1.1 Safety Information
1.1.1 Warnings and Cautions
An absence of specific alerts does not mean that there are no safety risks involved.
A Warning or Caution information is intended to minimize the risk of personal injury
and/or damage to the equipment.
WARNING - A Warning alerts you to a potential misused or wrong setting of the
equipment.
CAUTION - A Caution alerts you to a possible risk of serious injury to your person
and/or damage to the equipment.
1.1.2 Regulations and Safety
The receivers contain a built-in wireless modem for signal communication through
Bluetooth® wireless technology or through external communication datalink.
Regulations regarding the use of the wireless modem vary greatly from country to
country. In some countries, the unit can be used without obtaining an end-user license.
However, in some countries, the administrative permissions are required. For license
information, consult your local dealer. Bluetooth® operates in license-free bands.
Before operating a E91 GNSS receiver, determine if authorization or a license to

2.1 About the Receiver
The E91 GNSS receiver incorporates a GNSS engine, GNSS antenna, internal radio (410
MHz – 470 MHz), 4G cellular modem, Bluetooth and Wi-Fi in a ruggedized and
miniature unit that is easy for you to set up an all-in-one RTK rover or mobile base
station. Bluetooth and Wi-Fi technology provide cable-free communication between
the receiver and controller.
The receiver can be used as the part of a RTK GNSS system with HUAYI NAV LandStar
7 software. And you can download the GNSS data that recorded in the internal
memory of receiver to a computer.
To configure the receiver for performing a wide variety of functions, you can use the
web interface by connecting the receiver with PC or smartphone through Wi-Fi.
2.2 Parts of the Receiver
The operating controls are all located on the front panel. SIM card slot are on the
backside. Serial ports and connectors are located on the bottom of the unit.

Works as a Power button.
Function Button
Turn on/off the static data recording:
•Switch to static mode when pressed for 3 s, the
static LED (orange) shines for 2 s.
If press the function button quickly:
•If E91 works with RTK mode, the static LED (orange)
will flash.
•If E91 is recording static data, the correction LED
(green) will flash.

2.3.2 External Power Supply
There is one recommended method for providing the external power (9 V DC to 36 V
DC):
Connect the receiver to a vehicle battery by using the external power cable.
WARNING - Use caution when connecting external power cable's clip leads to a
vehicle battery. Do not allow any metal object to connect (short) the battery's positive
(+) terminal to either the negative (-) terminal or the metal part of the vehicle battery.
This could result in high current, arcing, and high temperatures, exposing the user to
possible injury.
2.4 Inserting SIM Card
(a) Open the cover.
(b) Insert the SIM card with the contacts facing upward, as indicated by the SIM card
icon next to the SIM card slot.
(c) Close the cover to prevent water immersion.
(d) To eject the SIM card, slightly push it in to trigger the spring-loaded release
mechanism.
Note: The SIM card is provided by your cellular network service provider.

2.6 Downloading Logged Data
Data logging involves the collection of GNSS measurement data over a period at a
static point or points, and subsequent post-processing of the information to accurately
compute baseline information. Data logging using receivers requires access to suitable
GNSS post-processing software such as the HUAYI NAV Geomatics Office Software 2.0
(CGO 2.0).
2.6.1 FTP Download
The procedures of downloading logged data through FTP are as follows:
Switch on the receiver, search its Wi-Fi in the computer and connect.
After the successful connection, open the file manager in the computer and input
“ftp:\\192.168.1.1” in the address box.
Input user name and password, the default user name and password are “ftp”.

Getting Started with E91

Double click the folder “repo_receiver SN” (take 3203970 as example), you will
see 9 folders. The “push_log” folder is used to save the log files, and the other 8
folders represent different logging sessions and are used for store static data.
Double click the folder that you have configured to store the static data, you will
see the folder(s) created by the E91 system automatically and named by the date
which is decide by GPS time when you start to log data.
Select the destination folder and double click it, two folders named as different
data format (hcn and rinex) will be displayed.
Select the data format that you has configured to save the static data, you will find
the static raw data.

Getting Started with E91
19
Notes: For hcn files, the name of the file is represented as XXXXXXDDDNN, where
XXXXXX is the SN of the receiver, DDD is day of year, and NN is the recording session.
WARNING – The static data will be saved in the first logging session, the
“record_1” folder, by default. Old files will be deleted if the storage space is full. If you
configure not to auto delete old files when the memory is low, the receiver will stop
data logging.
2.6.2 Web Server Download
The procedures of downloading logged data through web server refer to 5.4.4 Data
Download Submenu.
2.6.3 USB Download
The procedures of downloading logged data through USB cable are as follows:
Switch on the receiver, and connect it with a computer by USB Cable. After the
successful connection, a removable disk named as the Serial Number (SN) of the
receiver will appear on the computer.
Double click the removable disk and you will see the folder named as
“repo_receiver SN” (take 3203970 as example).
Double click this folder, you will see 9 folders. The “push_log” folder is used to
save the log files, and the other 8 folders represent different logging session and
are used for store static data.
