Note:
The DE100 Ultra 160 may be shipped with an isolator/repeater
board factory-installed. If this is the case, your DE100 Ultra 160 will
look slightly different from figure above. Please refer to figure below

The DE100 Ultra 160 Isolator/Repeater Board is an upgrade attach-
ment for the DE100 Ultra 160 receiving frame. This attachment pro-
vides both an enhanced, bus-isolating hot swap and repeater function.
