Rice Lake CLS-420 Cargo Lift Scale - Bluetooth Option - Manual (Page 4)

4 Bluetooth Option Installation Instructions
Using the Bluetooth Option
The Bluetooth option operates as a simple serial to Bluetooth converter, using the Bluetooth SPP, or Serial Port
Protocol.
The device is set up to be discoverable at all times.
1. From a PC or other Bluetooth device, perform a search for available Bluetooth devices.
• The Bluetooth Option should show in the search results with its MAC address, and/or
• the name “RLWS-xxxxxx”, where xxxxxx is the last 6 digits of the MAC address.
2. To pair to the Bluetooth Option, select it from your search results (or enter its name / MAC address).
• If your device supports SSP, or Simple Secure Pairing, the devices should pair on their own.
• If you have trouble pairing in this way, or your device/program asks for a pairing key, enter the default
key “1234”.
3. Once paired, the Bluetooth Option should show as a serial communications port on your device. At this
point, you can use your software to connect to the Bluetooth Option’s serial port and communicate with the
scale indicator.
Note The serial port in your indicator that is connected to the 109266 board J1 (Port 1) must be set for 19200 baud,
8 bits, no parity, and 1 stop bit. J2 on the 109266 board is not used with the Bluetooth Option.
