1.6 Communication cautions............................................................................................14

1．Preparation before Use
2FRA51602
The FRA51602 can be controlled remotely via USB, GPIB, RS-232, or LAN interfaces.
Program messages can be sent from the controller to achieve the same control of operation as
when using the control panel of the instrument. Response messages received from the
instrument contain measurement values and configuration status.
Connectors for the various interfaces are provided on the back panel of the FRA51602.
1.1 Selection of the remote control interface
USB, GPIB, RS-232, or LAN can be selected as the remote control interface for the FRA51602.
It is not possible to use more than one interface at the same time.
■Displaying the current interface
Press the
_ MENU key and touch the 2/2 [Remote] option on the top level menu to display
the [Remote] dialog box and the interface that is currently set.

1．Preparation before Use
3FRA51602
■Setting the interface
With [Remote] dialog box displayed, move the cursor to [INTERFACE] and press the
_ ENTER to select the communication interface to be used.
< List operation (to set the operation)>
•USB: Communicate by USBTMC
•GPIB: Communicate by GPIB
•RS-232: Communicate by RS-232
•LAN: Communicate by Ethernet
The communication interface can be changed by selecting from the [INTERFACE] menu
and then pressing the [INTERFACE APPLY] function key.

1．Preparation before Use
4FRA51602
1.2 USB overview
1.2.1 Preparation of the controller
To use the USB interface, prepare a controller that is equipped with a USB interface (a
computer to be used for control).
Install a USBTMC driver on the controller. Usually, this driver supports the USB488 subclass
and can perform control over USB that is nearly the same as GPIB.
USBTMC: Universal Serial Bus Test and Measurement Class
That driver is included in the hardware products and software products provided by various
manufacturers that supply the VISA library. If you do not have a VISA library license, it is
necessary to obtain one.
VISA: Virtual Instrument Software Architecture
Using the VISA library enables unified operation over any USB, GPIB, RS-232, or LAN
interface, within the respective supported ranges.
This instrument has been confirmed to operate on the NI-VISA supplied by National
Instruments.

1．Preparation before Use
5FRA51602
1.2.2 Preparation of the FRA51602
The [Remote] dialog box
The information that is displayed when the USB interface has been selected as shown
below.
Vendor ID, product ID, and manufacture number
•Vendor ID Vendor ID = 0x0D4A (hexadecimal notation): a number that
indicates the company
In decimal notation, the number is 3402.
•Product ID Product ID = 0x005D (hexadecimal notation): The product
number for the FRA51602. In decimal notation, the number
is 93.
•Manufacture number Serial Number = 0000000 Example: a 7-digit number that
is specific to the instrument
Message terminator
A set of commands and responses must end with a terminator that indicates the end.
The response message terminator that is sent by the FRA51602 is always LF^EOI.
The terminators used for program messages received by the FRA51602 can be any of
those listed below.
•LF Line Feed code
•LF^EOI LF accompanying an EOI (END message)
・(final code)^EOI EOI (END message) added to the final code
1.2.3 Identification of USB instruments
The FRA51602 is connected directly to the USB connector of the computer by a commercial
USB cable. The instrument may not operate correctly if the connection is made via a USB hub.

1．Preparation before Use
6FRA51602
The FRA51602 is automatically recognized when connected via USB to a computer on which
a USBTMC class driver has been installed. The FRA51602 instruments in a system are
identified by the vendor ID, product ID, and serial number, which are displayed in the [Remote]
dialog box. If the instrument is not automatically recognized, specify those items directly so
that the instrument is recognized.
1.3 GPIB overview
The GPIB interface is not intended for use in an environment with electronic noise .
1.3.1 Preparation of the controller
To use the GPIB interface, install a commercial GPIB interface card on the controller
(computer used for control) and connect the FRA51602 to the connector on the interface card
with a GPIB cable. Refer to the manual for the GPIB interface card for information on driver
software.
1.3.2 Preparation of the FRA51602
The instruments in GPIB systems are identified by addresses that are specific to each
instrument. Set a different GPIB address for each instrument.
[Remote] dialog box
When GPIB is selected, the display is as shown below.
GPIB address
Message terminator
A terminator must be placed at the end of a set of commands and responses.
The response message terminator that is sent by the FRA51602 is always LF^EOI.
The terminators used for program messages received by the FRA51602 can be any of those

1．Preparation before Use
7FRA51602
listed below.
・LF Line Feed code
・LF^EOI LF accompanying an EOI (END message)
・(final code)^EOI EOI (END message) added to the final code
1.3.3 Important points for using GPIB
•Turn off the power to all instruments that are connected to the bus before inserting or
removing the GPIB connector cable.
•When using GPIB, turn on the power to all instruments that are connected to the bus.
•Up to 15 instruments, including the controller, can be connected to a single GPIB bus.
The following limitations apply to the length of cables.
- The total cable length cannot exceed 2 m times the number of instruments or 20 m,
whichever is less.
- The length of one cable cannot exceed 4 m.
•Set a different value for the GPIB address of each instrument. If there instruments on the
bus that have the same address, the instruments may be damaged by output collision.
1.3.4 Basic GPIB specifications

1.4 RS-232 overview
1.4.1 Preparing the controller
To use the RS-232 interface, prepare a controller (computer to be used for control) that is
equipped with an RS-232 serial connector.
Match the parameters listed below on the FRA51602 and the controller.
•Communication speed 4800 to 230400 bps
•Data length 8 bits (*1)
•Stop bit length 1 for sending and 1 for receiving (*1)
•Parity None (*1)
•Flow control None/software/hardware
•Terminator LF/CR LF
*1: This is fixed for the FRA51602. It cannot be changed.
1.4.2 Preparing the FRA51602
[Remote] dialog box
The information shown below is displayed when the RS-232 interface is selected.
Baud rate, flow control, and terminator
Baud rate
This sets the communication speed. The baud rate is the same for both sending and
receiving.
For transmission speeds in excess of 19200 bps, higher speeds require lower cable
capacitance and shorter cable length.

Flow control
This sets the flow control method.
NONE No flow control (default)
SOFT Software flow control
Communication is managed with flow codes (X-ON and X-OFF).
Reliable communication as possible for transmission and receiving,
even with only a ground-only connecting cable. However, binary
data cannot be transmitted and the effective speed may be lower.
In hexadecimal notation, X-ON is 0x11 and X-OFF is 0x13.
HARD Hardware flow control
Communication is managed with a hardware control line (RTS and CTS).
When flow control is enabled, communication is temporarily halted when
the receive buffer is nearly full and resumed when the available buffer
capacity is sufficient.
Terminator
A set of commands and responses must end with a terminator that indicates the end of the
message.
LF The terminator is a one-character LF (Line Feed).
CRLF The terminator is a two-character combination of CR (Carriage Return) and LF.
In hexadecimal notation, CR is 0x0D and LF is 0x0A.
•For FRA51602 sending
The specified terminator is added to the end of the response message.
•For FRA51602 receiving
When the terminator that has been set for this instrument is received, the command is
executed.

1.4.3 Connection
Prepare a commercially-available cable to use for the connecting cable. When connecting to
the serial interface of a personal computer, the cable described below can be used.
Cable specifications: D-Sub, 9-pin, female-female, interlink, with ISO inch screws
To prevent operating problems due to electromagnetic interference
or noise, a shielded cable must be used.
The minimum cable configuration for communication is RxD, TxD, and GND.
For hardware flow control, RTS and CTS are required.
To use hardware flow control, use an interlink cable (Fig. 1-1 (b)). Another cross or reverse
connection method is to connect adjacent pens 7 and 8 (Fig. 1-1 (c)). With that type of cable,
communication is possible, but hardware flow control cannot be used.
