A Message to the Customer
AAEON Customer Services
Each and every AAEON product is built to the most exacting
specifications to ensure reliable performance in the harsh and
demanding conditions typical of industrial environments. Whether
your new AAEON equipment is destined for the laboratory or the
factory floor, you can be assured that your product will provide the
reliability and ease of operation for which the name AAEON has
come to be known.
Your satisfaction is our primary concern. Here is a guide to
AAEON’s customer services. To ensure you get the full benefit of
our services, please follow the instructions below carefully.
Technical Support
We want you to get the maximum performance from your products.
So if you run into technical difficulties, we are here to help. For the
most frequently asked questions, you can easily find answers in
your product documentation. These answers are normally a lot
more detailed than the ones we can give over the phone.
So please consult this manual first. If you still cannot find the
answer, gather all the information or questions that apply to your
problem, and with the product close at hand, call your dealer. Our
dealers are well trained and ready to give you the support you need
to get the most from your AAEON products. In fact, most problems
reported are minor and are able to be easily solved over the phone.
In addition, free technical support is available from AAEON
engineers every business day. We are always ready to give advice
on application requirements or specific information on the installa-
tion and operation of any of our products.

Product Warranty
AAEON warrants to you, the original purchaser, that each of its
products will be free from defects in materials and workmanship for
one year from the date of purchase.
This warranty does not apply to any products which have been
repaired or altered by persons other than repair personnel autho-
rized by AAEON, or which have been subject to misuse, abuse,
accident or improper installation. AAEON assumes no liability
under the terms of this warranty as a consequence of such events.
Because of AAEON’s high quality-control standards and rigorous
testing, most of our customers never need to use our repair service.
If an AAEON product is defective, it will be repaired or replaced at
no charge during the warranty period. For out-of-warranty repairs,
you will be billed according to the cost of replacement materials,
service time, and freight. Please consult your dealer for more
details.
If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. (For
example, CPU type and speed, AAEON products used, other
hardware and software used, etc.) Note anything abnormal and
list any on-screen messages you get when the problem occurs.
2. Call your dealer and describe the problem. Please have your
manual, product, and any helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA
(return material authorization) number from your dealer. This
allows us to process your return more quickly.
4. Carefully pack the defective product, a fully-completed Repair
and Replacement Order Card and a photocopy proof of pur-
chase date (such as your sales receipt) in a shippable container.
A product returned without proof of the purchase date is not
eligible for warranty service.
5. Write the RMA number visibly on the outside of the package
and ship it prepaid to your dealer.

Packing list

2PCM-7890 User Manual
Introduction
ThePCM-7890 isan all-in-one multi-mediaPentium II processor
based single board computer (SBC) with a 32-bit PCI audio
controller, a PCI Flat Panel controller, a PCI 100Base-Tx
Ethernet interface, and one PCI expansion slot. When using an
Intel Pentium II processor, the PCM-7890 achieves outstanding
performance that surpasses any other SBC in its class. In addition,
the onboard SSD interface supports M-systems DiskOnChip
2000 series, memory capacity from 2 MB to 144 MB. This
compact (only 5.75"“ x 8") unit offers all the functions of a single
board industrial computer, but still fits in the space of a CD-ROM
drive.
On-board features include four serial ports (three RS-232, one RS-
232/422/485),onemulti-modeparallel(ECP/EPP/SPP) port, connec-
tor for two USB (Universal Serial Bus) ports, a floppy drive
controller, and a keyboard/PS/2 mouse interface. The built-in high
speed PCI IDE controller supports Ultra DMA/33 mode. Up to two
IDE devices can be connected, including large hard disks, CD-
ROM drives, and tape backup drives, etc.
ThePCM-7890 alsofeatures power management to minimize power
consumption. It complies with the ACPI standard and supports
three types of power saving features: Doze mode, Standby mode,
and Suspend mode. In addition, the board's watchdog timer can
automatically reset the system or generate an interrupt in case the
system stops due to a program bug or EMI.
Highly integrated multi-media SBC
ThePCM-7890 isa highly integrated multi-media SBC that com-
bines audio, video, and network functions on a CD-ROM drive size
single computer board. It provides 32-bit half-duplex, 16-bit full-
duplex, integrated 3D audio and up to 1024 x 768 resolution @ 64K
colors with on-chip 2MB SDRAM display memory. Major onboard
devices adopt PCI technology to achieve outstanding computing
performance when used with Intel Pentium II level processors,
making the PCM-7890 one of the world's smallest and most
powerfulall-in-one multimedia board.
