3.4Digital 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.

Figure 2. Default Grounding on MPRTM0020

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.
