3.2.2 Select RS232/485, USB (Serial) or LAN Remote Mode
The serial (RS232/485 & USB) and LAN remote control may be selected even if MODBUS TCP option is
installed. The serial and LAN remote modes are described in the USER MANUAL (IA761-04
-02_).
The MODBUS TCP has similar capabilities as the serial and LAN remote modes, but the MODBUS TCP
programming language is not compatible with the serial or LAN languages (GEN or SCPI).
To select RS232/485, USB or LAN mode:
1. Press the COMM button.
COMM LED illuminates.
INTFC message appears on the Voltage display.
2. Rotate the Current encoder to select the required communication interface.
3. Press the Current encoder to accept parameter.
When the parameter is accepted, the display blinks once.
4. To exit the menu, press the COMM button or the BACK button.
3.2.3 Select MODBUS TCP Remote Mode
Selecting the MODBUS TCP mode allows programming over the Ethernet cable. Any setting and
measurement may be done from a remote computer using the MODBUS TCP communication. Network
configuration settings can be done via built-in web pages.
To select MODBUS TCP mode:
1. Press the COMM button.
COMM LED illuminates.
INTFC message appears on the Voltage display.
2. Rotate the Current encoder to select the
OPT communication interface.
3. Press the Current encoder to accept parameter.
When the parameter is accepted, the display blinks once.
4. To exit the menu, press the COMM button or the BACK button.
NOTE
Refer to USER MANUAL (IA761-04-02_), SYSTem[:COMMunicate]:INTerface <DSC> command
to select MODBUS TCP (OPT) communication interface via communication (via RS232/485, USB or LAN).
