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.
Warning
Do not connect the instrument to the public telephone
system. If you do, damage can occur to the LANMeter
instrument.
