Remote workstation
attachment
Attachment of workstation located in remote sites to one or
more AS/400s located in a central location.
The 3494 manages information exchanges with the AS/400
system over a communication network.
Local processing for non-
programmable
workstations
A non-programmable workstation (NWS) is a workstation
which is incapable of processing information on its own.
Twinaxially attached workstations and printers are examples
of NWSs.
The 3494 can process keystrokes and field entries locally
without communicating with the AS/400. This processing
improves the response time for accepting and processing
keystrokes. When the information is ready for transmission
to the AS/400, the 3494 manages the flow of information
over the communication network.
Support for
programmable
workstations
A programmable workstation (PWS) is a workstation which is
capable of processing information independently of the
AS/400 and can also exchange information with the AS/400.
PCs running Client Access/400 are examples of PWSs. The
3494 supports attachment of PWSs and manages the SNA
LU 6.2 sessions established. Session can either be PWS
initiated or Host initiated.
Twinaxial workstation
attachment
Twinax attachment is provided for either 28 devices
expandable to 56 devices via a Twinax expansion adapter.
Communication network
interface options
The 3494 provides communications to the AS/400 through a
variety of network interfaces allowing communication to
different types of networks.

communication (Token
Ring and Ethernet)
The 3494 attaches to the LAN using the following
configurations:
AS/400 Attachment Configuration: This configuration
allows the 3494 to communicate with AS/400 systems using
a LAN. The 3494 and AS/400 system can be on the same
LAN or on separate LANs that are connected using bridges.
Gateway Configuration: This configuration allows PWSs
connected to the LAN to attach to the AS/400 through the
3494. This configuration is referred to as LAN Gateway
configuration since the 3494 serves as a gateway between
the LAN-attached workstations and the AS/400.
Gateway and AS/400 Attachment Configuration: The
3494 controller can be configured to support both AS/400
attachment and Gateway attachment. The same Ethernet
adapter can be used for both configurations.

created by the AS/400 system when using a LAN connection
to the AS/400. This capability also allows automatic
configuration on the AS/400 of the RWS controller and the
device descriptions of the 3494 attached NWSs. NWSs
(display or printers) that are attached to the 3494 via Twinax
do not have to be configured if the OS/400 operating system
is at least Version 3 release 1.
Alternate A/S400 System
Support
Each AS/400 connections can have up to three alternate
configuration. This allows the user to end a connection with
one AS/400 and establish a new connection with one of the
alternate AS/400.
AS/400 performance
monitor support
The 3494 supports the Performance Monitor, an AS/400
function that enables the AS/400 to request that the 3494
measures and reports information on the response time of
NWSs attached to it.
