You can use the communication functions listed below through the RS-232C, LAN interface
equipped as standard on the instrument. This manual explains how to connect the commu-
nications cable and the settings on the instrument.
In order to connect the instrument to a PC, prepare the sold separately 9612 RS-232C
CABLE (for personal computer), 9721 RS-232C CABLE (for modem), and 9642 LAN
CABLE.
*1 During measurement using a program created in Visual Basic, for example, remote
operation by a HTTP server is not possible.
*2 Email may not be sent depending on your Internet service provider. In such case, send
mail via the intra-network mail server using a LAN.

Overview

LAN Interface • Compatible with IEEE802.3 Ethernet 10BASE-T DHCP, DNS
• Screen display, remote control via HTTP server
• Acquiring data from internal memory or PC card via FTP server
• Email notification delivered at time of alarm
RS-232C Interface
• Conforms with ETA RS-232C, mini DIN round 9-pin connector
• Communication function via PPP connection (functions similarly to
LAN connection)
RS-232C
RS-232C is a serial interface standard established by the EIA (Electronic
Industries Association) which specifies the interface between DTE (data ter-
minal equipment) and DCE (data communications equipment). The instru-
ments can send and receive remote control signals and data to a PC
(personal computer) using a subset of this standard.
LAN
Local area networks (LANs) are systems that provide communications
between PCs in a limited areas at particular locations, such as offices, facto-
ries and schools.
The Ethernet 10BASE-T interface provided in the instruments is a standard
LAN connection interface that uses TCP/IP communications 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 configuration 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 Internet.
PPP
Connect a modem to the RS-232C interface for performing communication
based on PPP (Point-to-Point Protocol) over public telephone networks via
the modem in your PC.

Through RS-232C communications, you can send communication commands from the PC
and perform remote control and send/receive data. (⇒p. 31) For communications, set the
instrument's Comm screen to the same settings as the PC to connect to.
1. Connect the 9612 RS-232C CABLE to the instrument's RS-232C connection ter-
minal.
2. Connect the RS-232C cable's connector to the PC.

RS-232C Communications
RS-232C Connection
The 9612 RS-232C CABLE and the instrument connectors should be
mated carefully. Forcing the connectors together can damage the con-
tacts.
The RS-232C interface is not isolated from the instrument chassis.

Remote control is provided by commands sent from the controlling PC. RS-232C settings
are made on the instrument. These settings must match those on the PC to enable commu-
nications.
1. Press and open the Status screen, and move the blinking cursor to
[Comm] with .
2. Press and open the Comm screen.
3. Press and move the blinking cursor to [Communication Interface], and
open the selection window with .
4. Press / and select [RS-232C], and set with .
To cancel, press .
5. Set each of the items continually.
• If overrun or framing errors occur, reduce the communications speed.
• Do not attempt change settings while communications are underway.
