If you need to place the 2110BAC modem between two segments of MS/TP bus, wire a stub length of 6 inches or less, as shown in Figure 1, and terminate the two pairs of MS/TP bus cable at the end of the stub length.

If the fiber modem is at the end of a segment, set the EOL to In.
Important: If the fiber modem is at the end of a network segment (one wire connected) then you must use the built-in termination. Failure to use the built-in termination will affect the biasing and other electrical characteristics of the trunk.
