*3. Y002 is not available in FX
*4. High-speed output special adapters can be connected only to the FX
*5. To use Y002 and Y003 with a high-speed output special adapter, connect a second high-speed output
special adapter.
Note:
• To use an FX
special adapter.
• Differential line drive type outputs will be used for the outputs of the high-speed output special adapter.
