"Automatic reset" means that, when an error occurs, no error message
will be displayed and the next command will be executed when received.
"No Automatic reset" means that, when an error occurs, an error mes-
sage will be displayed and operation will stop. If an RS-232C or RS-422A
Interface Unit is mounted, the host will be notified that an error occurred
and there will be no automatic reset regardless of whether this pin is set
to ON or OFF.
If this pin is turned OFF, then the host RUN input will be enabled and PT
operation can be controlled by external sequences. If this pin is set to
ON, the PT will operate but when the host RUN input turns OFF, Host
Error will be displayed and operation will stop.
This pin is reserved for system use, and must remain set to ON. If this
pin is set to OFF, messages will not display properly.
This pin designates the bits for lamp and touch switch display control for
when Host Link Interface Units or C200H Host Interface Units are used.
---
"Mode change" refers to changing between the System Menu and Trans-
mit Mode, Maintenance Mode, or RUN Mode. When an RS-232C or
RS-422A Host Interface Unit is used, mode changes can be prohibited
by means of a command from the host.
---
The NT600M-LK201 can be used as either a Host Link Interface Unit or
an RS-232C Interface Unit. Operation will not be possible if the setting of
this switch does not match the communications system. If another type
of Host Interface Unit is mounted, this setting will be ignored.
Turn off the power supply to the PT and mount the System ROM into the PT
as described below.
Open the System ROM cover on the back of the PT.
