4 3. INSTALLATION Connect one end of a DB15 cable to the TBC 2. Connect the other end of the cable to the DB 15 on the VTR to be controlled. Identified as TBC Remote or External Control. Because the TBC Remote connector has power on its pins, cabling should be done only with the VTR power switch turned off. Once the TBC 2 panel is securely connected to the VTR, power may be safely turned on. Installation is complete. CONNECTION DIAGRAM 4 TBC-2
