Making detailed settings for a P-Bus
device
1
In the Engineering Setup >Panel >Device Interface
>Serial Port Assign menu (7325.5), select the serial
port connected to the P-Bus device for which you want
to make the settings.
2
Press [Port Setting].
The P-Bus Setting menu (7325.6) appears. At the top
of the status area, the relevant serial port, slot number,
protocol, serial port name, and SCU number appear. In
the lower part of the status area, the device name and
response speed settings appear.
3
Select the ID for which you want to make a device
name setting.
4
In the <Name> group, press [Set].
5
Input the desired name, and press [Enter].
To return the device name for the selected ID to the
default name
Press [Clear] in the <Name> group.
6
Specify the command to which the response speed
setting applies.
7
Set the disk recorder response speed.
8
Press [Delay Set].

as required to make the settings for
other commands.
Making detailed settings for a VTR
1
In the Engineering Setup >Panel >Device Interface
>Serial Port Assign menu (7325.8), select the serial
port connected to the VTR for which you want to make
the settings.
2
Press [Port Setting].
The VTR Setting menu (7325.7) appears.
At the top of the status area, the relevant serial port,
slot number, protocol, serial port name, SCU number,
and timecode source appear. In the lower part of the
status area, the VTR constants appear.
3
In the <TC Source> group, select the timecode source
(reference signal for determining the tape position)
from the following.
LTC (Longitudinal Time Code):
Uses LTC. When
interpolation data is returned from a VTR, use that
interpolation data.
LTC:VITC (Vertical Interval Time Code):
Normally uses LTC, but when the tape is moving
at speeds at which LTC cannot be read, use VITC.
When interpolation data is returned from a VTR,
use that interpolation data.
VITC:
Uses VITC.
CTL (Control):
Uses CTL pulses or timer counter
pulses. Use this only for a tape on which no
timecode is recorded.
The displayed tape position is based on the reference
signal specified here.
4
Specify the VTR constants to set.
5
Press [Set].
A numeric keypad window for hexadecimal input
appears.
6
Set the VTR constants using values in the range 00 to
FF.
7
Press [Enter].
8
Repeat steps
4
to
7
as required to set the constants for
other VTRs.
