CAUTION! Please be certain to secure the DIM-485 module to the MS-9200 and to keep all wiring
from mechanically interfering with the DIM-485.
Note:
1) Ferrite Core P/N 29090 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 communication wires be
separate whenever possible.
