    • NOTE: We tested with the A&D EK-1200i scale with a “Standard Mini Gender Changer”.
  •  
  • Make sure firmware for BlueSnap adapter is up to date. Contact SerialIO support to assist with this. Their support policy can be found here.

• Download yACK BLE from the App Store

How to Set Up the Scale

1. Connect DB9-M6A to scale (with any needed adapters).

• Connect power to DB9-M6A.
• Connect iPad to DB9-M6A through bluetooth.

2. Open yACK BLE. 

• Connect to Nearby BlueSnap DB9. Select after connecting, if necessary.
• Switch to Command mode.
• Send command “set UA B 9600”. This sets the baud rate at 9600bps.
• Turn Scale on.
• Configure scale to baud rate of 9600bps. This should be able to be done by following the manual for the scale. For the A&D EK-1200i, use the following guide and steps:
  • Enter the “Function Setting Mode.”
  • Scroll to the function page called bps.
  • Set bps to 9600bps (parameter #2).
• Go back to weighing mode on scale.
• Put yACK BLE back into Stream mode.
