4.5 Connecting 8743-CL to a Computer via Ethernet
4.5.1 Connecting to a Router
The 8743-CL Controller/Driver can be connected to an Ethernet Router. Attach the
computer Ethernet cable to the same router. If desired, the router can be attached to a
WAN (Wide Area Network) so that the computer can also be connected to internet, or
company network.
By default, the 8743-CL Controller/Driver is set for DHCP (Dynamic Host Configuration
Protocol). This means that, when connected to a router which is set in DHCP mode, the
router will automatically assign it a local IP address from the router address pool. The
computer will also receive a local IP address. The IP address normally will be in the range
of 192.168.1.1 to 192.168.255.255. Check your router settings to verify the IP address
pool.
As soon as both units, 8743-CL and computer, are connected to the router the Picomotor
Controller/Driver is ready to communicate with the computer. The discovery utility will
automatically find the IP address of the 8743-CL Controller/Driver and the user can start
sending commands to the unit. See Section 5 for details.
If several 8743-CL units have to be connected to the same computer the user can connect
them individually to an Ethernet hub or router. Alternatively, the first unit can be
connected to the router (or computer) with subsequent units daisy-chained as described in
Section 4.7.3 Using RS-485 LAN to Daisy-Chain.
