7 Functional Description
Press the [POWER] key to power on the EasyCheck 900
，
then select a function to begin
test. To turn the EasyCheck 900 off, hold the [POWER] key until the display turns off.
The EasyCheck 900 saves the last testing state after power off. When connecting
to unknown ports or cables, it is best to begin with Device ID test mode.
The following chapters will take you through every test function in details.
7.1
Device ID
The Device ID test identifies what equipment connected to the other end of the port
or cable. The test first looks for voltage being present on the connector pins.
If voltages are found in the telephone voltage range, the LCD will display this voltage.
If no voltage is detected, the EasyCheck 900 will check for Ethernet link pulses. If link
pulses are detected, the EasyCheck 900 will report the Ethernet information, i.e.
speed. The EasyCheck 900 default cable for connecting is a straight through cable.
In the case of a network card being connected to the other end of the Ethernet cable,
the EasyCheck 900 will
display
“
NIC
”
,
if
a
HUB or SWITCH is connected, the
EasyCheck 900 will
display
“
HUB
or
SWITCH
”
.
Warning
, if you use a crossover cable to connect the EasyCheck 900, the tester will
incorrectly
display
“
HUB
or
SWITCH
”
instead
of
“
NIC
”
.
In the case where the
EasyCheck 900 reports "Auto MDI/MDI-X', it means the remote device supports
auto-adapting crossover and straight through cables.
Press [OK] to start a new test.
7.2
Cable Test
Connect a Remote to one end of the cable and the EasyCheck 900 to the other end for
a full cable test. Without a remote on the other end, the EasyCheck 900 will
automatically perform a one-end test.
One-end test mode can only diagnose cable faults for shorts and split pairs, but is
unable to display the wiremap. The EasyCheck 900 will automatically perform a new
test every 3 seconds with
“
Testing
”
being displayed. To ensure correct results,
connect the cable to be tested before testing.
