TVR1G
LAN Network Tester (10, 100, 1000 MB/s)

Introduction
Congratulations on your purchase of the Triplett TVR1G LAN
(Local Area Network) Ethernet Tester. Twisted pair cable is the
standard for local area networks (LANs). Its popularity stems
from its ease of use, cost, speed and maybe, most importantly,
adaptability. A 10 Base-T device, installed years ago,
communicates with a new gigabit switch (1000 Base-T) because
the standard that defines Ethernet LANs requires negotiation to
a common speed and duplex. For instance, a 100 Base-T, half
duplex PC connected to a 1000 Base-T, full duplex switch forces
the switch to negotiate "down" to 100 Base T, half duplex mode.
Verify this by connecting the TVR1G inline" between the two
devices and display the negotiated result. This inline capability is
remarkable and only available on other testers that cost over 7
times the price of the TVR1G. It also tests single LAN ports;
cables; tones cables; and detects Power over Ethernet (PoE).
But the inline test is one of its most popular.
Safety
WARNINGS
• Read understand and follow safety rules and operating instructions in the
manual before using this tester.
• The detection function of the tester may not be able to solve the user's
needs if not used in accordance with the manufacturer’s instructions.
• Do not operate tester if Low Battery warning occurs. Replace batteries
immediately.
• Please check the network cable type before using the tester to ensure that
it meets the requirements.
• Do not use if the tester appears damaged or if it is not operating properly. If
in doubt, replace the tester.
• Comply with all applicable safety codes.
•Please take care not to plug the cable test jack into a PoE
source or .damage may occur!

• Do not expose tester to extremes in temperature or high humidity.
NOTE: Before testing the PC network, you should first set up the
corresponding Ethernet card attributes, turn off the "energy-saving
Ethernet circuit" “Flow control” and then perform the test, otherwise it
will affect the test results. Please note that this is very important! ! !The
setting method is as follows:
[Settings] — [Network & Internet] — [Ethernet] — [Change adapter options] —
[Right mouse button local connection] — [Properties] — [Configuration] —
[Advanced] — [Energy-saving Ethernet] — [OFF] — [Flow control] — [OFF] — [OK]

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

forced to negotiate to 100Base-T half-duplex mode, and the final result
displayed by the tester is 100Base-T half-duplex.
POE Test
If the POE is provided by a switch that supports POE, when the power
pairs are on 1, 2 and 3, 6, this power supply method is called "POE
endspan". At this time, use a tester to test, the POE LED will be green, when
the power supply For 4,5 and 7,8, this power supply method is called "POE
midspan". At this time, use a tester to test, and the POE LED is displayed in
red.
Cable test
When the remote probe is not used, and only the main device is used
for cable testing, insert the cable into the cable test port to test whether there
is a LAN device at the other end of the cable. If the LED is on, it means that
the corresponding wire pair is connected to the device. (for example: LED "1
,2" and "4,5" are lit, indicating that the pair "1, 2" and "4, 5" are connected to
the device.)
If you connect the cable to the cable test port of the main tester and the
remote probe, you can observe the LED display to determine whether the
cable pair is connected, whether there is a wrong connection, the cable is a
straight-through cable or a crossover cable.
Cable Tracing
Connect one end of the cable to the cable test port of the main tester,
and use the remote probe to approach the cable will make a tone. If all four
pairs of the cable are wired, the tone will be more stable. The fewer pairs of
cables, The shorter the tone response time. Use this function to detect the
location of the required cable when the cable is bundled or the cable cannot
be determined.
Low Battery Indication
• If the power supply voltage is between 7.3v and 6.8v, the power LED will
flash continuously and slowly, and the instrument will enter the low voltage
mode.
• when the battery power of the tester is lower than 6.8v and cannot work
reliably, the power LED of the tester will flash ten times quickly and then turn
off. All LEDs are off and the tester cannot perform the test.
• Replace the battery to resume operation.

Auto Power Off (APO)
• To extend battery life, the tester will automatically shut down after
approximately 10 minutes of inactivity.
• When the power is turned off, the LED on the display panel will go out and
the test cannot be performed. If you need to test, please restart the tester.
Battery Replacement
1. Carefully unscrew the battery cover screw on the back of the tester and
open the battery cover.
2. Replace the battery with a 9V battery.
3. Carefully close the battery cover.
4. Screw the screw on the battery cover until it feels tight. Don't use
excessive force.
5. Use the tester to verify the speed and duplex mode of the LAN according
to the operating instructions.
6. If the battery power of the equipment is too low, please replace the
battery as soon as possible, otherwise the accuracy of the measurement
results may be affected.
Note: When inserting the battery for the first time, please remove the white
rectangular safety bar before installing the battery.
