I recently purchased the ELKM1 PCSPIM and a bunch of Simply Automated UPB Transceivers. I installed one switch and I am realizing that I cannot configure all of this with the Elk alone. Is this correct? I don't know why I thought I would be able to. Do I need to comfigure my devices seperately with Upstart? I guess I need to buy a CIM also? Am I on the right track?
