TriggerPad
TP -100/105
DESCRIPTION:______________________________
Rugged wireless remote
control is within reach.
Matric’s TriggerPad family
of handheld transmitters
are ideal for many
material handling and
process control
applications such as jib
cranes, sifting grates,
slurry barges, and belt
controls.
TriggerPad handhelds are pocket sized operator control stations that
provide long switch life, one hand operation, and extended battery life.
With a typical range of 300 feet and a rugged molded enclosure, the
TriggerPad is right at home on the plant floor, in a quarry, or in your tool
belt.
Consult our online catalog for the latest models and features in the
TriggerPad family of handheld transmitters.
FEATURES:_________________________________
• Sealed handheld enclosure
• Range of 300 feet
• License free radio (FCC Part 15B)
• One month battery life (typical)
• 1 million cycle sealed pushbuttons
• Easy one hand operation
• Custom labeling available
APPLICATION:______________________________
Please Note: The TriggerPad 100/105 is not intended for use as
an emergency stop device.
The TriggerPad 100/105 is a transmit on command device. Data is
transmitted from the TriggerPad only when a button is being pressed by
an operator. CRC data error checking and data message identifiers are
used to insure that transmitted data is correctly received and
interpreted. The transmit on demand feature results in extended battery
life (up to 1 month in most applications). However, without a
continuously maintained communication link, the TriggerPad is not
appropriate for applications that require a handheld shutdown for
emergency or safety purposes.
A system level risk assessment should be performed before any new
control application is installed.

CONFIGURATION:____________________________
Label
There are several standard label configurations available for the
TriggerPad, each geared to a typical TriggerPad application. If your
application requires a unique label, our engineering staff can create a
custom label according to your specifications. Please refer to the
TriggerPad configuration sheet to select an off- the-shelf label or to
specify a custom label.
Radio Channel Configuration
The TriggerPad supports eight channels to avoid interaction when
multiple systems are employed in close proximity situations. The radio
channel can be configured at the factory prior to shipment or by a
customer’s technician in the field. See the configuration sheet to specify
a channel for factory configuration.
Channel Frequency
0 903.37 MHz
1* 906.37 MHz*
2 907.87 MHz
3 909.37 MHz
4 912.37 MHz
5 915.37 MHz
6 919.87 MHz
7 921.37 MHz
*Factory default channel selection
For safety reasons, on site radio channel configuration requires the
following basic steps.
1. Power down and lock out any systems that could be operating at
the frequencies shown above.
2. Set the TriggerPad channel. (See instructions below.)
3. Set the channel of the ProComm. (Refer to the appropriate
receiver user manual, i.e. ProComm 100, for receiver
configuration.)
4. Return processes and equipment to service.
Please note, to avoid accidentally duplicating channels, it is
recommended that the default channel NOT be used in a multi-station
application.
The following procedure will select the appropriate TriggerPad channel
for use with any applicable Matric receiver.
1. Disconnect the associated reciever from power and field wiring.
Also, disable any other devices that could be inadvertently
activated by the TriggerPad during this process.
2. Remove the four corner screws and open the back of the
TriggerPad. See diagram below.

3. Remove batteries.
4. Install channel setting link to position A as shown below.

5. Install batteries. Note polarity on circuit board under batteries.
6. The current channel will be displayed on the LED indicators on
the front of the TriggerPad. Press and release the top button to
cycle through channels until the desired channel is displayed.
See the diagram below to interpret channel numbers.
Channel 0 Channel 1 Channel 2 Channel 3
Channel 4 Channel 5 Channel 6 Channel 7
7. Remove the channel setting link and replace the cover. The
TriggerPad is now ready for operation.
INDICATORS:________ _______________________
The TriggerPad 100 provides 4 red LED indicators. One LED is located
beside each button. These LEDs serve three functions.
First, the LED next to a button will be illuminated when the button is
depressed. This is hardwired visual feedback that the button has been
activated. However, the active button indicator does not show the
status of data transmission.
Second, when no buttons are depressed, the top LED will blink to
indicate a low battery condition.
Third, the LEDs are used to indicate the selected channel. See the
configuration section for details of channel selection.
The TriggerPad 105 provides a two digit seven segment LED display.
This display is used to set the one byte value that is transmitted with the
switch status from the TP- 105. To change the value, press the “Enter”
switch while pressing either the up or down arrow.
BATTERIES:________________________________
The TriggerPad 100/105 uses three standard AA batteries. Depending
upon usage, these batteries should provide up to one month of
operation. A low battery power state will be indicated by a blinking LED
as described in the indicator section.
To replace batteries, simply remove the four corner screws, open the
back half of the enclosure, replace the batteries, and reassemble the
enclosure. The correct battery polarity is marked under the battery clips.
PLACEMENT:________________________________
The TriggerPad 100/105 is an FSK radio transmitter that operates in the
902-928 MHz band. Eight channels are provided for separation in
adjacent applications. Multiple transmitters may be active on separate
channels so long as an adjacent channel’s signal does not enter the
receiver at a level exceeding the rejection capability of the receiver. The
effective rejection capability of the receiver is dependent upon RF factors
that vary from application to application. The rejection capability in a
particular application may be determined through trial and error or
through a comprehensive site assessment.
A site assessment should be performed before any new radio system is
introduced into an operating environment where there are potential
safety hazards. A thorough site assessment of an area will discover
active radio frequencies that could lead to contention and their sources.
Matric can arrange a site assessment at a customer’s request.
For optimal performance, the TriggerPad should be operated in the most
visible line of sight from the receiver antenna.
APPROVALS:________________________________
The TP-100/105 has been tested and found to comply with the limits for
an intentional radiating device, pursuant to Part 15 of the United States
FCC Rules. Changes or modifications not expressly approved by Matric
could void the user’s authority to operate the TP-100/105.
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.
