The 5494 is the remote communications controller for the AS/400® system. It manages the operation of workstations that are attached to the 5494 and provides the connection to the AS/400.

The 5494 can attach to an AS/400 system through wide area connections (SDLC, Frame Relay, X.21 and X.25), Ethernet orToken-Ring LANs.

The base 5494 Model EXT allows twin axial attachment for up to 28 non programmable or programmable devices(workstations and printers). It also provides communication access to an AS/400 system, using an EIA 232, a V.35 or an X.21 interface cable.

Protocols supported include SDLC, X.21, X.25 and Frame Relay. Many other protocols can also be bridged. The front panel of the 5494 contains a21-key keypad and a 16-position LCD that provide direct management capabilities.

Together they can be used to check device status, input date and time parameters, look up and display error codes or run concurrent diagnostics.

By accessing these functions directly from the 5494, you can eliminate the need, in most cases, for a workstation to be installed close to the controller.
