Theory of Operation

Theory of Operation

This section provides a brief overview of the board level theory of operation for
the portable mainframe. Refer to page 6–2 for a functional block diagram.

Portable Mainframe

The portable mainframe contains the following major components:

Power Supply

Backplane

Controller Board

Front Panel

Interface Board

Front Panel Controller

Board

The power supply provides all voltages and currents to the portable mainframe.
The power supply connects to the backplane at P400 and P401.

The backplane connects the power supply secondary to the remainder of the
system, including the fans, distributes the precision 10-MHz (CLK10) system
clock, and supports all communication between the instrument modules.

The controller board provides the portable mainframe with a high-performance
PC-based controller architecture, and interfaces to the backplane bus and front
panel. The controller board mounts vertically on the left side of the instrument
and connects to the back of the backplane. The controller board provides I/O to
the rear panel and is the source of the 10-MHz (CLK10) system clock.

The front panel interface board interconnects the controller board, the flat-panel
display, the floppy disk drive, the front-panel keypad and glidepoint, dual USB
ports, and the external mouse and keyboard ports. Dual 50-pin cables connect the
front panel interface board to the controller board. The interface board also
supplies the PC speaker.

The front panel controller board combines signals from the front-panel hex
keypad, the front-panel QWERTY keypad, and an external keyboard to generate
or receive standard keyboard scan-codes from the controller board.

Mechanical Chassis

TLA 714 Color Portable Mainframe Service Manual

Preventing ESD

This chapter provides procedures for inspecting and cleaning the portable
mainframe, removing and replacing internal chassis components, and isolating
problems to the board or replacement part level.

To repair, you must exchange or replace the failed part; this manual does not
provide component-level procedures for isolating components on the failed part.

The information in this chapter is designed for use by qualified service person­nel. Read the Safety Summary at the front of this manual before attempting any
procedures in this chapter. Refer to the Operating Information chapter for
information on the location of controls, indicators, and connectors used with the
chassis.

When performing any service which requires internal access to the portable
mainframe, adhere to the following precautions to avoid damaging internal
circuit boards and their components due to electrostatic discharge (ESD).

CAUTION. Many components within the chassis are susceptible to static­discharge damage. Service the chassis only in a static-free environment.

Observe standard handling precautions for static-sensitive devices while
servicing the chassis.

Always wear a grounded wrist strap, or equivalent, while servicing the chassis.

1. Minimize handling of static-sensitive circuit boards.

2. Transport and store static-sensitive circuit boards in their static protected

containers or on a metal rail. Label any package that contains static-sensitive
boards.

3. Discharge the static voltage from your body by wearing a grounded antistatic

wrist strap while handling these circuit boards. Do service of static-sensitive
circuit boards only at a static-free work station.

4. Nothing capable of generating or holding a static charge should be allowed

on the work station surface.

Interior Cleaning

Exterior Cleaning

Cleaning procedures consist of exterior and interior cleaning of the chassis.
Clean the chassis as needed, based on the operating environment. Refer to the
appropriate module service manuals for information on cleaning individual
TLA 700 Series modules.

Use a dry, low-velocity stream of air to clean the interior of the chassis. Use a
soft-bristle, non-static-producing brush for cleaning around components. If you
must use a liquid for minor interior cleaning, use a 75% isopropyl alcohol
solution and rinse with deionized water.

Clean the exterior surfaces of the chassis with a dry lint-free cloth or a soft­bristle brush. If any dirt remains, use a cloth or swab dipped in a 75% isopropyl
alcohol solution. Use a swab to clean narrow spaces around controls and
connectors. Do not use abrasive compounds on any part of the chassis that may
damage the chassis.

Clean the On/Standby switch using a dampened cleaning towel. Do not spray or
wet the switch directly.

4–2

TLA 714 Color Portable Mainframe Service Manual

Maintenance

CAUTION. Avoid getting moisture inside the chassis during exterior cleaning; use
just enough moisture to dampen the cloth or swab.

Do not wash the front-panel On/Standby switch. Cover the switch while washing
the chassis.

Use only deionized or distilled water when cleaning. Use a 75% isopropyl
alcohol solution as a cleanser and rinse with deionized or distilled water.

Do not use chemical cleaning agents; they may damage the chassis. Avoid
chemicals that contain benzene, toluene, xylene, acetone, or similar solvents.

Flat Panel Display

Cleaning

The portable mainframe display is a soft plastic display and must be treated with
care during cleaning.

CAUTION. Improper cleaning agents or methods can damage the flat panel
display.

Avoid using abrasive cleaners or commercial glass cleaners to clean the display
surface.

Avoid spraying liquids directly on the display surface.
Avoid scrubbing the display with excessive force.

Clean the flat panel display surface by gently rubbing the display with a
clean-room wipe (such as Wypall Medium Duty Wipes, #05701, available from
Kimberly-Clark Corporation).

If the display is very dirty, moisten the wipe with distilled water or a 75%
isopropyl alcohol solution and gently rub the display surface. Avoid using excess
force or you may damage the plastic display surface.
