PS/2COMB specifically for KTV amplifier control program

In the KTV applications, not only with the remote control device or small computer keyboard to achieve the various operational song, also need power amplifier. TV. 专业 actuators (effects device) were all controlled, especially I Xiegao Dang KTV Geng so. My company has been successively KTV product design follows several proposed control scheme, in all scenarios, Du You I a common characteristic, that is using my original code control technology company, I kind of remote control devices each can be reduced as I a 32-bit device code, the remote control keys for each I can also be reduced to I 16-bit command code, the equipment to achieve the specified control is sending device code and command code, so I to do with the equipment independent, suitable for different types of Amplifier. TV, and even infrared-based remote control of all household appliances. Can be found in common household appliances control Web page of relevant information.

KTV amplifier control is now focused on the latest program, called the PS / 2 COMB, the name suggests, this option is set I PS / 2 devices, but also PS / 2 devices, and common household appliances were control program co-II to I.

PS / 2 interface, along with IBM's PS / 2 computer and announced a new keyboard interface, but also supports the mouse, Beijing Innovation Technology Co., Ltd. open day creatively put forward the expansion I set PS / 2 Society, referred to as EPS2 Agreement (Extended PS / 2 Protocol). I own this extended agreement, combined with our company for many years to promote the use of universal infrared control technology UIR48, then for the specific application in the KTV (KTV-based Application), I kind of KTV amplifier developed. Exciter (effects). TV control scheme, the product called the PS / 2 COMB.

PS/2COMB The main features are as follows:

1, the core component is the size I only 43mmx46mm module, function block diagram and the physical picture shown, there are III a PS/2 socket, are the standard MINI DIN6 standard socket, indicating the PC's PS/2 socket by PS/2 cable access computing PS/2 I (around the electronic matching market sales, both ends DIN6 needles). Two PS/2 座 for socket, which I a socket as a standard PS/2 interface, you can directly access any PS/2 keyboard device, the other holes I Block vary depending on the specific model, or is the standard The PS/2 interface to access any PS/2 keyboard device (00), or access to a dedicated remote control receiver (66 type).

2, both the specific models that have to solve the common problems I were, that is, remote control and any other article I PS / 2 keyboard devices such as small keyboards. Control panel so can be used simultaneously.

3, in addition to III only PS / 2 socket, the other to provide two-way IR control output, infrared launch tube can be directly connected to the amplifier can be achieved on the private dining room. TV and actuators (effects) and other device control.

4, PS/2COMB more important advantage is the control of the infrared device is very flexible, modular on-chip serial memory have I 24C02, using UIR48 technology can modify the memory of the control code to control any type infrared remote control device purpose.

5, because the PS / 2 device itself can provide +5 V power source, no external power supply system, it is simple and easy to use.

PS/2COMB mentioned earlier, there are two forms:

1,00 type: provide two identical PS / 2 interface, you can add any two PS / 2 devices, including remote control receiver (adapter). Ordinary PC keyboard. Small keyboard. Control Panel, etc., the power amplifier control is done through the provision of API in the form of development to achieve II times, meaning that the application for recognition of the need to control hot keys, through the power amplifier PS / 2 interface to send control commands to the module, so the advantage is to control very flexible and can use any models of PS / 2 remote control receiver (adapter) and the corresponding remote control.

2,66 type: offer I a standard PS / 2 interface, you can add any I set PS / 2 devices, including remote control receiver (adapter). Ordinary PC keyboard. A small keyboard. Control Panel, etc., and the other I a PS / 2 interface, although a standard socket, but not actually received the standard PS / 2 device, but external IR receiver head (without decoding) and buzzer (to receive the first and the external auxiliary circuit and buzzer are all installed and the general remote control in the receiver (adapter) in), that the infrared remote control function to achieve PC decoding is accomplished by PS/2COMB module, the module used to intercept the specified remote control button the power amplifier module sent directly through infrared control instructions, no PC software intervention. I come to this advantage is obvious, do not need to access PC software, no programming to do II views the development, brought on the use, inadequate production of the module must be specified when the remote control, remote control amplifier specified hotkey , modules, and since I sold the remote control.

These two types of modules have their own strengths, customers can choose.

Note that, although PS / 2 COMB two way infrared output, but any time I send an infrared signal is like, but, because amplifiers. Exciter (effects) and the TV control code different, do not mutual interference.

Modules will be factory pre-amplifier the most commonly used code, customers can be brought directly. Because the module uses a standard serial memory chips, and memory data structure completely open, I formed the design of an open system. Customers can use the remote control code I provided reading device to read on their own need for the power amplifier module replacement remote control button of the code, according to the corresponding data organization structure, the programmer to write using standard memory chips, can achieve the corresponding control function.

Amplifier module using PS/2COMB involves the following products:

1, PS/2COMB module itself, for every configuration I set rooms, with each module will provide matching infrared emission tube 2;

２，readers: read by the control equipment that amplifier. Exciter (effects) and the TV is equipped with remote control button code, including device code and command codes;

3, Universal Programmer: I did like electronic product development companies are equipped with the basic equipment, but also in terms of this application only supports standard serial memory chips can be, almost all of the programmer has this feature, in other words purchase function for at least the cheapest models I can.。

Customers need to bring their own following accessories:

1, Lotus and infrared control cable plug, plus with the module configuration of the infrared emission control can be put into use;

2, PS / 2 cable, 6DIN structure, both ends of the needle structure is, I side with the module, I side with PC keyboard port.

Here on the PS / 2 COMB - specifically for KTV amplifier control program to do an overview of:

Main advantages:

1. You can also use the keyboard port of the remote control and a small keyboard, the equivalent of PS / 2 shared device;

2. Do not have any remote control Learning remote control function button can allow direct control of any amplifier or TV set, full hardware operation, no computer involved, but does not require user programming;

3. Is not limited to the control amplifier or TV model, using code control technology, code written in the PS / 2 COMB the EEPROM memory can be directly through the PS / 2 mouth configuration program (EPSC, Extended PS / 2 Config) setting any type of control code, and even can rewrite the EEPROM programmer himself directly in the code, completely open;

4. If necessary, can provide the driver (EPSD, Entended PS / 2 Driver), any I a computer keyboard keys information (such as long as the user presses any key I) turn to PS / 2 口 Universal IR control code issued (device code and command code), direct control of the amplifier or TV, KTV application does not require intervention or the need for application re-programming or KTV any changes;

5. If necessary, KTV application can also be directly involved in IR control functions, providing II meeting Developer API, user program can be PS / 2 to PS/2COMB send commands directly control the power amplifier or parameter settings;

6. Whether control computer. Amplifier or TV, remote control can operate only against the computer, the keyboard is so small direct action, do not care about the equipment being controlled on the KTV rooms in what position.

7. Finally I would like to add points, PS / 2 COMB can be used to upgrade existing systems, as long as the previous song device is PS / 2 keyboard port, whether it is remote. Small keyboard or a standard PC keyboard, all direct access to PS / 2 COMB, immediate control of the amplifier and the TV!
