You may be right Andrew and I could be wrong but as far as I can tell that is a generic box sold by Allonis and is the exact same box I'm already using. The problem appears to be with the driver setup. The AddController command isn't populating the Device Address field for some reason. I'm really reluctant to buy another box until Allonis verifies there is something proprietary about their box and I need to use it. Then I'll gladly buy one. But I don't want to buy it not knowing for sure that will fix my problem. Thanks for your input.
