Summary: This article will guide you on how to configure PTP link using TDD/ePTP mode on the ePMP/PTP 550 radios through GUI.
Products: PTP 550 Master and Slave radios.
Difference between TDD and ePTP mode :
ePTP: ePTP mode designed to provide higher throughput and lower latency on PTP links, but GPS sync is not supported in ePTP mode.
TDD : TDD mode has some additional latency but can be synced with PTMP mode radios. (if its a GPS enabled master radio).
Follow the below procedure to carry out this activity:
Configuring the management PC
- Select Properties for the Ethernet port. Go to Control Panel > Network and Internet > Network Connections > Local Area Connection.
- Select Internet Protocol (TCP/IP):
- Click Properties.
- Enter an IP address that is valid for the 169.254.X.X network, avoiding 169.254.0.0 and 169.254.1.1.
- Enter a subnet mask of 255.255.0.0. Leave the default gateway blank.
Connecting to the PC and powering up
- Check that the ODU ETH port is connected to the Ethernet + Power port of the power supply.
- Connect the PC Ethernet port to the LAN port of the PSU using a standard (not crossed) Ethernet cable.
- Apply mains or battery power to the PSU. The green Power LED should illuminate continuously.
- Open a web browser and type: 169.254.1.1
- When prompted, enter admin/admin to login to the GUI and complete the configuration.
Logging into the web interface: Procedure
- Start the web browser from the management PC.
- Type the IP address of the unit into the address bar. The factory default IP address is 169.254.1.1. Press ENTER. The login prompt is displayed:
- Enter Username: admin and Password: admin then click Log In.
Master Mode Configuration
Step 1 – The setup is accessed on the Installation page by clicking the Start Setup button. Under Main tab on Master device, you can configure the device name and SSID. SSID must be same at both ends and different to site name. Click Finish Setup to commit the changes to the device.
Step 2 – Under Radio tab, you can configure Country, Driver mode as TDD PTP, Channel Selection, Channel Bonding and Channel Bandwidth with frequency.
Step 3 – Under Network tab, Device management IP addressing is configured manually in fields IP Address, Subnet Mask, Gateway, Preferred DNS Server, and Alternate DNS Server.
Slave Mode Configuration
Step 1 – Under Main tab on Slave device, you can configure the device name and Radio Mode as Slave.
Step 2 – Under Radio tab, you can configure driver mode as TDD, Preferred Master SSID that defines the Master SSID to which the Slave device will attempt registration, Preferred Master Security Method with pre shared key is to match the pre-shared key configured on the Master for registration with selected frequencies.
Step 3 – Under Network tab, Device management IP addressing is configured manually in fields IP Address, Subnet Mask, Gateway, Preferred DNS Server, and Alternate DNS Server.
Note: Once the link is established then you will be able to see connected Slave devices under Monitor > Wireless option on Master device GUI as shown below:
Wireless Link Test
Go to Tools > Wireless Link Test to conduct a simple test of wireless throughput after link establishment. This allows user to determine the throughput that can be expected on a particular link without having to use external tools.
NOTE: The Wireless throughput is achieved in ideal conditions. It mainly depends on RF parameters and local conditions of the link.
