card and an 8-port DB25 connector box, composed of eight asynchronous ports
from a single I/O card slot.
The main characteristics for this adapter are:
Data rates up to 115.2 Kbps per port
Fully buffered transmit and receive data
Single 78-pin connector for connection to 8-port DB25 connector box
Supports the following interface signals:TxD, RxD, RTS, CTS, DSR, DCD, DTR
and RI
Maximum EIA-232 distance supported is 62 meters (200 feet)
Requires one ISA slot
Maximum of three adapters of this type can be installed
Installation and configuration of this adapter is not automatically made by AIX;
proper operations must be followed by the system manager. DIP switches on the
adapter must be set correctly before configuring the adapter to the AIX operating
system. 6.4, “8-Port EIA-232 Asynchronous ISA Adapter (FC 2931)” on page 108
explains how to install and configure this adapter.
ISA 128-Port Asynchronous Adapter (feature #2933)
This adapter provides for a high concentration of asynchronous lines from a single
ISA bus slot. Two synchronous channels link the adapter to a maximum of eight
16-Port Remote Asynchronous Nodes (RAN) (feature #8130 in USA & Canada
only; feature #8134 World Trade). Each channel can support up to four 16-Port
RANs.
One 4.5 meter cable (feature #8131) is available to connect the adapter to the first
RAN on each channel. Additional RAN modules may be connected to each
channel in a “daisy chain” configuration, using either the 4.5 meter (15 foot) cable
(feature #8131) or the 23 cm (9 inch) cable (feature #8132). Customer-supplied
cables may also be substituted.
These are the main characteristics for this adapter:
Data rates up to 57.6 Kbps per port
Support to 128 ports per adapter
Supports the following interface signals:TxD, RxD, RTS, CTS, DSR, DCD, DTR,
and RI
Maximum EIA-232 distance supported is 62 meters (200 feet)
Requires one ISA slot
Maximum of three adapters of this type can be installed
Installation and configuration of this adapter is not automatically made by AIX;
proper operations must be followed by the system manager. DIP switches on the
adapter must be set correctly before configuring the adapter to the AIX operating
system. 6.5, “128-Port EIA-232 Asynchronous ISA Adapter (FC 2933)” on
page 111 explains how to install and configure this adapter.
