Figure 4-3 Switches on the WT Adapter
(a) [TEST SW] switch
This is the switch to check for any disconnection on the Ethernet cable connecting the
WT and WT adapter.
The connection of the ETHER signal line (4) in the Ethernet cable (8) can be confirmed.
If you turn on this switch, the Ethernet signal is looped back to the WT and not output to
the PC port.
How to check for a disconnection:
• connected to cable between WT and WT adapter, and turns on the power supply with
the AC adapter.
• Unplug the cable from the PC port of the WT adapter.
• Make sure that the ETHER LED lights.
• Hold down the TEST SW switch.
• (The Ethernet signal from the WT is looped backed to the WT via the WT adapter.)
• The connection is normal if the ETHER LED lights green.
• The four Ethernet signal lines have a disconnection or wrong wiring if the ETHER LED
remains extinguished.
・
The TEST SW cannot identify a wrong connection for the straight/cross cable. When
connecting a connector, make the correct connection for the straight or cross cable.
If you turn on this switch by mistake, the Ethernet signal is looped back to the WT and not
output to the PC port.
