2) Find the modem type info at the back cover of the router. This will be used while do
configuration.
For example: the following label indicates the version, type and inside module modem.
The module modem name is “ME909s-821”, remember this and will select this module name while
do configuration.
1.2 Prepare SIM Card and working condition
1. H685 router has different version. Study your router version before installation.
2. For GSM/GPRS/EDGE/HSDPA/HSUPA/HSPA/HSPA+/4G LTE version, please get a SIM
card with data business.
3. For CDMA2000 EVDO/CDMA1x version, please get a UIM card with data business or
inform us before order if the network uses non-ruim (nam-flashing).
4. Make sure the sim card or uim card is with enough data business and balance.
5. Make sure the signal is good enough where you test or install the router. Weak signal will
make the router no work. If you find your signal strength is not good, please contact us for
high gain antenna.
6. Different countries and carriers use different network band and frequency. E-Lins packs
units with free world-wide-use antenna. It can work, but the data speed or signal may not be
good at your sites. Please buy dedicated high gain antenna from your local suppliers or
contact E-Lins to OEM/ODM the antenna.
1.3 Highly recommendation for the configuration
The wireless cellular is unstable sometimes with some uncertain issue. In order to keep the

2.3 Installment
H685 series should be installed and configured properly before putting in service. The
installation and configuration should be done or supervise by qualified engineer.
Attention:
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 can not
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

H685 User Manual
E-Lins Technology Co.,Limited
Tel: [phone] E-mail: [e-mail] www.szelins.com www.e-lins.com
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 accurate。Cable’s insulating striping length is
about 7mm. (For safety, insulating striping length should be too long). Please refer
to the picture.
Attention:
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.Here ： Pin 2 is “GND”, PIN 1 is power input “Vin”(DC5~40V, or DV5~50V).

2.6 Grounding
To ensure a safe, stable and reliable H685 series operation, Router cabinet should be
grounded properly.
2.7 Power Supply
H685 series can be applied to complicated external environment and usually the power
range is very large. So in order to fit the complicated application environment and improve
the stability of the system, H685 series is designed with advanced power management
technology. The DC power supply electronic to the device via the pluggable terminal PIN
2(GND) and PIN 1(Vin). Please refer to the above table for the detail definition of the
terminal.
Normally, H685 series input powers supply is +5～+40V (if your H685 support 50V, the
option is +5~+50V). In most cases, the standard configuration is 12V/1A.
