4.1.5.1 Interface Converter
(Accessory)
A quick and easy way to connect the
pyrometer with a PC is to use an inter-
face converter or a connecting cable
with integrated interface converter (see
). Depending on the
operating system, suitable drivers are
installed automatically or can be found
on the CD supplied with the software
SensorTools
in the directory Drivers
FTDI_USB_COM, or after installing
SensorTools
in the installa-
tion directory (updated driver for Windows from the FTDI website:
http://www.ftdichip.com/Drivers/VCP.htm
).
To achieve the maximum transfer speed, it is absolutely necessary to change the latency time in the
advanced connection settings from 16 ms to 1 ms (settings in the Control Panel
device manager
Ports (COM & LPT)
USB Serial Port
Port Settings
Advanced
Latency Timer (at BM options)).

4.1.6 Shielding
Orange:
To meet the requirements for electromagnetic compatibility (EMC), only shielded cables
should be used. The shield of our connection cable is connected to the pyrometer side in the plug hous-
ing, on side of the connecting wires (voltage source) it remains open to prevent ground loops.
4.1.7 Camera Module
Devices with camera module as alignment are
equipped with an additional connector at the
rear (Lemo connector) for the output of the
camera signal (standard FBAS signal). Cable
