The Intel MPRTM4808 board front panel provides the following connectors and controls:
Caution: The Intel MPRTM4808 board provides several RJ-45 connectors that commonly serve as different
interfaces (RS-485, twisted pair Ethernet and telephone). Connecting different interfaces (e.g.
Ethernet and RS-485) may damage the board. Therefore, make sure that you only connect
matching interfaces. Furthermore, take note of the following:
• Clearly mark TPE connectors near your working area as network connectors.
• Connect TPE bushing of the system to safety extra low voltages (SELV) circuits only.
• Ensure that the length of electric cable connected to TPE bushing does not exceed 100 meters.
