The following instructions apply to CPU Units with lot numbers of 3180O (August
2000) or earlier.
The previous CPU Units do not detect a Programming Console connected to the
peripheral port, and SW2 of the DIP switch was used to set either "Programming
Console" or "Other device."
SW2 Setting
Setting
OFF Programming Console connected to peripheral port.
ON Device other than Programming Console connected to peripheral port.
SW1 Setting
Setting
OFF Use PC Setup settings for RS-232C port (DM 6645 to DM 6649).
ON Use default settings for RS-232C port.
The relationship between the PC Setup settings, the setting of SW2, and the
startup operating mode for previous CPU Units is shown in the following table.

Note 1. The default setting for DM 6600, bits 06 to 15 is 00 Hex, i.e., according to the
communications switch on the front panel. If SW2 is set for connecting a de-
vice other than a Programming Console to the peripheral connector, the
CPU Unit will start in RUN mode as soon as power is turned ON. Be sure that
adequate precautions are taken to ensure safety.
2. If SW2 is for connecting a device other than a Programming Console to the
peripheral connector, the CPU Unit will start in RUN mode as soon as power
is turned ON even it a device is connected to the RS-232C port. Be sure that
adequate precautions are taken to ensure safety.
