Operation Setting2-1
The product has two communication system: USB and Optical communications.
Note
For details about the main unit setting, refer to DOEF series Instruction Manual [8-1 Communication Settings].
1. USB communication (-LUs1 option)
This product uses a USB serial converter made by FTDI, and the baud rate setting is required.
The baud rate is selected from 9600 bps, 19200 bps, 38400 bps.
The factory default setting is 9600 bps.
It corresponds to Matsusada Original Command as well as SCPI command.
The USB delimiter is CR.
2. Optical communication (-LGob option)
The baud rate setting is required.
The baud rate is selected from 9600 bps, 19200 bps, 38400 bps.
The UNIT number is selected from 0 to 31.
It corresponds to Matsusada Original Command as well as SCPI command.
The RS-232C delimiter is CR.
After the communication setting, be sure to turn off the power of the product and then, turn it on again to
restart. Changing the setting will be available after restarting it.
If you change the communication setting, be sure to turn off the power of the
product and then, turn it on again to restart. If not, the communication system may
not work properly.
Before connecting the communication cable, be sure to turn off the power off.

DOEF series
As for Optical communication (-LGob option), it is also necessary to configure the connected devices.
The setting is performed by the dip switches on the rear panel.
Set the switch to OFF when Matsusada product CO-G32, CO-RG, CO-HV, and USB-OPT are used to attach
the optical cable connector IN of DOEF series, or when -LGob option is used.
Set the switch to ON when Matsusada product CO-OPT2-25, CO-OPT2-9, or CO-OPT4-25 are used for the
connection.
In DOEF series with -LGob option, if you do not use remote control (to use local
control), be sure to turn off the dip switch. If not, it could cause malfunctions.

・When you do not use the Optical fiber cable connector, be sure to attach the cover to it.
・This product has necessary protection functions, but there is a risk of malfunction if you
use it together with a high voltage power supply in that noise may occur on the AC input
line by the output short circuit in the high voltage power supply. Therefore, you should
have AC input line separately from the high voltage power supply.

2-3) Display of remote control via communication
With the product remote controlled, the LCD present status <LOC> is changed to <REN>.
To change from local control to remote control (on the front panel), issue the “REN” command.
(“#0 REN” command with -LGob option)
In the meantime, as it is changed from local control to remote control, all the setting values will be
initialized. (CV mode, voltage 0 V, Frequency 1 kHz, etc.)
The remote control setting values are not stored in memory.
However, when the unit is returned to the local control from the remote control, the setting values stored
in memory will be recalled.
<LOC> indicates local controlled.
<REN> indicates remote controlled.

2-4) Default value for remote control
As it is changed from local control to remote control with communication, all the settings are reset
to the default value. When changing, the setting values in local control which are stored in
memory will not be used in remote control. In remote control via communication, transfer the
commands to configure settings.
The local control settings are saved in memory, but the remote control settings are not saved.

DOEF series
Checking USB Operation (DC Voltage Output with Original Command of3-1 Matsusada Precision)
This section describes how to check the operation of the product using USB communication after the main
unit settings are completed.
The baud rate setting of USB is required.
Voltage is actually output in checking operation.
Do not connect any load to the product before the following procedure is
completed.
(1) Connect USB cable
Connect the USB cable to a controller (e.g. computer) and the USB connector of the product.
(2) Turn on the power
Turn on the Power ON/OFF switch. (Wait a few seconds for the product startup to complete, or wait until you
get a response from the STS command.)
(3) Enable remote control
Send a command of “REN” from the controller (computer). Then, <REN> will appear on display, and the unit
goes into remote control state.
(4) Output 0 V in CV mode
Send “CV” and “SW1” from the controller (computer).
Then, the voltage 0V is output in CV mode, and “OUTPUT LED” is lit.
(5) Set voltage to output
Send “DCVSET xxxx” from the controller (computer). Enter the value in xxxx within the parameter range. The
DC voltage value set in xxxx will be output.
(6) Stop the output
Send a command of “SW0” from the controller (computer). OUTPUT LED will turn off.
(7) Enable local control
Send a command of “GTL” from the controller (computer). <LOC> appears on display, and the unit goes
into local control state.
(8) Ending the operation
Turn off the POWER ON/OFF switch of the main unit.

Checking Operation of Optical Communication (DC Voltage Output with Original3-2 Command of Matsusada Precision)
This section describes how to check the operation of the product using optical communication after the main
unit settings are completed.
For optical communication, settings of the baud rate and UNIT number are required before communication.
Voltage is actually output in checking operation.
Do not connect any load to the product before the following procedure is
completed.
(1) Connect Optical fiber cable
Connect the Optical fiber cable to a controller (e.g. computer) and the IN connector of the product.
When it is not in use, be sure to cap the connector.
(2) Turn on the power
Turn on the Power ON/OFF switch. (Wait a few seconds for the product startup to complete, or wait until you
get a response from the STS command.)
(3) Enable remote control
Send a command of “#0 REN” from the controller (computer). Then, <REN> will appear on display, and the
unit goes into remote control state.
(4) Output 0 V in CV mode
Send “#0 CV” and “#0 SW1” from the controller (computer).
Then, the voltage 0V is output in CV mode, and “OUTPUT LED” is lit.
(5) Set voltage to output
Send “#0 DCVSET xxxx” from the controller (computer). Enter the value in xxxx within the parameter range.
The DC voltage value set in xxxx will be output. Then, “OUTPUT LED”will turn off.
(6) Stop the output
Send a command of “#0 SW0” from the controller (computer). OUTPUT LED will turn off.
(7) Enable local control
Send a command of “#0 GTL” from the controller (computer). <LOC> appears on display, and the unit goes
into local control state.
(8) Ending the operation
Turn off the POWER ON/OFF switch of the main unit.

DOEF series
Command Syntax4-1
Setting the output voltage of the unit to rated maximum voltage is as follows.
Example: Model at rated voltage 20V
In optical communication, use a space between the UNIT number and command/parameter.
(Communication is possible without a space.)
(1) Input delimiter CR (0DH).
(2) Some commands require a parameter. The parameter values vary depending on the models. (Refer to
“List: Minimum value settings / Return values”.)
(3) Wrong commands are to be ignored.
(4) In optical communication (-LGob option), specify the UNIT number (#0-31). In USB (-LUs1 option), this
is not required as there is no UNIT number in the option.
REN, GTL Commands and Unit Setting4-2There are different settings of Remote control and Local control.
When the product receives “REN” command changing Local control to Remote control, the settings are all
the default value of Remote control.And they are not saved in memory.

Note that it takes about 5 seconds to receive a command because of the initialization
process from the power on. Send the REN command after confirming the startup or the
response from the unit with STS command.
When the product receives GTL command changing Remote control to Local control, the settings are all the
default value of Local control. Each set value of Local control is stored in memory with the previous Local
control state.
Character set of Command4-3Do not use the characters(codes) of section in the followingASCII code table.
Use the LF (0AH) and CR (0DH) only for delimiter.
Command string is not case sensitive.
