This is an RBS50 Satellite converted from an RBR50. It functions exactly like a regular RBS50 but has a blue top instead of grey. The last pic shows the status of the unit connected on my network. Has latest firmware on it, and will update firmware as a normal RBS50. If you hard reset it, it stays as a RBS50. The satellite is in poor external condition and is a little sticky to the touch, but functions perfectly. Includes 3rd party AC adapter.
