Driver identification, temperature sensors, NVRAM, digital I/O and analog input are quite often used on vehicle and M2M applications. 1-Wire is a device communications bus system designed by Dallas Semiconductor Corp. that provides low-speed data, signaling, and power over a single signal.
At this time, there are approximately 40 1-wire devices available from Dallas Semiconductor Corp. 1-Wire devices can be grouped by their functions into several categories:
‧Identification plus temperature
‧Identification plus temperature logger
‧Identification plus temperature and humidity logger
‧Identification plus real time clock
‧Identification plus NV SRAM or OTP EPROM or EEPROM
‧Identification plus SHA-1 secure EEPROM
Thanks to the integration of 1-wire interface into Acrosser In-Vehicle Computers, so system integrators now can use one simple interface to connect variety devices which are often utilized in telematics applications. Beside the hardware interface, Acrosser also provide software API to write and read data to and from any kind of 1-wire devices.
Combo Connector Simplifies Many Cables Down to a Single Cable
Signals between a vehicle computer and a touch monitors include VGA, USB, audio and power supply of touch monitor. With a normal design, 4 cables are required. The all-in-one combo connector integrates all of these signals into one single cable. This significantly simplified the routing of the harness. Acrosser’s new in-vehicle computers and in-vehicle touch monitors are all featured with this advanced design.
Remote Power Control Switch, ON/OFF Control become More Flexible
All Acrosser’s In-Vehicle Computers are featured with a remote power control switch beside the power control by ignition switch. When this switch is installed and enabled by software, the switch works together with the ignition switch to control the power on/off of the computer. This has enabled the driver be able to turn off the computer without turning off the ignition. This feature is very useful in some application scenarios.
