The VersaPort retains the most recent mode-setting (Manual or Auto) in which it was
operated. In Manual mode, the VersaPort rejects high level commands such as "Stage"
and "Home". In Auto mode, the VersaPort rejects low level commands, such as individual
motor diagnostic commands.
If configuring or servicing the VersaPort, operation may be switched into Manual mode. If
not switched back to Auto mode after completing the service work and power is not reset,
the VersaPort may reject commands from the Process Tool when placed in operation.
In general, while in Manual mode, the VersaPort will reject any command that requires an
Auto mode setting, regardless of the command that is issued through SECS, ASCII, or
parallel Host control signals.
Either ISIM or the Process Tool can issue an "Auto" command to return the VersaPort
operation to Auto mode. This command is available through both SECS and ASCII
interfaces, provided that the Host software has included the command in its
implementation. Resetting power to the VersaPort also automatically places it back in
Auto mode. A "Reset" command, however, only clears any pending error and does not
return the VersaPort to Auto mode.
After performing service work on the VersaPort, it should be returned to Auto mode and
exercised a few times with the Auto mode "STAGE" and "HOME" commands to confirm
proper operation. If the debug option had been enabled earlier during trouble-shooting,
disable the debug prior to returning operation back to the Process Tool.
