Serial Test; 100 Mhz Cable Remote Test; Attaching Cables - Fluke 686 Getting Started

68x Series
Getting Started

Serial Test

When running the LANMeter Serial Test, attach a loopback connector to the
Serial connector on the lower left-hand side of the instrument. To make a
loopback connector, take a female DB-9 connector and connect jumpers
between pins 2 and 3 and between pins 6 and 7. Verify that all tests pass.

100 MHz Cable Remote Test

This test requires the optional 100 MHz Cable Remote. When running the 100
MHz Cable Remote Test, attach the supplied ScTP Cat 5 Patch Cable between
the LANMeter instrument's TO HUB/MAU (686/685) or TO Hub (683/682)
and the 100 MHz Remote. Verify that all tests pass.

Attaching Cables

You attach cables to the instrument in one of the following three
configurations. The configuration that you use depends on the test you want to
run.
r TO MAU, TO HUB, or BNC Connection
r TO NIC Connection
r Expert-T Autotest Connection
The instrument lights the MAU (or HUB) and/or NIC LEDs on the top-front of
the instrument to indicate which of the LAN connectors you should use for the
selected test. The Fluke 680 has a MAU LED, the Fluke 683 and 682 have a
HUB LED, and the Fluke 686 and 685 have a HUB/MAU LED. Figure 2
shows these LEDs on the instrument's user interface.
On the Fluke 686, 685, and 680 there are two TO MAU (or TO HUB) and two
TO NIC connectors, as shown in Figure 1. Each pair consists of an RJ-45 and
DB-9 type connector that are connected in parallel. Use only one TO MAU or
TO NIC connector at a time. If your network uses BNC connectors, use the
BNC connector as shown in Figure 1.
Do not connect the instrument to the public telephone
system. If you do, damage can occur to the LANMeter
instrument.
