2.7. Auxiliary power supply for 16-Port connector box for 64-Port Async controller (PSSG013)
An auxiliary international power supply is required on the 3rd connector box, if more than 2 connector
boxes (EIA-232 or RS-422A) are connected to a 64-port Async controller.
The power supply is delivered with an additional plug adapter necessary for the 16-port EIA-232
concentrator. It uses a 5 pin DIN plug connector on a 6-foot cable.
2.8. 128-Port Async Controller EIA-232 (DCCG090)
Discontinued: 30/04/2003.
The 128-port Async Controller provides support for attaching a maximum of 128 EIA-232
asynchronous serial devices (such as modems, terminals, and printers) to an Escala E and T Series
system unit.
The Controller features two V11 synchronous channels that can link up to four Cluster Boxes (RANs)
each via a "daisy chain". Each of those lines must be terminated by a terminator plug (delivered with
the adapter). This configuration provides support for up to 128 EIA-232 devices per PCI slot.
The ability to use synchronous attachments to any Remote Async Node provides even greater
flexibility in system configuration, allowing customers to use synchronous modems for long-distance
connectivity.
It is possible to use either V11/RS422 or V24/RS232 synchronous modems. However, it is not
possible to interpose more than one pair of such synchronous modems within this "daisy chain" of
RANs.
