Run the example

  1. Install and run the device gateway
  2. Download the C# client library
  3. Copy the root certificate of the device gateway to your working directory. As default, the certificate(ca.crt) resides in cert of the installation directory.
  4. The example uses grpc-dotnet. You can change the example/apb/test/test.csproj file as needed.

  5. Change the gateway and the device information in example/apb/test/Program.cs as needed.

     // the path of the root certificate
 private const string GATEWAY_CA_FILE = "../../../../cert/gateway/ca.crt";

 // the address of the gateway
 private const string GATEWAY_ADDR = "192.168.0.2";
 private const int GATEWAY_PORT = 4000;

 // the ip address of the target device
 private const string DEVICE_ADDR = "192.168.0.110";
 private const int DEVICE_PORT = 51211;

  6. Build and run.

     cd example/apb/test
 dotnet run

1. Configure devices

An anti passback zone consists of multiple devices connected by RS485. To run the example, you have to configure two devices as below.

  1. Connect two devices by RS485.
  2. Set one device as a master and the other as a slave. You can configure this setting using the device UI or BioStar 2. Or, you can use RS485 API.

2. Connect to the gateway and the device

The example assumes you use the device gateway. For the master gateway or other connection options, refer to the Connect or ConnectMaster examples.

  GatewayClient gatewayClient = new GatewayClient();
  gatewayClient.Connect(GATEWAY_CA_FILE, GATEWAY_ADDR, GATEWAY_PORT);

  var connectInfo = new ConnectInfo{ IPAddr = DEVICE_ADDR, Port = DEVICE_PORT, UseSSL = USE_SSL };
  uint devID = userTest.connectSvc.Connect(connectInfo);

3. Search and register RS485 slaves

  slaves = rs485Svc.SearchSlave(deviceID);

  registeredSlaves = rs485Svc.GetSlave(deviceID);

  if(registeredSlaves.Count == 0) {
    var slaveArray = new SlaveDeviceInfo[slaves.Count];
    slaves.CopyTo(slaveArray, 0);        
    rs485Svc.SetSlave(deviceID, slaveArray);
  }

4. Make a zone using the master and the slave devices.

  var zone = new ZoneInfo{ 
                  ZoneID = TEST_ZONE_ID, 
                  Name = "Test APB Zone",
                  Type = ApbZone.Type.Hard,
                  ResetDuration = 0, // indefinite
                };

  zone.Members.Add(new Member{ DeviceID = deviceID, ReaderType = ReaderType.Entry });
  zone.Members.Add(new Member{ DeviceID = slaves[0].DeviceID, ReaderType = ReaderType.Exit });

  var relaySignal = new Signal{ Count = 3, OnDuration = 500, OffDuration = 500 }; 
  zone.Actions.Add(new Action.Action{ 
                        DeviceID = deviceID, 
                        Type = ActionType.ActionRelay, 
                        Relay = new RelayAction{ RelayIndex = 0, Signal = relaySignal }
                      });

  apbSvc.Add(deviceID, new ZoneInfo[]{ zone });

  // Test if APB zone works correctly
