The service port for NRM models LP-NRM5xx-000C and 
LP-NRM6xx-000C is a 6-pin Modular Jack connector and is used for the 
connection of the Medium User Interface (Figure 15) to provide advanced 
monitoring and adjustment access to the connected FX field controller 
over the local link bus. The connector provides access to the local link bus 
and a power supply of 15 VDC for the MUI.
