Notes:
1) Ferrite Core P/N FBD-1 is required to meet
FCC Part 15 requirements if the EIA-485
wiring is not in conduit. Twisted, shielded
wire is recommended for the EIA-485
communications loop.
2) Six conductor overall shielded wire may be
used for the four EIA-485 wires and the two
power wires. It is, however, strongly
recommended that the power and communi-
cation wires be separate whenever possible.
