17. PCMCIA ETHERNET FUNCTION
975
This section describes troubleshooting and check items associated with
the PCMCIA Ethernet function.
1) Is an STP cable used for connection between the hub and PCMCIA
Ethernet?
2) Is the STP cable connected correctly?
In general, a straight cable is used for connection between the hub and
communication device.
For direct connection to the personal computer without using the hub,
a cross cable is used.
3) Is the power to the hub turned on?
4) The PCMCIA Ethernet card is used only with 10BASE–T. Is a hub
for 10BASE–T used when the PCMCIA Ethernet card is used?
5) Is the LED (for link display) of the connected hub turned on?
(Some hubs are not provided with a link LED.)
The LED is not turned on when the hub is not connected with the
PCMCIA Ethernet or the power to the CNC is not turned on.
This subsection describes how to check the minimum settings required
for communication.
Checking the settings on the PCMCIA Ethernet side
1) Is the MAC address of the PCMCIA Ethernet displayed?
S A unique MAC address is assigned to each PCMCIA Ethernet card.
When a PCMCIA Ethernet card is selected and inserted, MAC
address display is provided.
2) Is a correct IP address set?
S Check if an IP address already specified for another device is set.
3) Is a correct subnet mask set?
S The subnet mask setting must match the subnet mask setting on the
communication destination device.
4) Is a correct router IP address set when communication via a router is
performed?
Checking the settings on the personal computer side
1) Is a correct IP address set?
S Check if an IP address already specified for another device is set.
2) Is a correct subnet mask set?
S The subnet mask setting must match the subnet mask setting on the
communication destination device.
3) Is a correct router IP address set when communication via a router is
performed?
