Infrared (IR) production test verifies hardware functions in multiple ways. You can choose the appropriate production test type according to the specific conditions of the product.
Currently, the following three types are available.
The full verification test of the host covers multiple test items, but serial communication is required. It only applies to the PCBA test solutions.
This test requires a host, such as a personal computer (PC), and an IR transmitter. The operation process is as follows.
Read the MAC address and compare it with the MAC address in the service ticket.
Read the firmware identifier and version number, and compare them with the firmware information in the service ticket.
IR receiving functional test.
IR transmitting functional test.
Signal strength test.
Button test.
IR LED integrity test.
Note: Select the test item for the IR LED integrity, click the button to start the test, and the IR LED will be conductive. You can use a camera to observe whether all the IR LEDs are complete.
The test supports PCBA and finished product test solutions. The device under test does not need to be connected, and you can just enable the IR production test mode. However, the test items only cover the IR receiving and transmitting function.
This test requires a host, such as a personal computer (PC), and an IR transmitter. The operation process is as follows.
If electrical appliances are correctly controlled by the IR receiving and transmitting process, the IR receiving and transmitting function works properly. The test applies to PCBA and finished product test solutions.
You only need to configure an electrical appliance and the adapted IR remote control. Observe whether the electrical appliance responds correctly, in order to check the effectiveness of the receiving and transmitting function. The process is as follows.
Note: If the transmission is successful, the device under test resumes receiving mode.
The flow chart of the finished product test solution is as follows.
