3. Configure the IED port in RS 485 mode. The IED port is shown in Figure 1 or 1a depending upon the
unit, illustrations 3 and 3a. Some rack mount units and all Table Top ORION units have a DB 9 port
for RS 485 device connection whereas some Rack Mount ORION units may have three screw
terminals for an IED port physical connection. FOR AN ORION RACK MOUNT UNIT: Remove the
two screws from the rear of the unit as shown in Figure 1, illustration 4. Slide the metal cover away
from the unit to expose the electronic boards contained within the enclosure. As shown in Figure 3,
five jumpers , JP 11, JP 12, JP 13, JP 14, and JP15 shall be placed in the appropriate positions for
RS 485 communication as indicated in Figure 3 (JP 11 through 14 in the closed position and JP 15
closed to insert resistor termination). Breakouts of each of the jumper locations are shown in
Illustration 1 and Illustration 2. The position of the jumpers in the “open” or “closed” positions are
highlighted. FOR AN ORION TABLE TOP UNIT: For the Table Top Unit the instructions for dis-
assembly are much more involved . Follow the dis-assembly instructions as presented in Figure 3A.
Install the jumpers JP 11, JP 12, JP 13, JP 14, and JP15 as defined in the Table presented in Figure
3A.
4. Reassemble the unit following the reverse order of the tasks as presented in step three of this Quick
Start Guide.
