Purpose: Shows how to connect the Vista to a Computer using a RS-232 Ethernet Adapter.

Answer:

Method #2 - Materials Needed:

  • Ethernet cable
  • Crossover adapter
  • Ethernet to RS-232 Connector
  • RS-232 to USB (optional)

 

  1. Configure Ethernet to RS-232
  • Set up Ethernet to the RS-232 adaptor with static IP address and Port Number.
  • In this example, the adapter was configured with IP address of 192.168.0.100 and port 10001 (You can use 11111 as well, as long as the number is same in Client and Server).
  1. Connect Vista to Computer

  • Plug Ethernet cable into RJ-45 Ethernet connection at rear of Agera. Plug other end of cable into Crossover Adapter.
  • Plug Crossover Adapter into Ethernet port of Ethernet to RS-232 adapter.
  • Plug Ethernet to RS-232 adapter into serial port of computer (if D-9 serial port is present) or into RS-232 to USB converter for connection to USB port. Plug power into Ethernet to RS-232 adapter.

3. Configure the Agera:

  • Configure the Ethernet port of Agera. Select WORKSPACE > PREFERENCES > CONFIGURE NETWORK SETTINGS. Uncheck Use DHCP for Ethernet Config and enter a valid IP address for the Ethernet port. In this example, the following parameters are selected.


  • Press APPLY on the Ethernet Configuration and then APPLY on the Preferences Page to complete.
  • Go to WORKSPACE > PREFERENCES, check AUTOMATIC NETWORK DATA EXPORT and click to configure.

 

Preferences > Automatic Network Data Export

  • For a direct connection between Agera and data collection computer, set up the Agera as a Client.
  • Set the IP Address to match the settings of the Ethernet to RS-232 converter, in this case 192.168.0.100 and the Port as 10001(You can use 11111 as well, as long as the number is same in Client and Server). Press APPLY and then press APPLY on the Read Options screen to continue.

  1. Configure the Computer:
  • Connection configurations differ depending on data collection software. In this example, HyperTerminal is used to demonstrate connectivity.
  • The data collection computer will be set up as a Server.
  • Connect as follows:
    1. Select the Com port that represents the USB or Serial port connection.
    2. Define the Connection:
    3. Bits per second: 9600
    4. Data Bits: 8
    5. Parity: None
    6. Stop Bits: 1
    7. Flow Control: None
    1. Send Data from the Vista:
    • Configure the Color Data Table with the color scale and parameters to be transmitted.
      1. Standardize the Instrument
      2. Select Color Scales, Indices & Illuminant/Obs (Workspace>Color Scales)
      3. Hit Read Button, data will be transferred to the computer.

      • The data string is shown as follows:
      <STX><PACKET SIZE>$T<SCALE-LABEL>$T<ill/Obs>$T<LABEL NAME1><$T><VALUE1>$T<LABEL NAME2><$T><VALUE2><$T><LABEL NAME3>$T<VALUE3>$T ..... <LABEL NAME N><$T>

<VALUE N>$T<CHKSUM><ETX>

 Where,

<STX> is the Start of Text (value =0x02)

<ETX> is the End of Text (value =0x03)

      $T is the default delimiter.

      <SCALE-LABEL> is the Scale Label (e.g., CIELAB)

      <ill/Obs> is the ill/Obs name (e.g., D65/10)

      <PACKET SIZE> is the Total size (HEX String) of the Packet excluding the <STX> and <ETX>

      <LABEL NAME> is the label name (e.g., L*, a*, b*, dE* etc..)

      <VALUE> is the value for the preceding Label Name

      <CHKSUM> is the Checksum (HEX String) - the sum of all the ASCII values in the total packet play load starting from <PACKET-SIZE> and till <CHKSUM>
