About the ControlNet Ex Fiber Repeater Hub
Use the repeater adapter (1797-RPA) and the fiber module (1797-RPFM)
together to form a repeater hub within the hazardous area to extend the
length of the ControlNet Ex segments to interlink systems all operating
within the area.
The 1797-RPA repeater adapter, configured with at least one repeater adapter,
functions as the intelligent starter block for a multiport repeater. The
1797-RPFM is a nonintelligent fiber-to-backplane conversion device,
converting glass-fiber infrared LED media signals to backplane signals for use
by the 1797-RPA.
A maximum of two 1797-RPFM modules may be used with one 1797-RPA
adapter.
