In both formats, ID is the Processor’s serial number, which can be found on the serial
number plate on the rear panel (ignore leading 0s), or in the Factory page of the LCD
front panel. The Factory page can be displayed by poking a small screwdriver or a paper
clip once into the small hole on the bottom-left corner of the keypad. The Command is
a text command string (7-bit ASCII characters only). is the carriage return char-
acter (ASCII value 13). Each command requires a carriage return at the end of the line.
We will not show this in the examples.
The second format requires two extra bytes. The first byte is 0xFE (254 in decimal) and
is the only 8th-bit-set number accepted by the Model D-3. The second extra byte is the
check-sum byte that is the lower 7 bits of the 8-bit sum of all the bytes from 0xFE to
, inclusive.
The two formats may be mixed. Whenever 0xFE is detected, the D-3 automatically
switches to the extended format. When an extended format packet is sent, the reply is
also in the extended format. All white spaces and tab characters are automatically re-
moved before parsing and command strings can be in either upper or lower cases. The
following characters result in the same command:
1NE3,1
1 Ne 3, 1
1n E3, 1
The Model D-3 replies to every serial command. The format of the reply echoes the
command. For example, if 1NE3,1 is sent from the user, the reply from the D-3 when
the command is successfully executed is: 1NE3,1
If 1NE3, is sent from the user, the reply is 1NE Syntax error, indicating a syntax error
in the command (parameter value missing).
