5.5 RS–232 Commands
Some RS–232 commands require entry of ASCII character strings, integer
values (such as “2400”), and values in engineering notation (such as
“2.00E+02”).
The
↵
symbol at the end of the command represents the carriage return
(CR), which is entered as hex code 0D or, if you’re using a terminal, by
simultaneously pressing the “Control” and “M” keys.
The command should not include a line feed with the carriage return.
Including a line feed adds an extra character and causes the module to
return a “SYNTX ER” response.
The default interface configuration is 9600 baud, eight bits, one stop bit,
no parity.
5.6 RS–232 Command Set
Table 5-2 lists RS–232 commands for the Micro-Ion E module.
UNL Unlock Interface
Functions
In default operating mode, some interface functions are locked. Send the
unlock interface functions (UNL) command to unlock interface functions.
UNL command from host: UNL
↵
Response from module: PROGM OK
↵
If you send the UNL command while interface functions are already
unlocked, the module returns a SYNTX ERR response (see page 26).
