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.
