OPERATING INSTRUCTIONS
The 1258 can be controlled through the front panel or through one
of the rear panel control interfaces, GPIB, Ethernet, or RS-232.
Most operations can be performed from a remote computer,
however, the front panel interface must be used to configure the
remote interfaces, perform display specific operations, and to
obtain help on system operation.
configuration information is automatically saved if the unit is
powered off.
To save the matrix configuration and operating
modes during power off conditions, use either the 'Current' or 'Last
Configuration' PowerUp mode (see PowerUp Configuration for
details).
The front panel display has a screen saver feature that protects
display from ghost characters being permanently imprinted on the
screen due to prolonged inactivity. The display will automatically
enter the screen saver mode after 15 minutes of no activity on the
front panel.
The screen saver does not operate in diagnostic
mode. Remote commands are processed as normal during screen
saver mode. Software version and matrix configuration information
can be found on the About screen as shown in Figure 4-1.
