2.6 Communication Port

The TRRS jack embedded in the controller may be used for connecting to a
computer, Android smart phone, or potential Bluetooth dongle (future product).
The communication standard uses a 0-5V level serial bus. Grin sells a 3m long
TTL->USB adapter cable to connect the unit with the USB port of a standard
computer. This is the same communication cable used with the Cycle Analyst
and Satiator products. Third party USB->Serial cables, such as FTDI's part
number TTL-232R-5V-AJ are also compatible.
A USB-OTG adapter then is needed to connect to an Android smartphone via the
phone's smaller Micro USB or USB-C port.
