This is hot off the production line, SPLat's new HMI700. It's just like the HMI430 but packs 7" of touchscreen goodness. Resolution is 800x480 and it's got a proper RS232 port as well as USB for programming, RS485, TTL serial, etc etc.

Here's a back view showing the connectors and battery holder for the real time clock.

The image on the left shows the HMI700 being used as the user interface for a water immersion treadmill.

Features

The HMI700 includes all of these features as standard:

• 8 x bi-direction digital pins (they can be any combination of inputs or outputs). As outputs, each can sink up to 500mA.
• 2 x analog inputs, each can be configured as either:Temperature, 0 - 20mA, 4 - 20mA, 0 - 10V, 0 - 3.3V.
• 1 x RS485 port, may be used for: MODBUS, Xwire expansion bus, or your own protocol.
• 2 x serial ports, both appear as TTL, one also appears as RS232.
• 300kHz(min) frequency counting input
• 100 year Real Time Clock with coin cell holder on-board. (bring your own battery).
• 7" 800 x 480 resistive touch LCD (hence it works with gloves).
• 1 x 0 - 10V analog output.
• Dimmable backlight.
• Beeper for making noise.
• USB interface for programming, font and image upload.
• Works with all our Xwire expansion boards.

Comparisons

This photo shows the size difference between the HMI430 & HMI700.

It also shows the difference in quality of displays as the HMI700 is clearly showing a whiter and brighter image.
