This product is used for all RS-232 asynchronous serial communication control system and a variety of industrial CNC machine tools (CNC lathe, milling machine, machining centers, EDM wire EDM, etc.), the main function is to program optical computer numerical control isolation and then transferred to multiple different numerical control devices to address the RS-232 communication interface in the transmission process of interference often wrong, easy to damage the computer and the machine console, telematics procedures can not be problems, so that the device poor working environment can be safe and accurate completion of communication, can help achieve a computer programming and numerical control equipment to control more than one communication, is the optimal arrangement of NC workshop. 

 Features: 

 1, serial remote communication device by the host server and the machine servers, new design concepts; 
 2, with independent power supply, electronic switching converters, optical isolation, safe, durable, accurate and reliable long-distance communications; 
 3, the communication device can communicate on the status indicator at a glance; 
 4, renounce the use of the traditional theory of shielded cable to avoid the bad or the equipment ground insulation of the potential safety equipment caused by ground loops; 
 5, stable and accurate long-distance transfer program (a few hundred meters), so the computer can be placed on the use of a suitable working environment (for example, in the office, to facilitate the management of production); communication line length limit no longer be free to beautiful aspects of installation, the production site clean and bright; 
 6, different manufacturers and models of machines can be online at the same time; 
 7, easy to use, without changes to any line of machine tools. 

 Performance: 

 1, for all to use RS-232 asynchronous serial communication in a variety of CNC machine tools and industrial measurement and control systems; 
 2, dual-channel, full duplex mode, which also can send and receive; 
 3, perform RS-232 asynchronous serial communication handshake protocol (no protocol, XON / XOFF, RTS / CTS, DSR / DTR). 

 Model and specification: 

 1, A-type - 5 port (for connecting devices 5) 
 2, B-type - 9 ports (devices can be connected to 9)
