Power Supply Requirements
The module does not have an internal
voltage regulator; therefore it requires a
clean, well-regulated power source. While it
is preferable to power the unit from a battery,
the unit can also be operated from a power
supply as long as noise is less than 20mV.
Power supply noise can significantly
affect the transmitter modulation; therefore,
providing a clean power supply for the
Figure 15: Supply Filter
module should be a high design priority.
A 10-ohm resistor in series with the supply followed by a 10μF tantalum
capacitor from VCC to ground will help in cases where the quality of supply
power is poor. These values may need to be adjusted depending on the
noise present on the supply line.
Transmitting Data
Once a reliable RF link has been established, the challenge becomes how
to effectively transfer data across it. While a properly designed RF link
provides reliable data transfer under most conditions, there are still distinct
differences from a wired link that must be addressed. Since the LC Series
modules do not incorporate internal encoding or decoding, a user has
tremendous flexibility in how data is handled.
If you want to transfer simple control or status signals, such as
button presses or switch closures, and your product does not have a
microprocessor on board, or you wish to avoid protocol development,
consider using an encoder and decoder IC set. These chips are available
from a range of manufacturers, including Linx. They take care of all
encoding and decoding functions and generally provide a number of data
pins to which switches can be directly connected. In addition, address bits
are usually provided for security and to allow the addressing of multiple
units independently. These ICs are an excellent way to bring basic remote
control / status products to market quickly and inexpensively. Additionally, it
is a simple task to interface with inexpensive microprocessors, such as the
Microchip PIC, or one of many IR, remote control, or modem ICs.
It is always important to separate what types of transmissions are
technically possible from those that are legally allowable in the country of
intended operation. While the LR Series is ideally suited to the long range
