The
“Series E”, “Series IE” and “Series EM” RS-232 protocol uses carriage returns (‘\r’, ANSI
code 0x0D), but does
not
use line feeds (‘\n’, ANSI code 0x0A). If you are manually typing
commands, some terminal emulator software will automatically feed the line back when you press
enter (and a carriage return is sent) and when the inverter responds (with a response string
followed by a carriage return). However, some terminal emulator software will not do this, and you
will end up with something like the following which is difficult to read:
CMD> setpoint
lvac: 108.0 off
hvac:
132.0 off
nlbatt: 111.0 off
lb
att:
105.0 off
htemp: 45.0 off
lrc: 0.0 off
If this is the case, look for the setting in your terminal emulator software that automatically
appends line feeds after (outgoing or incoming) carriage returns.
When the inverter is
not
in
‘shell mode’, it will
not
echo back characters you type (even though it
is indeed receiving them). To see what you are typing when the inverter is not in
‘shell mode’, turn
on the
‘local echo’ setting on your terminal emulator.
When the inverter
is
in
‘shell mode’, it
will
echo back characters you type. You will want to turn
off the ‘local echo’ setting on your terminal emulator, or you will see doubles of every character as
you type.
*** Always use lower case letters for communication unless noted otherwise.***
COMMANDS
Shell Command
To be able to use the commands below, the inverter must be in
‘shell mode’. To enter ‘shell
mode’, simply type “shell” (without quotation marks) and press enter. If it doesn’t work, you might
have mistyped it, or the inverter may have received some characters before you even started. If
this is the case, just t
ype “shell” again and press enter.
Remember that lower case letters must be used. Upper Case characters are ignored!
When in ‘shell mode’, the inverter will return a command prompt (CMD>) each time you press
enter. Once this command prompt (CMD
>)
appears, the inverter is ready to receive another
command.
