The available discovery functions are located in the class ScannerConfig: 

Discovering All Scanners – Example 1a

To discover all scanners on a network, use the following function:

Code Block
languagec#
using System.Collections.Generic;
using JoeScan.JCamNet;

namespace Examples
{
    class Program
    {
        static void Main(string[] args)
        {
            List<DiscoveryResponse> responses = ScannerConfig.FindAllScanners();
            foreach (var discoveryResponse in responses)
            {
                System.Console.WriteLine("Base IP Address: {0}, CableId: {1}, Serial Number: {2}", 
                    discoveryResponse.BaseIPAddress,
                    discoveryResponse.CableId,
                    discoveryResponse.SerialNumber );
            }
        }
    }
}

Base IP Address: 192.168.1.105, CableId: 0, Serial Number: 374
Base IP Address: 192.168.1.150, CableId: 0, Serial Number: 1465
Base IP Address: 192.168.1.105, CableId: 22, Serial Number: 1941
Base IP Address: 192.168.1.105, CableId: 28, Serial Number: 1940
Base IP Address: 192.168.1.105, CableId: 30, Serial Number: 1747 
Querying for a specific scanner by CableId or Serial Number – Example 1b

If you want to query for a specific scanner, either by its CableId or serial number, use the following function:

The parameter id is either a CableId or a serial number. Because no hardware with serial numbers below 128 exists, the API assumes any argument < 128 is a CableId, and a serial number otherwise. However, there may be multiple scanners on your network that have the same CableId (and a different IP Base Address). In this case, it is not safe to use this function, as it only returns one DiscoveryResponse and may throw an exception.

...

In the following example, we only want to work with scanners that have a "1" in their network address at the 3rd quad. Use the following function:

 

Code Block
languagec#
using JoeScan.JCamNet;
using System;

namespace Examples
{
    class Program
    {
        static void Main(string[] args)
        {
            ScannerConfig.FindAllScanners(MyDelegate);    
        }

        public static void MyDelegate(DiscoveryResponse response)
        {
            // filter here by your criteria, for instance the subnet: 
            if (response.BaseIPAddress.GetAddressBytes().GetValue(2).ToString() == "1")
            {
                System.Console.WriteLine("Base IP Address: {0}, CableId: {1}, Serial Number: {2}",
                    response.BaseIPAddress, response.CableId, response.SerialNumber);
            }
        }
    }
}
