Setup Commands
The defaults for the Set Baud and Set Echo Mode
commands are configured in Composer via the Unit
Properties dialog. Settings made via these Control Protocol
commands will be overridden by the values in the last
pushed Site File on the next hardware reboot or push. To
establish the permanent state, right-click on each unit and
select Unit Properties, then click Configure Remote Control
Port(s). Settings may be set independently for the Ethernet
and RS-232 ports.
Note: If you ever find yourself in a situation where you
are not sure of the RS-232 port settings, you can use
Composer to return the unit to default values. Simply open
the Hardware->Upgrade Firmware/Hardware Settings dialog
and click on the Erase Memory button. You can then select
to erase the Accessory Port Settings. Doing this will set
the baud rate, echo mode and quiet mode settings to the
factory default values.
Alternatively, the rear panel reset button can be used to
return the settings to factory defaults. However, that should
be only used as a last resort since it also resets many other
settings.
(SB) Set Baud
The Set Baud command controls the RS-232 port’s baud
rate.
The syntax of the command is:
SB <BAUD><CR>
Where <BAUD> is 1200, 2400, 4800, 9600, 19200, 38400,
57600, or 115200.
If the command is accepted, the unit will respond with the
string:
ACK<CR>
If the command is interpreted but fails for any reason the unit
will respond with the string:
NAK<CR>
The baud rate is saved in non-volatile memory so it is
retained across power cycles. This command can be sent
to either the Ethernet or RS-232 port, but only affects the
RS-232 port.
Note: New units default to a baud rate of 57600.
(SQ) Set Quiet Mode
The Set Quiet Mode command controls the text output
of the control port during responses. When quiet mode is
turned on, it restricts the output to just ACK, NAK or simple
values. All command descriptions above assume that quiet
mode is turned ON. Quiet mode ON should generally be
used for normal operation.
When quiet mode is set to OFF, lengthy strings intended to
be read by humans are sent in response to commands. This
mode is useful when using a terminal program for testing or
debugging.
The syntax of the command is:
SQ <ON/OFF><CR>
Where <ON/OFF> is 0 = OFF, 1 = ON.
If the “SQ 0” command is accepted, the unit will respond
with the string:
Setting Quiet Mode to false.<CR>
If the command is interpreted but fails for any reason the unit
will respond with the string:
NAK<CR>
The quiet mode state is kept separately for the Ethernet port
and the RS-232 port. A Set Quiet Mode command received
on the Ethernet port does not affect the RS-232 port and
vice versa. The quiet mode state is saved in non-volatile
memory, so it is retained across power cycles.
Note: New units default to quiet mode ON.
(EH) Set Echo Mode
The Set Echo Mode command controls the text output of
the control port during commands. When echo mode is
turned on, all characters that are received on the RS-232 or
Ethernet port are sent or “echoed” back. This mode is useful
when using a terminal program for testing or debugging.
When echo mode is turned off, the characters received are
not echoed back. All command descriptions above assume
that echo mode is turned off. Echo mode OFF should
generally be used for normal operation.
The syntax of the command is:
EH <ON/OFF><CR>
Where <ON/OFF> is 0 = OFF, 1 = ON.
If the command is accepted, the unit will respond with the
string:
ACK<CR>
If the command is interpreted but fails for any reason the unit
will respond with the string:
NAK<CR>
The echo mode state is kept separately for the Ethernet port
and the RS-232 port. A Set Echo Mode command received
on the Ethernet port does not affect the RS-232 port and
vice versa. The echo mode state is saved in non-volatile
memory so it is retained across power cycles.
Note: New units default with echo mode OFF.
