The RS232 is a asynchronous serial communication system that is used to connect and control various device devices, such as computers and industrial equipment. The RS232 hardware can communicate up to 15 m (50 ft) and only use point to point between the PC serial port and the device, or 1:1 connection.
However, this product is designed to be able to be connected to multiple equipment, away from the 1:1 communication connection.
However, this product (MSD-1400) is limited to two-way communication for one channel of the 1:4 connection method, which is identical to the existing RS232C communication connection protocol, and for the other three channels, only receives data output from the other equipment.

In addition, this system supports 100% of the communication speeds supported by RS232 without a separate set, and also serves as an RS232C repeater, which allows the RS232 communication connection to be extended.

This product has an AC/DC power adapter attached.
A cable for the output connection of the three channels, which is a one-way data output port, is attached together. However, an extension cable for RS232 ports with bi-directional communication is not attached.
Please review the specifications of your equipment's communication port and prepare the appropriate cable for use.

Application: Distribution of bar code signals by RS232 communication method, distribution of GPS data, distribution of electronic low signal, distribution of various measuring equipment signals
