MPRTM0020 Technical Product Specification – April 2006
Operating the Unit
3.4 Digital Ground to Chassis Ground Connection
Digital ground can be tied to chassis ground through a jumper (P2) located near the bottom, right
corner of the RTM.
In the default grounding for the MPRTM0020, digital ground is isolated from chassis ground
(jumper link connecting “NC” to “GND”) as shown in Figure 2.
To connect the digital ground to the chassis ground, follow this procedure:
1. Remove the jumper link from the default location on P2 (connecting “NC” & “GND”).
2. Place the jumper link over pins 2 & 3 to connect “GND” to “EGND” as shown in Figure 3.
