This product has been designed to simplify the implementation of TFT technology into your product. The high level text based object oriented command structure, entity library and 50 page screen memory allow most of the processing to be undertaken by the TFT module leaving the host CPU to concentrate on the core application processes. This allows proven firmware running on small 8 bit microcontrollers to be modified to drive this TFT module with a minimum of work and risk.

5V pins are common un-fused input /outputs. 3V3 pins are outputs only with a total 50mA capacity. Do not connect pins '-' or NC
Half duplex uses connector CN1 pins 1 and 8.

The square pad always indicates Pin1

Jumper and Additional Connector Information


Function Note
BT1 Battery Connector Apply solder bump to center pad before fitting holder. CR2032 battery positive up.
BATT1 RTC alternate power 3VDC Apply right angle connector top side soldered.
BL LED Backlight alternate supply When the backlight is software disabled, 30VDC at 20mA can be applied by the user.
J4 RTS Jumper Solder 1 and 2 for RTS.
J8 RS485 Half Duplex Jumper Solder 1 and 2 for Full Duplex, Solder 2 and 3 for Half Duplex
J15 RTS+RS4/DTR Jumper Solder 1 and 2 for RTS and RS485 if fitted, solder 2 and 3 for DTR when RS485 not fitted.
J16 CTS+RS4/DSR Jumper Solder 1 and 2 for CTS and RS485 if fitted, solder 2 and 3 for DSR when RS485 not fitted.
xWP Write protect jumpers Solder to prevent data update of non volatile memory where fitted.N=Nand, EE=EEPROM.
J46 5V supply on Pin10 on CN1 Solder this jumper to connect the 5V supply to Pin 10 on CN 1

Note: RTS/CTS or DTR/DSR can be selected, not both. When RS485 fitted in model K611A1xx then only RTS/CTS are possible.
