Multichannel distribution panel for RS232 data communication. Commonly used in the maritime, survey and ROV industry. Simplifies and makes a well-arranged interconnection between RS232 sensors and multiple computers. The panel allows up to eight different sensors to be interfaced up to four different computers, each. Data traffic indicators and magnetic isolation on each input channel. Solves problems with differences in ground potentials and also acts as a signal amplifier and cable extender.
