5. Putting into Operation

Standard interface cables are used to connect external systems and devices to the
interface. To comply with EMC regulations double shielded cables must be used. The
cable length must not exceed 3 meters. Make sure at this time that none of the cables
shows any sign of damage.
After checking all connections the oscilloscope can be switched on. Both the oscilloscope
and the interface are now fully operational. Please note that the interface can only trans-
fer data while the oscilloscope is in storage mode (STOR.). In spite of that, the oscilloscope
can be used in the analogue mode at any time, of course.

5.1 Mechanical Operating Parameters Setting

Every time the interface is activated (when the scope is switched on), the default settings
(IEEE-488 (GPIB) = Address 1, RS-232 = 38400 Baud and CENTRONICS = Standard)
become active. Subsequently its operating parameters are newly defined by the settings
previously made with the two rotary switches SW1 and SW2. The default settings of
those ranges that are not effected by the mechanical setting of SW1 will be preserved.
Example:
If SW1 is set to "A" when the instrument is switched on, the CENTRONICS range (SW1=
8 – B) is selected. The default settings of the other ranges IEEE-488 (SW1 = 0 –3; Default
= Address 1) and RS-232 (SW1 = 4 –7; Default = 38400) remain unchanged.
If you wish to set another operation mode, just switch off the oscilloscope and make the
new settings at SW 1 and SW 2 resp. using a 2.5 mm screwdriver according to the table
of settings (see appendix), and switch the oscilloscope on again after a minimum time
of 10 seconds.

5.2 Electronic Operating Parameters Setting

The following description notes the differences, if the HAMEG Oscilloscope is supplied
with a pushbutton marked "PRINT":
5.2.1 After the instrument is switched ON and the self test has passed, "HO79
DETECTED" is briefly displayed.
5.2.2 The "MAIN MENU" additionally contains the menu item "HO79".
The software setting in the submenus of "HO79" select for port and language – such
as SW1 – used for documentation (see item 5.2.2.1 and 5.2.2.2). All other items regard
to additional information.
After calling "HO79" the following submenus and related software settings are
displayed:
5.2.2.1 LANGUAGE:
EPSON, HPGL, PCL and POSTSCRIPT.
5.2.2.2 PORT:
CENTRONICS, RS-232 and GPIB (IEEE-488).
5.2.2.3 HEADER:
HEADER ON, HEADER OFF and BORDER (as HEADER ON, but only
the outline of the HAMEG Logo is printed / plotted.
