CCM Card Selling Points
The CCM (Channel Control Module) card series is designed to be robust and adaptable.
- Using the ISA slot in I/O mode (I/O defines "Input / Output" for robustly interfacing CPU's to Hardware) allows the card to operate reliably in most PC's. This interface is slower but more robust and portable than other interfaces commonly in use (such as memory or DMA porting).
- The right hand side of the card is entirely committed to cable impedance matching to ensure best image quality over long runs of coax. Tested ranges are PAL - 200m, VGA 50m (tested with negligible loss up to 100m).
- technology is simple and thus easily repaired and supported.
- Excellent MTBF (Mean Time Between Failure) statistics.
- Supported in software by a range of drivers including driver operating in DOS, Windows 311, Windows98, etc.
The CCM's I/O only interface architecture and lack of interrupts makes these cards popular where stability is critical.
