Flow Control
You can enable or disable flow control.
• ON: Flow control is enabled.
• OFF: Flow control is disabled.
MDI
You can set the measurement port to straight or crossover mode. This setting is valid when Test
Interface is set to RJ-45.
• MDI:
Straight
• MDI-X: Cross
• Auto: The AQ1300/AQ1301 switches between straight and crossover mode automatically (this
setting is valid when Negotiation is set to Auto).
Link Setting Acquisition
If the interface is SFP(GbE) or RJ-45, you can acquire and display link setting information of the
other device (DUT; the device on the user side) connected to the AQ1300/AQ1301.
• Acquired Link Setting Information
• Negotiation: Auto, Manual
• Speed: 1G, 100M, 10M
• Duplex: Full, half, −−− (when negotiation is set to manual)
• MDI: MDI, MDI-X
The AQ1300/AQ1301 acquires the speed, duplex, and MDI when Test Interface is set to RJ-45.
• Acquisition Status
The acquisition status of the other device’s link setting information is indicated as follows:
Preparing, Finish, Fail
• UTP Cable Type
When the measurement interface is RJ-45, select which type of UTP cable you are using.
Straight, Cross
• UTP Cable Status
Indicates the UTP cable status as follows.
Normal, The cable may be defective. It is two-pair cable
• Applying Link Settings
You can apply the acquired other device’s link settings to the AQ1300/AQ1301. You can do this
when the measurement interface is RJ-45 or SFP(GbE) and the acquisition status is Finish.
• Auto Detection of Auto Negotiation Configuration Mismatch
If the “Detect a mismatch of Auto-nego settings” check box on the link setting screen is selected
and the auto negotiation configuration between the AQ1300/AQ1301 and the other device is
not matched, the background of “LINK” in the link status area of the measurement screen (see
section 2.1) turns yellow.
Detection occurs at the following times.
• When a setup file is loaded (including when logged in)
• When link settings are changed
• When link changes from link-down to link-up
