7. Operation
The LinkUp 5294 operates in six different modes:
1.
Connect Mode —
typically the operating session encountered prior to accessing the others; allows
you to sign on to the LinkUp 5294.
2.
Port Test Mode —
allows you to perform several diagnostic and information functions: Interface
Signal Display, Character Display Test, and Character Echo Test.
3.
System Management Mode —
allows you to perform the following diagnostic and information
functions:
• Interface Signal Display (similar to the function in Port Test Mode)
• Sync Port Address Trace
• Async Port Trace
• Product Configuration and Levels Display
• Sync Port Trace
• Character Display Test (also provided in Port Test Mode)
• Character Echo Test (also provided in Port Test Mode)
• LU and Async Port Summary
• Remote Reset
• SNA/SDLC Counters
4.
Configurator Mode —
enables you to define the operating and environmental characteristics in
which the LinkUp 5294 will function.
5.
Emulation Mode —
the standard operating session encountered by a terminal operator
communicating with the System/3X host.
6.
Setup Mode —
lets you restore the factory default configuration parameter values defined in the
LinkUp 5294.
7.1 Operating Requirements
To establish an operating session with the LinkUp 5294 the following hardware and software
requirements must be met:
7.1.1 C
ABLES AND
C
ONNECTIONS
As discussed in
Chapter 5
, all LinkUp 5294 connectors (ports) support a standard RS-232C interface.
Each device or 3X host Integrated Communications Adapter (ICA) must be connected to the LinkUp
5294 by a shielded RS-232C cable.
When a terminal, printer, personal computer, or 3X host is attached directly to a LinkUp 5294 port, it is
called a Local connection; when they are attached by modems, it is called a Remote connection.
(Remote connections can be through switched or dedicated lines.)
