3 VFC-3000 Controller Connections
Power Connection (J13)
The power cord should plug into J13 on the VFC-3000 controller. A fuse holder is located
in the socket connector on the VFC-3000 controller. If this fuse fails, the Power LED does
not light. Replace it with a fuse of the same voltage and current ratings.
Plug the 120/240 VAC plug into a power strip outlet that is on a separate circuit
dedicated to control equipment. This outlet must not be a GFCI outlet.
VFC-3000-to-Display Connections (J3, J4, J11, and J12)
The VFC-3000 controller is capable of interfacing to the display via fiber-optic (J3, J4) or
Cat-5 cables (J11, J12).
Fiber-optic Cables (J3, J4)
The fiber-optic option is the preferred interface due to its electrical isolation and immunity
to electromagnetic interference. It enables the VFC-3000 controller to be located up to
2,500' (762 m) from the display. The fiber-optic option requires a pair of 62.5/125 µm fibers
with ST connectors.
• Connect the transmit (TX) cable (J3) from the VFC-3000 controller to the receive (RX)
connector (J6) of the CAN distribution board located inside the display.
• Connect the VFC-3000 controller’s receive cable (J4) to the transmit connector (J5)
of the CAN distribution board.
If the VFC-3000 controller is located in a traffic cabinet, run these cables in conduit. Make
sure the bend radius of the fiber-optic cable is not less than the cable manufacturer’s
recommendation.
Cat-5 Cable (J11, J12)
The copper Cat-5 cable display interface option uses standard Cat-5 cable with RJ45
connectors. It enables the VFC-3000 controller to be located up to 1,500’ (457 m) from
the display. The Cat-5 cable terminates in the RJ45 plugs as shown in
Figure 4:
