Operation
LAN Speed and Type Verification
The tester has three ports for LAN testing, the left port and the middle
port are straight-through connections, and the right port is cross-connected
to the other two ports. When performing a single-port test, the left port and
the middle port are commonly used choices. When performing an inline
mode test, select the left port and the middle port to establish a direct
connection between the two devices, select the left port and the right port to
establish a cross connection between the two devices.
Single Port Test
All three LAN test ports can perform single-port test. Insert the LAN
device into the port, LINK will display whether the received data is from HUB
or PC. PC indicates that the device is transmitting on pins 1 and 2, and HUB
indicates that the device is transmitting on pins 3 and 6.It should be noted
that:If it is connected to a cross port, the actual situation of the device will be
opposite to the displayed result.
SPEED VERIFICATION has four gears (10/100/1000/10000 MB/s)
which will display the network speed and type of the device. The LED shows
red to indicate that the LAN type is half-duplex, and the LED shows green to
indicate that the LAN type is full-duplex.
For example: the 100-level LED is displayed as two greens, indicating
that the LAN device network type is 100MB/s full-duplex.
Inline Mode Test
Connect two LAN devices into the tester by inline method. Before
connecting two devices in series, you should use a single port to test a single
device, make sure that one of the LED in both columns is lit, and make sure
that there are no problems with the cable and the device. , if only one column
of LED is lit, there is a problem with the test.
After the check is correct, connect the two LAN devices in series, the
tester will detect the communication speed and mode of the two devices,
negotiate the final result according to the conditions of the two devices and
display it through the LED, and the DATA display indicates that the device is
inside In connection mode, SPEED VERIFICATION will display the speed
and type of connection between two LAN devices.
For example: A 1000 Base-T full-duplex switch is connected to a 100
Base-T half-duplex PC. Due to the Ethernet LAN standard, the switch will be
