We have a system with MD3 and XA2, the XA2 expansion CAN is made wireless using Maknetek transmitter and receiver. No issues for around 10 years service.
Recently upgraded the MD3 to touch screen MD4-5, rest of the system remains identical. We have copied the application file across exactly but are experiencing intermittent drop outs of the wireless bus, resulting in CAN no contact XA2 messages on screen. They are brief and not permanent, only loss for a moment.
The manual for wireless transmitter and receiver states that the bandwidth is limited (understandable) and thus it will miss transmission if too much data is sent. Is there increased CAN traffic on expansion bus when going between 4.07.14.3816 (MD3) and 5.08? The data we are sending and receiving in the software is identical, just wondering if there is more being sent behind the scenes for example module management, diagnostics etc?
We slowed the polling on expansion bus, and this seemed to help, although because its intermittent we wont know for a week or so. Just seeing if it could be a possibility.
