The Initial RSN system will use two types of junction boxes (J-Box). The first type is a Medium Power J-Box (MP J-Box) that receives input voltage at 375 Volts DC and an input data link at 1 GigE. The MP J-Box will have one expansion port that passes on the 375 Vdc and 1 GigE data link. This port can be connected to another Medium Power J-Box, or to other specialized equipment that requires higher power or bandwidth, e.g., inductive power coupler systems in docking stations for charging batteries in mobile platforms, or high-definition cameras. In addition, the MP J-Box has eight instrument ports that provide 12 to 48 V and has 10/100BASE-T, RS232 or RS485 data links. There will be 13 Low Power and Medium Power Junction boxes on the system.
