GICAM sells various types of signal converter. We have signal converters that transmit serial protocols by radio frequencies, very simple to program and control. Our converters are suitable for use in industry. We offer signal converters that transform analog input signals into standardized analog signals, and signal converters that can be connected to devices that have RS-485 or RS-422 protocols.
