1 Preparation job before configuration
1.1 Learn your router version and feature
1) H750 series contains different version and option feature. Please learn it before using it.
H750 series defines the model as follows,
Notes: please be informed the following features are option. Please indicate with

H750 User Manual

Tel: [phone] E-mail: [e-mail] www.e-lins.com
your orders.
1) WiFi Feature
2) GPS / GNSS feature
3) Serial to cellular feature, RS232 or RS485 can choose one
4) Voice/SMS control
5) DC5V~60V
6) BGP, OSPF, RIP, etc.
7) DIO (digital input and output feature)
8) RMS (Remote Management System)
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 “MC7304”, remember this and will select this module name while do
configuration.
1.2 Prepare SIM Card and working condition
1. H750 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
router working in the best condition, it is highly recommended that the Cell ICMP Check
feature is activated. Please refer to chapter 3.5.1 to configure.

2.3 Installment
H750 series should be installed and configured properly before putting in service. The
installation and configuration should be done or supervise by qualified engineer.
Notes:
Do not install H750 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.
Notes:
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
The following is for version with terminal blocks only:
H750 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
H750 products. Using 14~24AWG cable and referring to H750 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 H750 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.

2.6 Grounding
To ensure a safe, stable and reliable H750 series operation, Router cabinet should be
grounded properly.
2.7 Power Supply
H750 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, H750 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, H750 series input powers supply is +5～+40V (if your H750 support 50V, the
option is +5~+50V). In most cases, the standard configuration is 12V/1A.
Attention:
The H750 supports POE (Power over Ethernet). It supports 5-40VDC default, it the POE
voltage is 48V, please order 5-60VDC version, otherwise it will defeat the hardware of H750.
2.8 LED and Check Network Status
Please connect the antenna after you successfully connect to the cable. And then insert the
valid SIM/UIM card and provide the power to the H750 series via the cable. After provide the
