2.4.3 Trigger 
Out 
Connector J2 (J5 on LBA-3/4/500 frame grabbers) pin 3 is the Trigger Out signal.  This signal is 
factory set to output +5Vdc pulses.  You can change this signal to +12Vdc level pulses by moving 
Jumper E1 (E4 on LBA-3/4/500 frame grabbers) to bridge pins 2-3.   
 
Note:  Jumper E1 (E4) controls the output signal level for both Trigger Out and Pass/Fail Out.  Jumper position 1-2 
yields a +5Vdc level; position 2-3 yields a +12Vdc level. 
 
2.4.4 Pass/Fail 
Out 
Connector J5 (J2 on LBA-7XX frame grabbers) pin 1 is the Pass/Fail Out signal.  This signal is 
factory set to output +5Vdc pulses.  You can change this signal to +12Vdc level pulses by moving 
Jumper E1(E4) to bridge pins 2-3.  To enable this signal and select its mode of operation see the 
Pass/Fail menu topic. 
 
Note:  Jumper E1 (E4) controls the output signal level for both Trigger Out and Pass/Fail Out.  Jumper position 1-2 
yields a +5Vdc level; position 2-3 yields a +12Vdc level
 
2.4.5 Trigger 
In 
Connector J2 (J5 on LBA-3/4/500 frame grabbers) pin 2 is where you apply the Trigger In signal.  
This input must be only a positive voltage with respect to ground.  But you can pulse it with either a 
high going or a low going pulse.  You can program the Trigger In Polarity to respond to either a 
positive (rising) or negative (falling) edge of this input signal. 
 
2.4.6 Video 
In 
The BNC connector (not shown above) is where you input either RS-170 or CCIR formatted black and 
white video.   The video input is terminated into 75 ohms.  This is Camera input number 1.  If you 
have purchased the 4 camera option, three additional BNC connectors are provided on a separate 
bracket assembly.  These BNC connectors provide inputs for cameras number 2, 3 and 4 (top to 
bottom). 
 
2.5  Camera Control Cables 
Many cameras shipped by Spiricon will be supplied with a Camera Control Cable.  Connect this cable 
between the camera and connector J1, (J3 on LBA-3/4/500 frame grabbers) the upper 9-pin D-sub 
female.  This cable will usually provide power to the camera, as well as permit the LBA-PC to control a 
camera’s electronic shutter, if it has one.  Cameras that derive power from a source other than the LBA-
PC will not usually be supplied with this cable. 
If you are using the 4-camera option, any additional cameras must be powered from an external 
source.  To provide control of the shutter of any additional cameras, a special cable must be made that 
connects all of the shutter inputs of the cameras in parallel.  If you plan on using the automatic camera 
sequencing you may also need a special cable to synchronize (genloc) the cameras.
