J105 pinout: RX1: 4 TX1: 5 RX0: 2 TX0: 3 GND: 8
Terminal sends the following packets periodically (with varying -depending on the traffic from the robot- rate between 10-60ms). I never saw traffic on the TX and RX at the same time (the terminal and the robot seems to be handshaking on the bus).
I currently have the following boards: ESB0019B04 - broken ESB0050D - broken * ESB0100D - likely new
