1. Introduction

RTK-M100 system pro uct is ual-frequency multi-constellation RTK evices, Embe e

NXP® i.MX 6 (Automotive Gra e) high-en processor an provi es centimeter-accurate GNSS

measurements. All of them can work in base station or rover. There are two communication

interfaces, inclu ing Ethernet, 4G/LTE. Through these built-in communication functions for

local or coul ata center communication with the external host.

RTK-M100 system have not only 64M bytes on-boar flash memory for saving up to 7 ays

of RTK position ata, but also a micro SD interface to log RTK position ata an GNSS raw ata

for post processing. In a ition, light weight an low power consumption make RTK-M100

pro uct series easy to use.

4. Hardware description

4.1. Block diagram

4.2. thernet connector

The pro uct oes not support the hot plug of Ethernet. If Ethernet is going to be use ,

please insert Ethernet cable before turning on the power of the pro uct.

4.3. Mini USB connector

The pro uct is powere through Mini USB connector. PC’s USB port, 5V power bank or

5V/1A a aptor can power the pro uct. Mini USB connector is also use for communication with

PC’s software tool RTKFox. The optional internal battery of the pro uct is charge through Mini

USB connector, too.

4.4. Micro SD connector

The pro uct supports hot plug of micro SD car with FAT32, ex: FAT or NTFS file system. The

user can save RTK position ata an GNSS raw ata to micro SD car for post processing.

4.5. I/O connector

The 8-position I/O connector of the pro uct is compatible with Hirose’s DF13 series. The

pin escription of the connector is in the following.

Pin 1: CANL, CAN Low-Level Voltage I/O.

Pin 2: CANH, CAN High-Level Voltage I/O.

Pin 3: GND, groun .

RTK-M100 User’s Manual

Page 5of14

Pin 4: IO_PWR, power input for IO pin 1 ~ 4. Input voltage range is 3.3V~5.5V.

Pin 5: IO_01, general purpose IO pin 1. Logic level is base on the voltage of IO_PWR.

Pin 6: IO_02, general purpose IO pin 2. Logic level is base on the voltage of IO_PWR.

Pin 7: IO_03, general purpose IO pin 3. Logic level is base on the voltage of IO_PWR.

Pin 8: IO_PWM, general purpose IO pin 4.Logic level is base on the voltage of IO_PWR.

4.6. Serial port connector

The external host CPU can communicate with the pro uct through the serial port. The

protocol is 115200-8-N-1 (115200 bau , 8 ata bits, no parity, 1 stop bit). The 6-position

connector of the serial port is compatible with Hirose’s DF13 series. The pin escription of the

connector is in the following.

Pin 1: NC, not connecte .

Pin 2: TX, transmit ata to the external evice. (3.3V)

Pin 3: RX, receive ata from the external evice. (3.3V)

Pin 4: NC, not connecte .

Pin 5: PPS, pulse per secon .

Pin 6: GND, groun .

TX an RX signals of the serial port an USB-UART bri ge IC connect to the same UART port

of the pro uct’s internal CPU mo ule. If both serial port an Mini USB connector are connecte ,

the serial port will ominate the communication with the internal CPU mo ule.

4.7. RF connectors of RTK antenna

The pro uct supplies the e icate 3.3V power to the external GNSS antennas through RF

connectors of RTK mo ule. It has built-in antenna short circuit protection. The pro uct can

etect RTK antenna connection status. If RTK antenna is not properly connecte , green LED will

be always on.

4.8. RF connector of 4G/LT

Connect 4G/LTE antenna before turning on the power of the pro uct. If the pro uct

successfully registers to the network of the telecom provi er, the yellow LED will blink once

every secon .

4.9. L D

The pro uct has three LEDs. The colors are re , yellow an green. Detail escription is in

the following table.

L D State Description

Red Blink (on/off: 500ms) The pro uct is working.

Yellow

Blink (on/off: 500ms) Successfully register to the network of the telecom provi er

through 4G/LTE.

Blink (on/off:250ms) Not register to the network of the telecom provi er through

4G/LTE

Green

Always on RTK antenna is not properly connecte .

Blink (on/off:100ms) Data log function has been enable , but fails to etect the

micro SD car or internal flash memory is full.

Blink (on/off:300ms)

•Rover mo e: RTK fix is not available.

•Base station mo e: Survey-In is not complete.

Blink (on/off:500ms)

•Rover mo e: RTK fix.

•Base station mo e: Survey-In is complete.

5. Installation of SIM card

First, power off the pro uct an confirm the re LED is off. Then remove 8 screws of the

pro uct an pull out the PCB boar . The SIM car hol er is on the bottom si e of the PCB

boar shown as below picture. Prepare a micro SIM car with no PIN lock, an insert into SIM

car hol er. Then put PCB boar back into the metal box of the pro uct an tighten the screws.

Now SIM car is installe .

6. Getting started

1. Install USB river for MS Win ows. It can be ownloa e at

http://www.prolific.com.tw/UserFiles/files/PL2303_Prolific_DriverInstaller_v1200.zip.

2. If Ethernet is going to be use , plug in Ethernet cable before power on the pro uct.

3. If 4G/LTE is going to be use , insert a micro SIM car with no PIN lock as escribe in the

section 5. Attach 4G/LTE antenna.

4. Connect Mini USB cable to the pro uct an the computer. A COM port will be enumerate

in the Device Manager of MS Win ows.

5. Press the re button to power on the pro uct. The re LED of the pro uct will be on

imme iately. Wait for up to 1 minute until the re LED blinks. The pro uct starts an rea y

for control.

6. Now you can run PC software tool RTKFox to evaluate the pro uct.

7. Configuration examples

RTK-M100 pro uct series can work in three ifferent mo es, inclu ing rover, base station

an sensor mo e. The user can use PC software tool RTKFox to configure. After finishing the

steps in section 6, RTKFox starts as below. Select COM port that the pro uct is connecte .

If RTKFox connects to the pro uct successfully, all buttons are enable as below.

7.1. Configuration example of the rover

Click the ra io button of “Rover” to show the setting page as below picture.

7. Click the selection “Position Mo e”. There are three options. The option “kinematic” is

for RTK position. The option “Moving baseline” is for RTK hea ing. The option

“kinematic + moving baseline” is for simultaneous RTK position an RTK hea ing.

8. Click the selection of “Up ate Frequency” to set the up ate rate of RTK.

9. Input the settings of NTRIP Caster.

10. Click the button “Apply” to take effect. The settings will be save in the internal flash

memory.

11. Check 4G/LTE connection by clicking “Network” button. If the pro uct registers to the

network of the telecom provi er, it will show “Connecte ” as below picture.
