+The One Wire TTL Serial (UART) interface enables daisy chained connection of multiple units.
-This interface operates natively at 3.3V but it is tolerant to 5V or higher voltages making it compatible with virtually all devices operating at TTL level.
+This interface operates natively at 3.3V but it is tolerant to 5V, for interfacing with devices with 5V TTL logic.
 This interface option is directly compatible with Robotis Dynamixel AX, MX series of servos. It can also connect to XL and XM series of servos provided you create a necessary adapter cable or board to connect them.
-It is important to note that this connection uses only 1 wire for DATA, which means a special adapter is required to control the line switching between RX and TX.\\
+It is important to note that this connection uses only 1 wire for DATA, which means a special adapter (or appropriate code for switching TX/RX on and off) is required to control the line switching between RX and TX. The unit already includes the necessary pull-up (10KOhm) on the DATA line.\\
 The most common adapters and connection methods are shown below.
