Wireless Data Acquisition & Control
Our DATA LINK and SWITCH LINK systems use DSSS (direct sequence spread spectrum) 2.4GHz radios and embedded microprocessors for data transmission between our sensors and touch screen panels. The DL-TXH-422 remote data acquisition module collects up to six analog sensor inputs and transmits the data to the DL-RXH-422. The DL-RXH-422 has an RS422 (optional RS232) interface for input to our touch screen systems or two analog output.
