6.1.1 Program control interface
The 3943B monitoring receiver supports LAN remote control interface as described in the following
table:
Table 6.1 Remote control interface types and VISA addressing strings
Remote control
interface VISA address string (Note 1) Description
LAN
(Local Area
Network) Raw socket protocol:
TCPIP::host_address::port::SOCKET
The controller is
connected to the
instrument through the
instrument's rear panel
network port for remote
control.
For details of the
protocol, please refer to:
6.1.1.1 LAN interface
Note 1: VISA (Virtual Instrumentation Software Architecture), is a set of standard software interface
function library, by which the user can use the function library through the GPIB, RS232, LAN, USB and
other interfaces to control the instrument. Users shall first install the VISA library on the control computer
and use the VISA library to achieve remote instrument control. Please refer to the user manual of the
installed VISA library for details.
6.1.1.1 LAN interface
The monitoring receiver can be connected to 10Mbps/100Mbps/1000Mbps Ethernet using RJ45
communication cable (shielded or unshielded Cat. 5 twisted pair) for remote control via a control
computer in the LAN. The monitoring receiver has been installed with an interface adapter and TCP/IP
network protocol for remote control within the LAN, and configured with the corresponding TCP
protocol-based network services.
The network interface adapter installed in the 3943B monitoring receiver has three operating modes,
which are:

10 Mbps Ethernet (IEEE802.3);

100 Mbps Ethernet (IEEE802.3u);

1000Mbps Ethernet (IEEE802.3ab);
