The following lists examples of different configurations using machine control card sets:
Limitations on Combining Classic SWB and Machine Control Card Sets
There are limitations if both the Classic SWB card set and the machine control card set are installed
in a single frame. It is not possible to install two machine control card sets in a 64-port configura-
tion while a classic SWB card set is installed because both use the same slots.
The following lists possible combinations of classic SWB card sets and machine control card sets:
Configuration Tasks to Perform Before Installing Cards
Before installing active cards, make sure all jumpers and switches are set to meet your configura-
tion needs. For configuration instructions, see
Setting Jumpers and Switches on Cards and Card
Sets on page 67.
• Control cards — configure rear connections for Ethernet or to connect to third-party router con-
trol systems and for AES reference impedance. All jumpers should be set before the card or
card set is installed.
• Analog audio cards — set gain, mute detection and operating levels.
• Sample rate converter — enables up to 16 asynchronous AES inputs with a wide range of sam-
ple rates to be supported and converts the signals to synchronous AES signals locked to a sam-
ple rate of 48
kHz.
• Classic SWB card sets — can configure the output cards for DVB/ASI operation.
• Standard SWB cards — enable automatic re-clocking of the output signal and configure re-
clockers for operation with DVB/ASI signals.
• Machine control card sets — can configure the card set to function as a 32-port standalone
Machine Control card set even if another Machine Control card set is installed, allowing for two
32 inputs x 32 outputs matrices instead of one 64 inputs x 64 outputs matrix.
• Analog video conversion module — converts incoming composite analog video (NTSC or PAL)
to SD format or converts SD formatted signals to composite analog video outputs in NTSC or
PAL formats.
