Operation
AT3-6ME Interface Adapter D-9
Upon power up, the system goes through power up diagnostics. The terminal displays the
diagnostics sequence. Upon successful self test the unit is available for operation. The terminal will
display the actual set up of the system represented by the DIP switches (see Table D-6). If the
configuration was overwritten through the TTY, the terminal will display the actual set up that could
be different then the dip switch setting.
