1. General
This instrument can be operated by remote control through an external controller (usually a personal
computer) in almost the same way as when you operate it manually using buttons.
Data on measurement results and panel setup can also be transferred by remote control. So you can
collect data using a personal computer and configure the automatic measurement system.
2. Remote Control
There are four methods for operating this instrument by remote control:
(1) Remote control by using the standard USB with which this instrument is equipped
(2) Remote control by using the standard LAN (TCP/IP) with which this instrument is equipped
(3) Remote control by using the RS-232 interface
(4) Remote control by using the GPIB interface
The following interfaces are factory options.
RS-232LAN interface ：SC-361
GPIB interface ：SC-363
Interfaces used remotely are set by using REMOTE from the SYSTEM menu of this instrument. Refer
to the following sections for the setting and control methods of each interface.
USB interfaces are standard on the majority of personal computers and are therefore a useful method
of remote control. However, note that the connection cable length poses a limitation.
LAN interfaces are also standard on the majority of personal computers, and can be used by
connecting to an existing network environment instead of by directly connecting a cable. However,
this method requires a unique IP address to be assigned to this instrument.
2.1 Restrictions of remote control
It is possible to remotely control almost all of the functions provided on this instrument.
However, the power switch ON/OFF, various settings about remote interface in the SYSTEM menu,
offline browse function and VALUE TO USBMEM function etc. cannot be controlled remotely.
For details about functions operated through the remote control and control commands, see Chapter
3, Remote control commands.
2.2 Remote/local control
A state, in which each function of this instrument is remotely controlled by messages sent through the
interface, is called “remote mode”. On the contrary, a state, in which the instrument is operated by
panel key entries, is called “local mode.”
In the remote mode, all panel keys except for the LOCAL(SHIFT]) key become invalid. At this time,
the REMOTE indicator is displayed in the annunciator.

2
Shift to remote mode
< SCPI conforming >
When the command system shifts to remote mode in accordance with SCPI (When "SCPI" has
been selected with COMMAND of the SYSTEM-REMOTE menu), this instrument does the
following behavior.
- It becomes a measurement halt state. Use the command (INITiate command and READ? query,
etc.) that changes to the trigger waiting state when measuring. (Refer to "3.5.4 TRIGger
subsystem" for details.)
- Offline browse state is released.
- If the bulk log is being executed, the bulk log is stopped.
- The setting of an external trigger is changed according to the remote setting of the trigger
source.
< VOAC752x series conforming >
When the command system shifts to remote mode in accordance with IWATSU (When "IWATSU"
has been selected with COMMAND of the SYSTEM-REMOTE menu), this instrument does the
following behavior.
- It is changed to the value that can be set for the item to which use remotely in accordance with
the VOAC752x series like a part of sampling rate and the bulk log, etc. is limited. (Refer to
"3.7.1.2 Limited function " for details.)
- The preservation of the log (Depend on the SAVE:STAT command) is changed according to the
ON/OFF setting of the data store.
Shift to local mode
Execute after confirming the action of all command/query transmitted till then is completed by
using * OPC? query (Refer to section 3.4.5) etc. when switching to the local mode. The
unanticipated operation may be caused when shifting to the local mode without waiting for the
completion of processing.
< SCPI conforming >
When the command system shifts to local mode in accordance with SCPI (When "SCPI" has been
selected with COMMAND of the SYSTEM-REMOTE menu), this instrument does the following
behavior.
- The setting of an external trigger returns to the state when not depending on the setting of the
trigger source remotely, and having set it in the local at the end.
< VOAC752x series conforming >
When the command system shifts to local mode in accordance with IWATSU (When "IWATSU"
has been selected with COMMAND of the SYSTEM-REMOTE menu), this instrument does the
following behavior.
- It doesn't depend on the ON/OFF setting of the store of data (Depend on the SAVE:STAT
command), and it becomes log mode NORMAL operation (always preservation operation).
In the method of switching local mode / remote mode, there are different parts in each interface.

2.3 Remote control using USB
This instrument can be operated through remote controls by using a USB interface by
connecting the USB port on the back panel and a computer. You can obtain the driver and
sample application that can be used with the computer from the Iwatsu website (URL:
http://www.iti.iwatsu.co.jp). See the website for details.
Use a USB 2.0 A/B cable to connect this instrument to a computer.
Note: A cable for noise reduction (shielding) may be required and is recommended when operating
this instrument through remote controls using a LAN in a problematic noise environment. For more
information, contact an Iwatsu sales representative or a service center.
2.3.1 Settings for this instrument
From the SYSTEM menu, set REMOTE to “USB”.
2.3.2 Remote/local controls
a. Local mode
In local mode, the instrument is operated by using keys from a panel.
REMOTE icon is off.
This instrument is in local mode when the power is turned on.
There are three ways to return to an instrument that is running in remote mode to local mode.
Restart the power.
Press the LOCAL ([SHIFT]) key.
Close the corresponding COM port on the computer.
b. Remote mode
In remote mode, this instrument is remotely controlled by messages sent through an interface. All
panel keys except for the LOCAL ([SHIFT]]) key become invalid.
The REMOTE icon is ON during the remote period.
This instrument switches to remote mode when the COM port described above has been opened
and a message has been received from a computer.
c. Local lock out mode
This instrument does not support local lock out mode other than for the GPIB interface. When a
lock out operation is necessary, use the GPIB interface.

Item
Setting
TCP/IP port number (connect to)
5198
Delimiter (transmit Note 1)
LF or CR+LF
Delimiter (receive Note 2)
LF or CR+LF
Note 1) This means a computer sends data to this instrument.
Note 2) This means a computer receives data from this instrument.
2.4.3 Connect to network
Before this instrument is connected to a network, a query for information must be sent to the network
administrator. If an incorrect address is specified for the network, unexpected operations may occur
both on the network and in this instrument.
Note) If the computer and this instrument are included in the different networks (i.e. not exist on the
same subnet), it is necessary to set the gateway correctly.
To check the physical connection between this instrument and a computer, perform the following
steps.
1. When a cable has not been connected, set the network connection settings correctly, and
turn OFF the power temporarily
2. Leave the power OFF and connect the cable.
Use a cable to connect to the network terminal such as a hub on this instrument or a
computer. This instrument has an Auto-MDIX function, and either a cross or straight cable
can be used for this connection.
3. Turn ON the power to this instrument.
2.4.4 Check IP connection
A “ping” command from the computer can be used to check connections on the IP network. This
command sends IP packets to the network equipment, and normal status of the IP network is
confirmed when the corresponding response is received.
The “ping” command can be used in a Windows or UNIX environment. In the case of Windows, enter
a command such as the following at the command prompt.
C:¥>ping 10.102.102.102 ()
() The arguments that follow “ping” in this command specify the network equipment whose
connection will be checked, so enter the IP address assigned to this instrument. In this input example,
“10.102.102.102” is used, but this part should be replaced to match the target use environment. Also,
