Wire-cut computer online optical isolation transmitter (will never burn the print port and motherboard)

It solves the problems that the traditional online is susceptible to interference errors, frequent damage to the computer and the machine tool console, and the ability to send numbers over long distances.

The drawbacks of the response transmission method:

When the wire cutting controller and the wire cutting software are transmitted online by a computer, they are divided into synchronous transmission and response transmission, that is, synchronous reception and response reception for the single board machine.

Opto-isolators are primarily intended for acknowledgment transmission and reception, as only responsive single-board machines have this problem (because optocoupler and current limiting are not implemented in responsive single-board machines). At present, most domestic manufacturers of response-type single-board machines are in Shanghai, Ningbo, Jiangsu (because they are relatively early wire-cutting production bases, although they are production bases, the responsive technology is derived from the telegraph head input principle. It is very backward, outdated technology, with the continuous upgrade of electronic and computer hardware, but the line cutting controller system single board machine has not been updated, maybe they can not solve this problem, so it appears during the transfer process. : burning computer print port, online problems, etc.)

When answering transmission and reception, the single board machine needs a certain value of current output to the computer print port to indicate the communication handshake signal, so that there is a possibility that the computer print port will be burned out (after burning, the 3B program cannot be transmitted. ), some users often carry out hot plugging of the board and the computer's online transmission line, and when thundering, these all lead to the burning of the print port.

Photoelectric isolators:

In order to solve the problem of response transmission: "burning the print port or the motherboard, the unstable transmission is completed" problem, we designed the wire-cut computer online photoelectric isolation transmitter for photoelectric coupling and current limiting, so that the security and stability are directly connected with the computer print port. 3B program (now we have added the serial port transfer function: directly use the serial port instead of the computer print port, so as to increase the stability of the transmission, the stability is guaranteed 100%). The principle of the photoelectric isolator: the same as the "only in and out" valve (one-way check valve), the computer outputs the 3B program to the single board machine, and when the single board machine outputs current to the computer, the optocoupler Isolation, use resistors to limit current, so as to completely protect the computer print port, if you use the serial port to transmit to the single board through the optical isolator, you can always burn the computer motherboard and 100% stable transmission, single board machine 100% reception: This is our permanent guarantee to each customer.

Print port, serial port + photoelectric isolator à single board machine communication port:

1. Increased stability to 100%, efficient and intelligent, to ensure that your code transmission path is unimpeded.

2. The communication line is no longer limited by the length, and can be installed to the aesthetics at will, so that the production site is simple and bright, and the length of the transmission cable can be increased to 20 meters to 50 meters. The long-distance transfer program is stable and accurate, so the computer can be used in a suitable working environment (for example, in the office for easy management of production);

3. Significantly reduce the interference in the transmission process, almost zero, to ensure 100% transmission.

4. It is divided into low level, high level effective voltage transmission, compatible with synchronous and response type communication port, suitable for a variety of controllers that are not available. Machines of different manufacturers and models can be connected at the same time without changing any lines of the machine tool.

5. Abandon the use of traditional shielded wire theory to avoid equipment safety caused by poor grounding or equipment insulation problems;

6. Safe, durable and stable. Eliminate the risk factors of burning computer parallel port and console interface circuit due to electromagnetic interference, machine tool failure, power supply instability, etc.

Model and specifications:

1, type A - direct transmitter - 2 ports (directly connect 2 machine controllers, plus converter can be increased to 2 * 4 = 8 machines)

2, B type - direct transmitter - 4 ports (can be connected to 5 machines at the same time, plus converter can be increased to 4 * 4 = 16 machines)
