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.
