ADC-SDI

5.3 Interface with GYDA or other controllers

ADC-SDI follows the Flashlink-protocol, see the definition of the protocol available from our
web site: http://www.network-electronics.com/. ADC-SDI can also be used with any controller
or controller system that adheres to the Flashlink-protocol, using the RS422 bus. For more
information on the electrical interconnect, see the documentation of RS-2RU-10-2. The
available commands are shown in Table 6.

5.3.1 The '?' command
According to the Flashlink-protocol, no card can use the RS422-bus before the '?' (hello)
command is sent the card at least once. The response from ADC-SDI will be:
xxxxADC-SDI\
PIC sw rev X.X.X\
FPGA sw rev X\
Protocol ver X.X
Here xxxx denotes the source and destination rack and slot coordinates, while X represents
a version number. As of primo February 2002, these revisions would be:
xxxxADC-SDI\
PIC sw rev 1.1.0\
FPGA sw rev 7\
Protocol ver 1.0
5.3.2 The "info" command
This command reports the entire state of the card. An example:
xxxxChannel Select: automatic\
Locked PAL CVBS Ch. 1
Response
Yes The "Hello" command.
Yes Gives back the card state.
"OK" Set Cannel Search mode to automatic.
"OK" Set Cannel Search mode to CVBS Ch. 1.
"OK" Set Cannel Search mode to CVBS Ch. 2.
"OK" Set Cannel Search mode to S-Video; Luma Ch1,
Chroma Ch2.
"OK" Turn on EDH in output SDI.
"OK" Turn off EDH in output SDI.
"OK" Turn on the Mark Field 1-feature.
"OK" Turn off the Mark Field 1-feature.
Yes Get a value from a numbered register.
No Set a value to a numbered register.
"OK" Select luma/ chroma separation filter, see Table 4.
"OK" Select luma/ chroma separation filter, see Table 4.
"OK" Select luma/ chroma separation filter, see Table 4.
"OK" Select luma/ chroma separation filter, see Table 4.
