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 th ese 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)
• Camera Control 4 (CC4)
The H S-xx u ses the follow ing cam era 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 w ith serial communications to the frame grabber.
• SerTC—Differential pair w ith 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 s tring 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 ow er connector,
cu rrent, and voltage requ irem ents.
