3.1. UART
XT2500 devices include a 2-wire asynchronous serial interface (UART) operated through RS232 for communication
with a host device. RS232 interface is TIA/EIA-232-F compliant and will accept 0-5V signaling. The UART interface is
a 3.0V TTL interface conforming to the ITU-T V.24 recommendation, with CMOS compatible signal levels (0V for
low data bit or ON state and 3.0V for high data bit or OFF state). If the
l
The default baud rate is 115200 bits/s
l
The default frame format is 8N1 (8 data bits, no parity, 1 stop bit)
l
The interface does not support flow-control
The UART interface is active and requires no authentication by default. AES-128 challenge/response
authentication can be enabled by enabling the console-authentication bit in the firmware flags setting of the
device description.
