Please see “How to reset the preh keyboards” on page 7 and test. 

 

 

3.1 Data transmission conflict between keyboard and Scanner. 
There might be more than one solution for this problem.  
Solution1: The keyboard output speed and the scanner output speed is causing 

conflicts when transmitting the data. Please change the output speed of the 

keyboard by following “How to change the output speed of the keyboard” on page 
9. After, please re-test. 

 

Solution 2: The keyboard-scanner configuration might be causing a problem. 

There is no standard on the output speed for scanners, so if you connect the 

keyboard and the scanner through a “Y” cable to the computer, the keyboard 
output will appear to be slowed down or the computer might not detect it. Please 

connect the keyboard directly to the computer. Then connect the scanner 

through the daisy chain port of the keyboard. The daisy chain port might be 

located on the side or the back of the keyboard.
