PC Remote Control
and Code-based Universal Remote Controller
We do ONLY the following remote control
1),PC remote control: remote controller with IR receiver/IR adaptor (special
or normal encoding, the user need not care about the specific coding format);
2),Code-based universal remote controller: one pcb, one IR encoding IC,
produces any IR encoding at any carrier frequency. it can replace any
existing remote control or design 2-in-1 multifunctional remote controller
for example TV/STB comb remote control.
PART ONE: Code-based universal remote
According to the infrared encode chip to distinguish, the remote controller
can be roughly divided into the following three categories:
|1),Standard infrared encoding chip:
such as philips SAA3010(RC5 format), NEC uPD6121/622(nec format) as
orginal chip and many compatible chip.
package: bonding or dip or smt.
change pcb layout wire to define ever key value, an external diode
or resistance to change customer code.
By choosing different coding chip, design different layout to define
each key value.
Application: low cost such as the TV remote control and the AV remote
|2)Pre programmed mask rom chip: usuall for mutli function universal
remote control, included fix coded universal remote control and learning
univerisal remote control.
package: bonding or dip or smt
Using Maskrom MCU to design to store encoded signal via the waveform
capture, this process is called learning.Usually by the end user to
complete, store a key need hundreds of bytes memory space.
The data maybe error and not standard, does not support code hopping,
a key 2 or more codes.
|3),OTP (one time programing) MCU or Flash MCU chip: using mcu (microcontrollers)
to encoding according to the customer's requirments.
package: dip or smt
modify different program,firmware to simulate arbitrary standards
known coding format, such as RC5 or NEC protocal.also can produce
new unknown coding protocol if necessory.
Application: the production of various kinds of known function remote
control alternatives such as projector remote control, multi-function
remote control such as hotel VOD/STB combo controller, multi user
remote controller, the remote computer mouse simulation, code confidential
The cost is relatively high, suitable for every production of 100
to 2000 orders.
Code is stored for each remote control button only needs 4 bytes,
support for EEPROM such as 24C02.
The infrared ray code emitted very accurate and stable
Our company do mainly the OTP(Code-based) remote controller,
Customized PC Remote Control, or OEM
PART TWO: IR receiver or IR adaptor for PC remote control
We can provide infrared receiver (infrared sensor) for the pc,
usually have the following forms:
||1),PS/2 receiver: included PS/2 keyboard and PS/2 mouse,standard
ps/2 device, no drivers.
|2),RS232 reciever: RS232 level,serial port, connected the computer
com (rs232) port directly,Need drivers or provide API (application
||3),USB receiver: USB keyboard and mouse standard device, no drivers
when it been used as a the HID device.
||4),Internal receiver module: TTL level, compatible with RS232 standard,
need drivers or provide API (application program interface), CIR,
I2C or other interface..
||5),Specially designed pc or pc-like equipment, motherboards provide
onboard infrared sensors, so we need not install the infrared receiver.

Customized PC Infrared Receiver.
PART THREE:We can custom all types remote control
including plastic case mould, PCB design and firmware development.We're
standing inventory on the following types of products.
