may not exactly match the blink rate of the LanMaster 26. Determine the blink
pattern directly at a hub/switch port prior to running tests from a remote outlet.)
The Link light on the NIC will light verifying two-way Link communications.
If no signals are detected, the LAN and NIC indicators illuminate red
continuously.
aUtO-nEGOtIatIOn
When two or more operational mode indicators are lit, the Link being
tested is capable of Auto-negotiating to the highest common level of opera-
tion with a Link Partner.
After the LanMaster 26 begins transmitting Link signals, the Link Partner
will Auto-negotiate to the highest common mode and the LanMaster 26
indicator for that mode will light, verifying the Auto-negotiation function. (Note:
Auto-negotiation timing varies greatly, therefore, not all equipment will complete
Auto-negotiation with the LanMaster 26. For equipment with long time con-
stants, the capabilities are displayed but the negotiation to the mode does not
occur. Test a known good port to determine equipment response time.)
lInK SIGnal tYPE
Three different signals can be used to
establish a Link: a Link Code Word, an NLP or
an MLT-3 waveform. The Link Code Word is
specific in both Link speed and duplex mode.
1000BaseTX Links always use Link Code
Words. The NLP is specific in speed (10Mbps)
but ambiguous in duplex mode (half or full).
The MLT-3 waveform is also specific in speed
(100Mbps) but ambiguous in duplex mode.
Duplex modes for equipment that use NLP or
MLT-3 signaling must be carefully managed to ensure proper Link operation.
Example: Most 10/100 switches, when configured to either 100Mbps full
duplex or half duplex mode, use the same MLT-3 signal to setup a Link. If a
switch port that is set to 100Mbps full duplex is connected to a NIC set for
Auto-negotiating, the NIC will establish a half duplex Link based on the MLT-
3 signal from the switch. The duplex configuration mismatch will cause the
Link to perform poorly due to high error rates and collisions.
The LanMaster 26 indicates an MLT-3 signal by alternately blinking
the 100TX and 100FD indicators. An NLP signal is indicated by alternately
blinking the 10TX and 10FD indicators. When this condition exists, the Link
Partners must be configured as follows:

English
-same speed and duplex mode
-one in half duplex mode and one in Autonegotiation mode
-both in Auto-negotiating mode
for the Link to operate properly. Duplex mismatch is a common network
problem. For improved network management, the LanMaster 26 warns the
user when ambiguous duplex mode Link signals are detected.
battERY lIFE
Auto Power Down – The LanMaster 26 will automatically turn off after
approximately 10 minutes of operation.
