Fire-Lite DIM 485 PID

DIM-485 Installation Drawing 50380 Rev A 10/30/95 ECN 95-458 power before installing the DIM-485. Insert the plastic standoff, supplied with the DIM-485, into the hole near the J11 connector on the top right side of the MS-9200 main circuit board. Align the connector on the board with J11 on the MS-9200 main circuit board and align the hole on the DIM-485 with the standoff into the main circuit board. Carefully seat the DIM-485 connector on the main circuit board J11 connector press to seat the DIM-485 on the standoff. to Note 2) Main Circuit Board in grounded box Core P/N Required VDC TB4 3 (+) 4 (-) in grounded box in grounded box Core P/N Required EIA-485 EIA-485 (-) 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. Disconnect all power from the MS-9200 before installing and wiring the DIM-485 module. Earlier versions of the MS-9200 main circuit board do not have a hole near connector J11, preventing insertion of the standoff. Ferrite Core P/N 29090 is required to meet FCC Part 15 requirements if the EIA-485 wiring is not in conduit. Twisted, shielded is recommended for the EIA-485 communications loop. Six conductor overall shielded wire may be used for the four EIA-485 wires and the two power wires. It is, however, strongly that the power and communication wires be separate whenever possible.
