SCM (Serial Configuration Manager)
Description
The Serial Configuration Manager is one of the applications you can use to access the
Configuration Data Space (CDS) settings of the Blue Heat/Net. Since the CDS stores the default
serial port settings, it is important that the line mode is configured prior to first use. Otherwise,
you’ll not be able to access the ports.
Getting Access to the SCM
To access the SCM, you simply connect a serial port terminal device (or a PC running a terminal
emulator program) to any of the serial ports on the Blue Heat/Net, and enter a correct Password.
A command prompt is then sent to the terminal and CDS Parameters can be changed using a
command line style of entry.
NOTE: For RJ-45 models, the Blue Heat/Net ships with
the unit configured to scan all serial ports on the unit for
entry of the Password. This behavior can be changed by
alteration of one of the CDS parameters.
If your Blue Heat/Net model has configurable line interfaces (DB-9 models), certain settings
can affect access to the SCM. The ports are scanned as follows:
The default Line mode setting of all ports is Undefined. Under these conditions, the first two
ports are set to RS-232 mode during port scanning. Access to the SCM is available through these
ports only. (You should set all ports to a known state prior to use).
When a port is set to something other than Undefined, any port with a setting of RS-232 or RS-
485-Full Duplex will be scanned. Otherwise, scanning is not performed, and access to SCM is
not available.
NOTE: To access the Blue Heat/Net via the SCM your
serial line interface settings must be at the default values
of 9600 baud, 8 data bits, no parity and 1 stop bit (9600,
8, n, 1). No flow control is recommended.
In a situation where port scanning is not performed, you can still access the SCM using the push
button reset on the back of the unit. Follow the instructions in the section Activating the Special
Operations Mode and Default Settings to access the SCM in this situation
See the section which describes How the Blue Heat/Net Boots for a complete description of the
Bootup process of the Blue Heat/Net and how to access the SCM.
SCM Command Reference
SCM commands are entered as strings of ASCII characters with options separated by whitespace
characters. The entire command line is terminated by a CR character or CR/LF character pair.
Command lines can be entered manually (via a terminal or a PC with terminal emulator
program) or sent from an application program. There is no character-to-character minimum
timing restriction. The command line buffer is limited to the size of the FIFO on the serial port,
which is 64 characters for the RJ-45 model and 128 for the DB-9 model of the Blue Heat/Net.
If an SCM command is entered with no options specified, the command shows the syntax of its
options and the current setting of those options.
