3. Setting up the receiver
3.1 Guidelines
Please follow these guidelines when setting up your receiver.
3.1.1 Environmental requirements
To keep the receiver with a reliable performance, it is better to use the receiver in
safe environmental conditions.
•Operating temperature: -40°C to +80°C
•Storage temperature: -45°C to +85°C
•Out of corrosive fluids and gases
3.1.2 Power supply
The M300Pro has a built-in internal Lithium battery, which can work for up to 16
hours. If you set M300Pro as a permanent site (reference station), a uninterruptible
power supply (UPS) is recommended to protect receivers from power surges and
power outage.
3.1.3 Mounting the antenna
Choosing the optimal location for the GNSS antenna is critical to the performance
quality of your M300Pro receiver. Poor or incorrect placement of the antenna may
impact the accuracy and reliability of observation, resulting a degraded performance
of normal operation.
Follow these guidelines to select the antenna location:
If the application is mobile / kinematic, place the antenna on a flat surface

M300 Pro GNSS Receiver User Guide

along the centerline of the vehicle.
Choose an area with open view to the sky and far from metallic objects.
Avoid areas with high vibration, excessive heat, electrical interference or
strong magnetic fields.
Avoid mounting the antenna close to electrical cables, metal masts and
generally close to other antennas
AT-series antenna is recommended, if use other kinds of antenna please check the
specifications with the ComNav support team.
3.1.4 M300Pro connection view
M300Pro is mainly used as a CORS reference station, the below figure explains the
connection of each equipment. The GNSS antenna and lighting rod are fixed on the

4. Receiver configuration through a Web Browser
M300Pro has the advanced built-in web server, you can access the web setting page
and do configurations remotely. This section describes how to change receiver’s
settings through a web server.
4.1 Login the configuration page of M300Pro
The M300Pro receiver can connect to an Ethernet network through its Ethernet port.
It means that you can configure and monitor the receiver’s settings without serial
cable connection.
1. Firstly, make sure that the M300Pro and your computer are within the same
Local Area Network (LAN). Then change your receiver’IP address through the
front panel based on your office computer. For example IP address in your
computer:
IP address of M300Pro:
2. Enter the IP address and HTTP port of the receiver into the address bar, you will
access the configuration page of M300Pro.The default setting for the HTTP port
is 80, which is the standard port for web servers. However, HTTP port need to be
changed in some cases.
For example, using default port 80:http://192.168.1.148
If your receiver has a port other than 80, you must enter the IP address followed by
