Controlling External Devices

If you need to change the assignment of signals to cross-
point buttons, do as follows.
• In the Xpt Assign menu (see page 158), make 

assignments so that button numbers and pair numbers 
are all the same.

• In the Video/Key Pair Assign menu (see page 159), 

change the signals assigned to pair numbers.

Set the GPI signal pulse width to 1 field (frame) or more 
depending on the video format.

On the MFS-2000 system, you can control the following 
external devices from the RS-422A 9-pin serial interface 
of a Device Control Unit (DCU).
• VTRs
• Disk recorders (supporting Sony Disk 9-pin protocol)
• Disk recorders (supporting the Video Disk 

Communications Protocol)

• Extended VTRs (Abekas A53 protocol)
• Audio mixers (control from editing keyboard only)

To control external devices, one of the following DCU 
systems is required.
MKS-2700: Six RS-422A ports (standard equipment).
MKS-8700 (with optional MKS-8702 boards installed): 

Up to five boards may be installed, with each board 
providing six RS-422A ports (maximum 30 ports).

To control external devices, assign them to arbitrary RS-
422A 9-pin serial interface ports.

See page 187 for more information about how to make 
device assignments.

You can perform the following operations manually.
• Select VTRs, disk recorders, and Extended VTRs
• Play
• Stop
• Perform jog and shuttle mode search
• Set start points
• Cue up devices
• Record to VTRs and disk recorders

To perform operations manually, commands must be 
assigned to buttons in the utility control block.

See page 170 for more information about how to assign 
commands to buttons in the utility control block.

To play video from a disk recorder or Extended VTR, you 
need to read the files to play. To record to a disk recorder, 
you need to create the files to record.
