　　・This is a transmission multiplexer with a 1:N buffer, which can communicate with multiple
　　 RS-232C terminals from the host computer's RS-232C or GP-IB interface.
　　・Four RS-232C terminals can be connected to one multiplexer, and multiplexers can be
　　　added using GP-IB or optical cables.
　　・As the terminal's RS-232C port is isolated, it has high anti-noise properties.
　　・It is easily controlled using flexible commands for operation and functions.
　　・Transmission speeds of 300〜 19200bps can be set for each channel.
　　・Transmission buffer: 16Kbyte trans., 16Kbyte rec. (for each channel)
