All “-R3” models receive power from the back plane of the R3 rack. Insert the “-R3” unit into any
available R3 rack slot such that the female 3-pin connector on the back of the module engages the companion
male connector of the back plane. The red power LED will glow when voltage is applied to the unit.
CAMERA / RECEIVER-DRIVER CONNECTION
Attach a 75 ohm coaxial cable (terminated with BNC connectors) from the camera/receiver-driver’s BNC
connector to the "VIDEO IN" BNC connector on the VT1505 series module.
CONTROLLER CONNECTION
Attach a 75 ohm coaxial cable (terminated with BNC connectors) from the controller’s “Video In” BNC
connector to the "VIDEO OUT" BNC connector on the VR1505 series module.
FIBER OPTIC CONNECTION
Select a quality fiber optic cable containing either 50/125 or 62.5/125 fiber and attach a ST style fiber
optic connector using the connector manufacturer's recommended procedures. Connect the fiber optic cable to
the ST connector marked "OPTICAL OUT" on the VT1505 series module to the ST connector marked
“OPTICAL IN” on the VR1505 series module. In a similar fashion, connect the fiber optic cable to the ST
connector marked and "OPTICAL IN" on the VT1505 series module to the ST connector marked “OPTICAL
OUT” on the VR1505 series module.
NOTE
: When using a “WDM” fiber optic module (single fiber unit), connect the fiber optic
cable to the ST connectors marked “OPTICAL CABLE.” on the VT and VR modules
