ADMV96S-WGBE-EK1

60 GHz Wireless Connector

Overview

The ADMV96S-WGBE-EK1 is a complete evaluation and prototyping system for 60 GHz short data links. It consists of a pair of receiver and transmitter boards with a 1 Gbps Ethernet interface on each side of the wireless link.

The 60 GHz wireless link is implemented by the ADMV9525 and ADMV9525 modules. These are coupled with a SerDes device which translates the modules’ SGMII interface to RGMII so that it can be connected to an ADIN1300 industrial low latency and low power 1 Gbps Ethernet PHY. This enables each side of the wireless link to act as an Ethernet port and essentially create a seamless wire-like connection between two ends of an Ethernet cable.

The on-board MAX32650 ultralow power ARM® Cortex®-M4 microcontroller controls the system’s operation and implements the algorithms to configure the wireless link in real time so that optimal link quality is constantly maintained over temperature and various operating conditions. An open-source software stack is provided for firmware development as well as reference applications. The MAX32650 can be programmed and debugged through a JTAG SWD header which can also be used for connecting the Wethlink GUI application to the board.

Application Development

Example 1 – Demonstrate Gigabit Capability by Connecting to the Internet Using LAN with the Contactless 60 GHz Link

Figure 18 ADMV9615 and ADMV9625 Contactless Ethernet Link Labeled Pair1 and Pair-2

Hardware Connections

Figure 19 Hardware Connections for Example 1

1. Mount the ADMV9615 and ADMV9625 Assemblies onto the guide rails with patch antennas facing each other.

2. Connect 12V power supplies.

3. Connect one RJ45 Ethernet connector to your PC.

4. Connect the other RJ45 Ethernet connector to your Local Area Network.

5. Turn off your PC’s Wi-Fi connection.

6. Within a few seconds, your PC should connect to your LAN with a speed of up to 1 Gbps (if your network can support it)

7. (Optional) Connect MAXDAP connector using a micro-USB to your PCs if you would like to configure the firmware.

Example 2 – Create a Two PC LAN Connected with the Contactless 60GHz Link and Share Large Data Files

Figure 20 ADMV9615 and ADMV9625 Contactless Ethernet Link Labeled Pair-1 and Pair-2

Hardware Connections

Figure 21 Hardware Connections for Example 2

1. Mount the ADMV9615 and ADMV9625 assemblies onto the guide rails with patch antennas facing each other.

2. Connect 12V power supply, 2 PL.

3. Connect one RJ45 Ethernet connector to PC1’s Ethernet jack.

4. Connect the other RJ45 Ethernet connector to PC2’s Ethernet jack.

File Sharing Setup

The following procedure was taken from: How to Share Files between Two Computers Using LAN Cable – TechWiser

• On PC1, go to the Start menu and search “Control Panel”. Once you see it, click on it, to open it.

Figure 22 File Sharing Setup

• Choose Networks and Internet.

• Next, choose Network and Sharing Center.

• Click on Advanced Sharing Settings.

• Choose All Networks.

• Choose Turn on Sharing.

• Turn off Password Protection (Once Done with File Sharing Turn Password Protection Back On)

• Perform steps 2 through 6 for PC2.

To put both PCs on the same network, manually set up IP settings by opening Control Panel.

• Choose Network and Sharing.

• Select Ethernet and click Properties.

• Select Internet Protocol Version 4 (TCP/IPv4).

• Select Properties.

For PC1, choose “Use the following IP address”.

• IP Address: 192.168.1.1

• Subnet mask: 255.255.255.0

• Default Gateway: 192.168.1.2

Use the following DNS server address:

• Preferred DNS Server: 208.67.222.222

• Alternate DNS server: 208.67.220.220

For PC2, choose “Use the following IP address”.

• IP Address: 192.168.1.2.

• Subnet mask: 255.255.255.0.

• Default Gateway: 192.168.1.1.

Use the following DNS server addresses:

• Preferred DNS Server: 208.67.222.222

• Alternate DNS Server: 208.67.220.220

• Open Windows Explorer and click on the Network tab.

• If everything is set up properly, both computers should appear.

• You still need to share a target folder on the LAN.

• Create a new folder on the desktop and place some large files into it.

• Select the folder you want to share and right-click it.

• Choose Everyone and click Add.

• Once shared, the next window will show the location of the folder.

• That’s it! Go back to the PC from which you want to access the file, open the Networks panel, and click on the other computer’s name.

• Here you will see the folder you just shared. Open the folder and transfer files and folders as you normally do—copy and paste, etc.

• You can repeat these steps from the other computer as well.

Example 3 – Use Iperf to Check Ethernet Link Speed
