CHAPTER 4: Operation
4. Operation
The first part of this chapter,
Section 4.1
, gives you some guidelines that you
should follow to make sure your ServSwitch Professor works properly with your
equipment.
Section 4.2
summarizes the Professor’s keyboard commands, and
Section 4.3
describes these commands in detail. Keep in mind that only the instructor’s System
Control Module (SCM, our product code KV780A) responds to commands;
Student Modules (STMs, our product codes KV781A and KV782A) ignore
commands.
NOTES
To start any ServSwitch Professor keyboard command, you must press
and release the left Control Key ([Ctrl]). Pressing and releasing [Ctrl]
cues the Professor to expect command characters from the keyboard.
You then have two seconds in which to start entering a valid command.
If no command is begun within two seconds or if an invalid command is
entered, the ServSwitch Professor aborts the command.
When entering commands that contain numbers or math symbols,
use only the numeral keys located at the top of your alphanumeric
keyboard. Numbers and symbols entered from the numeric keypad to
the right will not be recognized as valid.
Commands are not case-sensitive.
You
must
press the [Enter] key to complete any command that
requires a numeric operand.
4.1 Guidelines for Using the ServSwitch Professor with Your Equipment
4.1.1 CPU
S
Use only IBM PC/AT or PS/2 or 100% compatible machines. The ServSwitch
Professor does not support IBM PC/XT™ or compatible machines. It does not
support machines that output CGA or EGA video.
4.1.2 M
OUSE AND
K
EYBOARD
When you power up your ServSwitch Professor system, make sure that your CPUs,
mice, and keyboards are properly cabled to each Professor. When you boot up
your CPUs, the Professors to which they are connected should already be ON. (You
should be able to freely disconnect and reconnect a mouse or keyboard from a
ServSwitch Professor while the Professor is ON, but if you experience problems
when you do this, issue the Reset command
[CTRL] R
—see
Section 4.3.24
).
