Move any programming questions to that thread.

Just a quick note on the programming protocol for your chair ..... I'm unsure if it is CANBUS communication for programming or the much easier Serial type communication which is just RX and TX.
Perhaps one of the denizens here knows for sure.

There is a pic of a really cheap RX TX setup in the Q logic thread using a CH340 USB - Serial adaptor
The standard specifies a maximum open-circuit voltage of 25 volts: signal levels of ±5 V, ±10 V, ±12 V, and ±15 V are all commonly seen depending on the voltages available to the line driver circuit. Some RS-232 driver chips have inbuilt circuitry to produce the required voltages from a 3 or 5 volt supply. RS-232 drivers and receivers must be able to withstand indefinite short circuit to ground or to any voltage level up to ±25 volts. The slew rate, or how fast the signal changes between levels, is also controlled.
Because the voltage levels are higher than logic levels typically used by integrated circuits, special intervening driver circuits are required to translate logic levels. These also protect the device's internal circuitry from short circuits or transients that may appear on the RS-232 interface, and provide sufficient current to comply with the slew rate requirements for data transmission.

Download for what?
