NO OEM LINX REMOTE CONTROL OR FUNCTION MODULE
SHOULD EVER BE USED IN LIFE AND PROPERTY SAFETY
SITUATIONS. No OEM Linx Remote Control or Function Module
should be modified for Life and Property Safety Situations. Such
modification cannot provide sufficient safety and will void the product’s
regulatory certification and warranty.
Customers may use our (non-Function) Modules, Antenna and
Connectors as part of other systems in Life Safety Situations, but
only with necessary and industry appropriate redundancies and
in compliance with applicable safety standards, including without
limitation, ANSI and NFPA standards. It is solely the responsibility
of any Linx customer who uses one or more of these products to
incorporate appropriate redundancies and safety standards for the Life
and Property Safety Situation application.
Do not use this or any Linx product to trigger an action directly
from the data line or RSSI lines without a protocol or encoder/
decoder to validate the data. Without validation, any signal from
another unrelated transmitter in the environment received by the module
could inadvertently trigger the action.
All RF products are susceptible to RF interference that can prevent
communication. RF products without frequency agility or hopping
implemented are more subject to interference. This module does not
have a frequency hopping protocol built in.
Do not use any Linx product over the limits in this data guide.
Excessive voltage or extended operation at the maximum voltage could
cause product failure. Exceeding the reflow temperature profile could
cause product failure which is not immediately evident.
Do not make any physical or electrical modifications to any Linx
product. This will void the warranty and regulatory and UL certifications
and may cause product failure which is not immediately evident.

Theory of Operation
The OTX-868-HH-LR8-PRC Long-Range Handheld Transmitter uses
a HumPRCTM Series transceiver to form a simple, yet highly reliable RF
remote control transmitter. The HumPRCTM Series transceiver is a low-cost,
high performance FSK radio that utilizes a proprietary Adaptive Frequency
Agility (AFA) technique and over-the-air protocol. The AFA offers much
greater noise immunity and range than traditional narrow-band transmitters.

When a button is pressed on the transmitter, power is applied to the
internal circuitry and the module is enabled. The module detects the logic
states of the button data lines. These states are formatted into a packet
and transmitted repeatedly until the button is released.

The receiving module checks the addressing in the received packet (and
encryption, if enabled). If the packet is valid and intended for the receiver,
then the module replicates the transmitter's button states on its outputs.
These outputs can then be used to activate whatever external circuitry is
required by the application.

Figure 3: Ordering Information
The transmitter is compatible with the HumPRCTM and HumPROTM
product families. Ranges of up to 0.8 mile (1,300m) are possible with good
antennas and a quiet, line-of-sight environment. Applications operating
over shorter distances also benefit from the increased link reliability and
superior noise immunity provided by the radio and protocol.
Electrical Specifications
By building on the HumPROTM Series data module, it is simple to create
mixed-mode systems that combine data transmissions with remote control
functionality. For example, a single HumPROTM Series transceiver can
accept remote control commands from the handheld transmitter as well as
sensor values from other devices in system. This greatly reduces system
cost and complexity and opens up many options for the creative designer.

Contention Considerations
While it is still possible for interference to interrupt the transmissions, the
HumPRCTM Series minimizes this risk by meeting the Polite Spectrum
Access requirements in the RED standard. Part of this is a Clear Channel
Assessment (CCA). The module briefly listens in on a channel before
it begins a transmission to ensure that there are no other transmitters
currently using the same frequency. If the module detects other RF signals
on the same frequency it will either wait for short random amounts of time
for the other transmission to end or jump to the next channel to make its
transmission.

Battery Replacement
Figure 5 illustrates the relationship between the button locations and
encoder data lines.
The remote unit utilizes a CR2032 lithium button cell. In
normal use with five 2-second activations per day, the
battery provides approximately two years of operation.
To replace the battery, remove the access cover by
pressing firmly on the label area and sliding it off. Once
the unit is open, remove the battery by sliding it from
beneath the holder. Replace it with the same type of
battery while observing the polarity shown in Figure 7.

Figure 7: Battery Access
Joining a Transmitter
The handheld transmitter is associated with a receiver using the built-in
Join Process. This process configures a star network with the central unit
as the system Administrator. Other units are added to the network as
nodes one at a time. Typically, the handheld transmitter is added as a node
to a module that has been configured as an administrator.
Figure 5: Button Assignments
Assembly Diagram
The schematic for a HumPRCTM Series transceiver configured as a receiver
is shown in the Typical Applications section. The transceiver is set as an
Administrator by pressing and holding the PAIR button for 30 seconds.
While the button is held, the MODE_IND line is on. After 30 seconds, the
MODE_IND line repeats a double blink, indicating that the operation has
begun. When the button is released the key and address generation are
complete and the module is an Administrator. A full explanation of this
operation is in the HumPRCTM Series data guide.
The handheld transmitter is joined to an
Administrator by pressing and releasing
the PAIR buttons on both units. The
MODE_IND Window
modules automatically search for each
other using a special protocol. When they
find each other, the administrator sends
the node the encryption key, UMASK
and its network address. The UDESTID
is set to the address of the administrator.
The values are encrypted using a special
factory-defined key. Once the JOIN
PAIR Button
Figure 8: PAIR Button Access
process is complete, the MODE_IND blinks on both units and they now
operate together.

Typical Applications
The signal sent by the PRC Long-Range Handheld
Transmitter can be received by a HumPRCTM
Series transceiver. When a button is pressed
on the transmitter, a corresponding line on the
transceiver goes high. This is then connected to
external circuitry to perform whatever function is
required by the application.

The transmitter and transceiver must first learn
each other's addresses. This is done by taking
the PAIR line high on the transceiver, typically
with a pushbutton switch. At the same time, the PAIR button is pressed
on the back of the transmitter, typically with a paper clip or similar probe.
The MODE_IND line on the transceiver and the LED on the back of the
transmitter begin flashing, indicating that the Pair Process has been
started. The devices automatically find each other and swap addresses.

Figure 10: HumPRCTM Series as a Receiver Schematic
Figure 10 shows a typical schematic for the HumPRCTM Series transceiver
being used as a receiver only. The C0 and C1 lines are pulled to ground,
setting all of the status lines as outputs.
The MODE_IND line is connected to an LED to provide visual feedback to
the user that an action is taking place.
The PAIR line is connected to a pushbutton switch for activating the Join
Process.
The ACK_EN line is pulled to supply so that the module will send an
acknowledgement as soon as it receives a signal. Alternatively, this line can
be connected to external circuitry to take the line high when an action has
taken place. For example, a circuit can take the line high when a motor has
actually stopped or a door has actually locked. This way the LED on the
handheld lights up only when the desired action has occurred.
Additional features can be enabled through the module's Command Data
Interface. The data guide and additional documentation for the HumPRCTM
Series transceiver can be found on the Linx Technologies website at www.
