Compatibility of Rdv print with Rd8445S

Thank you for the clarification regarding the RDC8445's compatibility with RDV Print. You mentioned that RDV Print isn't supported via Ethernet connection due to the protocol change to TCP/IP (previously UDP), but it should work with USB. However, I've already tested RDV Print with the RDC8445 using USB and Wi-Fi connections, and I'm encountering the same error messages indicating the control card isn't connected or isn't compatible. This contrasts with successful file transfers using RD Works. Notably, I didn't experience issues with the RD-6445S controller. Given my tests and the current unavailability of RD-6445S stock, I'd appreciate further clarification on the following: 1. Specific RDV Print version compatibility: Are there particular versions known to work with RDC8445 via USB? 2. Firmware or settings adjustments: Are there updates or configurations that could enable compatibility? 3. Alternative transfer methods: Besides RD Works, are there other proven methods for reliable file transfer to RDC8445? With this information, I hope to better communicate with my vendor, Meheta CAD Systems, who've indicated support but aren't providing resolutions. If RDV Print isn't viable for critical workflows with the RDC8445, discussing potential alternatives or returns might be necessary. Looking forward to your insights to help address this compatibility challenge.
