ASCII PROTOCOL
The RS485 serial port can be configured for ASCII protocol, which is intended for applications that don’t require custom
software on the host side. Off the shelf terminal emulation software can be used to receive messages from the device.
Percent LEL and sensor readings are sent once per second and user prompt messages are sent during the calibration
process to guide the user at each step. Default serial settings are 9600 baud, 1 stop bit, and no parity. Protocol and
serial parameters should be selected with the HART handheld communicator.
