1. Introduction
Thank you for choosing the M600 GNSS receiver.
This User Guide provides you a detailed introduction of receiver installation, setting
up, as well as frequently asked questions. It will help you get quickly started with
M600 receiver.
1.1 About the receiver
M600 is a dual-frequency GNSS receiver with two antenna systems, which is
designed for high-precision applications. It can provide quick and precise positioning
and heading information even in a harsh environment. Therefore, M600 receiver is
an optimal option for a wide range of static and mobile carriers, such as moving
vehicles, ships, harbor construction andaircraft.
1.2 Receiver Features
There are top features of M600 receiver, including:
Dual antenna system
GPS+BeiDou/ GLONASS Dual constellation system
A wide range of data output
Over current and voltage protection system built-in
The detailed technical specification, please see Appendix A 

2. Installing the receiver
This chapter describes how to install the antenna, M600 receiver and cable
connections.
2.1 Installing the Antenna
To improve the performance of receivers and acquire high-precision position
accuracy, it is necessary to mount the antenna to the optimal position in a proper
way. Antennas must be installed:
Outdoors with a clear view of sky
In a level plane
Away from obstructions
Away from other radio frequency and electronic devices
Along the center line of the carriers
The M600 receiver is linked with two antennas, primary antenna is connected to
Master, and secondary antenna is connected to the Slave. AT300 antenna is
recommended, if use other kinds of antenna please check the specifications with the
ComNav support team. Please install antennas in the proper position based on your
requirement.
Radio Antenna(optional)

To mount the stable antennas, there are various mounting types you can choose,
including magnetic mount, pole mount and rail mount. The following picture shows
the antenna mounted with the magnetic mount.
2.2 Mounting the Receiver
M600 receiver is desired with a bracket at the bottom, which can be easily mounted
to desired location. However, GNSS receivers are disturbed by radio equipment,
please make sure that the M600 receiver is mounted:
Away from wireless bridge, router, signal isolatoretc.
in a location that minimizes vibration, extreme temperatures and moisture
Power supply within 10.5~28 VDC, and properelectrode
Be careful about the range of input voltage if using external radio 
With secure cable connection
Screw down the brackets in your desired location as figure below:

2.3 Cable connections and indicator lights
This section introduces the cable connections and the indicator lights. The following
figure explains the connection of each component.
1 GNSS1: Connected to the Master (positioning);
2 GNSS2: Connected to the Slave (heading);
3 UHF：TNC UHF antenna connector;
4 DC/: Input commands for master station, 12V power supply input,
also output heading and positioning information;
DC/: Input commands for slave station, communicated with internal UHF.
Note: the heading and positioning information only can be outputted from DC1 port. For
detailed information of 7-pin Lemo cable, please see Appendix B
According to LED lights, you can check the work status of your receiver.
PWR: Power indicator. The LED will light in red color when poweredon.
SAT1: Satellite indicator of master station (GNSS 1), it will flash based on the
number of locked satellites.
SAT2: satellite indicator of slave station (GNSS 2), as the same meaning as SAT1.
LINK: correction message. As a base station, flashing once per second means
that it sends one correction message per second; as a rover, it means receiving
correction message. In the raw data recording mode, data is recorded in the
memory of the receiver, and LINK indicator will flash according to the sampling
interval of Mater.

3. Setting up the receiver
3.1 Required software
The required software can be downloaded from ComNav Website, or you can contact
our technical support.
Compass Receiver Utility (CRU): Software to configure the receiver
U20_V1.16.exe: Software to configure the radio settings
3.2 Power supply
The M600 GNSS receiver has no built-in battery, which only can work with an extra
power supply. The proper voltage range is from 10.5VDC to 28VDC. Power supply is
connected through 7-pin Lemo to RS232 Cable (as the picture below):
3.3 Guidelines
This chapter describes guidelines to set up the receiver and output position message
through programmatic commands. Please read these notes before sending
commands to your M600 receiver.
 Select and send proper commands, all commands are case insensitive:Log
version=LOG VERSION
 Press Enter button at the end of every command, then input other commands
 For More detailed programmatic commands, please refer to ComNav OEM
CARD REFERENCE MANUAL
 The default baud rate is 115200bps, set the same baud rate when sending
commands through DC1 or DC3.
