2.4. 64-Port Async Controller EIA-232/RS-422A (DCCG089)
Discontinued: 30/04/2003.
The 64-Port Async Controller provides support for attaching a maximum of 64 EIA-232 or RS-422A
asynchronous serial devices (such as modems, terminals, and printers) to an Escala system unit.
The Controller is delivered with a 3 meters EBI (External Bus Interface) cable and has an EBI out
connector, that allows up to four 16-port connector boxes to be daisy chained. The maximum distance
between the adapter and a connector box is 6 meters. EIA-232 and RS-422A connector boxes can be
mixed on the same daisy link. The first two connector boxes are power supplied by the 64-port
adapter; the third requires an external power supply for the two last ones.
This configuration provides support for up to 64 EIA-232 or RS-422A devices per PCI slot.
