Note:

1. SD card slot, Ethernet interface and PS/2 interface are standard interfaces for

TTP-2410M/TTP-346M models, but optional for TTP-246M Plus/TTP-344M Plus models.

2. GPIO interface card includes SD card slot, Ethernet and PS/2 interfaces. So GPIO interface is

an factory option for TTP-2410M/TTP-346M, but a dealer option for TTP-246M Plus/TTP-344M

Plus models.
