Installing and Configuring NI-IrDA on RT Targets (RT Module)
IrDA (Infrared Data Association) is a communication standard for transferring data using a wireless infrared connection. Use the IrDA functions to exchange data using IrDA devices.
Complete the following steps to configure an IrDA device on an RT Series controller.
- Install NI-IrDA and NI-Serial RT software on the RT target using NI Measurement & Automation Explorer (MAX). Refer to the Measurement & Automation Explorer Help for information about installing software on an RT target.
- Connect the IrDA device to the built-in RT Series controller serial port.
- Select the RT target in LabVIEW and open the Configure RT IrDA VI located in the National Instruments\NI-IRDA\ConfigureIrDA.llb. The Configure RT IrDA VI automatically downloads to and runs on the RT target.
- Select the appropriate options. The Configure RT IrDA VI includes the following options:
- IrDA Device—Specifies the IrDA device or to disable support for an IrDA device.
- COM Port—Specifies the serial COM port to which the IrDA device is connected.
Note If you use Serial VIs or functions in a VI running on the RT target, you cannot configure the IrDA device to use the same COM port. - Limit Baud Rate to 9600—Limits the IrDA communication baud rate to 9600. Place a checkmark in this checkbox if you have trouble communicating with a faster default communication speed.
- IrDA Device—Specifies the IrDA device or to disable support for an IrDA device.
- Click the OK button.
- Reboot the RT target.
The IrDA device receives the same device name assigned to the RT Series controller in MAX. The IrDA device receives NIirdaxxxx as a device name if you have not configured the RT Series controller in MAX with a device name, where xxxx is a random 4-digit number. The IrDA device name is case-sensitive.
