Interfaces

Smart LCD provide 5 kind of communication interface which depends on model. Some of the model provide more than one interface.

RS-232C interface

  • the major application interface in TOPWAY Smart LCD Series
  • provides versatile on screen UI function features of TOPWAY Smart LCD
  • receives command from host motherboard and provides response
  • uses standard RS-232C signaling
  • TOPWAY serial commands protocol (same as UART interface)

UART interface

  • available as an individual TOPWAY Smart LCD product
  • provides the same versatile on screen UI features
  • uses 3.3V logic levels UART signaling
  • TOPWAY serial commands protocol (same as RS-232C interface)

RS-485 MODBUS Host interface

  • available as an individual TOPWAY Smart LCD product
  • provides the same versatile on screen UI features
  • working as a MODBUS host device
  • uses standard RS-485 signaling
  • with MODBUS protocol
  • support programable script to access (R/W) MODBUS slave devices

RS-485 MODBUS Slave interface

  • available as an individual product of TOPWAY Smart LCD
  • provides the same versatile on screen UI features
  • uses standard RS-485 signaling
  • with MODBUS protocol
  • support direct mapping the MODBUS address with internal VP_N16 variable

Ethernet interface

  • available as an individual product of TOPWAY Smart LCD
  • provides the same versatile on screen UI features
  • uses standard ethernet signaling
  • with TCP/IP protocol
  • accept TOPWAY serial commands

Interface Terminal

There are mainly two terminals on a Smart LCD

  • Power supply and signal terminal for operation
  • USB terminal for pre-load display project

Power Supply and Signal Terminal (for operation)

outlook terminal type Pinout
10pin FFC terminal (P1.0) 1-3:VDD, 4:NC, 5:Rx, 6:Tx, 7:NC, 8-10:GND
8pin header (P2.5) 1-2:VDD, 3: NC, 4:Tx, 5-6:Rx, 7-8:GND
6pin header (P3.5) Pins defined for RS232C/RS485/UART and power supply (Please refer to products handbook)
6pin TH (P3.5) Pins defined for RS232C/RS485/UART and power supply (Please refer to products handbook)
10pin TH (P2.0) 1-3: VDD, 4:NC, 5:Rx, 6:Tx, 7:NC, 8-10:GND
8pin header (P2.0) 1-2:VDD, 3:NC, 4:Tx, 5-6:Rx, 7-8:GND
LAN header (RJ45) Standard Ethernet (not support POE) for display project update via network. Power should be supply externally.

note.

  • Terminals shows here are standard terminal for Smart LCD. Please refer to the product user manual for details (No customized product)
  • Be aware the signal leveling for Rx and Tx. RS232 signal can damage UART terminal device. Miss-matched signal level is not allowed.
  • Please re-confirm the power supply voltage before power on the Smart LCD.

USB terminal (for pre-load display project)

outlook terminal type description
Mini USB Connect to PC for display project download. (*1)

Connect to a U-drive via an OTG cable (and power on the Smart LCD) for auto loading display project image that stored in U-drive. (*2)

USB type A Plug in a U-drive (and power on the Smart LCD) for auto loading display project image that stored in U-drive. (*2)
USB type C Connect to PC for display project download (*1)

Connect to an U-drive via an OTG cable (and power on the Smart LCD) for auto loading display project image that stored in U-drive. (*2)

note.

  • *1.   PC download display project sequence (use PC onboard USB for good signal and power supply)
    • no need external power supply
    • connect to PC
    • use SGTools to download the display project
    • dis-connect form PC
  • *2.   U-drive copy display project sequence
    • plug the U-drive (with OTG cable) to the Smart LCD USB terminal
    • power on the Smart LCD
    • wait until image copy to be finished
    • power off the Smart LCD
    • unplug the U-drive (with OTG cable)
