This routine is used by most computer operating systems. The device then automatically selects an IP address from 169.254.#.# and subnet as described in RFC 3927 (Request for Comments 3927 - Dynamic Configuration of IPv4 Link-Local Addresses). If the Ethernet board does not discover a DHCP server, the MagnaDC power supply will default to the Auto-IP configuration as defined in Table 8.2.
8.1.īy default, DHCP is enabled on the MagnaDC power supply. Open Device Manager and under ports make note of the COM port number, as shown in Fig. Pin outs for these connectors are described in RS232. To test, make a physical connection between the RS232 connector on the MagnaDC power supply and the RS232 connector on the computer. These instructions will validate communications over RS232, but the process can be completed over any interface by adjusting the connection settings. If not already installed, Magna-Power Electronics recommends using the terminal emulation programs called PuTTY for creating serial connections. The validation instructions also provide a common environment for which Magna-Power can reproduce issues in support cases and better serve the customer. The following instructions are intended to help customers isolate problems with computer settings, wiring, and electrical noise.
It is import to establish and validate basic communications functions before starting a sophisticated computer interface project. SL Series MagnaDC power supply purchased with optional LXI TCP/IP Ethernet (+LXI) or IEEE-488 GPIB (+GPIB) interfaces have additional commands and programming instructions.
Refer to Section 5.7, “IVI-COM Driver” for further details. NET, Visual Basic 6.0, LabVIEW, LabWindows/CVI, MATLAB, Measure Foundry, and Agilent VEE Pro. The driver allows the power supply to communicate through many different programming languages and software environments, namely: Visual C++, Visual C#, Visual Basic. In addition, an IVI-COM Driver is included with the installation CD and is available for download from the Magna-Power Electronics web page for more advanced programming requirements.
Standard Commands for Programmable Instrumentation (SCPI) are provided for basic ASCII interfacing without any necessary drivers. There is a variety of methods and interfaces that can be used to program the SL Series MagnaDC power supply from a computer or programmable logic controller.
