8.2 Changing The Jumper
Settings
TTL Laser Signal Level
The RTC
®
4 board permanently generates the
following laser signals (also see page 32 through
page 37 ):
• LASERON
• LASER1 / Q-Switch
• LASER2 / FirstPulseKiller
• Stand-By1, Stand-By2
All laser signals can be set to either active-low or
active-high logic via jumper X10 :
Active-low means that a logical 1 ("Laser On", for instance)
is represented by a LOW level (0 V, TTL). Active-high means
a logical 1 is represented by a HIGH level (+5 V, TTL).
Set the jumper according to the specifications
of your laser control. Please refer to the
documentation of your laser.
Laser / Analog Output Ports
(9-Pin Laser Connector)
The signals at pins (2) and (4) of the 9-pin
laser output port connector (see
figure 30 on
page 59 ) must be selected via jumpers X6 , X7 and
X3. The following table summarizes the jumper
settings. For further information please refer to
section
"How To Set The Jumpers" , next.
How To Set The Jumpers
Jumpers X6 and X3
If you want to use the signal ANALOG OUT1
(e.g. for lamp current control), set the jumper
X6 to position 2-3. Then specify the output
voltage range with the Jumper X3 (see table).
Alternatively, the output signal at pin (4) can be
set permanently to +5 V (jumper
X6 in position
1-2). In this case, jumper X3 can be ignored.
Jumper X7
If you need the TTL signal LASERON for laser
control, set the jumper
X7 to position 1-2.
If your laser requires only the signals LASER1
and LASER2, you can use pin (2) for the signal
ANALOG OUT2 instead. To do this, set the
jumper
X7 to position 2-3.
Note: The ANALOG OUT2 signal is also available
via the MARKING ON THE FLY connector.

For a description of the analog output signals please
refer to
chapter "Analog Output ports", page 52 .
Caution!
• The jumpers are soldered junctions. If you need
to change the jumper settings, you’ll have to
use a soldering-iron.
Please be careful not to damage the
electronics on the board!
