Ethernet LAN TCP/IP Requirements and Setup
Information about Ethernet LAN general requirements, configuration, use, and restoring defaults are discussed in the following sections. Ethernet control programming is discussed with an example in the MG362x1A SCPI programming manuals.

This section is provided for general information about directly manually configuring an Ethernet connection. Consult the user local network administrator for the exact requirements and settings that are required for the network installation.
TCP/IP General Requirements and Settings
Transmission Control Protocol/Internet Protocol (TCP/IP) is a network protocol. TCP/IP is automatically installed and in most cases, installation, configuration, and communication are transparent to the user.
The TCP/IP setup requires the following:
IP Address: Every computer and electronic device in a TCP/IP network requires an IP address. An IP address has four numbers (each between 0 and 255) separated by periods. For example: is a valid IP address.
Subnet Mask: The subnet mask distinguishes the portion of the IP address that is the network ID from the portion that is the station ID. The subnet mask, when applied to the IP address given above, would identify the network ID as 128.111 and the station ID as 122.42. All stations in the same local area network should have the same network ID, but different station IDs.
Default Gateway: A TCP/IP network can have a gateway to communicate beyond the LAN identified by the network ID. A gateway is a computer or electronic device that is connected to two different networks and can move TCP/IP data from one network to the other. A single LAN that is not connected to another LAN requires a default gateway setting of If you have a gateway, then the default gateway would be set to the appropriate value of your gateway.
Ethernet Address: An Ethernet address, or Media Access Control (MAC) address, is a unique 48‑bit value that identifies a network interface card to the rest of the network. Every network card has a unique Ethernet address permanently stored into its memory.
Remote programming and operation between the instrument and remote program is accomplished via a TCP/IP raw socket connection to port 9001. The remote program must establish a TCP/IP raw socket connection at port 9001 of the MS362x1A.
The remote application may connect to the instrument IP address or to its HOSTNAME. If using DHCP instead of a static IP, using the HOSTNAME may be more reliable for finding an instrument on a network.
You may need to contact your network administrator to ensure network security policies, antivirus, and firewall settings do not block access to the controlling computer and its ports.
The MS362x1A can be configured for Dynamic Host Configuration Protocol (DHCP), an Internet protocol that automates the process of setting IP addresses for devices that use TCP/IP, and is the most common method of configuring a device for network use.
To determine if a network is set up for DHCP, connect the instrument to the network and select DHCP protocol. If the network is set up for DHCP, the assigned IP address should be displayed in the network settings.
Network Connection
Interface between the instrument and other devices on the network is via a category five (CAT‑5) interface cable connected to a network. This cable uses four twisted pairs of insulated copper wires terminated into an RJ45 connector. CAT‑5 cabling is capable of supporting frequencies up to 100 MHz and data transfer speeds up to 1 Gbps, which accommodates 1000Base‑T, 100Base‑T, and 10Base‑T networks. CAT‑5 cables are based on the EIA/TIA 568 Commercial Building Telecommunications Wiring Standard developed by the Electronics Industries Association. A pinout diagram is shown in Table: 8‑pin Ethernet RJ45 Connector Pinout Diagram.

Integrated into the RJ45 connector are two LEDs. The amber LED indicates the presence of LAN voltages (a live LAN connection) while the green LED flashes to show that LAN traffic is present. The instrument IP address and its HOSTNAME are set via the System menu (upper left corner) and accessing the ETHERNET or WIFI settings menu.
TCP/IP connectivity requires setting up the parameters described at the beginning of this section. The following is a brief overview of how to set up a general LAN connection on the MG362x1.
You may need to consult your network documentation or network administrator for assistance in configuring your network setup.
1. Access the System menu (three bars in upper left corner).
2. Press; 3-line icon | SETTINGS | ETHERNET displays the network settings as shown in Figure: Network Settings.
3. Change the IP address or Hostname (HOSTNAME SETTINGS).
