The AETA can support data communications over either the USB or Serial ports. The AETA will automatically detect if a Computer is plugged into the USB port and switch to USB port operation. Please note, it is possible to only operate either the USB or Serial port at any one time, i.e. the AETA will not operate both ports at the same time.
If you have forced the AETA to use the USB port but wish to change back to automatic detection mode, then:
Lift the Phone handset, you will hear a dial tone.
Dial
#28#0#
You will hear a confirmation tone.
Hang up the Phone Handset.
Reset the AETA by removing the power plug pack
lead and the ISDN (S) lead for 5 seconds.
If
you are using Automatic detection mode but
want to force the AETA to use the USB port then
follow the steps above but dial #28#2#
instead
of #28#0#.
If you want the AETA to use the Serial port only, then dial #28#1# in the sequence above.
Warning: Removing power from the AETA will disrupt all communications via the AETA. This includes all EFTPOS and phone connections.
