At the Bowler’s Keypad 
The Duo system has the option to communicate with the bowler’s keypads either via a wireless interface, or 
alternatively via an extension of the LLAN wired communications cable. Also, you have the option of either one or two 
keypads per lane pair.  
Depending on whether these options, you must set the following settings on the PC Board inside the keypad. 
This will tell the Keypad PCB Board how to behave when a key is pressed.

Wired Keypads 
The advantage of wired keypads is they afford greater reliability, however there is more work to do (and 
therefore expense) at the time of installation. 
For all wired keypads, either single or dual, you must first verify that the jumper for JP2 and JP3 are set to the 
Left. This will activate the communications drivers on the PC Board to send the signal via the LLAN cable. 
Single Wired Keypads 
Remove the battery pack connector and plug in the LLAN cable from the Duo CPU Module into the LLAN IN 
connector on the Keyboard PCB (Printed Circuit Board). 
Then, set the Channel Number on both the Rotary DIP switches to 00. (Zero on the 10’s switch and Zero on 
the 1’s switch) When this is done, the keypad will send out a signal to the Duo CPU module whenever a key is 
pressed, without specifying Odd or Even Lane.
