Note:
1. SD card slot, Ethernet interface and PS/2 interface are standard
interfaces for TTP-2410M Pro/TTP-346M Pro/TTP-644M Pro
models (*Industrial model), but optional for TTP-246M
Pro/TTP-344M Pro models (*Economy model).
2. GPIO interface card includes SD card slot, Ethernet and PS/2
interfaces. So GPIO interface is an factory option for TTP-2410M
Pro/TTP-346M Pro/TTP-644M Pro, but a dealer option for
TTP-246M Pro/TTP-344M Pro models.
