of each terminal is identified by the character above the terminal. For example: A1 and B1
represent A and B of the first RS-485 interface, respectively, and L1 and H1 represent L and
H of the first CAN interface, respectively.
(3) Two rows of LEDs are the transceiver status indicators. The two lights on the green and red
are grouped together. There are 4 groups from left to right, which in turn correspond to the
4 interfaces of the above green terminals. The green light indicates reception and the red light
indicates transmission.
(4) Standard drawer mini SIM card slot. Above is the card of the 4G/GPRS module, below is the PSAM
card, press the yellow button on the right side of the drawer to pop up the drawer.
(5) This machine can update the system with SD card by inserting the prepared SD card into the card
slot, holding down the Boot button, clicking the Reset button, then releasing the Boot button
to boot from the SD card, waiting for the system to update itself. carry out.
(6) 12V power outlet is a 3-digit 3.81mm pitch green terminal with 12V+ on the left and 12V- on the
right, suspended in the middle.
(7) The left side of the power socket is the running indicator. When the power is running, the green
light is on. When the fault occurs, the red light is on. These two lights are directly driven
by the CPU's IO port and can be customized according to customer requirements.
(8) In the middle of the two USB sockets is the power indicator, and PG is the abbreviation of Power
Good. When the power supply voltage is higher than 8V, the green light is on, indicating that
the power supply is normal; otherwise, the green light is off and the CPU is informed of the
power failure. When the internal super capacitor supplies power to the whole machine, the red
light is on, indicating that the external power supply is faulty.
(1)
13-bit 3.81mm pitch green terminal contains 4 digital inputs and 4 digital outputs. From left to
right: Input1 to 4, Input common, and Output1 to 4. The digital input interface can withstand the
switching voltage signal within 24V DC, above 3V is high level, below 1V is low level. These input
ports are internally compatible and can be configured to supply 5V power to the unit according
to user requirements. The external only provides dry contact.
(2)
Bluetooth antenna.
(3)
Wi-Fi antenna.
(4)
4G secondary antenna.
(5)
4G main antenna. The main antenna is required, and the secondary antenna is used to enhance the
receiving effect. It is not necessary, but it is recommended to connect.
(6)
3-wire debug serial port, standard DB9 male socket, RS-232 level, no electrical isolation.
