Theory of Operation
The OTX-900-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 Frequency Hopping
Spread Spectrum (FHSS) technique and over-the-air protocol. The FHSS
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.
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.
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
It is important to understand that even though the transmitter uses a
frequency hopping protocol, it is still possible for interference to interrupt
the transmissions. While the transmitted signal consists of encoded digital
data, only one carrier of any particular frequency can occupy airspace
without contention at any given time. If two transmitters are activated
in the same area at the same time and on the same frequency, then the
signals will interfere with each other and the receiver will not see a valid
transmission, so it will not take any action.
Battery Replacement
The remote unit utilizes a CR2032 lithium button cell. In
normal use with five 2-second activations per day, the
battery provides over 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.

There may be the risk of explosion if the battery is
replaced by the wrong type.

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.
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
MODE_IND Window
units. The 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 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.
Figure 9: Standard (top) and
Pre-certified (bottom) HumPRCTM
Modules
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.
The MODE_IND line and LED flash to indicate that the process was
successful and the devices are ready to use.
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.
linxtechnologies.com.

Operation with the HumPROTM Series
The commands from the handheld transmitter can be received by a
HumPROTM Series transceiver. The transmitter should be joined to the
HumPROTM Series module in the same manner as it would be joined to
a HumPRCTM Series module. The transmitter sends a Remote Activation
command and accepts a Remote Confirm command.
Remote Activation
The transmission output consists of six bytes:
0x03 0x00 0x00 0x00 0x10 <STATUS>
The first byte is 0x03 with the next three bytes 0x00. Byte five is 0x10
which indicates a Remote Activation. Byte six is the STATUS byte, which is
a bit map of the button states. Bit 0 corresponds to button S0 and so forth.
Each bit is 1 if the corresponding line is high. The external microcontroller
connected to the HumPROTM module can read out the header from the
transmission and know which transmitter sent the command. It can then
take whatever action is required by the STATUS bits. Additional information
about reading out the header is available in the HumPROTM Series
Transceiver data guide.
Remote Confirm
The handheld transmitter accepts a Remote Confirm command over the
air to control the LED in the membrane switch. This command has the
following format:
0x00 0x11 <DURATION> <ALIVE>
The first two bytes are 0x00 0x11 and indicate that the packet is a remote
confirm packet.
The DURATION byte indicates the amount of time that the LED should be
held high. This value is multiplied by 10ms. If the value is 0, the LED output
is immediately taken low.
The ALIVE byte indicates how long after the transmission the module
should stay awake in receive mode. This value is multiplied by 0.1s. Once
this duration expires, the module returns to sleep mode.
This message is transmitted to the handheld transmitter’s address. It
must be received by the handheld transmitter within one second of initial

transmission or within the ALIVE interval of the previous Remote Confirm
message.
