KX series v.1.70
The K-radio keypad has a 32 device radio receiver. It connects to the control unit the through bus 485 line. A maximum of 2 can be
connected to the control unit, therefore each keypad with a radio receiver will take a spot in the total number.
Important: address the keypads with receivers always at the first two spots.
K-radio rear view
On the back of the keypad there are two pairs of dipswitches with 2 selectors:
- keyboard address = the address tied only to the keypad function
- HW address = address tied only to the radio receiver section
The other dipswitches on the board are to be left in the OFF position. Even the LED indications don't need to be
checked. All of the indications for the device operation are visible on the keypad.
note: To enable anti-opening protection, open the jumper on the back of the board
The control unit has 4/8 inputs, which can be expanded by using the optional Expin module.
The module must be connected to the BUS-485 line with the respective terminals A, B, +12V and -.
Before providing power to the system, in order to differentiate the peripherals, you must address them using their microswitches
(DIP-SWITCHES), referring to the following figure.
