We are using the XBP08-DPUIT-024 in combination with XBIB-R-DEV.

we are sending an RS232 signal to the XBIB-R-DEV anf the XBP08-DPUIT-024 transmit it to the other XBP08-DPUIT-024.

as we understand the XBP08-DPUIT-024 is EOL.
can you please suggest a replacement for the XBP08-DPUIT-024 + suitable professional interface board

also the replacement should be able to connect to XBP08-DPUIT-024 as we have more than 300 units running at clients.


There is no replacement for that module. You will need to talk to Digi Sales about what can be done.
