- To use the full input capacity of the SCU series, (12 DI), you must use the device in a double-address mode. When typically using them as a replacement for 7900 series the existing addressing usually restricts the use to single address mode. Refer to TCON312 for further information.
- Also be aware of I/NET system Compatibility, download TCON312 (Overview section) for further detail.
Regardless of which version of TAC I/NET software you use, you must load SLIs with updated software in order to properly communicate with the SCU.
