Server Manager

Note: You must start the service!

 

Use the Server Manager (SDRServerManager.exe) to configure the server (SDRServerService.exe) which runs as a Windows service. Start the Server Manager from either the Windows Start menu or the Tools pane of the Console's ribbon bar.

Before starting the service you must:

  • Define at least one account,
  • Add at least one radio definition,
  • Check the network definition.

Accounts

The account definition is very basic, at least one account is required otherwise there will be no logins!

Radio Definitions

Select radios just as you do in the console.

Firewall

The Firewall definitions are optional, you can also control access using your routers although configuring a router can be rather slow. Each firewall definition is an IPV4 dotted address added to either the Allow (whitelist) or Block (blacklist). Remeber to check Enable to apply the Firewall definitions.

When enabled, the logic is:

  1. If the address is in the Block (blacklist) the connection is rejected.
  2. If there are no entries in the Allow (whitelist) the connection is accepted.
  3. If the address is in the Allow (whitelist) it is accepted.
  4. If the address is not in the Allow (whitelist) it is rejected.

Network

Incoming Connections

Select the address to listen on - usually any address is OK, but you can restrict the address to a specific network adapter, for example a wired connection. The default port is 50101. If the Windows firewall is enabled you must ensure the port is added to the list of open ports in the Inbound rules, the protocol used is TCP.

Bandwidth

There are seperate settings for LAN (your local network) and WAN (the outside network).

Compression: reduce the bandwidth by using both Huffman code and a clever idea by Youssef Touil (Airspy, SDR#) to ensure no more than 16 bits are required to send each 32-bit sample.

Max bandwidth: restrict the maximum bandwidth, the actual bandwidth will be less than this. When you select a Max bandwidth a corresponsing value in bits is updated.

If compression is enabled the calculation is 18 bits per sample (16 bits per sample + 2 bits for TCP overhead). If compression is not enabled the calculation is 34 bits per sample (32 bits per sample + 2 bits for TCP overhead).

Hint: monitor the current bandwidth in the Connections window.

Service

Install will:

  • Add the Windows service SDR-Radio.com V3 Server,
  • Set the service to automatically restart if it ends unexpectedly,
  • Set the service to start when your system starts,
  • Start the service using the local system account (this is a predefined system account). Many Windows services use this account, with Windows 10 you use the task Manager to display services.
