Preface The LCD 64x32 logic boards are used for mounting LCD 64x32 SmartSwitches or SmartDisplays into panels and system assemblies. The 2 switch versions are also used in the SmartSwitch Dev Kits as demonstration platforms for the SmartSwitch and SmartDisplays. This user manual will go through general features. The NKK Switches’ SmartSwitch web site is http://www.nkksmartswitch.com/. 2. General Logic Control Features The LCD 64x32 logic boards are PCB’s that have mount positions for one or more LCD 64x32 SmartSwitches or SmartDiplays. The switches/displays can be mounted directly on the logic board or on a socket mounted on the board. One or two switch boards are the most common but logic boards with other configurations are available as well as custom designs. They have some “glue logic” for converting the select lines and switch scanning to serial, and therefore many logic boards can be daisy-chained via 14-pin ribbon cables. The switch numbering is according to their order in the daisy-chain, where the switch number one is on the logic board connected directly to the controller. There are three types of LCD 64x32 logic boards; RGB pushbutton, RGB display, and RGB compact. 3. Part Number Configuration The logic board part numbers are divided up by their attributes. 1 IS - 2 L02A1 - 3 C - 4 IS15DBFP4RGB 1. IS Prefix. 2. The Logic Board base part number. The first number is the quantity of switch positions on the board. The second number is the version. 3. No code = No socket for IS switches. C = Sockets are soldered to the PCB for IS switches. 4. No code = No IS switches. IS15… = The logic board is populated by the IS Switches. Logic boards can be customized based on customer requirements.

Connectors The SmartSwitch Controller connects to the J1 of the first logic board via 14 pin ribbon cables. The J2 of the first logic board connect to J1 of the second logic board and so on. Illustration 1, Logic board connections Note: Attaching the ribbon cable without the red line on pin 1 on each of the headers may cause damage to the controller or the logic board.

Key Terms & Definitions Module NKK Switches’ LCD SmartSwitches and SmartDisplays. Host Any computer, terminal, or other device that can communicate over the RS232 line. Controller A PCB assembly that controls one or more logic boards and the switches associated with them. It communicates with a host over the RS232 line. Logic Board A PCB assembly with “glue logic” for mounting switches. It is controlled by a controller. Byte An eight bit hex value ranging from 00H to FFH (Decimal 0 to 255). The bit format of a byte is: (B7 B6 B5 B4 B3 B2 B1 B0) where B7 is most significant and bit B0 is least significant bit. Nibble/Hex digit A four bit value ranging from 0H to FH. A byte consists of two nibbles. ASCII A byte value representing a symbol. Communication Format There are two formats to transmit a byte: 1. Hex format - A hex byte is transmitted without any change to it. [xxH] will be used to denote this. All commands and some data are sent by using this format. 2. ASCII HEX format - Each nibble of the byte is converted to ASCII code and sent as a byte. [xxAH] will be used to denote this. For example, the hex byte 5AH is transmitted in two bytes, 35H and 41H. The ASCII value for 5 is 35H and the ASCII value for A is 41H. All addresses and most data are sent using this format. Address A one byte value ranging from 01H to FFH representing the 255 memory.
