FIGURE E-1. NL100 to MD485 Conversion
Where an NL100 to MD485 network is desired, the following configurations
will provide communications in transparent mode, with MD9 emulation or
with PakBus Networking. The NL100 does not perform MD9 emulation. So
at least two MD485s are always required for MD9 emulation with an NL100.

a. MD485(s)
b. NL100
c. NL100 Transformer (CSI Item #13947) or other source of power for
