/

Power

Power use switching power supply(provided by customer)

/

Key

2x Key(Function Key, Active-low)

One of the key is used for key state software detection and restoring defaults.Another one is reserved.

11 Pin Connector

One pin is connected with DGND.Another 10 pins are connected
with 10 GPIO interfaces without related function.

/

Start Mode Circuit

DIP Switch x4

It’s used to choose boot mode(Boot from SD card/eMMC)

DI/DO

10x GPIO(5x output, 5x input). Voltage Driven( 12V ).

(Output driver relay,Active-high,Low level by default.

Input is separated by optocoupler, Active-low)

Software Specifications
OS

Use linux kernel+filesystem system.

Bootloader

Supports 100M Ethernet and boot from eMMC of SD card.Supports filesystem image burning.

Linux driver program

Devices driver system including CAN, UART, Ethernet and USB.

工作原理

  • Gateway receives the data from the BACNet bus.Data will be transported and process by CPU and then it will be output by RS485 or CAN BUS interface.On the other hand,gateway receives the data from RS485 or CAN BUS.After checking and judging,data will be sent to BACNet bus and transferred to long-distance computer or handheld terminal.
