Chapter 13 Interfacing With External Devices
Overview
In a DVS-7250 I/O expansion system, you can carry out the following
control on a maximum of two VTRs connected to the control panel.
• Controlling the VTR tape transport from the DME control panel
• Saving VTR control data (start point, stop point, and start offset point) in a
register
• Recalling VTR control data from a register, and using the same operation as
for a key frame, controlling the VTR tape transport
The interface with a VTR requires an optional BKDS-7001 Control Port
Extension Board to be installed in the control panel.
Tape Transport Control
To select a VTR
Using the sub-register selection buttons in the numeric keypad section, select
the VTR to be controlled.
To select VTR 1, press the V1 button, and to select VTR 2, press the V2
button. If both buttons are lit, you can control the two VTRs simultaneously.
To control the tape transport
Use the buttons in the DME control panel to control the VTR tape transport.
ORTHG (VTR): Press this button, turning it on, to control the VTR from the
DME control section. When this button is lit, the other buttons have the
following functions.
To use the ORTHG button for VTR tape transport control, in the setup
menus a setting is necessary for using this button as a VTR button. For
more details, see the section “Changing switcher functions (OPERATION
MODE menu)” (page 14-59).
X (REW): Rewinds the tape.
Y (PLAY): Plays back the tape.
Z (FF): Fast forwards the tape.
CLR WORK BUFF (STB OFF): Switches to “standby off” mode.
CTR (STOP): Stops the tape.
VELO HOLD (JOG): Moves the tape at a speed dependent on the rate of
rotation of the search dial (jog mode).
