2. PCI Asynchronous Multiport Controllers
2.1. 8-Port Async Controller EIA-232 (DCCG087)
The 8-port Async Controller provides support for attaching a maximum of eight EIA-232
asynchronous serial devices (such as modems, terminals, and printers) to an Escala system unit.
Hardware
•
Eight asynchronous ports
•
PCI bus
•
Compatibility with EIA-232D requirements
•
20 MHz IDT3041 RISC processor
•
128K memory
•
2 16C554 quad UARTs
•
Each port can be configured for the following baud rates: 50, 75, 110, 134.5, 150, 200, 300, 600,
1200, 1800, 2400, 4800, 9600, 19200, 38400, 57600, 76800 and 115200 bps
•
Form factor : short length card
•

Cables
The base board provides a 78-pin female D-shell connector. An 8-port DB25 DTE Connector Box
comes standard with the controller and provides the eight connectors for device attachment.
Attachment
The controller fits into a single PCI slot.
