Camera Control Signals

Fou r LVDS pairs are reserved for general pu rpose cam era control. They are d efined as
cam era inpu ts and fram e grabber ou tpu ts. Cam era m anu factu rers can d efine th ese signals
to m eet their need s for a particu lar prod u ct. The signals are:
• Cam era Control 1 (CC1)
• Cam era Control 2 (CC2)

Communication
Tw o LVDS pairs 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 pport at least 9600
bau d . These signals are
• SerTFG—Differential pair w ith serial com m u nications to the fram e grabber.
• SerTC—Differential pair w ith serial com m u nications to the cam era.
The serial interface w ill have the follow ing characteristics: one start bit, one stop bit, no
parity, and no hand shaking. It is recom m end ed that fram e grabber m anu factu rers su pply
both a u ser interface and a softw are application program m ing interface (API) for u sing
the asynchronou s serial com m u nication port. The u ser interface w ill consist of a term inal
program w ith m inim al capabilities of send ing and receiving a character s tring and
send ing a file of bytes. The softw are API w ill provid e fu nctions to enu m erate board s and
send or receive a character string.
Power
Pow er w ill not be provid ed on the Cam era Link connector. The cam era w ill receive pow er
throu gh a separate cable. Cam era m anu factu rers w ill d efine their ow n pow er connector,
cu rrent, and voltage requ irem ents.
