81943A041-1 Single ended amplifier voltage 280V


It seems like you’ve provided detailed instructions on how to establish and check the communication between the spectrometer and a computer through an Ethernet connection. Here’s a summary of the key points:

  1. Ethernet Interface and Cable Types:
    • The spectrometer communicates with the computer through an Ethernet interface (cable).
    • Two types of cables are provided: Crossover cable for a direct connection to the PC and Straight pin cable for a connection via a network.
  2. Connection Checking:
    • If the spectrometer is not connected to the computer or network (DHCP server), restart the spectrometer to establish a proper connection.
    • The Network LED on the spectrometer should turn green when properly connected, and flashing indicates activity.
    • Each spectrometer has a unique MAC address for identification.
  3. Ethernet Connection Setup:
    • The computer delivered with the spectrometer is factory-configured for proper connection.
    • Two possible setups:
      • Spectrometer connected to the network.
      • Spectrometer directly connected to the computer, which requires a pre-configured LAN setup for both.
  4. IP Address Configuration:
    • If the spectrometer cannot detect a DHCP server, it will use a default IP address.
    • Example default IP address: with a subnet mask of
    • The PC Ethernet interface should be configured with compatible LAN parameters.
  5. Configuration Procedure:
    • Open Start > Settings > Network and Dial-up Connections.
    • Right-click Local Area Connection in the Network Dial-up connections window and select Properties.
    • In the Properties dialog box, select Internet Protocol (TCP/IP).

It appears to be a comprehensive guide for ensuring proper communication between the spectrometer and the computer through the Ethernet interface, covering cable types, connection checking, and IP address configuration.
