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.
1.6 RS-232 connect through mode
As mentioned in section ”software”, the interface
HO79-6
receives and transmits
commands defined in the SCPI standard.
After mounting the interface at the rear of the scope, the scope RS-232 connector is not
accessible. The connect through mode enables direct access to the oscilloscope‘s RS-
232 connector and to make use of software written with oscilloscope commands.
The switch settings for RS-232 connect through mode are: SW1 = 8 and SW2 = 1.
In this mode the IEEE-488 and the PRINTER port are switched off. No facility of the RS-
232 mode as described from item 1.4.1 to item 1.4.3.2 is available.
2. Switch 1 (SW1)
The interface can transmit signal data via each port in 4 formats (languages):
Post Script (in connection with a Post Script printer)
HPGL (in connection with a HPGL plotter or printer)
PCL (in combination with an ink- or laser printer)
EPSON (in combination with a 9 or 24 dot matrix printer)
2.1 Output language- (data format) and port setting
SW1 is for port and language setting:
0:
IEEE-488, Post Script
1:
IEEE-488, HPGL
2:
IEEE-488, PCL
3:
IEEE-488, EPSON
4:
RS-232, Post Script
5:
RS-232, HPGL
6:
RS-232, PCL
7:
RS-232, EPSON
8:
CENTRONICS, Post Script
9:
CENTRONICS, HPGL
A: CENTRONICS, PCL
B: CENTRONICS, EPSON
3. Switch 2 (SW2)
This switch enables the selection of additional parameters.
3.1 IEEE-488 mode
Switch SW2 is for mode and address selection on condition that IEEE-488 mode is
present. If switch SW1 is not switched to IEEE-488 mode the address 1 is automatically
chosen (default).
