【Mounting Dimension】
Unit: mm

Note:
Don't place or install the device in area near water or moist,
keep the relative humidity of the device surrounding between
5%~95% without condensation.
Before power on, first confirm the supported power supply
specification to avoid over-voltage damaging the device.
The device surface temperature is high after running; please
don't directly contact to avoid scalding.
【Wall-mounting】
Step 1 Place the device on the wall of device mounting as
reference or refer to the installation dimension to
mark the position of the two screws.
Step 2 Fix the M4 screw in the wall and reserve 2mm
interspace
Step 3 Hang the device on the two screws and slide
downward, and then tighten the screws, mounting
ends.
【Disassembling Wall-mounting Device】
Power off the device.Step 1
Unscrew the screws in the wall about 2mm.Step 2
Lift upward the device lightly to remove the device,Step 3 disassembling ends.
Note:
Power ON operation: First insert the power supply terminal
block into the device power supply interface, and then plug the
power supply socket and power on.
Power OFF operation: First, unpin the power supply plug. And
then remove the connector of the terminal block. Please notice
the operation order above.
【Power Supply Connection】
The top panel of CAN485 interface converter
provides 2-pin industrial terminal blocks (DC IN),
thereinto, DC IN is 9~48VDC power supply
input. Power supply supports nonpolarity.
【DIP Switch Settings】
4-pin DIP switches are provided for function
settings, among which “ON”is enabling valid
end.
DIP switches definition as follows:

Configuration
mode settings
Dial the DIP to ON, the
converter enters into
“configuration”mode after being
powered on;
Dial down the DIP, the
converter enters into “normal
operation”mode after being
powered on.

Dial the DIP to ON, the device
will automatically reboot and
restore factory defaults, dial
back the DIP.

Pin 4 is marked with “Res+”and pin 5 is marked with “Res-”,
which are connected to the terminal resistance of CAN
network. When CAN485 converter serves as CAN-bus
network terminal, two pins are connected by 120 ohms
resistor; otherwise it’s useless to install 120 ohms resistor.
【RS-485 Serial Port】As for the CAN485, RS-485 ports
adopt standard DB9 male, pin
definition conforms to RS-485
norm. Here three-wire connection
is adopted.
