I am indeed grateful to you for your help. A couple more questions, if you please answer.
1. Is 5B47 better than 5B37?
2. How to make connections of the module( you said I can use the module without backplanes?) there are many terminals (http://www.analog.com/en/other/ios-subsystems/5b37/products/product.html) If I do not use backplanes, then will there be still CJC ?
Thanks
