9.1 Commands
The AEROCET-380 provides serial commands for accessing stored data and settings. All
commands are terminated by a carriage return. These commands are not case sensitive.
The following table lists the available commands. These commands are available via USB,
RS-485, and WiFi hardware interfaces. The settings (baud rate, parity and stop bits) must
match the computer setting for proper communication regardless of the hardware interface
type.
9.1.1 Computer Mode
Computer Mode is intended for connecting the unit directly to a data logger or computer
program such as Comet. This is the default mode of the unit.
In Computer Mode, all commands are preceded by the <Esc> (ASCII 27) character. No
characters are echoed back to the user when entering commands. All commands are
executed using the <ENTER> key.
Each time the <Esc> key is pressed, the unit will reset to Computer Mode and restart the
command input.
9.1.2 User Mode
User Mode is intended for direct user interaction. In User Mode, all incoming characters are
echoed back to the terminal. The user can wake the unit into User Mode by sending 3 <CR>
(Enter Key) characters within 3 seconds. An asterisk
“*” will be displayed when the unit is in
Terminal Mode.
