Dear Wizards, I am attempting to update the firmware on this small HMI using a USB to serial converter from Automation Direct, specifically the blue model. I have configured the COM port and assigned it based on the guidance provided in the programming software's documentation. However, I am encountering difficulties as the HMI is not being detected, with an error code 2 and command 18 being displayed. Any insights or suggestions would be greatly valued. Enjoy your Friday.
User Rsflipflop256 is seeking assistance with flashing an HMI using a USB to serial converter from Automation Direct. Despite setting up the COM port as per the programming software's documentation, an error code 2, command 18 is displayed, preventing recognition of the HMI. Further details are needed to provide insights. Which specific cable from Automation Direct is being utilized - a USB to RS232 converter? Please provide the exact error code text and details of when and where it appears. Additionally, have you attempted using a null modem since there seems to be no pinout available for the serial port on the panel? Any additional information would be helpful. Happy Friday!
I recently replaced the original AD EA-MG-PGM-CBL with an Amazon cable, but encountered the same error message: "Incorrect communication packet (Time-out error)." To troubleshoot, I checked the cable, comms port, and port assignment on the panel. However, I do not have access to a null modem. After researching, I found that the cable is USB and from the brand NXT Technologies. Despite trying both cables and rearranging com ports, I am still stuck with the same error. Unsure of what steps to take next, the error code is 2 and the command is 18.
In a forum post, Rsflipflop256 shared their experience with an AD cable error, trying both an Amazon cable and an NXT Technologies brand without success. The error message displayed was "Incorrect communication packet (Time-out error)," prompting them to troubleshoot the cable, comms port, and panel assignment. They also mentioned struggling with error code 2 and command 18, unsure about the quality of the AD cable. To address the issue, Rsflipflop256 recommended a reliable converter like the Tripp-Lite USA-19HS and emphasized the importance of a null modem for proper communication. They also discussed the possibility of counterfeit chips in prolific drivers used by the EA-MG-PGM-CBL, cautioning against cheap, unreliable products. Overall, they advised sticking with reputable brands to avoid compatibility issues commonly seen with counterfeit adapters on the market.
How to connect an AD adapter to an HMI with 2 serial ports, a db9, and db15? There is no RJ12 port for the AD adapter's correct pinout. It is recommended to use breakout boards to create a custom cable for accurate connection.
If you are experiencing communication errors, it is important to ensure that you are using the correct EZ-PGMCBL cable and not a standard RS-232 cable. You can purchase an EZ-PGMCBL or create one on site using the wiring diagram provided in Appendix A. Verify the cable's integrity by checking for continuity. To troubleshoot further, refer to Appendix B to determine if there is a software/firmware incompatibility. Check the port selection on the EZTouchPanel by pressing the upper and lower left corners simultaneously, selecting COM1 as the computer port, and ensuring it is reporting as such. If not, adjust the settings using the EZTouch software. It appears that the necessary diagram is included in the document's appendix. You have the option to purchase the recommended adapter or create one to loop DTR, DSR, and CTS back to the adapter for successful communication with the software.
Hey there! I've encountered a similar issue before. Try verifying whether you're using the correct driver for the particular USB to Serial converter. Sometimes, a mismatch between the driver version and the device can cause issues. Furthermore, double-check the assigned COM port - make sure it's not being used by another device. You might also want to test your converter and USB port with another device, if possible, to rule out any hardware issues. Hope that helps and have a great Friday!
