AMCI AMCI SD4840E2 Ethernet Integrated Stepper Drive - Open Box Read description!!!

Please read! I have recently bought a pallet of goods. This was on here. I honestly have no idea what it is. I saw it recently sold open box for $1250. I am not sure of the condition as I stated I really don't know what this is. Therefore I'm listing at $999.99. I am not sure of how it works or if there is a way to test it. So it will be sold as -is no returns. I have put a best offer out there and I'm open to what you are offering. Thank you!
