PK-88 OPERATING MANUAL COMMAND SUMMARY

CHAPTER 5 – COMMAND SUMMARY
5.1 Introduction
This chapter explains and illustrates the PK-88's commands. You will use some commands to
control the PK-88 under specific conditions, and others to specify the values of parameters
used in general operation.
The PK-88 is a 'command-driven' system; it does not provide 'menus'. You control the func-
tions of the PK-88 by typing single- or multiple character commands at your computer's key-
board.
We will use UPPER CASE in this chapter to show the commands, and lower case to explain
the text.
5.1.1 Entering Commands
Commands are entered after the Command Mode prompt:
cmd:
You will use English-like words or abbreviations to change the value of parameters and is-
sue instructions to the PK-88.
o Commands are either keywords or mnemonics (special abbreviations) made up of
strings of characters that you type.
You may never need to change the values of some parameters. However, these com-
mands give you maximum flexibility to adapt the PK-88 to your local environment and op-
erating conditions.
o Use either upper case (capital letters) or lower case (small letters) when typing
commands.
o End the command with a carriage return <CR> ( [
↵
] ). Carriage returns are not
shown in the examples below.
o Correct your typing mistakes or cancel the line completely before typing the final
<CR> of your command.
o See Chapter 3 for a discussion of line editing.
5.1.2 Command Responses
Whenever the PK-88 accepts a command that changes a value, the PK-88 responds with
the previously stored value. For example, assume that 'XFLOW' is 'ON' and you type
XFLOW OFF ; you will see the display:
XFLOW was ON
This message confirms that the value has been changed successfully.
5.1.3 Error Messages
If the PK-88 cannot understand what you have typed, you will see an error message in
plain language reporting the nature of the error.
