How can I power on my module?
What will I find in my module?
Off-the-shelf products are shipped with a standard in-house-developed software. The definition of standard, in this case, is "the environment which SECO adopts for validation". Anyway, custom in-house-developed __ software with different defaults can be built. Contact your reference sales for further information.
