Problem	Resolution

Unit doesn’t spin	Verify power connection and polarity.
	Verify proper voltage – should be 16 volts
	drawing about 3-4 amps.
	Remove bottom cover and check inline 10 amp fuse.
	Replace if necessary. Model No. ATM-10.

Unit spins but no data	Verify Ethernet wiring.
	Verify packet output with another tool
	(e.g. Ethereal/Wireshark).

No serial communication	Verify RS-232 cable connection.
	Unit must be active and spinning for
	RS-232 update.
	It may take several tries for the update
	to be effective.
