Grass Valley K2 System Guide v.9.0 - Manual (Page 213)

Using BVW protocol to control K2 systems
BVW commands are available via RS-422 serial ports.
A subset of BVW commands is supported through AppCenter in protocol mode.
Insert/Edit is not supported.
In AppCenter, you must set a channel’s options to enable protocol control of the channel.
Subsequently, when the K2 Summit/Solo system starts up, the channel is immediately available for
protocol control. Manual log on is not required.
For channels in gang mode, the protocol must connect to the lowest numbered channel in the gang.
This is required to support jog/shuttle of ganged channels.
To set in and out points with BVW protocol, load clips only from the working bin.
Special considerations for automation vendors
The following information is provided for your convenience as you set up your chosen automation
product to control K2 systems. Consult your automation vendor for complete information.
Harris settings
The Harris automation product uses VDCP protocol.
The following settings are required for the Harris automation product:
Comments Same
compression
format playout Mixed
compression
format playout Setting
— 10 frames 1 second Disk Prerolls
These two settings should be the same as
the Disk Prerolls setting. However, if
there is extra fixed latency in your
RS-422 communication path, you might
need to adjust the settings differently. 10 frames 1 second Frames to send Play
early (Preroll Play)
10 frames 1 second Frames to send Record
early (Preroll Record)
This is the minimum required by K2. Do
not use the Harris default value, which is
10. 60 frames 60 frames Disk Port Comm

RS-422 protocol control connections
You can control the K2 Summit/Solo system with remote control devices and software developed
for the K2 system that use industry-standard serial protocols: AMP, BVW, and VDCP. (AMP
