PLZ-5W Series Electronic Load

Commnunication Interface Mannual



Setting Up the LAN Interface

Either the VXI-11, HiSLIP, or SCPI-RAW protocol can be used to control the PLZ-5W via the LAN interface. For VXI-11 and HiSLIP, the middleware is installed automatically by the VISA library. For SCPI-RAW, no middleware is required.

The LAN interface board has a Web browser interface. You can configure the LAN interface settings from your PC's Web browser.

For information on topics such as connecting to your corporate LAN, your IP address, your host name, and security, contact your network administrator.

If you are using a host name (a Bonjour host name), you have to install Apple Bonjour.

Connection Procedure

Use a standard LAN cable (category 5 and straight) to connect the PLZ-5W to a network hub or router.

Setting Procedure

1.    Press SYSTEM and then Configure Interface on the front panel.

If the Interface screen does not appear, press Configure Interface again.

2.     Press Modify and make the necessary LAN settings for “IP Address”, “DNS Server”, “WINS Server”, and “Hostname & Services”.

Normally, use the PLZ-5W with “Method” under “IP Address” set to “Automatic” (factory default setting). If this settings have been changed, execute Resetting the LAN Interface Settings to restore the factory default settings.

You can check the IP address by pressing SYSTEM and then Information on the front panel.


Possible damage to the equipment and electric shock. The LAN interface can be accessed from anywhere on the network that the PLZ-5W is connected to. If necessary, set a password for the Web browser interface.
