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 Ember support at www.ember.com/support.

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
