Technical problems of ECAN series products
ECAN-W01S cannot set the STA mode with the official host computer configuration, is there any other host computer configuration, how to enter the STA mode?
It is recommended not to connect to the Wi-Fi of the device first, but use a network cable to connect the device to the computer, change the IP of the computer to 192.168.4.100, and use the upper register to search to enter the configuration interface.
Can ECAN-U01S analyze data from higher level protocols such as CANopen, DeviceNet and J1939?
can be analyzed.
Can ECAN-E01 configure the device through other command formats without using the host computer?
ECAN-E01 can only be configured using the host computer.
Does ECAN-S01 have any requirements for welding? Is it possible to reflow soldering? Is there a limit to the overheating time?
There is no requirement for soldering, please be careful not to solder, and the soldering temperature should be controlled at 200~300°C. Reflow soldering is possible, please refer to the figure below for soldering suggestions.
Can ECAN-E01 send CAN messages via UDP packets from Linux system?
You can use the UDP function to send directly, but the format of the CAN frame to be sent must conform to the protocol. For the protocol format, see the relevant product technical manual.
Can ECAN-U01S diagnose and program the inverter circuit of OPENCAN bus?
ECAN-U01S is a transparent transmission device, theoretically it can send and receive data to the inverter, but it needs actual verification.
Using the ECAN-401 device, assuming that the serial frame sends 15 bytes of data, when converted into a CAN message, as shown in the figure, it needs to be converted into at least two CAN messages, but why the two messages The IDs are all the same?
Sending 15 bytes will be divided into two CAN frames. The frame ID is based on the frame ID set by the device. The two frame IDs will not change, and the data fields are different. When entering the configuration, you need to disconnect the CAN connection first, and at the same time confirm whether the serial port parameters of the device are accurate.
Using the ECAN-401 converter, a Honeywell current sensor sends data in a frame of 10ms, and a frame of 10 bytes, whether the data of the 485 serial port on the other side can be converted in time.
Can be converted in time.
Use the ECAN-401 device to read the extended frame sent by the CAN analyzer through CAN to 485, the frame ID: 00 00 05 01, the data frame: 01, the read message is 81 00 00 05 01 01, and then directly through the serial port Send 81 00 00 05 01 01 to the CAN device, why can't the device be controlled normally? The CAN analyzer shows the ID as 00000000 and the data frame as 81 00 00 05 01 01.
Through the host computer, set the frame type to extended frame, frame ID to 501, and then send mode to transparent transmission mode, check Enable frame ID, enable frame information, save and restart, and then send 01 in hexadecimal through the serial port, and the CAN analyzer will start Can be received on 81 00 00 05 01 01. If the data can be received normally, directly use the transparent transmission mode without checking the frame ID, enable the frame information, and send 81 00 00 05 01 01 directly through the serial port.
The ECAN-401 can be used normally before, but recently ERR always flashes, even if no data is sent, RX keeps flashing. What should I do if I can't connect to the device with the configuration software?

ERR flashes and reports an error, indicating that there is a problem with the baud rate of the CAN bus, or the CAN bus is blocked. It is recommended to confirm whether the serial port baud rate parameter is accurate, and whether the CAN port baud rate matches.
Can two ECAN devices be used for input and output between CAN BUS?
OK. Set the two devices to UDP communication, set both to UDPC, and then fill in the IP address and port of the other party for the target IP. Note that the two devices must be in the same network segment.
