Chapter 1 General Information 1

Introduction

The SBC-410 is an all-in-one CPU card that supports L2 cache
sizes from 128 KB to 512 KB (32 KB x 8, 64 KB x 8, or 128 KB x

8). This CPU card uses the M1489/M1487 chipsets, which accept
Intel, AMD, Cyrix, or other compatible 486-based CPUs. The SBC­410 is fully PC/AT compatible, so your software will run without
modifications.

On-board features include two high-speed serial ports (RS-232 and
RS-232/422/485) with 16C550 UAR T s, one bi-directional parallel port,
and a floppy drive controller. If program execution is halted by a
program bug or EMI, the board's 15-stage watchdog timer can
automatically reset the CPU or generate an interrupt. This ensures
reliability in unmanned or stand-alone systems.

The SBC-410 is built with two high speed local bus Enhanced IDE
controllers. This controller supports (through AT A PIO) mode 3 and
mode 4 hard disks, which enable data transfer rates of over 11 MB/
second. It connects up to four IDE devices, including large hard disks,
CD-ROM drives, tape backup drives, etc. The built-in enhanced IDE
controller provides a 4-layer 32-bit posted write-buffer and a 4-layer 32­bit read-prefetch-buffer to boost IDE performance.

The SBC-410 supports 5V EDO DRAM. It also provides two 72-pin
SIMM (Single In-line Memory Module) sockets for on-board DRAM.
This gives you the flexibility to configure your system memory from 1
~ 64 MB using the most economical combination of SIMMs.

The SBC-410 also features power management to minimize power
consumption. It uses CMOS components and complies with the
"Green Function" standard.

If you need any additional functions, you can add industry-standard
PC/104 expansion modules. W e provide numerous PC/104 modules to
meet your system requirements.

Setting jumpers

You configure your card to match the needs of your application by
setting jumpers. A jumper is the simplest kind of electric switch.
It consists of two metal pins and a small metal clip (often
protected by a plastic cover) that slides over the pins to connect
them. To "close" a jumper you connect the pins with the clip. To
"open" a jumper you remove the clip. Sometimes a jumper will
have three pins, labeled 1, 2 and 3. In this case you would connect
either pins 1 and 2 or 2 and 3.

Open Closed Closed 2-3

The jumper settings are schematically depicted in this manual as
follows:

2

A pair of needle-nose pliers may be helpful when working with
jumpers.

If you have any doubts about the best hardware configuration for
your application, contact your local distributor or sales represen­tative before you make any changes.

Generally, you simply need a standard cable to make most
connections.

12 SBC-410 User's Manual

Safety Precantions

Warning! Always completely disconnect the power cord

from your chassis whenever you are working on
it. Do not make connections while the power is
on, sensitive electronic components can be
damaged by the sudden rush of power. Only
experienced electronics personnel should open
the PC chassis.

Caution! Always ground yourself to remove any static

charge before touching the CPU card. Modern
electronic devices are very sensitive to static
electric charges. Use a grounding wrist strap at
all times. Place all electronic components on a
static-dissipative surface or in a static-shielded
bag when they are not in the chassis.

Installing the CPU

The SBC-410 CPU card supports most 486 CPUs. The system's
performance depends on the CPU you choose. You can install or
upgrade the CPU in the board's PGA socket by following the
procedures outlined below. If your system has an existing CPU,
you need to remove it before installing the new CPU.

Removing a CPU

1. Disconnect power from the chassis, and unplug all connec­tions to the CPU card. Then, remove the CPU card from the
chassis by following the instructions in the user's manual for
your chassis.

2. Lift the CPU out of the PGA socket. The old chip may be
difficult to remove. You may find spray chip lubricant,
designed for pin-grid-array (PGA) devices, and a chip puller
helpful. These are available at electronics hobbyists' supply
stores.

Chapter 2 Installation 13

Installing a CPU

To install the CPU, follow the instructions that came with it. If no
documentation is provided, the general procedure for installing a
CPU are outlined below:

1. Lubricate the pins on the CPU with lubricant for PGA devices.
This makes the CPU slide in much easier and greatly reduces
the chance of damaging the pins and other components.

2. Carefully align the CPU so that it is parallel to the socket.
Make sure that the notch on the corner of the CPU matches
the notch on the inside of the socket.

3. Gently push the CPU into the socket. There will probably be a
small gap between the CPU and the socket even when it is
fully seated. DO NOT USE EXCESSIVE FORCE!

When you install a new CPU, you may have to adjust other
settings on the board, such as CPU type, CPU clock and PCI
speed, to accommodate it. Make sure that the settings are correct
for your CPU. Improper settings may damage the CPU.

Installing DRAM (SIMMs)

The SBC-410 CPU card provides two 72-pin SIMM (Single In­line Memory Module) sockets and supports between 1 MB to 64
MB of RAM.

When installing SIMMs, make sure that Bank 1 is filled first.

Installing SIMMs

Note that the modules can only fit into a socket one way.

1. Insert the memory module into the socket at a moderate angle.

2. Push the module toward the vertical posts at both ends of the
socket until the module is upright, and the retaining clips at
both ends of the module click into place. When positioned
correctly, the pins on top of the vertical posts should corre­spond to the circular holes on the ends of the module.

3. Repeat steps 1 and 2 for each module you install.

Removing SIMMs

If you need to remove a SIMM, follow the procedures below:

1. Supporting the SIMM with a finger, use a pen or a similarly
shaped object and press one retaining clip straight down.

2. Repeat for the other side. When released, the retaining clips
will push the SIMM up and out of its upright position.

3. Carefully pull the SIMM out of the socket with your fingers.

4. Repeat the above steps for each module you remove.

Chapter 2 Installation 17

Selecting cache memory size

The SBC-410 features a 2nd level memory cache that supports
128, 256, or 512 KB of cache memory. Higher cache memory
can improve your system's performance.

The cache uses SRAM chips in three sizes: 32 KB, 64 KB and
128 KB. The on-board cache memory banks consists of four
SRAM chip sockets, each of which accepts one "T ag" chip. All
SRAM chips must have a speed of 20 ns or faster. The table below
shows the possible cache configurations:

Cache Configuration

Cache size Tag RAM Data RAM

128 KB one 32 K x 8 four 32 KB x 8 SRAMs
256 KB one 32 K x 8 four 64 KB x 8 SRAMs

IDE hard drive connections (Primary/

Secondary IDE)

You can attach up to four Enhanced Integrated Device Electronics
hard disk drives to the SBC-410's internal controllers. The card
comes with a 40-pin and a 44-pin flat-cable piggyback cables. The
40-pin flat-cable has three identical 40-pin connectors.

Connecting the hard drive

Wire number 1 on the cable is red or blue, and the other wires are
gray.

1. Connect one end of the cable to Primary IDE or Secondary
IDE on the CPU card. Make sure that the red (or blue) wire
corresponds to pin 1 on the connector, which is labeled on the
board (on the right side).

2. Plug the other end of the cable to the Enhanced IDE hard
drive, with pin 1 on the cable corresponding to pin 1 on the
hard drive. (See your hard drive's documentation for the
location of the connector.)

Unlike floppy drives, you can make the connections with any of
the connectors on the cable. If you install two drives, you will
need to set one as the master and one as the slave. You do this
using jumpers on the drives. If you install just one drive, set it as
the master.

You can attach up to two floppy disks to the SBC-410's on-board
controller. You can use any combination of 5.25" (360 KB and 1.2
MB) and/or 3.5" (720 KB, 1.44 MB, and 2.88 MB) drives.

The SBC-410 CPU card comes with a 34-pin daisy-chain drive
connector cable. On one end of the cable is a 34-pin flat-cable
connector. There are two sets of floppy disk drive connectors,
one in the middle, and one on the other end. Each set consists of a
34-pin flat-cable connector (usually used for 3.5" drives) and a
printed-circuit board connector (usually used for 5.25" drives).

Connecting the floppy drive

1. Plug the 34-pin flat-cable connector into FDC CON on the
CPU card.

2. Attach the appropriate connector on the other end of the cable
to the floppy drive(s). You can use only one connector in the
set. The set on the end (after the twist in the cable) connects
to the A: floppy. The set in the middle connects to the B:
floppy.

Parallel port (PRINTER)

Normally, the parallel port is used to connect the card to a
printer. The SBC-410 includes an on-board parallel port, which
is accessed through a 26-pin flat-cable connector. The CPU
card comes with an adapter cable, which lets you use a tradition­al DB-25 connector. The cable has a 26-pin connector on one
end and a DB-25 connector on the other, mounted on a retaining
bracket.

Installing the retaining bracket

The retaining bracket installs at an empty slot in your system's
chassis. It provides an external port that allows your parallel
peripheral to access to the card's parallel port connector.

1. Find an empty slot in your chassis.

2. Unscrew the plate that covers the end of the slot.

3. Screw in the bracket in place of the plate.

4. Next, attach the flat-cable connector to PRINTER on the
CPU card. Wire 1 of the cable is red or blue, and the other
wires are gray. Make sure that Wire 1 connects to Pin 1 of
the PRINTER connector. Pin 1 is on the right side of
PRINTER.

Serial ports

The SBC-410 offers two serial ports: one RS-232 and one RS­232/422/485. Using the BIOS Peripheral Setup program, you can
select the address for each port or disable it.

The card mounting bracket has two serial port connectors. The
DB-9 connector on the top of the bracket is COMA, the RS-232
serial port. The DB-9 connector on the bottom of the bracket is
COMB, the RS-232/422/485 serial port.

RS-232/422/485 select for COMB

(JP12, JP13, JP14, JP15, JP16)

RS-232 serial ports are widely used for external input/output
devices. The RS-422 and RS-485, however, are popular for
industrial and laboratory applications because they offer high
noise resistance and long range communication (up to 4000 ft,
1200 m). The RS-422 is commnly used for two-way communica­tion between two devices, where as RS-485 is used for communi­cation between a single master and a network of slave modules.

COMA is the RS-232 serial port, and COMB can function as an
RS-232, RS-422, or RS-485, depending on the jumper settings
from JP12, JP13, JP14, JP15 and JP16. To select the desired
serial port type for COMB, adjust JP12, JP13, JP14, JP15, and
JP16:

RS-422 signal wiring

RS-422 is used for long-distance point-to-point connections. RS­422 originally used four wires for one-way communication (with
devices such as display terminals or printer) but was later adopted
by the industry for simultaneous two-way communication by
doubling the number of wires.

Each pin on the first device connects to a corresponding device
on the second. Flow control lines manage the communication.
The following table shows pin connections.

RS-485 signal wiring

In a typical RS-485 application, the host device requests data
from a slave module then listens for the response. The host
transmits and receives data on the same pair of wires. Software
handles the flow control; no other wires are needed.

Pin assignments appear in the following table. Pins 1 and 4 share
the Data- wire. Pins 2 and 3 share the Data+ wire.

Watchdog timer programming

The watchdog timer must be programmed to write to I/O port
address 443 at an interval shorter than the timer's preset interval.
The timer's interval has a tolerance of ±5%, so you should
program an instruction that will refresh the timer before a time­out occurs. The following steps illustrate how you might
program the watchdog timer.

Chapter 2 Installation 29

1. Write to I/O port 443 (Hex) and designate a time-out interval.
This will enable the watchdog and set up its time-out interval.

2. Write to I/O port 080 (Hex) and any random value. This will in
turn disable the watchdog timer.

The watchdog timer-out interval can be set at 15 levels between 2
and 32 seconds. The following table shows the Hex values for the
appropriate time-out intervals:

ECP

The normal parallel port mode is used. This is the
default setting.

The parallel port can be used with devices that
adhere to the Enhanced Parallel Port (EPP) specifi­cation. EPP uses the exiting parallel port signals to
provide asymmetric bidirectional data transfer
driven by the host device.

The parallel port can be used with devices that
adhere to the Extended Capabilities Port (ECP)
specification. ECP uses the DMA protocol to
achieve transfer rates of approximately 2.5 Mbs.
ECP provides symmetric bidirectional communla­tions.

Installing PC/104

Modules

This appendix gives instructions for
installing PC/104 module.

Appendix B Installing PC/104 Modules 67

Installing PC/104 modules

The SBC-410's PC/104 connectors give you the flexibility to
attach PC/104 expansion modules. These modules perform the
functions of traditional plug-in expansion cards, but save space
and valuable slots. Modules include:

• PCM-3600 FAX/Modem Module

• PCM-3420 Fast SCSI-2 Module

• PCM-3200 Sound Module

• PCM-3810 Solid State Disk Module

• PCM-3820 High Density Flash Disk Module

• PCM-3115 PCMCIA Module (two slots)

• PCM-3610 Isolated RS-232 and RS-422/485 Module

• PCM-3660 Ethernet Module

• PCM-3718 30 KHz A/D Module

• PCM-3724 48-channel DIO Module

• PCM-3910 Breadboard Module
To install these modules on the SBC-400 is a quick and simple

operation. The following steps show how to mount the PC/104
modules:

Step 1 Remove the SBC-410 from your system paying

particular attention to the safety instructions already
mentioned above.

Step 2 Make any jumper or link changes required to the

CPU card now . Once the PC/104 module is mounted
you may have difficulty in accessing these.

Step 3 Normal PC/104 modules have "male" connectors

and mount directly onto the main card. However,
for reasons that ensure better bus matching, the
connectors on the SBC-410 and the PC/104 module
are both "female". For this reason you need to plug­in a "male-male" adapter connecter (included with
the SBC-410). Please refer to the following PC/104
module mounting diagram on the following page.
After this is in place you then have the correct
mounting connector to accept your PC/104 module.

68 SBC-410 User's Manual

Step 4 Mount the PC/104 module onto the CPU card.

Do this by pressing the module firmly but carefully
onto the mounting connectors.

Step 5 Secure the PC/104 module onto the CPU card using

the four mounting spacers and srews.
