4.6 Interfaces for the Laser and
Peripheral Equipment

4.6.1 LASER Connector

The LASER Connector is a 15-pin D-SUB connector
(female). It is located on the slot cover of the
RTC6 PCIe Board, see Figure
The pin-out is shown in Figure

Notice!
• If you want to use the RTC6 PCIe Board in
conjunction with laserDESK, observe the
following:
– laserDESK uses additional pins on the
EXTENSION 1 Socket
to control the laser.
– Refer to the extended documentation for
connecting the laser. Refer to laserDESK
online help
(alternatively available from SCANLAB or in
laserDESK-zip, which can be downloaded
from the SCANLAB website).

Laser Control Signals

Laser Control Signals are LASERON, LASER1 and
LASER2. They are digital TTL level signals and are
referenced to GND2.
Laser Control Signals LASER1 and LASER2 differ
depending on the set laser mode, see following table
and the timing diagrams in
Control", page 184.

On RTC6 PCIe Boards with

galvanically decoupled from GND
RTC6 PCIe Boards without
Converter", GND2 are GND identical, see
"Options", page 38.
For the maximum current load see
"Technical Specifications – RTC6 PCIe
page 873.
Al Laser Control Signals can be set by
set_laser_control to either active-LOW or
active-HIGH logic. "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 TTL laser control signal level according to the
specifications of your laser control. Observe the
documentation of your laser.

With RTC6 Ethernet Boards GND is the ground at the
