Prior to changing a fuse, turn off the electrical circuit or completely disconnect the camera.
Make certain that no dangerous condition exists before restoring power. Replace the fuse with a
fuse that is of the same rating and proper for the circuit. Never use anything other than a fuse of
proper rating.
3.4 Serial Communications
For serial communications, there are several choices available to the installer and the camera
user. If the camera is configured for RS-232 protocol, then it may be directly attached to a PC or
laptop running the FLIR Camera Controller graphical user interface (GUI) software, which is
included with the camera or downloaded from the FLIR website.
If the camera is configured for RS-422, then a communication protocol converter (also known as
a serial 232-422 converter) can be used to connect to a laptop or PC running the appropriate
GUI software, allowing a longer cable run.
The following diagram illustrates these communication options.

Warning!
Failure to disconnect power to the camera while replacing a fuse could result in
accidental injury or death or could damage the camera.
