Telnet connection
The Telnet protocol is similar to raw socket, and can be used when you need to interact directly with
the instrument. Telnet is often used for debugging and troubleshooting. You will need a separate
Telnet program to use this protocol.
The Models 707B and 708B supports the Telnet protocol, which you can use over a TCP/IP
connection to send commands to the instrument. You can use a Telnet connection to interact with
scripts or send real-time commands.
To enable or disable a telnet connection:
1. From the front panel, press the
MENU
key, and then select
LAN > ENABLE > TELNET
.
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.
VXI-11 connection
This remote interface is similar to GPIB and supports message boundaries, serial poll, and service
requests (SRQs). A VXI-11 driver or NI-VISA
TM
software is required. Test Script Builder (TSB) uses
NI-VISA and can be used with the VXI-11 interface. You can expect a slower connection with this
protocol.
To enable or disable a VXI-11 connection:
1. From the front panel, press the
MENU
key, and then select
LAN > ENABLE > VXI11
.
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.
Raw socket connection
Raw socket is a basic ethernet connection that communicates in a manner similar to RS-232 without
explicit message boundaries. The instrument always terminates 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
.
