Section 2: General operation
Raw socket connection
Raw socket is a basic Ethernet connection that communicates in a manner similar to RS-232. The
instrument will always terminate messages with a line feed, but because binary data may include
bytes that resemble line feed characters, it may be difficult to distinguish between data and line feed
characters.
Use raw socket as an alternative to VXI-11. Raw socket offers a faster connection than VXI-11.
However, raw socket does not support explicit message boundaries, serial poll, and service requests.
To enable or disable a raw socket connection:
1. From the front panel, press the MENU key, and then select LAN > ENABLE > RAW.
2. Select either ON or OFF. After the power cycle reminder, you return to the LAN CONFIG menu.
3. Press the EXIT (LOCAL) key to return to the LAN MENU.
4. Turn the instrument on and off again to finalize the changes.
Check the LAN network settings
You can check the network settings for the instrument without making changes.
To check the network settings:
1. From the instrument front panel, select MENU > LAN > STATUS.
2. Use the navigation wheel to select the following network settings:
•
IP_ADDRESS: The IP address that the instrument is using to communicate over the LAN.
•
GATEWAY: The gateway address that the instrument is using to communicate over the LAN.
•
SUBNET: The subnet mask that the instrument is using to communicate over the LAN.
•
METHOD: Automatic or Manual. When this is automatic, the instrument assigns LAN settings
automatically. When this is manual, you need to set the LAN settings.
•
DNS: The DNS information.
•
MAC-ADDRESS: The Media Access Control address of the network interface card.
•
SPEED: The instrument automatically detects the speed of the LAN and adjusts its own settings to
match.
•
DUPLEX: The instrument automatically detects the duplex setting of the LAN and adjusts its own
settings to match.
•
Port: RAW-SOCKET, TELNET, VXI-11, or DST. Select the port type to see the assigned port number.
•
Password: The current password.
3. Press the ENTER key to view the setting.
4. Press the EXIT key once to return to the STATUS menu.
