Introduction
The GCI Handheld Tester is an efficient tool for quickly testing, trouble-shooting, and resolving E84
problems. It is a self-contained, battery operated tool integrating the industry-leading automated load
and unload routines provided in the GCI E84 Emulator. It incorporates a number of industry firsts to
quickly locate answers to E84 problems:
•Voltage and current measurement of each E84 signal
•Automated optical transceiver test
•Real-time display of E84 communications using the GCI E84 DLD and
GCI RJ-11 Optical Transceiver
Starting with Revision 3.0, the HHT provides a Secure Digital Flash card interface. Test results from all HHT
provided tests can be stored onto an inserted SD Card. DLD Log files can also be stored on an SD Card.
The new SD Card interface provides a simple method of transferring test results to a PC for additional
analysis. Test results are saved in binary format compatible with the GCI E84 Analysis Application.
Additional test results and information are stored in a formatted ASCII text file.

Figure 2 - Soft Keys and Icons
Navigating The E84 HHT Menus
Text and graphics menus provide the user interface to
perform functions provided by the E84 HHT. Navigate
the menus using the soft keys, arrow keys, and Enter
key.
Using The Soft Keys
The E84 HHT keypad provides eight soft keys in a two
row by four column configuration. Each soft key has an
associated ICON on the lower portion of the LCD. Use
the soft keys to navigate the menus and select options.
For example, from the Test Menu, press the upper right
soft key to advance to the Manual Mode Control
menu. Note that there is not a function for the lower
right soft key as indicated by a blank ICON.
In menus that display only the bottom row of soft key
ICONs, use the bottom row of soft keys to make
selections.

Paperless Storage System (PSS)
Test results data can be saved in the HHT’s Paperless Storage System (PSS). The PSS provides a
convenient method of documenting E84 troubleshooting activities. Data stored in the PSS can be
transferred to a computer for detailed analysis, reporting or archival purposes.
The HHT displays a Save soft key in each test screen that supports the PSS. The format of data saved
depends on the HHT test in progress. Specific data formats are described in individual test sections
below.
SD Card Interface
Starting with Version 3.00, the HHT provides an SD Card interface for the PSS. Previous versions relied on
internal non-volatile flash memory for data storage. This resulted in time-consuming uploads of test
results when additional analysis was needed on a PC.
With the new SD Card interface, transferring test results to a PC becomes trivial. Simply remove the SD
Card from the HHT, and insert it into an SD Card reader (supplied) connected to a PC. All HHT test result
are then available directly as files on the SD Card.
The HHT provides an SD Card slot in the front panel. SD Cards can be inserted only in one orientation.
Slide the SD Card into the slot with the SD Card label facing up. Press the card fully into the slot until you
hear a small ‘click’. The SD Card slot is spring loaded. To remove the card, press in gently, which will
cause the spring to release, allowing the card to be removed.

SD Card Format
All HHT’s are shipped with a pre-formatted SD Card. The HHT is compatible with any SD Card that has
been formatted with the FAT16 file system. FAT16 is fully supported by all versions of Microsoft Windows®.
Before using a new SD Card, format it for FAT16 using Windows Explorer®. Warning: formatting the SD
Card will erase the card, resulting in the loss of any data stored on it.
File Organization
HHT Test results files are organized by Tool ID. Each E84 interface in the FAB is associated with an EFEM
(Equipment Front End Module) on a specific Tool. When testing a specific EFEM, it is convenient to
organize all stored test results together.
Tool ID
The HHT stores all test results in a folder on the SD Card called HHT_DATA. Within the HHT_DATA folder, a
series of Tool ID text files define the Tools being tested. The Tool ID files can be created using a text
editor (Notepad) on the PC, or on the HHT using the Stored Test Data option. See below for the file
format to use when creating Tool ID files on the PC. A description on creating new Tool ID’s on the HHT
can be found below.
The Tool ID file contains the Tool’s ID (max. 8-character name), it’s Location (max 20-characters), and a
description of the Tool (max. 100-characters). The ID file also contains a breakdown of the types of tests
stored by the HHT for that Tool.
Using The Handheld Tester

PAGE 6
Figure 3 - Example SD Card File System
When the HHT stores data to a specific Tool, a sub-folder is created within the HHT_DATA folder. The Tool
ID is used as the name for this new folder. All test results stored for this Tool is placed within this sub-
folder. This folder is created automatically by the HHT. There is no need to create the folder manually.
Figure 3 shows an example of the SD Card file organization.
The Combo Drive E: is the Windows Explorer tag for the SD
Card. The root folder of the SD Card has a single folder in it
called HHT_DATA. Inside this folder, a series of sub-folders
and text files are displayed. The text files (TOOL001A.TXT,
TOOL001B.TXT, TOOL001C.TXT and TOOL002.TXT) are Tool ID
files. Each Tool ID file is associated with a sub-folder (of the
same name, minus the .TXT extension). All test results for a
given tool are stored within the associated sub-folder.
Test Results File Name
The HHT automatically names stored test results files based on the test type. The HHT keeps index
counters for each type of test. When results from a specific test type are stored, the HHT creates a
filename in the format XXNNNNNN.DAT where XX is a two character test type code, and NNNNNN is a six
digit index number. The first file saved for a specific test type is given index number 1. The index
number is incremented for each subsequent results file saved.

Figure 4 - Stored Test Results Files
Figure 4 shows test results stored for Tool ID TOOL001A. The
folder for TOOL001A contains two different test results, one
from a Cycle Test, the other from a Emulator Test Suite test.
The filename for the Cycle test is CY000001.DAT, which
indicates it is the first CYCLE test saved for TOOL001A. The
.DAT extension indicates it is a binary file that is formatted for
use with the GCI E84 Analysis Application. A second file of
the same name, with a .TXT extension, contains additional test details in a formatted ASCII report. This
file can be viewed with any text editor.
The filename for the Emulator Test Suite is TS000001.DAT, which indicates it is the first Test Suite test saved
for TOOL001A.
If another Cycle or Test Suite test was saved, the index number would be incremented. The file time-
stamp indicates when the test results were stored, and can be used as a method of determining the
desired file when viewing on the PC.
Tool ID File Format
Tool ID files can be created using a text editor (Notepad) on the PC. Simply create a file with the
following format, and save it to the HHT_DATA folder on a SD Card. If the SD Card has not been used
previously with an HHT, you must first create the HHT_DATA folder.
Figure 5 shows the Tool ID File Format. The file should contain 9 lines of text. Each line contains a

specific piece of information about the Tool, and is terminated with a carriage return.
Line 1: Tool Name - maximum of 8 characters. This will also be the
name of the file, with a .TXT extension. The Tool Name is
used as the filename, and the name of the folder where
test results will be stored, therefor the name cannot contain
the following characters: \/:*?”<>|.
Line 2: Tool Location - maximum 20 characters. This is a free
format text string that can be used to define the location of
the Tool in the FAB (i.e. bay number, EFEM number).
Line 3: Tool Details - maximum 100 characters. This is a free
format text string that can be used to describe the Tool.
This can include Tool manufacturer, tool type, etc.

Power Supply Voltage Test
Use the power supply voltage test to verify that the load port
supplies the required power for a transceiver. The Power Supply
Voltage Test is only available in the direct connect
configuration.
The E84 Specification states that the passive equipment (load
port) must supply voltage on Pin 23 of the female DB-25
connector. It further specifies that the passive equipment
should leave pin 22 unconnected. The active equipment
supplies voltage on pin 22. The E84 Specification further states that the voltage level must remain with
+18 VDC and +30 VDC under both no-load and full-load conditions.
The HHT measures the voltage level on both pins, under no-load and full-load conditions. The voltage
measurements are displayed on the screen. To be compliant, all four measurements must remain

most recent measurements are saved in the PSS, including measurements affected by setting HHT
outputs using Manual Mode below. The ASCII report generated provides a formatted table of voltage
and current levels for all signals.
Use the Electrical Test screens to verify that an E84 interface is electrically compliant. Input and output
signals must match the voltage and current levels defined in the E84 Specification. For signals in the
OFF state, voltage levels must remain above 1.8 VDC, with current levels less than 200 ?A. Signals in the
ON state must have voltage levels less than 1.8 VDC, with current levels greater than 200 ?A (typically in
the mA range).
