Troubleshooting Serial Communication for MVI69-MCM Configuration Port

Question:

Hello, I am in the process of transferring configuration settings from one MVI69-MCM unit to another. Unfortunately, I am experiencing difficulties in establishing serial communication with the device through the configuration port. I have tried various cables, including an RJ45 to DB9 adapter, a DB9 to DB9 null modem cable, and a DB9 to USB serial converter cable. Despite setting the baud rate to 57600, I am still unable to establish a connection. I am using the ProSoft Configuration Builder software to upload the configuration, but I am encountering a "timeout" error after the port is successfully opened. I am seeking advice on the correct mode for the processor, optimal serial settings, and ensuring the cable configuration is accurate. Additionally, I am curious if configuration can be done via the backplane using CIP connect or other methods, and if the MVI69-MCM AOI is necessary for the configuration port to work. Could the inclusion of a right end cap terminator be necessary to utilize the configuration port? As someone new to this field, any help or guidance you can offer would be greatly appreciated. Thank you.

Josh98 asked for assistance regarding copying the configuration settings from one MVI69-MCM to another device. Despite using the correct cables (RJ45 to DB9 with a DB9 null modem and a serial to USB converter), establishing serial communication has been unsuccessful. To resolve this issue, ensure that the DB9 to USB cable has the "FTDI" driver installed. Additionally, check the port settings to ensure proper connectivity. By following these steps, you should be able to successfully copy the configuration settings. Best of luck!

It sounds like you’re navigating a pretty frustrating situation! First, double-check the serial settings on both the ProSoft Configuration Builder and the MVI69-MCM; sometimes, it's the small details like parity or stop bits that can throw things off. As for the right end cap terminator, it can definitely affect communication, so it might be worth trying that if you haven’t already. Also, while the AOI isn't strictly required for using the configuration port, having it set up can help ensure you're using the right parameters. Lastly, don’t forget that you might need to configure the processor to be in “boot” mode, which would allow for easier communication. Good luck, and don’t hesitate to reach out for more help!

It sounds like you're dealing with a frustrating situation! First, make sure the MVI69-MCM unit is powered properly and that the configuration mode is set up correctly; some devices need to be in a specific mode to accept configurations over the serial port. Double-check your cable connections and ensure that everything is seated properly. As for the "timeout" error, consider testing the communication settings in ProSoft Configuration Builder—sometimes a mismatch in configuration settings (like parity or data bits) can cause that issue. Regarding the right end cap terminator, it shouldn't be strictly necessary just for the config port, but ensuring proper electrical termination can help with signal integrity. Also, before resorting to the backplane, have you checked the manual for any firmware updates or specific settings for your model? Keep at it, and I hope you find a solution soon!

Frequently Asked Questions (FAQ)

FAQ: 1. What are some common troubleshooting steps for establishing serial communication with the MVI69-MCM unit via the configuration port?

Answer: Answer: Some common troubleshooting steps include checking the cable connections, ensuring the baud rate and other serial settings are correct, verifying the software settings, and confirming the use of compatible cables/adapters.

FAQ: 2. How can I resolve a "timeout" error encountered while using the ProSoft Configuration Builder software to upload configuration settings to the MVI69-MCM unit?

Answer: Answer: To address a "timeout" error, you may need to check if the port is successfully opened, review the serial settings, and ensure that the cable configuration is accurate. Additionally, verifying the compatibility of the software with the device is important.

FAQ: 3. Is it possible to perform configuration settings transfer via the backplane using CIP connect or other methods for the MVI69-MCM unit?

Answer: Answer: While the typical method involves using the configuration port, it's worth exploring alternative methods like CIP connect if the standard approach is not successful. However, the compatibility and functionality of such methods with the MVI69-MCM unit should be confirmed.

FAQ: 4. Do I need to use the MVI69-MCM AOI for the configuration port to work effectively?

Answer: Answer: The MVI69-MCM AOI (Add-On Instruction) may enhance the functionality and compatibility of the configuration port but is not always necessary for basic configuration tasks
