I am in need of a modem like this one. After searching I found that this specific model is no longer available. I am needing one to take place of this one, I use it to send messages to our Marquee sign. Can you help me find one that would work?
These devices went EOL in 2012.
There is no direct replacement but there is a reference to a migration guide that can be found at https://www.digi.com/pdf/appnote_migration-guide_9xstream-xsc.pdf
However these devices are also NRND and significant redesign is required to use them. I would suggest you replace both radios in your application with newer devices. You likely would also need to make software changes to your system in order to integrate newer radios.
