FCC Class B
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interfer-
ence when the equipment is operated in a residential environment. This
equipment generates, uses and can radiate radio frequency energy. If not
installed and used in accordance with this user's manual, it may cause
harmful interference to radio communications. Note that even when this
equipment is installed and used in accordance with this user's manual,
there is still no guarantee that interference will not occur. If this equip-
ment is believed to be causing harmful interference to radio or television
reception, this can be determined by turning the equipment on and off. If
interference is occurring, the user is encouraged to try to correct the inter-
ference by one or more of the following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and the receiver
• Connect the equipment to a power outlet on a circuit different from that
to which the receiver is connected
• Consult the dealer or an experienced radio/TV technician for help
Warning! Any changes or modifications made to the
equipment which are not expressly approved by
the relevant standards authority could void your
authority to operate the equipment.

IPPC-9120G/9150G Users Manual 2
Chapter 1 General Information
1.1 Introduction
IPPC-9120G and IPPC-9150G series of industrial panel PCs are espe-
cially designed to fit in space-limited environments where expansion is
restricted. Its solid structure enables the systems to operate under harsh
industrial conditions.
Sturdy structure
The whole system is protected by a firm solid structure. The front panel is
made of sturdy aluminum and has strengthened glass. It is shock resistant,
and complies with NEMA4/IP65. The stainless steel case (SUS304) on
the rear side is rugged and corrosion resistant, and enables the system to
operate reliably in even the harshest of environments.
Easy maintenance
A back door with lock is located right above the motherboard. Thus users
can easily maintain the CPU, HDD, SDRAM and CD-ROM drive. Jump-
ers can be easily set without removing a single screw. The lock protects
the system from intruders.
Economical
The PCM-9672 motherboard has Socket 370 architecture. It supports
Pentium III up to 1.26 GHz and Celeron up to 1.3 GHz. Socket 370 is an
economical yet powerful system. Its reliability enables the system to
operate faultlessly in industrial environments.
Friendly HMI
The IPPC-9120G and IPPC-9150G Series are equipped with a 12.1"/15"
LCD, which provides high resolution display quality (IPPC-9120G: 800 x
600; IPPC-9150G:1024 x 768). The result is vivid, bright, and sharp qual-
ity images. The IPPC-9120G and IPPC-9150G Series are perfectly suited
for Windows OSs. The touschscreen version enables simple operation,
making the IPPC-9120G and IPPC-9150G Series premier industrial digi-
tal controller interfaces.
