Internal Jumper Selection
To access the
DXE-RFS-2
jumper blocks, remove the 6 screws holding the connector plate of the
DXE-RFS-2
unit to the enclosure. Pull on the plate to separate it from the enclosure. The jumper
blocks should be visible and oriented as shown in
Figure 5
.
Important Note:
You cannot use coax or any other conductor for multiple functions. If
you are going to use the coax for directional control, then you cannot use the coax for
power-a separate cable must be used. We recommend using the default configuration.
Default Jumper Configuration Settings
Figure 5
shows the default jumper settings for the
DXE-RFS-2
. For JMP1 & JMP2 the center and
top pins of both are shorted. For JMP3 & JMP4, the center and bottom pins of both are shorted.
