• Fonts and icons storage: 32MB.
• Picture storage: 224MB, supporting up to 278 full-screen pictures.

3. RS232 and RS485 Serial Communication

The DMT80480T070_18WT supports both RS232 and RS485 serial communication through a 6-pin, 3.81mm Phoenix connector.

The communication specifications are:

• Minimum baud rate: 1200 bps.
• Typical baud rate: 115200 bps.
• Maximum baud rate: 230400 bps.
• Communication format: N81.

These interfaces allow the display to communicate with compatible PLCs, controllers, and embedded systems.

Important: The supplied datasheet specifies RS232 and RS485 interfaces. It does not identify a TTL/CMOS interface for this model. Check the actual hardware and connector documentation before connecting it to a microcontroller's TTL-level UART.

4. SD Card Interface

The module includes an SD/SDHC card slot supporting the FAT32 file system.

The SD card can be used to download and upgrade:

• Display pictures.
