DIP Switch Guidelines
Termination: • Termination must be “on” for devices on each end of the chain.
• Termination must be “off” for devices in the middle of the chain.
• Both termination switches in a pair must be in the same position.
Address:
• Keypad addresses must be assigned starting with “0” and increasing sequentially.
• The physical location of a keypad in the chain has no relationship to its address.
• During initial programming, the KEYBOARD QTY function must be used to enter the
number of keypads in the chain. KEYBOARD QTY can be accessed only through the
keypad whose address is “0.”
