Troubleshooting LINK150 ION Protocol Passthrough on Port 7801

[Michael_McSorley]

I am trying to use the ION Pass Through function of the Link150.  Currently, I have a Link150 set to use ION Pass Through port 7801.  I have noticed that after a short time period all communications to devices stops.  When I reboot the Link150 all communications are working properly.  Shortly after the reboot all communications again stops.  For troubleshooting purposes, I removed the Link150 and connected the serial chain to my laptop using a USB converter.  I am able to read data from all meters with no issues using the real-time function in ION Setup.

One thing I have observed when troubleshooting this issue is that port 7801 seems to be opening and closing.  Using the simple 'telnet' command in Windows, I found the port to be open after a reboot.  After a minute the port is again closed.

Has this issue with the 7801 port opening and closing been observed anywhere else?

The new latest firmware (released at the same time as my post!) v 5.29 solves the problem!!  Thanks tech support.
