1.4.3 Baudrate setting

Baudrates from 1200 up to 115200 can be selected by switch SW2.

1.4.3.1 Manually started documentation

Prerequisite switch SW1 is in position "4, 5, 6 or 7" and switch SW2 is set to values
between "0" and "7", the documentation can be started by briefly pressing the "start"
push button or by the corresponding command received by the IEEE-488 port.

1.4.3.2 Automatic documentation

This mode is present if switch SW1 is set to values between "4 and 7" and switch SW2
is set to values between "8" and "F". Oscilloscope and interface must be prepared for
automatic documentation in the following manner. First the oscilloscope must be set to
SINGLE mode and thereafter the RESET pushbutton must be pressed briefly to activate
the trigger unit. After a trigger event has started the signal capture and the recording
is completed (RESET- LED dark), the "start" pushbutton located on the interface must
be pressed to cause documentation. Thereafter the oscilloscope trigger unit is reset
automatically. From now on each trigger event causes documentation.
In this mode the interface has to detect the presence of a completed recording. Each
query causes the "RM"-LED to light.

1.5 PRINTER- (CENTRONICS) Port

Not for HAMEG Graphic-Printer!
This unidirectional port enables byte-serial data transmission for documentation by
devices (e.g. printer) which are equipped with a CENTRONICS connector. Data transfer
in the sense of the terminology used in this description cannot be performed via this port.
The connections of the PRINTER port (25pole D-Sub female) can be seen in the appendix.
The printer cable must be screened.

1.5.1 Hardware configuration

If switch SW1 is active (not overwritten by software configuration) and set to 8, 9, A or
B. The PRINTER port can be used for documentation purposes.

1.5.2 Software configuration

The setting of switch SW1 can be overwritten by a suitable command received by the
IEEE-488 or RS-232 port (data transfer). Subsequently the mechanical setting of SW1
becomes inactive until the oscilloscope is switched off for approx. 10 seconds.
1.5.3.1 Manually started documentation
Prerequisite switch SW1 is in position "8, 9, A or B" and switch SW2 is set to"0, 2, 3,
4, 5, 6, or 7", the documentation can be started by briefly pressing the "start" pushbutton
or by the corresponding command received by the IEEE-488 or the RS-232 port.
1.5.3.2 Automatic documentation
This mode is present if switch SW1 is set to values between "8 and B" and switch SW2
is set to values between "8" and "F".
Oscilloscope and interface must be prepared for automatic documentation in the
following manner. First the oscilloscope must be set to SINGLE mode and thereafter the
