7.4 Pelco Keyboard Control (SR-100 and SR-100P only)
The SR-100 and SR-100P cameras can also be controlled with a universal keyboard controller
(for example, a Pelco KBD300A) using the Pelco D protocol. An example of the user commands
for use with the KBD300A is shown in section 10.0 KBD300 Commands
.
Note: The SR-Series cameras come pre-configured for either RS-232 or RS-422 communication
from the factory. Use with a Pelco-compatible keyboard requires RS-422. The baud rate for the
camera must match the keyboard (the Pelco KBD300A operates at 2400 baud only). The
correct Pelco device ID (also known as Pelco address) must be used, and by default the FLIR
camera also responds to device ID 99. Both the baud rate and the Pelco address may be
changed using the TVIS-7 User Interface GUI. The default rate for the SR-100 camera is 2400
baud and the SR-100P default is 19200 baud.
7.5 Flat Field Correction (FFC)
Periodically the image will momentarily freeze for a fraction of a second while the camera
performs a flat field correction. A shutter activates inside the camera and provides a target of
uniform temperature, allowing the camera to correct for ambient temperature changes and
provide the best possible image. Through the software user interface, the frequency of the FFC
can be modified.
