Can be used to connect to Din of the next SWITCH. As a result, many 5 SWITCHES can be controlled with one clock and data signal. 6 FLM First Line Marker The marking signal for the first line data of LCD display . The first line of LCD will be selected by the falling edge of LP signal during the high level (FLM). 7 LP Latch Pulse Line data latch pulse will latch content of internal 40-bit shift register at falling edge for one line of display. LP will also increment the display line by one. 8 SCP Serial Clock Pulse Clock used by 40-bit internal shift register of the switch, shifting the display data bit presented at Din at falling edge. 9 Din Data Input Display serial data bit. Note: to map the display data, because of the difference between the number of internal shift register data (40) and the single line of LCD pixels (36), the first four bits of data shifted will be dummy bits. 10 GND Ground V Power Power source for logic circuit 11 DD 12 V Power Power source for LCD drive LC 13 BL-LED (+) Terminal of Backlight LED Anode for common 14 BL-LED () Terminal of Backlight LED Cathode for red www.nkkswitches.com E43 Supplement Accessories Indicators Touch Tilt Tactiles Slides Rotaries Keylocks Programmable Illuminated PB Pushbuttons Rockers Toggles
