4.5.10. Serial port
Controller allows control through UART serial port with TTL 3.3 V logic. UART outputs are located on
. Because of
widespread availability of UART and adapters to USB, Bluetooth, Ethernet and other standard interfaces there is an option for wireless
control (Bluetooth) or control over the internet (Ethernet). UART data protocol is the same as USB data protocol. I.e. it is enough to
enable nonstandard serial port polling in XiLab or in libximc and the device will be found if response delay doesn't exceed two seconds.
It is also possible to control controller with the help of other independently programmed micro-controller, however in this case it will be
required to support
controller communication protocol
.
UART supports the following settings.
Transfer rate 9600-921600 bit/sec
Data bits
8
Parity
enabled or disabled
Parity type
even, odd, space, mark
Stop bits
1 or 2
Note. To connect to the controller via UART one should first connect to it via USB and set required speed, parity and
stop bits and then save settings to non-volatile memory. Standard settings are listed in
, use them if you cannot connect.
Logic type
TTL 3.3V
Maximum data transfer speed 921 kbit
Nominal output current
5 mA

WARNING. High data transfer speeds through long cables in case of electromagnetic interference are impossible. If
transfer errors do occur, use RC filtering circuits and reduce transfer speeds so that characteristic time of an RC-
circuit is at least 4 times less than time needed to transfer a single bit. RC-circuit characteristic time is chosen based
on the circumstances.
