Rugged in-vehicle PC offers CAN and video connectivity

Mar 16, 2011 — by Eric Brown — from the LinuxDevices Archive

Grayhill announced a 10.4-inch rugged, IP67-sealed display computer for off-highway vehicles. The “3D104” integrates a 416MHz Marvell PXA270 processor with 64MB SDRAM and 64MB NAND flash, and offers a 10.4-inch, backlit SVGA LCD with optional touchscreen support, three CAN bus ports, Ethernet and USB ports, two serial ports, three NTSC/PAL inputs, and five GPIOs, says the company.

The 3D104 is designed for displaying monitoring gauges, diagnostic menus, and video feeds on off-highway vehicles such as construction equipment and agricultural work vehicles, says Grayhill. Like an earlier 6.5-inch model, it's powered by the Marvell PXA270 processor clocked at 416MHz. The CPU is said to be capable of smoothly running three simultaneous video feeds, which are available via three NTSC/PAL inputs on the computer.

The 3D104 is equipped with 64MB of memory and 64MB of flash storage, and has a sunlight-readable 10.4-inch, 800 x 600 display with a 400-nit brightness rating, says Grayhill. A touchscreen is optional — otherwise, operators can use the seven soft-keys that are positioned beneath the display.

In addition, Grayhill's CAN-bus keypads or Vehicle Display Controller (VDC) can interface with the 3D104, says Grayhill. The 3D104 offers a 10/100 Ethernet port, a USB port, two serial ports, and three CAN bus ports, the latter used to "facilitate communication with the vehicle's ECU," says the company. Other I/O includes three GPIO out and two GPIO in.

Sealed to IP67 standards, the computer offers ruggedization support and protection against the elements compliant with ANSI/ASAE EP455, says Grayhill. The 3D104 can operate at temperatures ranging from -22 to 149 deg. F, says the company.

The computer ships with either Linux or Windows CE. Grayhill can also develop custom dashboards and control panels based on the 3D104 "to meet the unique price, performance and aesthetic requirements of vehicle OEMs," says the company.
