Troubleshooting

Digipath routers use binary protocol to communicate over serial port. When you're switching
crosspoints from physical control panel you will see sequences of binary data in your
HyperTerminal window

Thomson / Grass Valley GVG Series 7000 Native Protocol

For GVG Series 7000 routing switchers we're supporting Native protocol on serial and Ethernet
ports. However, our GVG 7000 Native Protocol driver only works with a serial connection. If you
want to use an Ethernet connection, please use our Sony HKSPC (GVGNP Emulator) driver,
which only works with an Ethernet connection. We will eventually merge these two drivers
together, but since we don't currently have the equipment to test our changes, we can't do it
now.
Because of performance issues, the Ethernet connections are considered more preferable. For
an RS-232 connection it is necessary to prepare a custom cable according to GVG instructions.
Recommended serial port configuration is 38400/8/N/1 without flow control. If using RS-232
to communicate to Encore, the manual wiring is wrong and it shows examples of Y cables
being used to connect parallel controllers. This method is NOT supported for RS-232 as the
terminators in the new controller frames prevent all communication.
For Ethernet, the port to connect to is 12345. It is necessary either to install an additional
network card or to configure additional IP address for existing card. The default IP address for
the GVG router is
add the following two lines to your hosts file:
192.0.2.1 pc
192.0.2.2 sms7000
Control Panel Server\RCL Server must have the IP address of Grass Valley's Application Server.
Flags and Parameters should have Protocol Type set to
Tx that can be temporarily activated to view communication between Grass Valley and
Encore.
Similar to Philips, the software assumes that there are no gaps in sources or destinations order.
The first source index should be 0, as well as first destination index.
