    4 CONNECT TO NETWORK 4.1 LAN Cable The LAN cable must be supplied by the customer. It may be a standard straight “patch” CAT-5 (or better) network cable or it may be a “crossover” cable where the pins are reversed on one end. The cable type is auto-detected by the power supply.

  • Page 12: Power-Up The Lan Power Supply

    4.3 Power-up the LAN Power Supply The Z power supply LAN option automatically detects if it is connected or disconnected from a network. It will also automatically look for a network server and it will retrieve or create an IP address.

  • Page 13: Hostname

    4.5 Hostname The hostname is a text address instead of a numeric address (for example: Z10-40-29B). This address mode is less common than the IP address because the hostname cannot be viewed from the front panel, and because a naming service (such as NetBIOS) must be running in the LAN computer.

    Subnet Mask Displays the subnet mask assigned to the power supply through either DHCP, Auto-IP or Static IP. Default Gateway Address of the network router to allow the power supply to communicate outside of the local subnet. DNS Server Address of the server running the Domain Naming Service. This is used for hostname addressing. Hostname The power supply hostname may be used instead of the IP address to create a communication link.

    TCP/IP Mode This selects how the power supply receives network settings. Select either: • DHCP Assigned / AUTO IP: If this mode is selected, the network server uses DHCP to assign the IP address, subnet mask, default gateway and DNS server. Since the server assigns these, they are disabled (gray) on the web page.

    LAN Keep-Alive If you are logged in this is how many seconds the web pages may be inactive (idle) before the power supply automatically logs you out. The default is 1800 seconds = 30 minutes. Ping Server ‘Ping’ is a network utility that allows the computer to verify communication with the LAN power supply.

    8 PROGRAMMING USING SOCKETS 8.1 Socket Description The VISA drivers for the Z power supply with LAN are popular in the Test and Measurement world. However, some customers cannot use VISA because of installation or licensing issues or because the controller (i.e.: industrial PLC) does not support VISA. If you cannot use VISA drivers, then the Z with LAN offers socket connections.

    8.5 Message Terminators When you are using a program that sends separate SCPI commands out through a TCP socket, the socket drivers may combine all the messages into one long packet. Therefore, it is necessary to add a terminator character to the end of each SCPI command. All SCPI commands must have a terminator character.
