Dim-485 Installation.
CAUTION! Connect all wiring to the DIM-485 terminals before
plugging it into connector J11 on the MS-9200 main circuit board.
1. Carefully align the DIM-485 connector with the four pins on
connector J11 of the MS-9200
2. Press firmly on the DIM-485 connector to seat properly on con-
nector J11 being careful not to bend any pins
3. Be certain to secure the DIM-485 module to the MS-9200 and to
keep all wiring from mechanically interfering with the module.

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.
