Communications Submenu
The Communications submenu lets you set up the serial
communications ports. These ports, are labeled Serial 1, Serial 2, and
Serial 3 (LINC) on the back of the Signal Chassis. Each port is
independent, and all can communicate simultaneously. See Section 3 –
Installation for more details on these ports.
Use the Protocol pushknob to select a communication protocol. See the
manuals that came with your editor to determine the correct protocol.
GVG – The 8150 communicates with edit controllers using Grass
Valley Group RS-422 protocol by emulating a GVG Model 200 video
switcher. This setting also works with the Accom A82/A83 and GVG
Model 1000 protocols.
SPARE – Reserved for future use.
Sony – The 8150 communicates with edit controllers using Sony
RS-422 protocol to run timeline commands by emulating a Sony VTR.
SMPTE
– The 8150 communicates with edit controllers using SMPTE
RS-422 protocol to run switcher and timeline commands.
LINC – The 8150 controls external devices that support LINC ( L ocally
I ntegrated N ode C ontrol). LINC lets you frame-accurately run DVEs,
DDRs, etc. as part of an 8150 Timeline effect. This setting is valid only
for Serial Port 3.
Use the Baud pushknob to set the baud rate for the serial remote port:
1200, 2400, 9600, 38400, or 76800. See your editor’s technical manual for
the correct baud rate setting.
The
Parity
pushknob toggles
Odd
,
Even
, and
Off
. See your editor’s
technical manual for the correct parity setting.
Most edit controllers can send edit preview switch commands to the
switcher, which then performs the preview switch on an Aux bus output.
Since the 8150 uses the preview output as the edit preview switcher, it
must re-route these preview switch commands to the preview output.
In the Engineering Comms submenu, the
Preview cmds routed from:
pushknob toggles
None
,
Aux 1
,
Aux 2
,
Aux 3
,
Aux 4
, and
Aux 5
. This
selects which Aux bus command is processed as a preview output
command. For example, if you select
None , it switches all Aux outputs
normally and does not switch the preview output at all. If you select Aux
4
, the 8150 routes any crosspoint switch commands intended for Aux 4
to the preview output, while continuing to switch other Aux buses
normally. If you select
Aux 5 , you can set the edit controller to execute
preview switching on Aux 5. Since the 8150 has no Aux 5, you can use
this setting to let the editor control all four Aux outputs, plus the preview
output for preview switching.
