Dalsa Xtium2-CLHS PX8 - Note 3.3: Interfacing to a Line Driver (also Called Open Emitter) Output; Note 3.4: Interfacing to an Open Collector Output

86 • Technical Specifications Xtium2-CLHS PX8 User's Manual
• The TTL shaft encoder ground, the bias voltage ground, and the Xtium2-CL PX4 computer
system ground must be connected together.
• DC voltage for the RS-422 (-) input can be generated by a resister voltage divider.
• Use a single battery cell if this is more suitable to your system.
