AS/400

Prompt

AS/400

Parameter

5494

AS/400 Value

5494 Value

Notes

Field

Subfield

Link type

LINKTYPE

*X21

5494 configuration values must
match the values specified for
the LINKTYPE parameter on
the CRTCTLAPPC command.

Select 2 for X.21 network
connections.

Station
address

STNADR

Values specified in the AS/400
controller description and for
the 5494 Remote Control Unit
must match. This value must
also be specified as the last 2
digits of the AS/400 EXCHID
parameter.

Example: Connecting AS/400 to a 5494 controller connected by X.21

Configuration parameters must be coordinated when you connect an AS/400 system to a 5494 controller.

The following diagram shows the AS/400 parameters and 5494 parameters that need to match when you
use X.21.
