UART Gateway Protocol
36/47
The UART signals follow the usual conventions:
●
●
●
●
Note that commonly used EIA transceivers invert these logic levels.
Ember supplies the UART Gateway protocol software in two versions: one uses RTCS/CTS
flow control and the other uses XON/XOFF. The UART is set up as follows for these
versions:
●
●
●
●
●
The ASH protocol has been tuned for optimal operation with the two configurations listed
here. These configurations can be changed through manufacturing tokens, but doing so
may result in a degradation of performance. To learn how to change the configuration,
contact your local ST sales representative.
When idle, serial data is high (marking)
The start bit is low (spacing), and the stop bit is high (marking)
Data bits are sent least-significant bit first, with positive (non-inverting) logic
The flow control signals are asserted low
115,200 bps for the RTS/CTS version
57,600 bps for the XON/XOFF version
No parity bit
8 data bits
1 stop bit
