Troubleshooting
To start watching the changes in the status it is necessary to send the ZW999 <CR> command.
The status report has the form of ZSOOOIIILLLLLLLL <CR> where OOO specifies the destination,
III specifies source and L specifies level. For example, destination 7 set to source 21 on levels 1
and 5 will produce status report
ZS007002115 <CR>.
Digipath
The Digipath router is equipped both with RS-232 and RS-422 ports. In order to connect to the
RS-232 port you will need a straight cable. When using the RS-422 port, you may use the
Addenda Electronics Rosetta Stone converter (
http://www.addenda-elect.com/) or
similar to connect the router to the PC. The default settings for the ports are :
• 19200 baud
• 8 data bits
• No parity
• 1 stop bit
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
192.0.2.2 and for the app server it is 192.0.2.1. GVG recommends that
you add the following two lines to your hosts file:
192.0.2.1 pc
192.0.2.2 sms7000
