Basic Relay Operations
Making Simple Settings Changes
Note that some settings classes have only one instance and you do not specify
the instance designator when accessing these classes. An example is the
Global settings class. You can view or modify Global settings with a
communications terminal by entering SET G as shown in the ASCII
Command column of Table 10.4. The relay presents the Global settings
categories at the SET G command; no instance numbers follow SET G.
Conversely, the Port settings command has five instances (PORT F, PORT 1,
PORT 2, PORT 3, and PORT 5). To access the PORT 1 settings, type SET P 1
<Enter>. If you do not specify which port to set, the relay defaults to the
active port (the port you are presently using).
The Group settings can have the optional one-letter acronym S attached to the
command; you can enter SET 1 or SET S 1 for Group 1 settings, SET 2 or
SET S 2 for Group 2 settings, etc. If you do not specify which group to set, the
relay defaults to the present active group. If Group 6 is the active group, and
you type SET <Enter>, for example, you will see the settings prompts for the
Group 6 settings.
Settings: Terminal
When you change settings (with any SET command) from a terminal, the
relay shows the setting category, prompt, present value, and action prompt.
Figure 10.10 shows two settings examples: multiple-line settings (SID and
RID) and an in-line setting (NUMBK) for relay Global settings from Access
Level P (protection). The relay prompts you for input by presenting an action
prompt. You have many options for navigating the settings at the
? action prompt.
Table 10.5 lists the operations possible from a settings action prompt.
