Last year, Moxa discontinued the UPort 1250/1250I and replaced it with the UPort 1250/1250I-G2. This replacement was needed to enhance performance and extend support for industrial applications. The transition reflects Moxa’s commitment to continuous improvement and long-term customer support. Let’s review this replacement nearly a year after the change was made.
Reasons for the Replacement
Moxa made this change to give you the access to better technology. The new Gen 2 models come with improved speed and additional features that make them more suitable for today’s industrial applications. By discontinuing the older models, Moxa can focus on providing long-term support for users. This means better product management and a clear path for continuous updates and technical assistance in the years ahead.
If you’re considering replacing old models, this article will help you understand the differences.
