Hitachi HV-D25 operation manual 12OUTPUT/SYNC, GL Mode

139 INITIALIZE: Mask settings are initialized to factory values for each application file. Simultaneously press the L and R buttons for about 2 seconds to return the selected files to the factory settings. See Page 25 for the factory settings of each application file.

12￿OUTPUT/SYNC

On this menu screen, you can make signal changeover for output to the D-SUB connector and phase adjustment for external synchronization.

1) OUTPUT:Output mode changeover

L R

R,G,B Y,R-Y,B-Y Y/C

∙R, G, B:The R, G and B video signals are output to the D-SUB connector.

∙Y, R-Y, B-Y:The Y, R-Y and B-Y signals are output to the D-SUB connector.

∙Y/C:The Y/C signal is output to the D-SUB connector. It can be delivered simultaneously with the Y/C signal output from the Y/C connector (S terminal).

2)MONO: Monochrome (black and white) ON/OFF for the video output signal from the VIDEO connector

Set to ON for monochrome. Setting ineffective during color bar.

3)SYNC ON G: G video signal synchronization ON/OFF (In the R/G/B mode only) When output is RGB with Sync on and G on, Sync is added to the G video signal.

4)GL IN: Impedance changeover of input to the GL IN connector.

HIGH:The high impedance level is provided.

75Ω:An impedance of 75 ohms is provided.

(Note) When power to the camera is turned off, the high impedance level is provided. So, do not use this function in a system where power is turned off for the camera unit only.

5)GL MODE:

∙VBS:The VBS signal or BBS (black burst) signal is input as an external synchronizing signal.

∙HD/VD:The HD/VD signal is input as an external synchronizing signal.

(Note) During external sync with HD and VD signals, be sure to use either RGB or Y, B-Y, R-Y output signals. Although VBS and Y/C output signals are also produced, these cannot be used as normal output signals.
