GUIDE TO INSTALLATION AND OPERATION The Mode LEDs are bicolor and indicate the status of the input signals, as follows: Green: the mode is operating correctly; Red: indicates an invalid or absent input signal. Check that the mode selected conforms to the equipment connected or verify that there is an input signal pre- sent and that cables are properly connected. - Page 13 GUIDE TO INSTALLATION AND OPERATION Figure 3.2 Underside of the DV-Bridge+ The TIME CODE INSERTION LINE SELECTION switches allow you to turn DVITC time code insertion on or off, and when on, to choose the lines where you want to insert the time code. The DEFAULT switch lets you choose the default video standard (525 or 625 lines).
- Page 14 GUIDE TO INSTALLATION AND OPERATION • If you set this switch to TRIBUTARY, you can control the DV- Bridge+ and a DV VTR by its iLink port through the RS-422 link as if it were a 4:2:2 VTR. Be careful to plug only one IEEE-1394 device into the DV-Bridge+ in this mode.
