The instruments include both RS-232C and LAN interfaces. This
manual describes the connection methods and settings for the
instruments. See the Application Disk (CD-R) for details of the
communications commands. Descriptions of the commands are
provided in both text and HTML format.
Use the following procedure to view the HTML format descriptions:

RS-232C
RS-232C is a serial interface standard established by the EIA
(Electronic Industries Association) which specifies the interface
between DTE (data terminal equipment) and DCE (data communi-
cations equipment). The instruments can send and receive remote
control signals and data to a PC (personal computer) using a sub-
set of this standard.
LAN
Local area networks (LANs) are systems that provide communica-
tions between PCs in a limited areas at particular locations, such
as offices, factories and schools.
The Ethernet 10BASE-T interface provided in the instruments is a
standard LAN connection interface that uses TCP/IP communica-
tions protocols. The 10BASE-T standard is defined by IEE 802.3i
as having a transfer speed of 10 Mbps. Connections are made by
twisted-pair cable, and are normally arranged in a star configura-
tion around a hub. The maximum cable length between a terminal
and the hub is 100 meters. The TCP/IP protocols are commonly
used for LANs, as they are the basis for the Internet as well. The
protocols are defined by RFC documents published on the Inter-
net.
PPP (RS-232C + Modem)
Connect a modem to the RS-232C interface for performing com-
munication based on PPP (Point-to-Point Protocol) over public
telephone networks or cellular phones via the modem in your PC.
