All fou r enable signals m u st be p rovid ed by the cam era on each Channel Link chip . All u nu sed d ata bits
m u st be tied to a know n valu e by the cam era. For m ore inform ation on im age d ata bit allocations, refer to
the official Cam era Link sp ecification located at http :/ / m v.d alsa.com .
Camera Control Signals
Fou r LVDS p airs are reserved for general p u rp ose cam era control. They are d efined as cam era inp u ts and
fram e grabber ou tp u ts. Cam era m anu factu rers can d efine these signals to m eet their need s for a
p articu lar p rod u ct. The signals are:
• Camera Control 1 (CC1)
• Camera Control 2 (CC2)
• Camera Control 3 (CC3)
The cam era u ses the follow ing control signals:

Communication
Tw o LVDS p airs have been allocated for asynchronou s serial com m u nication to and from the cam era and
fram e grabber. Cam eras and fram e grabbers shou ld su p p ort at least 9600 bau d . These signals are
• SerTFG—Differential pair with serial communications to the frame grabber.
• SerTC—Differential pair with serial communications to the camera.
The serial interface w ill have the follow ing characteristics: one start bit, one stop bit, no p arity, and no
hand shaking. It is recom m end ed that fram e grabber m anu factu rers su p p ly both a u ser interface and a
softw are ap p lication p rogram m ing interface (API) for u sing the asynchronou s serial com m u nication p ort.
The u ser interface w ill consist of a term inal p rogram w ith m inim al cap abilities of send ing and receiving a
character string and send ing a file of bytes. The softw are API w ill p rovid e fu nctions to enu m erate board s
and send or receive a character string.
Power
Pow er w ill not be p rovid ed on the Cam era Link connector. The cam era w ill receive p ow er throu gh a
sep arate cable. Cam era m anu factu rers w ill d efine their ow n p o w er connector, cu rrent, and voltage
requ irem ents.
