VD15-0+/-… LBA-7XX
Connect the digital data signals to these inputs. VD11 is the MSB and VD0 is the LSB. Connect
the LSB from your camera to VD0. Unused connections must always involve the MSB’s. VD+
must be a logic high to denote a true condition of a data bit. Set the Pixel Bits value to the
number of data connections supported. Note: If the output from your digital camera is in a
signed two’s compliment data format, connect the sign bit to the bit just above the cameras
MSB data bit. The Pixel Bits entry should be a negative value for signed data. For example: If
your data is a 12 bit signed two’s compliment format, enter a -12 for the Pixel Bits.
At the present time 16 bit cameras are supported as 15 bit devices, VD15 is not usable. If you
are connecting a 16 bit camera connect the 15 MSB’s to VD0 through VD14
COM
A number of signal common, or ground, connections should be made between your camera and
the LBA. Although not required for operation, an outer case-to-case shield connection is also
recommended.
The above connections are the minimum requirements for successful interfacing of a digital
camera to the LBA-PC.
The following additional signals are outputs from the LBA-400/500PC models that provide
control for an electronic shutter, if your camera is so equipped.
SHT#… LBA-400/500 ONLY
These three signal outputs are available to control an electronic shutter. For these signals to
become operational, the Shutter check box must be checked. You can enter the Shutter
speeds in the supplied dialog box. Be sure to save the camera configuration into a .cam file
once you’ve completed these entries.
RST… LBA-400/500 ONLY
This signal output is reserved and has no function at this time.
Special Jumper Cutting Requirements: LBA-400/500 ONLY
Special circumstances can arise if your digital camera has a contrary number of digital outputs
than the LBA-400/500PC can support.
• The LBA-400PC can support a maximum of 10 data bits.
• The LBA-500PC can support a maximum of 12 data bits.
If your camera has more digital outputs than the LBA has inputs, use the upper MSB’s from
your camera, starting with VD11 on the LBA.
