Appendix A Code Examples

A.1 Request List of Devices

To request a list of devices:

1. Create an MTSCRANET.MTSCRA object.

2. Set the connection type with setConnectionType().

3. Add a handler for OnDeviceList().

4. Call requestDeviceList().

MTSCRANET.MTSCRA listMTSCRA = new MTSCRANET.MTSCRA(); 
listMTSCRA.setConnectionType(MTConnectionType.USB); 
listMTSCRA.OnDeviceList() += listMTSCRA_OnDeviceList; 
listMTSCRA.requestDeviceList(MTConnectionType.USB); 

listMTSCRA_OnDeviceList( 
object sender, 
MTConnectionType connectionType, 
List<MTDeviceInformation> deviceList) 
{ 
//Handle deviceList 
}

A.2 Open Device(s)

To open multiple devices:

1. Create an MTSCRANET.MTSCRA object.

2. Set the connection type with setConnectionType().

3. Add a handler for OnDeviceList().

4. Call requestDeviceList().

5. Create an MTSCRANET.MTSCRA object for each reader.

6. Set the connection type with setConnectionType() for each reader.

7. Call openDevice() for each reader.

MTSCRANET.MTSCRA listMTSCRA = new MTSCRANET.MTSCRA();  
listMTSCRA.setConnectionType(MTConnectionType.USB); 
listMTSCRA.OnDeviceList() += listMTSCRA_OnDeviceList; 
MTDeviceInformation listDeviceInfo; 
listMTSCRA.requestDeviceList(MTConnectionType.USB); 

listMTSCRA_OnDeviceList( 
object sender, 
MTConnectionType connectionType, 
List<MTDeviceInformation> deviceList) 
{ 
    //Handle deviceList 
    For Each (dev in deviceList) 
    { 
    
    } 
    listDeviceInfo.Add(dev) 
} 
MTSCRANET.MTSCRA msr1 = new MTSCRANET.MTSCRA(); 
MTSCRANET.MTSCRA msr2 = new MTSCRANET.MTSCRA(); 
MTSCRANET.MTSCRA msr3 = new MTSCRANET.MTSCRA(); 

msr1.setConnectionType(MTConnectionType.USB); 
msr1.setAddress(dev.Address); msr1.openDevice(); 
if (! msr1.isDeviceConnected()) 
{ 
    msr1.openDevice(); 
} 

msr2.setConnectionType(MTConnectionType.USB); 
msr2.setAddress(dev.Address); 
msr2.openDevice(); 
if (! msr2.isDeviceConnected()) 
{ 
    msr2.openDevice(); 
    } 
    
msr3.setConnectionType(MTConnectionType.USB); 
msr3.setAddress(dev.Address); 
msr3.openDevice(); 
if (! msr3.isDeviceConnected()) 
{ 
    msr3.openDevice(); 
}

Close Device

if (mMTSCRA != null) 
{ 
    mMTSCRA.closeDevice(); 
}

Get Connection Status of Device

if (! mMTSCRA.isDeviceConnected()) 
{ 

}

Receiving Card Data from Device

if (! mMTSCRA.isDeviceConnected()) 
{ 
mMTSCRA.CardDataReceived += OnCardDataReceived; 
mMTSCRA.openDevice(); 
} 

public void OnCardDataReceived(Object sender) 
{ // Display last 4 digits of the card 
CardLast4.Text = mMTSCRA.getCardLast4(); 
}

A.6 Send Command to Device

if (mMTSCRA.isDeviceConnected()) 
{ 
    // Send discovery command 
    mMTSCRA.sendCommandToDevice(“C10206C20503840900”, 0); 
}
