Which macrocontroller are you using?
The TS-8820 is the baseboard (non-computing component) of a signal-isolated industrial controller. Frequently used in building management and control applications worldwide, it offers a wide variety of features useful for power and access control, as well as several ADC inputs and isolated IO useful for various sensor and monitoring applications. This baseboard is frequently paired with the TS-4700, TS-4710/12/20 (collectively TS-47xx), and TS-4800 TS-SOCKET Computer on Module products to form a sensible and capable embedded computing platform dedicated to industrial system control and monitoring. Documentation for this product is split into three categories based on the compatible TS-SOCKET computer-on-modules for better clarity. Please choose the class of Computer-on-Module you are using in conjunction with the TS-8820 from the selection above.
