AV-type appliance controller

UIR that means Universal Infrared Control, Beijing Innovation Technology Co., Ltd. Tiankai years of painstaking research of infrared remote control technology, to develop a common set of infrared control technology, with 48-bit binary number that is six bytes can express arbitrary waveform infrared control, said for the UIR48 standards, is innovative enterprise standards. This standard is actually composed of two aspects of meaning, one of the arbitrary control of off-the-shelf code for how to use the expression of this six-byte code? Second, the designated six-byte encoding UIR48 how accurately reproduce the original waveform of the IR control? In short, it is UIR48 how the problem of encoding and decoding.

For the applications, only the relationship between the original remote used by the various key coding accuracy, which is to replace the remote control to achieve the same essential purpose, that is the need for a reading device that can read a variety of different types of remote control codes.

Will be a variety of different types of remote control button to read out the code, you can fill in the form of a specific control code table or code for the programming of these parameters in the infrared control to calling application. Therefore, for any user, UIR48 a set of equipment is essential reading, and reading with a control device itself can be a timely verification of code used to read out the target device can control, so greatly facilitate a common infrared control technology and the promotion of the universal.

Reading early equipment into the ISA slot-type, there are three functions: 1, reading, running getcode.exe software, will need to replace the remote control at the infra-red reading device to receive the first button click, reading software can be immediately reported to the remote control device of the 4-byte code DeviceCode and 2-byte command code CommandCode; 2, PC remote control, with 2 / 3 type remote control, remote control driver can run a set of PC-style ISA add-in card remote control; 3, appliance control, the secondary development of the use of API do send data to the card, the card configuration on the infrared emission of the tube can be read is encoded in the infrared signal control equipment specified, the package provided procedures to control the presentation putcode.exe, under the command line to device code and command code to run this procedure as a parameter to control the effect of observation.

Has been eliminated because the ISA slot, but in some areas of industrial control more applications, together with the customer card at the time of the secondary development of programming is more difficult to read the current code used in the use of an external serial-type devices, in addition to a functional reading, there are 8-channel infrared control output interface, the direct programming of serial port because it is convenient to operate.

The following code to read and the main part of the controller 8 from the perspective of the use of introductory.

Reading code and 8-channel controller ordinary shell infrared receiver, infrared receiver looks like a serial-type adapter, 1.5 m long lead wire to connect through the PC-Plug DB9 serial, infrared receiver and an ordinary string I-type adapter is different infrared receiver window of Office installed on DB15 socket, which blocks the function of investigation include the following aspects:

1, +5 V power supply: the occupier 2PIN, leads to about 0.6 meters cord 4PIN through a plug to connect ATX Power PC machine, so do not need to purchase a DC power adapter;

2, infrared receiver: occupied 3PIN, leads to about 1.2 meters then the integration of soft-line infrared receiver head, when reading at the remote control button to receive the first;

3,8-channel infrared control output: occupied 9PIN, which 1PIN public side for +5 V, and then fired eight infra-red cathode tube, and fired infrared tube 8, respectively, then the negative output terminal of each path can be infrared, the red outside the general management and the installation of infrared remote control launching tube is exactly the same;

4, serial device programming process: the occupier 4PIN, that is, +5 V, GND, Data DTA and clock CLK, the main type and code used in programming the remote control, it can be changed through this interface directly on the remote control code type string line process control code of the 24C02 device.

Because the power supply terminals can be shared, so the above four functions can be used in all 15PIN the DB15.

And card-style reader is similar to an external serial-style reading and 8-way controller reading program for getc.exe, code procedures made putc.exe, are the procedures under pure DOS. Because it is oriented, serial programming, so the secondary development need to know to send data to serial format can be, which is designated as the head terminal 0x5a, four-byte code of the equipment DeviceCode, 2-byte command code CommandCode channel No. CheckCode Check Channel and can be, so the operating system and development tools from the restrictions, customers have written to the serial data, whether it is VC, VB, DEPHI a provision or any other process can be very convenient tools to carry out the second development.

All I need to know and apply the UIR technology company, integration of reading and coding Control 8 appliances must be entry-level products.
Product ordering information is as follows
Name: home appliance controller
Model: UIR48
Parts: the controller provides a set of home appliances, one DB9 serial port from the computer to receive control commands, a DB15 socket 2PIN access through +5 V power supply, 9PIN can access through the eight fired infrared tube, the sea can provide the necessary +5 V ( 500ma) one of the DC power supply.

At present, USB interface can also provide the products, in addition to USB interface is COM rather than outside, USB can be customized without the need for external power supply, the appearance made little difference. But one thing to note: the current USB interface products, so the controller can only be made use of code, but not reading, that is not used when reading. See right, USB line length 1.5 meters, the other side for the Block DB15, 8 leads to the need for infra-red tubes occupied 9PIN, standard products factory installed only two infrared launch tube and a red LED, red LED can be seen whether or not to issue a light, because the issue of a red LED light also contains a lot of infra-red components, but also to a certain extent, control of home appliances.

For some professional engineering applications, can be considered the product rack, 1U up to provide 24-channel infra-red output, and is an independent control.

The main application areas:
Centralized control of multimedia systems (in the control system), home appliance control automation, and the Court House at the scene to check the video control, to display multimedia presentation systems, home appliances manufacturers remote control function automatically detects the product and so on. In short, those who need to use a computer or network infra-red remote control of the traditional home appliances (TV, video recorder, embedded hard disk video recorders, VCD / DVD, lights, curtains, automatic doors) device where the product can be used.
