1.1 Serial Command Format
The serial protocol commands are described in the following typographical conventions:
The format of commands is composed of:
• Capital characters - compulsory characters
• Lower case characters - parameters of the command/answer
• Characters in square brackets ([x]) - optional characters
Command terminator characters:
All commands and answers terminate with carriage return (CR) (decimal 13, hexadecimal 0D) or line feed (LF) (decimal 10,
hexadecimal 0A) characters.
A command and answer following the convention above consist of:
Command CMD1<CR><LF>
Answer ANSW12<CR><LF>
NOTE: Terminators are omitted from the remaining examples in the manual.

2.18 STPT - Setpoint Setting
2.19 TATO - Sets activation, target and tolerance
Description Setpoint setting
Note
The transmitted values are valid until the indicator is turned off. To permanently save these values on the RL101, use the
CMDSAV command (see Section 2.22 on page 14).
To save various setpoints, set all of them and at the end transmit the save command (CMDSAV).

x...x
y...y
Setpoint weight values in decimal format with no decimals on up to 6 digits.
If the scale has 3 decimals and the setpoint value is to be set equal 1.000 kg, set xxxx (or yyyy) equal to 1000
NOTE: If setpoint hysteresis is disabled, the off value is ignored but must be less than the on value.
Answer O K
Example
Sets the on value of the 2nd setpoint equal to 2.000 kg and the off value equal to 1.900 kg in a scale calibrated with 3
decimals
Command S T P T 1 0 2 0 0 0 F 1 9 0 0
Answer O K
Description Sets activation, target and tolerance
Note
Only by the tolerance Check mode. The transmitted values are valid until the indicator is turned off. To permanently save these
on the RL101, use the CMDSAV command (see Section 2.22 on page 14).
If the “KKKKK” tolerance is omitted, the “ZZZZZZ” tolerance is considered as both the lower and the upper.

Note
The message is displayed for the interval of time set with the DINT command (Section 2.26 on page 16). When the message in
the command is a numeric type (for example the 00), and the transmitted message has two consecutive points, the message is
stops after the first of the two points.
When the display shows a message transmitted serially with the DISP command, the indicator does not display messages
usually shown in the scale status (ZERO, TARE, HOLD, etc..).
