In the push of everyone, when the two-channel equipment line did not pass, it is recommended that everyone will self-test equipment. Due to the limited space, there is no specific self-test operation method. A case I met today, explains how our GCAN-202 equipment is self-test.
Case restore
Today, I received a telephone number from a scientific company from Shandong. The company left a colleague to handle the next our GCAN-202 equipment. Now Wang Gong does not know the IP address of this device, etc., causing him to connect The GCAN-202 device is therefore no way to determine if the device is corrupted.
It is still a lot of users who have just worked properly when they have just got the equipment, but because the GCAN-202 devices have two separate CAN communication interfaces, therefore, when the user does not have other devices to cooperate with debugging It can be self-test by connecting the two CAN channels of the GCAN-202 device together, and then use two channels to transmit and receive data, it is determined whether or not the device function is normal. Specific steps are as follows:
first step
Connect the GCAN-202 device to the computer, connect the DC24V power supply, at which point the device's POWER light is on, the SYS light is flashing. And connect the CAN H and CAN L of the CAN1 to CAN H and CAN Ls in the CAN2 channel, and all the DIN interfaces between the two CAN interfaces are all dial ON.
Second step
GCAN-202 hardware factory default IP: 192.168.1.10, if you don't remember the IP address of the device like Wang, you can restore the factory settings by pressing the device on the reset button by electricity the device. (Click the picture to view the big picture)
After the GCAN-202 is powered on, find the reset button as shown in the device, press the button for about 5-6 seconds, to wait for the LAN indicator to CAN1, the CAN2 indicator alternately flicker, indicating that the system parameters have been reset, loosen After the button, the GCAN-202 is re-powered, and the system will return to the factory settings.
third step
Open the two network debug assistants after connecting the GCAN-202 to the computer (note the IP address of the computer to be in the same network segment with the IP address of the GCAN-202), select the protocol type to TCP Client, the local host address is the PC IP address, The remote host address is set to 192.168.1.10.4001 and 192.168.1.10.4002, click the connection.
Send an example
Check 16 credit display and 16 credit transmission, in the network debug assistant 1 Send area input 08 00 00 00 00 01 11 22 33 44 55 66 77 88, click Send, see if another network debug assistant 2 is successful, reverse 2 issued 1. If the transceiver is successful, the GCAN-202 device CAN1 and CAN2 indicator status are blinking when the data is passed. At this point, the device can prove that it is functional.
Case results
After guiding the princes, it is found that the two network debug assistants have corresponding data received, so it can be judged that the GCAN-202 device in the king's hand is easy to use, saving time to send back time.
Zhou Mong Message:
When you just get the device, you can self-test according to the type of different devices, the self-test process is equivalent to testing its function, allowing engineers who are not familiar with the product to quickly, or by self-test operation, exclude The equipment itself is faulty, saving debugging time. , Read the full text, description: Ethernet transfer CAN equipment (GCAN-202) Self-testing process example
