TReX Jr (DMC02) Firmware version 1.2 (160k trx)
This firmware fixes a bug that affected the 38,400 and 28,800 bps baud rates, and it adds a configuration parameter that lets you optionally insert a 1 ms delay between the last byte of a received command packet and the first byte of the TReX Jr’s transmitted response. Without this delay, slower controllers, such as the Basic Stamp, can miss the first byte of the TReX Jr’s response.
