The INLINE® 8 adapter is a no nonsense, do everything diagnostic interface built for shops that don’t have time to fight their tools. Plug in via USB when you want rock solid stability, or go wireless with Wi Fi or Bluetooth when you want freedom to move around the bay without tripping over cables. Either way, you’re connected fast and you’re working immediately.
Built to meet TMC RP1210 and RP1227 standards, INLINE® 8 plays nice with Cummins, OEM, and third party diagnostic and service software, so you’re not locked into a single ecosystem. It handles high speed communication with support for 250K, 500K, and up to 1Mb per second baud rates, which means faster reads, quicker commands, and less waiting around staring at a loading bar.
This adapter is ready for what’s next too, with Diagnostic over Internet Protocol support baked in. From legacy systems to modern CAN and beyond, INLINE® 8 covers a massive range of protocols including J1708, J1587, J1939, ISO15765, ISO9141, ISO14230, KWP2000, and CAT Data Link.
Dual band Wi Fi and Bluetooth 5.1 give you reliable wireless performance in real world shop conditions, not just on a spec sheet. If you want one adapter that just works across trucks, software, and workflows, INLINE® 8 is the workhorse you keep plugged in every day.
