Operating Modes Section 5-2
5-2-3 Startup Mode
The operating mode that the CQM1H starts in when power is turned ON
depends on the following three factors: The setting of pin 7 on the DIP switch
on the front of the CPU Unit, the PC Setup, and whether or not a Program-
ming Console is connected. The startup mode for different combinations of
these factors is shown in the following table.
Note The startup mode will depend on the setting of pin 7 on the DIP switch and the
type of device connected, in the way shown in the following table:
Note The following table shows the relationship between the startup mode and con-
necting cable when a device other than a Programming Device is connected.
5-2-4 Operation without a Battery
Operation is still possible when there is no internal battery, or the internal bat-
tery has expired, by writing the required data (user program, PC Setup, etc.)
to a Memory Cassette. In this case, turn ON pin 2 on the DIP switch on the
front of the CPU Unit so that data stored in the Memory Cassette is trans-
ferred to the CPU Unit automatically at startup.
Note If the internal battery expires, the data in the CPU Unit (user program, set-
tings, etc.) will be lost when the power is turned OFF.
Consider the following precautions when operating with no internal battery or
with an expired battery.
• When the internal battery expires, data will be affected in the following
way.
