H685 series should be installed and configured properly before putting in service. The installation and configuration should be done or supervise by qualified engineer.


Do not install H685 series or connect/disconnect its cable when it is power on.

2.4 SIM/UIM card installed

If your router has SIM/UIM card protector, please remove it, insert the sim card correctly, and fix the protector.

If your router has no SIM/UIM card protector, please insert the sim card correctly.


Attention: SIM/UIM card does not reach the designated position, the equipment cannot find a card, can’t work normally, therefore inserted a try to check again for a SIM card is stuck fast.

2.5 The installation of terminal blocks

This chapter is for version with terminal blocks only. Default, the H685 is with DB9 connector. Please use DB9 cable to connect H685 and the equipment directly.


The following is for version with terminal blocks only:

H685 uses pluggable terminals to connect the user’s data and the power supply. Spacing: 3.81mm,10 Pin; User data and power supply suggestion: 14~24AWG. Please refer to the table 2-4 for the interface definition of the power cable and connection sequence. Specific interface definition of the power cable and connection sequence you can read on the labels of H685 products. Using 14~24AWG cable and referring to H685 products labels or the bellowed interface definition and connection sequence, you need to use the oblate screw driver to fix the cable to the connecting jacks of the pluggable terminal. After successfully connection, you need to insert the terminal into the corresponding position in the bottom of the H685 products.


Notes: Connection sequence should be accurateCable’s insulating striping length is about 7mm. (For safety, insulating striping length should be too long). Please refer to the picture.


  1. The power cable should be connected correctly. We “suggestion double check before switch it on. Wrong connections may destroy the equipment.
  2. Power terminals: Pin 1 and Pin 2;
  3. HerePin 2 is “GND”, PIN 1 is power input “Vin” (DC5~40V, or DV5~50V).
