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.

Making Rear Panel Connections

The rear panel provides Passive and Active
E84 ports and a COM (RS-232) port.

Passive E84 Port

DB-25 socket housing (female) with 4-40
threaded jack screw locks. Pin assignments
per E84 passive equipment side. Provides
the interface for an external transceiver to
perform load and unload tests and
transceiver functional verification.

Active E84 Port

DB-25 pin housing (male) with 4-40 threaded jack screw locks. Pin assignments per E84 active
equipment side. Provides the interface to directly connect to a load port to perform load and unload
tests and electrical tests.

COM Port

DB-9 socket housing (female) configured as Data Terminal Equipment (DTE). Interfaces to GCI E84 Data
Logging Device (DLD) and RJ-11 Transceiver using a 9-pin straight-through male-to-female cable for DLD
log uploads, and live display mode.
