tighten it with M4 screws to the marked position.
Mounting ends.
Disassembling Device
Step 1 Device power off.
Step 2 Hold the equipment steady and unscrew the screw
on the wall
Step 3 Take out the device, disassembling ends.
Note before powering on:
Power ON operation: First insert the power supply
terminal block into the device power supply interface,
and then plug the power supply plug contact and power
on.
Power OFF operation: first unpin the power plug, then
remove the power line, please note the operation order
above.
【Power Supply Connection】
12~48VDC power supply
Model I provides 3-pin 5.08mm pitch industrial
terminal blocks, in which V+ and V- are DC input.
FG is the shell or grounding. The power supply
supports non-polarity connection, and the
equipment can still work normally after reverse
connection. Voltage range: 12~48VDC.
100~240VAC Power Supply
Model II provides 3-Pin 5.08mm pitch industrial
terminal blocks, in which L/+ and N/- are AC input.
FG is the shell or grounding. Supports 220 VAC
power supply input. Voltage range: 100~240VAC.
【DIP Switch Settings】
The device provides 4 pins DIP switch for
function setting, in which “ON” is the enabled end.
DIP switch definition and operation method are
as follows:
DIP Definition Operation
1 Master/slave device
Set the DIP Switch to
“ON” and the device
works as the master
device of the ring network;
Cancel setting of DIP
Switch to “ON” , device
works as ring network
slave device.
Notes:
The serial port fiber MODEM should be used in pairs,
and the serial port number on the two devices should be
one-to-one correspondence.
If the device passes through the fiber interface group
ring, the ring network main station shall be enabled by
the DIP switch, that is, one master device and one slave
device.
【Serial Port Connection】
RS-485 serial port
The RS-485 serial port provided by the
products of this series is 5-pin 3.81mm pitch
industrial terminal blocks. The pin definitions
are shown in the table below:
PIN 1 2 3 4 5
RS-485 D+(A) D-(B) GND — —
【Checking LED Indicator】
The device provides LED indicators to monitor the device
working status with a comprehensive simplified
troubleshooting; the function of each LED is described in the
table as below:
