9/29/2015 ETH0621 ETH0621 6 digital inputs, 2 x 24V 5A digital output, 24V motor output at 5A and 2 x Relay outputs at 240vac 16A Technical Documentation Overview The ETH0621 offers 6 digital inputs (accepting 10V 24V), 2 independently switched 24V 5A outputs and a 24 volt, 5A motor controller that effortlessly integrates motion control over Ethernet. The ETH0621 also includes a motor surge protection circuit that shuts the motor down in the event of the current exceeding 22A.

9/29/2015 ETH0621 Having connected your 24vdc power supply and Ethernet connection, start up your web browser and type http://eth0621 into the address bar, please note this only works in windows. You will be prompted for a password as shown below: The default login is: Username: admin Password: password The ability to change these settings is shown in the configuration section You should now see the following web page: http://www.robotelectronics.co.uk/htm/eth0621tech.

9/29/2015 ETH0621 This web page will allow you to control the motor with the relevant buttons, switch the two relays, switch the two outputs and also monitor the inputs. Configuration By clicking the configuration link it's possible to configure the ETH0621 IP address and subnet mask together with the ability to set a password for entry to control screens. Gateway address and DNS address is configurable and is used with mapped inputs which are described in section below.

9/29/2015 ETH0621 Factory Reset Should it be necessary to reset the ETH0621 to its shipped condition then the end two contacts of the row of 5 holes nearest the Ethernet connection must be shorted together at board power up. The blue LED should then flash as the settings are reset, please wait until the LED finishes flashing and do not remove power during this period. Firmware Updates The firmware is fully updateable, this section will be expanded upon new firmware availability.

All authorised commands set the timer back to 30 seconds (including this one). 255 TCP/IP password is not enabled. IP Addresses & DHCP Servers The easiest way to use the ETH0621 is to connect it to a network with a DHCP server, in this case the ETH0621 will have its IP address assigned automatically by the DHCP server.

Visual studio express is provided free from Microsoft: http://www.microsoft.com/exPress/download/ Access from the Internet The ETH0621 can be controlled over the internet almost as easily as on your local network. Your network will most likely be connected to the internet with a broadband router.

9/29/2015 ETH0621 Now go to the "Firewall Rules" menu and click "Add" in the Inbound services section. Select the ETH0621 service and ALLOW always. The "Send to LAN Server" IP address is the ETH0621's IP address, 192.168.0.96 in the example above but check what it is on your network. Click "Apply" and that's it. The ETH0621 is now accessible over the internet. Before you close the routers setup pages, go to the "Router Status" menu and make a note of its ADSL port IP address.
