Camera Link cable quality and length
The m axim u m allow able Cam era Link cable length d ep end s on the qu ality of the cable u sed and the
Cam era Link strobe frequ ency. Cable qu ality d egrad es over tim e as the cable is flexed . In ad d ition, as the
Cam era Link strobe frequ ency is increased the m axim u m allow able cable length w ill d ecrease.
The Falcon2 cam eras are cap able of d riving cables less than 7 m etres in length. We d o not gu arantee good
im aging p erform ance w ith low qu ality cables of
any
length. In general, w e recom m end the u se of high
qu ality cables in lengths for any cable length.
Recommended Cables
We recom m end the u se of high -qu ality m ini-CL cables. Teled yne DALSA has 3 m eter and 5 m eter cables
available as accessories. Contact Cu stom er Su p p ort.
Input Signals, Camera Link
The cam era accep ts control inp u ts throu gh the m ini-Cam era Link SDR-26F connector. The cam era ship s
in internal sync, and internally p rogram m ed integration .
EXSYNC (Frame Readout Trigger)
Fram e rate can be set internally u sing the serial interface. The external control signal EXSYN C is op tional
and enabled throu gh the serial interface. This cam era u ses the falling ed ge of EXSYN C to trigger p ixel
read ou t.
The EXSYN C signal tells the cam era w hen to integrate and read ou t the im age. It can be either an
internally generated signal by the cam era, or it can be su p p lied externally via the serial interface.
Dep end ing u p on the m od e of op eration the high tim e of the EXSYN C signal can rep resent the integr ation
p eriod .
Output Signals, Camera Link Clocking Signals
