1. IMPORTANT SAFE HANDLING INFORMATION

WARNING!

ESD-Sensitive Electronic Equipment

Observe ESD-safe handling procedures when working with this product.

Always use this product in a properly grounded work area and wear appropriate

ESD-preventive clothing and/or accessories.

Always store this product in ESD-protective packaging when not in use.

Safe Handling Precautions

The Helios board contains a high number of I/O connectors with connection to sensitive electronic components.

This creates many opportunities for accidental damage during handling, installation and connection to other

equipment. The list here describes common causes of failure found on boards returned to Diamond Systems for

repair. This information is provided as a source of advice to help you prevent damaging your Diamond (or any

vendor’s) embedded computer boards.

ESD damage –This type of damage is usually almost impossible to detect, because there is no visual sign of

failure or damage. The symptom is that the board eventually simply stops working, because some component

becomes defective. Usually the failure can be identified and the chip can be replaced.

To prevent ESD damage, always follow proper ESD-prevention practices when handling computer boards.

Damage during handling or storage –On some boards we have noticed physical damage from mishandling. A

common observation is that a screwdriver slipped while installing the board, causing a gouge in the PCB surface

and cutting signal traces or damaging components.

Another common observation is damaged board corners, indicating the board was dropped. This may or may not

cause damage to the circuitry, depending on what is near the corner. Most of our boards are designed with at

least 25 mils clearance between the board edge and any component pad, and ground / power planes are at least

20 mils from the edge to avoid possible shorting from this type of damage. However these design rules are not

sufficient to prevent damage in all situations.

A third cause of failure is when a metal screwdriver tip slips, or a screw drops onto the board while it is powered

on, causing a short between a power pin and a signal pin on a component. This can cause overvoltage / power

supply problems described below. To avoid this type of failure, only perform assembly operations when the

system is powered off.

Sometimes boards are stored in racks with slots that grip the edge of the board. This is a common practice for

board manufacturers. However our boards are generally very dense, and if the board has components very close

to the board edge, they can be damaged or even knocked off the board when the board tilts back in the rack.

Diamond recommends that all our boards be stored only in individual ESD-safe packaging. If multiple boards are

stored together, they should be contained in bins with dividers between boards. Do not pile boards on top of each

other or cram too many boards into a small location. This can cause damage to connector pins or fragile

components.

Power supply wired backwards –Our power supplies and boards are not designed to withstand a reverse

power supply connection. This will destroy each IC that is connected to the power supply (i.e. almost all ICs). In

this case the board will most likely will be unrepairable and must be replaced. A chip destroyed by reverse power

or by excessive power will often have a visible hole on the top or show some deformation on the top surface due

to vaporization inside the package. Check twice before applying power!

Board not installed properly in PC/104 stack –A common error is to install a PC/104 board accidentally shifted

by 1 row or 1 column. If the board is installed incorrectly, it is possible for power and ground signals on the bus to

make contact with the wrong pins on the board, which can damage the board. For example, this can damage

components attached to the data bus, because it puts the 12V power supply lines directly on data bus lines.

Helios User Manual Rev B9 www.diamondsystems.com Page 5

Overvoltage on analog input –If a voltage applied to an analog input exceeds the design specification of the

board, the input multiplexor and/or parts behind it can be damaged. Most of our boards will withstand an

erroneous connection of up to 35V on the analog inputs, even when the board is powered off, but not all boards,

and not in all conditions.

Overvoltage on analog output –If an analog output is accidentally connected to another output signal or a

power supply voltage, the output can be damaged. On most of our boards, a short circuit to ground on an analog

output will not cause trouble.

Overvoltage on digital I/O line –If a digital I/O signal is connected to a voltage above the maximum specified

voltage, the digital circuitry can be damaged. On most of our boards the acceptable range of voltages connected

to digital I/O signals is 0-5V, and they can withstand about 0.5V beyond that (-0.5 to 5.5V) before being damaged.

However logic signals at 12V and even 24V are common, and if one of these is connected to a 5V logic chip, the

chip will be damaged, and the damage could even extend past that chip to others in the circuit.

Bent connector pins –This type of problem is often only a cosmetic issue and is easily fixed by bending the pins

back to their proper shape one at a time with needle-nose pliers. The most common cause of bent connector pins

is when a PC/104 board is pulled off the stack by rocking it back and forth left to right, from one end of the

connector to the other. As the board is rocked back and forth it pulls out suddenly, and the pins at the end get

bent significantly. The same situation can occur when pulling a ribbon cable off of a pin header. If the pins are

bent too severely, bending them back can cause them to weaken unacceptably or even break, and the connector

must be replaced.

2. INTRODUCTION

Helios is an embedded single board computer in the PC/104 small form factor based on the DMP Vortex86DX

family of all-in-one 486 processors. Helios integrates a complete embedded PC plus a full analog and digital data

acquisition circuit into a single board. It is available in several models with different features:

Programmable gate and count enable

Internal (10MHz) or external clock source

Bus Interfaces

The Vortex86DX processor generates both PCI and ISA buses for I/O expansion. The 33MHz 32-bit PCI bus is

used internally for the Ethernet circuit and is not brought out to a PCI-104 expansion connector.

The 8MHz 16-bit ISA bus is brought out to a standard PC/104 stackthrough connector, enabling 16-bit and 8-bit

modules to be installed either above or below the board. Interrupt and DMA performance is supported on the ISA

bus. Up to 4 I/O boards can be installed on the ISA bus on Helios, depending on the loading characteristics of the

add-on modules.

Battery Backup

Helios contains a backup battery for the real-time clock and BIOS settings. The battery is directly soldered to the

board and provides a minimum 7 year backup lifetime at 25°C. For longer lifetime an external battery of 3.3V +/-

10% may be attached to the board.

Watchdog Timer

Helios contains a watchdog timer (WDT) circuit with a software-programmable timer. The time delay can be

programmed, and the timer can be retriggered with an I/O write command. When the timer times out, it will trigger

an IRQ or system reset depending on the user configuration.

Power Supply

Helios requires only +5V +/-5% for operation. The input power connector provides connections for optional

provision of +/-12V and -5V for pass through to the ISA bus if needed for attached I/O modules.
