Black Box TL115A 2PT RS232 Passive Splitter

Keep serial connectivity simple when one RS232 DCE device must serve two RS232 DTE endpoints. The Black Box TL115A passive splitter is built for straightforward port sharing, letting you combine two 9-pin DTE ports into one 9-pin DCE port without external power or configuration. That makes it a clean fit for environments where uptime matters more than complexity. Because it is passive and port powered, the splitter avoids the failure points that come with powered conversion gear. There is no software to load, no settings to tune, and no power adapter to manage. Install it quickly for a temporary test bench, or leave it in place for a permanent serial connection where reliability and simplicity are the priority. For infrastructure teams maintaining legacy serial equipment, the TL115A helps preserve existing workflows while reducing cable clutter and setup time. It is a practical accessory when you need to extend the life of RS232 devices without introducing unnecessary hardware into the path.
