Operation Setting2-1
The product has three communication interfaces: USB, RS-232C, and GPIB communications.
As multiple communications are not allowed to be simultaneously connected, the types of communications and
other settings must be configured.
Note
For details about the main unit setting, refer to DOKF series Instruction Manual [3-14 Communication Settings].
1. USB communication
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. The setting is also common to RS-232C.
It corresponds to Matsusada Original Command as well as SCPI command.
The USB delimiter is CR (fixed).
2. RS-232C communication
The baud rate setting is required.
The baud rate is selected from 9600 bps, 19200 bps, 38400 bps.
It corresponds to Matsusada Original Command as well as SCPI command.
The RS-232C delimiter is CR (fixed).
3. GPIB communication
The GPIB address and terminator (delimiter) settings are required.
For setting, the GPIB address is selected from 0 to 30, and the terminator is selected from EOI/LF/CR..
It corresponds to Matsusada Original Command.
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.
Concerning the three communication interfaces of USB, RS-232C, and GPIB, be
sure to unplug unused communication cables. Otherwise, it could result in
malfunction.

Display of Remote Control via Communication2-2
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.
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.

Default Value for Remote Control2-3 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.
