BRIDGE or REMOTE I/O functioning
The Z-LINK1 modules represent a communication systems for data acquisition and
transmission in the process control and industrial / civil automation. Based on an UHF
modem radio, Z-LINK1 is able to comunicate with Z-PC line modules through ModBUS
protocol. Z-LINK1 represents a new platform communication in radio frequency.
