped around at least 10
times (5 times in each direction) to secure the components to
the shaft. The open end of the tape should follow shaft
rotation. For extra protection, glue the end of the tape down.
When finished with testing cut the tape and remove
components. Avoid the risk of being struck by improperly
secured objects flung from the machine by standing clear
during operation!
NOTE 1: This method of securing the transmitter and battery
holder is for temporary use only. For long term use this tape
should be examined frequently for the effects of environmental
influences (e.g.: excessive oils) or extreme conditions (e.g.:

Binsfeld Engineering Inc. | 231-334-4383 www.binsfeld.com 869500-9_G Pg. 18
rapid starts/stops, high temperatures). Replace tape as
required following the notes in the “CAUTION” previously
listed.
NOTE 2: If the shaft is small (≤1” or 25 mm), balance might
be an issue. In this case, steps may have to be taken to
balance the transmitter (TX10K) and the battery and housing
(BH10K). Please discuss this with your Binsfeld Engineering
Sales Representative.
4. Cut an appropriate length of 2-conductor power cable (red &
black twisted pair) and strip and tin ends. Connect red wire to
+B on BH10K and to +B on TX10K-S and black wire to -B on
BH10K and to -B on TX10K-S. The Status Indicator light
should blink several times and then come on solid. Secure to
shaft.
NOTE: If testing will not begin for some time, use the RM10K
Remote Control to put the TX10K-S in Standby mode to save
battery life. The Status Indicator light will turn off. A fresh
battery will last for several days in this mode.
5. Cut an appropriate length of 4-conductor ribbon cable (as
short as practical to avoid unwanted electrical noise) and strip
and tin ends. Solder to gage per Appendix D or gage
manufacturer’s specification and make appropriate
connections to the TX10K-S terminals. Secure loose cable to
shaft.
6. Connect Receiver Antenna to Antenna connector on the rear
panel of the RX10K Receiver. Position magnetic-mount
antenna with element installed near the TX10K-S, typically
within 10 feet (3 meters).
7. Insert connector on AC/DC adapter into Power Input jack on
the RX10K rear panel. Plug adapter into appropriate AC
power source (i.e., wall socket). Flip the RX10K power switch
to On while holding down the ADJUST ▲key.
NOTE: This resets the RX10K parameters to their default
settings. Simply turn On without holding any keys if previously
set parameter configurations are desired.
8. Turn on the TX10K-S with the RM10K (if needed). Confirm
that Status Indicator light is on solid. Slowly scroll through
each RX10K channel until it matches TX10K-S channel setting
(top line will quit flashing and bottom line will show the RF

Binsfeld Engineering Inc. | 231-334-4383 www.binsfeld.com 869500-9_G Pg. 19
signal strength). Change both units to desired channel and
verify adequate signal strength. If possible, rotate the TX10K-
S through complete range of motion to verify strong signal
reception in all orientations.
9. Scroll RX10K display to Gain parameter screen. Use the
RM10K to configure the Transmitter Gain to the appropriate
level.
10. Scroll RX10K display to Input AutoZero parameter screen.
Apply AutoZero with no load on the shaft to zero-out any initial
gage offset. Press and hold ADJUST ▲key for 2 seconds
until bottom line reads “Input AutoZero: On”. AutoZero can be
reset by turning off and then on again.
NOTE: Once AutoZero is activated, the initial gage offset is
subtracted from the output, which has a maximum range of
±12 V. The extra ±2 V overhead above and below Full Scale
(±10 V) is provided to help minimize this reduction in range.
For example, if the initial offset is 1.6 V, then the maximum
output of the system will be 10.4 V after AutoZero is set. This
still allows for strain measurement up to Full Scale.
If before activating AutoZero there is an initial offset of more
than 50% of Full Scale, it may be necessary to 1) use a lower
Transmitter Gain setting, 2) apply a shunt resistor to balance
the gage, or 3) replace the strain gage. For further

11. Scroll RX10K display to Filter parameter screen. Set the Filter
to the desired level.
12. Scroll RX10K display to Gain parameter screen. Set the
System Gain to scale and/or calibrate output based on
calculations as demonstrated in Appendix B. Check
calibration by using the RM10K to command the TX10K-S to
transmit REFERENCE 1 and/or 2to the RX10K.
13. Connect appropriate recording device to either the analog
Voltage Output terminals or digital Com (DB9) connector.
Check the zero and adjust using the Output Offset if needed.
14. The system is now ready to record data.
