    Plug the line cord into the connector on the rear of the instrument as shown in Figure 2-2. The instrument operates on any line voltage between 107 and 264V ac (45 to 65 Hz) without adjustment. Fluke warrants the instrument to meet specifications only at 50 Hz and 60 Hz operation. Power consumption is a nominal 15 watts.

  • Page 39: Dc Power

    DC Power The instrument operates from any dc voltage between 9 and 16 volts. Power consumption is a nominal 6 watts. To connect the ALARM/TRIGGER I/O connector to the rear panel, complete the following procedure: 1. Remove the ALARM/TRIGGER I/O connector from the packing material or instrument rear panel.

This chapter provides instructions on managing configuration information for NetDAQ Logger. Chapter 4 provides details on operating NetDAQ Logger: starting and stopping the instruments, managing data files, and optimizing performance.

  • Page 98: Configuring Network Communications

    Users Manual Configuring Network Communications Before you can configure the instruments on your network and create setup files for these instrument configurations, you must configure your network communications. This involves identifying the instruments by their BCN numbers and, on a general network, their IP addresses. Network configuration data is not saved as part of the setup files but is its own separate file, ccf.cfg, maintained by NetDAQ Logger.

  • Page 99: The Communications Configuration Dialog Box

    The Communications Configuration Dialog Box Use the Communications Configuration dialog box (Figure 3-2) to record your network configuration.

Now, the increased processing capability of affordable host computers, increased channel measurement rates, and pressure to place the instruments close to the signal source have made support of high-speed, long distance communication techniques necessary.

Will all the routers route IP packets? 4. What are my domain and host names (optional)? The minimum information you need to get is the IP Addresses for the PC and the instruments.

For any protocol, the Packet consists of a destination address, a source address, some protocol type information, a message length field, and error detection information.
  • Page 269 The IP address provides two pieces of information: the network ID and the host ID. The network ID must be unique among all network subnets within a connected Internet. It identifies the network subnet to which a host is connected. The host ID must be unique among hosts within a network subnet and identifies the host within the subnet.
