FOUR RS-232/RS-422 channels
8-bit TTL I/O ports
VxWorks Libraries
Available in Air-cooled and Conduction Cooled Versions
Each channel may be independently programmed for BC, RT, or RT/MT mode. This option makes use of the BU-61588/61688 device to provide full support for all modes of operation. When used with BU-61588 Mini-Ace, 4K words of memory is available for message preparation and double buffering etc.
BC mode includes advanced features such as bulk-data transfers, frame auto-repeat, automatic retries on the same channel or bus switching on alternate channel, programmable gap times etc
RT mode supports all advanced features including single buffering, double buffering, sub-address circular buffering, programmable command illegalisation and Busy etc.
MT modes allows all standard features including word monitoring, selective message monitoring etc
Simultaneous RT / monitor mode is also supported as it is required some times for backup BC terminals.
The RT address of each channel on the BISA-CCPMC-1553B may be set by Library functions. RT address is also settable through Hardware settings as per notice-2 features. In this mode the software addressing is disabled.
