Ethernet to Serial Port Converter

I-7188EN converter is a bridge between the Ethernet and RS-232/422/485. After installing VxComm driver on the PC, users can create Virtual COM ports

mapped to the COM ports of the 7188EN. The original software (based on COM port) can connect with remote RS-232/422/485 devices via the Ethernet without any modification. I-7188EN is the most cost effective method to combine your original serial device with Ethernet communication ability.

Note: Both I-7188E3 and I-7188E3-232 have 4x DI and 4x DO

Bộ chuyển đổi Sharer cổng RS-232/485

The tSH-700 module is a serial port sharer that provides a number of functions, including "Baud Rate Conversion", "Modbus RTU/ASCII Conversion" and "Two Masters Share One Slave". The built-in web server provides easy configuration interface, and no console commands are required.

This function allows a single master device to communicate with slave devices using different baud rates and data formats. Most query-response protocols (half-duplex), e.g. DCON, are supported in the raw data mode. Full-duplex communication should also work when the data size is smaller than the built-in 512 bytes buffer on each serial port.

This function allows a single Modbus RTU/ASCII master device to communicate with Modbus RTU/ASCII slave devices using different protocols, baud rates and data formats.

This function allows two master devices connected to different serial ports to share slave devices. Modbus mode can be used to convert the Modbus RTU/ASCII protocols, while raw data mode can be used for DCON or other query-response protocols. Different baud rates and data formats can also be used on the different serial ports. The built-in cache function reduces the loading of serial communication on the slave port by removing duplicated queries when the two master devices are requesting the same information.

Note: It's recommended to have large timeout value and scan interval settings on the two masters, since the slave port is now having double loadings

The built-in read-cache function is used to store previous requests and responses of the Modbus messages in the memory buffer of the tSH-700 module. When other HMI/SCADA master controllers requiring the ame information from the same salve RTU device, the cached response is returned immediately. This feature dramatically reduces the loading on the slave serial port communication, ensures faster responses to the master, and improves the stability of the entire system.

Bộ chuyển đổi Addressable RS-485 sang RS-232

There are many RS-232 devices in industry applications. Nowadays it becomes important to link all those RS-232 devices together for automation & information collection. Usually those RS-232 devices are far away from the host-PC & widely distributed in the factory. I-752N has one RS-485 port and several RS-232/422 ports. It can assign a RS-485 address number to each RS-232/422 port. By the functionality, the host PC can send data to specific RS-232/422 device link to the I-752N via the RS-485. And the data won't case network conflict.
