7.2 Local network with router and DHCP
If we plug in the CSMIO/IP-M controller into a computer network where a router allocates the IP addresses,
the device automatically downloads the address and network mask settings.
Usually there is no need to know what IP address was assigned to the device because the plug-in and the
application that updates the controller software automatically searches the CSMIO/IP-M in the network.
However if you want to know what IP address the controller has, you can find out from the router’s
configuration page (the controller is called
CSMIO-IP-xxxx, where xxxx are the last four figures of the MAC’s
hardware address). Here is an example screenshot of the DHCP server where you can see the CSMIO/IP
device in the network.
If you connect the CSMIO/IP-M controller to the network with router, you should use the non-crossover
cable (so called Straight Thru, or 1:1). The way of wiring is shown in the tab. below:
In most cases, the crossover cable attached to the device will also work, because most routers have the
cable type auto-detect function, so called AutoMDX. In any case, there will be no damage, even if the
router does not have the function mentioned above.
Remember to use shielded cables. Ethernet connection is highly resistant to interference but the shielded
cable should be used, especially if you use serves or spindles with large power.
