1-2 System Configuration
The CQM1 is a compact, high-speed PC composed of a Power Supply Unit, a
CPU Unit, and I/O Units. All of these Units connect at the sides to form a single
PC, which is normally mounted to a DIN track.
All CQM1 CPU Units, except for the CQM1-CPU11-E, are equipped with an
RS-232C port that can be connected directly to a host computer, another CQM1,
or other serial devices.
The following diagram shows the system configurations possible with the
CQM1. Refer to Section 2 Hardware Considerations for more details on system
