Introduction

This manual describes the available serial protocol commands for the RL101 below-the-hook scale. The RL101 scale is a lift and weighs device, refer to Safety and Periodic Maintenance Manual (PN 153105) for more information. Manuals are available from Rice Lake Weighing Systems at www.ricelake.com/manuals Warranty information is available at www.ricelake.com/warranties

Serial Command Format
The serial protocol commands are described in the following typographical conventions:

Example

|
---|---
Command| C| M| D| 1| Example of a specific command
Answer| A| N| S| W| 1| 2| Answer to the specific command

The format of commands is composed of

• Capital characters – compulsory characters
• Lowercase 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 consists of

Command

STPT – 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).

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.
