Before using the commands, please read the following:
i
Syntax
-
All commands MUST start with the “$” character or the command will
not be recognized by the unit. Commands must end with a carriage
return (0x0D). Use of a line feed (0x0A) is optional. Commands are not
case-sensitive.
i Parameters
-
The characters “[“ and “”are placed around descriptions of the variable
parameters where additional explanation was needed. Please type
the selected parameter without the contents inside the “[“ and “]”
characters when entering the command.
i
Responses
-
The unit will respond to most commands with a repeat of the
original command followed by the specified parameters or requested
information except where otherwise noted. If an invalid command is
entered the unit will respond with “$err”.
-
All unit responses end with a carriage return (0x0D) + line feed (0x0A).

Only one command may be processed at a time. Additional
commands should not be sent until the response from the previous
command has been received.
