Selecting a remote command interface
This section provides the details of how to use a remote command interface to connect to the
Series 2600A.
VXI - 11
This command interfaces provides message boundaries, supports serial poll, and serial request
(SRQ). You can expect a slower connection with this protocol.
Raw socket
Use as an alternative to VXI -11. Raw socket offers a faster connection than VXI-11. However, raw
socket does not support serial poll and serial request message boundaries.
Dead socket connection
Use the dead socket connection to manually disconnect a dead session on any open socket. This
forces the connection to close when the dead socket connection is closed.
Configuring a telnet connection
The Series 2600A supports the telnet protocol that you can use over a TCP/IP connection to issue
commands to the instrument. You can use a telnet connection to interact with scripts or issue
commands in real-time.
NOTE This example uses HyperTerminal available with Microsoft Windows
XP. Consult the help system for your version of Microsoft Windows to
identify a compatible tool.
To connect with the Series 2600A using HyperTerminal on a Windows XP system, complete the
following steps:
1. On the host PC, click Start > Accessories > Communications > HyperTerminal . A dialog
box similar to the one shown in Figure 16-5 should open.
