2.  WIRING

A conventional remote display and/or FCR-2107 series radar can be connected to 
J617 and J 618 in processor unit as sub-display. However, the GAIN and STC controls 
function differently depending on J617 and J618. Refer to the tablet to connect sub-
displays.

Use screws (M3x6, supplied) to attach the wiring plate 1 and wiring plate 2 assy to the 
processor unit. Connect the cables shown below to the connectors at the front of the 
processor unit. After the connection, bind cables to the appropriate fixing metal with 
the cable ties (supplied).

For the cables from the monitor unit (type: DVI-D/D SLINK5M/10M (MU-190 only), 
DSUB9P-X2-L5/10M) and ground wire, connect them to the processor unit directly 
(without fixing to a wiring plate). Tighten the fixing screws on these connectors to pre-
vent disconnection from the processor unit.

Note: Connect the cables so that they do not interfere with the opening or closing of 
the DVD tray.

Overall gain

Even if input video level is ad-
justed to 4 Vp-p, the gain is 8 dB 
lower than that on the master ra-
dar.

The gain is 8 dB lower than that on 
the master radar.

J618
(SEMI-LOG)

Overall gain

When input video level is adjust-
ed to 4 Vp-p, the gain becomes 
the same as that on the master 
radar.

The gain is almost same as that on 
the master radar.

ton.

STC control

The STC control functions, how-
ever this control is added on the 
signal adjusted by the master ra-
dar. So this port is not recom-
mended to use.

The STC control does not function.
