2 Network connection and Http access

3 Accessing the ETH008 from your browser Having plugged in your 12vdc power supply and Ethernet connection the board will power up and request an IP address from the DHCP server, if no server is present then the board will default to IP address Now please start up your web browser and type 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. This web page will allow you to switch the relays on and off by clicking the relay buttons (the red/gray circles). It also contains a links to this technical documentation page, the network configuration and mapped inputs. Configuration By clicking the configuration link it's possible to configure the ETH008 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. The configuration page also offers the option to set a password that will be required to change any of the relay states or digital outputs using TCP IP commands, this is explained in the TCP/IP password section. All settings are saved to memory so be careful to remember the username and password! Default password settings are shown in the picture below. Version 4 now offers a latched outputs option, this will automatically save any permanent output changes (not pulsed) and restore them following power loss.

4 HTML commands DOAx and DOIx (V4+ firmware needed) A customer requested feature, allowing the digital outputs to be switched by the Http get function such as used in some voice over ip phones (VOIP). You can use the Http get function to write to the io.cgi file with the following syntax: /io.cgi?DOA2=10 This would use the default address ( ) and make output 2 active for 1 second. Another example would be to set output 1 inactive for 10 seconds: /io.cgi?DOI1=10 You can test these functions by typing them directly into the address bar of most internet browsers. Also be aware that you may need to disable Http authentication in the Http configuration if your control device does not support it.

5 TCP access and commands The command set designed to provide consistent expansion and new features, they are sent over TCP/IP on port (0x4456). This is the default port, it can be changed in the configuration settings. Five connections are allowed at any one time, these are independently protected but all using the same password as defined in the board configuration. Digital Active/Inactive Commands These are 3 byte commands: The first byte is the command, 32 (active means on) or 33 (inactive). Second byte is the output number, 1-8 for the relays. Third byte is the on time. Set this to zero for non-pulsed mode, or for a pulse in 100mS intervals (100mS to 25.5 seconds). For example: 0x20 - turn the relay on command 0x03 - relay 3 0x32 (50) - 5 seconds (50 * 100ms) Board will return 0 for success, 1 for failure. Note - All bytes in a command must be sent in one TCP/IP packet. TCP/IP Password If this option is enabled in the Http configuration page then a password will be required to be entered before relay states can be changed. In the following example the password was set to "apple": 0x79-1st byte in frame sent to ETH008 to indicate password entry 'a' (0x61) - 2nd byte in frame (ASCII hex equivalent in brackets, 'p' (0x70) - 3rd byte in frame 'p' (0x70) - 4th byte in frame 'l' (0x6C) - 5th byte in frame 'e' (0x65) - 6th byte in frame These 6 bytes are then transmitted in the same transaction to the ETH008 and if the password is correct then 1 will transmitted back, a failure will send 2. The board will now accept changes from the device that entered the password. If communication becomes idle for more than 30 seconds then the password protection is re-enabled. There is also a logout command of 0x7B to enable the protection immediately.

6 Get Unlock Time Returns TCP/IP password protection status: 0 - password protection is enabled and password entry is required before changes can be made seconds until TCP/IP password protection is re-enabled. All authorized commands set the timer back to 30 seconds (including this one) TCP/IP password is not enabled. ASCII text commands DOA and DOI (V4+ firmware needed) Following customer request we have added a feature that allows the outputs to be switched using an ASCII string, devices like a Mobotix camera can now switch relays with simple strings. The string for activating output1 for 5 seconds is formatted using comma separated variables with the following syntax: ":DOA,1,50,password" To break this down ":" (0x3A) at the start of the string indicates that there is an ASCII message to follow, "DOA" is digital output active, "1" is the output number, then "50" for 5 seconds (50 * 100ms) and finally the TCP password (if applicable). If I wanted to make output 2 inactive for 3 seconds I would use: ":DOI,2,30,password" To break this down ":" (0x3A) at the start of the string indicates that there is an ASCII message to follow, "DOI" is digital output inactive, "2" is the output number, then "30" for 3 seconds (30 * 100ms) and finally the TCP password (if applicable). Assuming no password is used the previous command would simply be: ":DOI,2,30 " אי.די.פי מוצרי זיהוי אלקטרוניים בע"מ תושיה 6, תל-אביב, 67218, טל: , פקס: idp@idp.co.il Web:
