RIGOL Chapter 1 Programming Overview
1-2 M300 Programming Guide
To Build Remote Communication
You can build the remote communication between M300 and PC over USB, LAN, RS232 or GPIB (IEEE-488)
interface.
Operation Steps:
1 Install the Ultra Sigma common PC software
Download the Ultra Sigma common PC software from
www.rigol.com and install it according to the
instructions.
2 Connect the instrument and PC and configure the interface parameters of the instrument
M300 supports USB, LAN, RS232 and GPIB (IEEE-488) communication interfaces, as shown in the
figure below.
Figure 1-1 M300 Communication Interfaces
(1) Use the USB interface:
Connect the USB Device interface at the rear panel of M300 and the USB Host interface of the PC
using a USB cable.
(2) Use the LAN interface:
 Connect the instrument to your PC or the network of your PC using a network cable.
 Check whether your network supports the DHCP or auto IP mode. If not, you need to enable
the manual IP mode, disable the DHCP mode and auto IP mode and acquire the network
interface parameters available (include the IP address, subnet mask, gateway and DNS) from
your network administrator.
 Manually configure the IP address, subnet mask, default gateway, and DNS of the
instrument.
(3) Use the RS232 interface:
 Use the mixed interface convert cable to convert the [RS232/Alarms/Ext Trig] interface
at the rear panel into two 9-pin interfaces, wherein one is a 9-pin male connector used as a
standard RS232 interface, the other is a 9-pin female connector for alarm output and
external trigger signal input, etc.
 Connect the RS232 interface with the PC or data terminal equipment (DTE) using a RS232
USB Device
