Operation and handling of the 

LWL-RS422

Set up the devices at the dedicated places.

Take care of the pinning of the RS422 links (see Fig. b.1 or housing) 

while connecting the cables and be aware the system to be 
unpowered during connecting the cables.

Connect the optical fiber (Out => In; In => Out). Only use 
62,5/125µm multimode fibers.

Turn on all devices (power push button, see Fig. a.1); the order does
not matter

The transmission starts automatically after a short initialisation.
