HMI device runs Linux on 7 inch touchscreen

Dec 11, 2007 — by Jonathan Angel — from the LinuxDevices Archive — 142 views

Kontron has added a smaller, “cost conscious” LCD option to its line of thin-client HMI (human-machine interface) subsystems. The [email protected] Micro Client is based on the company's ETX-format SBCs (single-board computers), has a touchscreen LCD, and supports Linux.

The [email protected] Micro Client targets a wide variety of thin client, web client, user terminal, and control-oriented applications, according to the company. Except for its 7-inch WVGA (800×480) display and smaller overall size, the device is technically similar to the 15-inch [email protected] that occupies the top of the Micro Client range.

The device is offered with processors up to a 600MHz Celeron M, and with up to 1GB of SDRAM. Standard communication ports include 10/100 Ethernet, two USB, and one RS232 (RS422/485 optional). Other optional features include CAN bus, battery backed SRAM, and function keys.

Thanks to a passive cooling design, the unit's installation depth is just under 2 inches, or about 50 mm, according to Kontron. The front panel is sealed to IP65 and, unlike the larger devices in the Micro Client series, the [email protected] is VESA-mountable.

Features and specifications cited by Kontron include:

  • Processor — up to 600MHz Celeron
  • Memory — up to 1GB
  • Display:
    • 7-inch TFT touchscreen

    • 800 x 480 resolution
    • 330-nit brightness
  • Networking — 2 x 10/100 Ethernet
  • Other I/O:
    • 2 x USB 2.0
    • 1 x RS232 (RS422/485 optional)
    • CAN bus (optional)
  • Expansion — CompactFlash
  • Operating temperature — 0 to 50 deg. C
  • Dimensions — 9.25 x 6.6 x 1.9 inches (235 x 168 x 49 mm)

In addition to Linux, Kontron also provides support for Windows CE and Windows XP Embedded. The selected embedded OS is available pre-installed on a CompactFlash card, Kontron says.

The [email protected] appears to be immediately available, but the company has not disclosed pricing information.
