Connecting TTL Signals to LDVS Inputs
•
LVDS/RS422 (-) input is biased to a DC voltage from +1 to +2 volts.
•
This guarantees that the TTL signal connected to the LVDS/RS422 (+) input will be detected as a
logic high or low relative to the (-) input.
•
The TTL shaft encoder ground, the bias voltage ground, and the PC2-CamLink computer system
ground must be connected together.

3 Examples on Generating a DC voltage for the LDVS (-) Input
•
DC voltage for the LVDS/RS422 (-) input can be generated by a resister voltage divider.
•
Use a single battery cell if more suitable for your system.
•
A DC voltage (5 or +12) is available on DB-15 connector (J2).
