Operating Safety
2.6 RJ-45 Connector
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 voltage (SELV) circuits only.
• Make sure that the electric cable connected to a TPE bushing does not exceed 100 meters.
2.7 Environment
Always dispose of used batteries and/or old boards according to your country's legislation and in an
environmentally acceptable way.
