How do I connect my Vista and Computer using an RS-232 Ethernet Adapter?


Method #2

Materials Needed:  Vista Firmware needed: 01.0014 and above

Ethernet cable

Crossover adapter

Ethernet to RS-232 Connector

RS-232 to USB (optional)


  • Configure Ethernet to RS-232. Set up Ethernet to theRS-232 adaptor with static IP address and Port Number. In this example, the adapter was configured with IP address of and port 10001.

Connect Vista to Computer

  • Plug Ethernet cable into RJ-45 Ethernet connection at rear of Vista. 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.


Configure the Vista: (Requires Essentials Rev 14 or higher)

  • Configure the ethernet port of Vista. Select Jobs > Preferences and Select 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 Jobs > Preferences, check Automatic Network Data Export and click to configure. For a direct connection between Vista and data collection computer, set up the Vista as a Client. Set the IP Address to match the settings of the Ethernet to RS-232 converter, in this case and the Port as 11111. Press Apply and then press Apply on the Read Options screen to continue.

Configure the Computer:

  1. Connection configurations differ depending on data collection software. In this example, Hyperterminal is used to demonstrate connectivity. 
  2. The data collection computer will be set up as a Server.
  3. 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

To Export Data from the Vista:

  1. 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 and data will be transferred to the computer.

<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>
