What's Included: Moxa NPort 5610-16 16-Port Serial Device Server RS-232/422/485Functionality: Sold as-is. We have not fully tested this unit however there seems to be some issue with it. When powered on and we go through the menu it beeps after a few seconds and goes back to the home screen. We also cannot see what firmware version is loaded so we think this may be the issue and it needs to be loaded/updated to the most recent version. Due to this we are selling as is and for parts/repair.Cosmetic Condition: Decent - General wear and tear around the unit.Return Policy: We offer free 30-day returns on all items for any reason. (Excludes For/Parts or Repair items unless otherwise specified)
