You must enter the correct values for all antenna-related fields since the choices will affect the accuracy for logged data and broadcast RTK corrections significantly. 4.3.2 Reference Station Settings Reference station has three modes: Auto Rover, Auto Base and Manual Base : Auto Rover mode Set receiver as rover after restart. Auto Base mode Set receiver as base automatically after restart. Manual Base mode Set receiver as base after restart, the position is input manually or is got from averaging positions. Reference Latitude and Reference Longitude: The coordinates of the receiver must be input if it s working as a base, there are three methods to enter the coordinates and shown as follows. Acquire Current Position: Click this button to acquire current position obtained through single-point positioning automatically. Sample for Average: The position will be got from averaging solutions. 4.3.3 Receiver reset Use this page to completely or partially reset the receiver. 23 / 30

4.3.4 Languages Use this page to select the web interface language. 4.4 Data recording Use the Data Recording menu to configure the receiver to collect static GNSS data and to view the logging settings. You can configure settings such as raw measurements rate, recording rate, continuous logging limit, and whether to auto delete old files if memory is full. This menu also provides the controlling for the FTP push feature. 4.5 Input and Output stream settings I/O settings must be configured when a SIM card is working or Ethernet has connected. 4.5.1. RTK Client In this mode, receiver can be connected to TCP or NTRIP when it set as rover. Or set the receiver as base/rover to transmit/receive data from TERSUS stream platform. 4.5.2. TCP/UDP_Client/NTRIP Server This mode includes TCP server, UDP client and NTRIP server. In all the modes, receiver can send NMEA0183, RTCM, CMR, ephemeris and raw data to a specified address. Generally, it s used to send RTCM data to a NTRIP caster when TX204 is configure as a base. 4.5.3. TCP Server/NTRIP Caster This mode include TCP server and NTRIP caster functions. In these modes, TX204 can transmit NMEA0183, RTCM, CMR, ephemeris and raw data to the Ethernet port (a public IP address is needed for the Ethernet port). Other TX204 receivers can receive data from the IP/port. 24 / 30

6. Typical Application of TX204 6.1 Working as a RTK rover The TX204, configured with a smartphone or a computer via the Wi-Fi, can work as a rover. The steps are given below: 1) An antenna is installed; insert a SIM card 1 in the TX204. 2) Power on the receiver, after dozens of seconds, the GPRS Status LED on the front panel will blink, please wait until it s solid ON, see Table 2. 3) Go to Receiver Configuration-> Reference Station Settings, and select Auto rover. 4) Go to I/O Settings -> I/O Settings -> RTK client to set where the RTK corrections are from. If the corrections are from a NTRIP caster, then the caster s IP, the mount point, the user name and password must be input. The download communication LED will blink when RTK corrections are receiving. 5) Go to Status-> Position to confirm the position type is fixed. 6) If position information wanted to be output to the Bluetooth, go to I/O Settings -> I/O Settings ->Bluetooth, in the NMEA logging, select GGA to be output at 1Hz, press confirm to enter the parameters. The upload communication LED will blink. 6.2 Working as a Base 2 The TX204 can also work as a base, from which RTK corrections can be transmitted to Internet with an Ethernet port. The steps are given below: 1) An antenna is installed; insert a SIM card 1 in the TX204. 2) Power on the receiver, Go to Receiver Configuration-> Reference Station Settings, and select Auto Base or Manual Base in the Reference Station Mode menu. If Manual Base is selected, input the position of the base. 28 / 30

3) Wait until the GPRS Status LED on the front panel is solid ON, see Table 2. 4) Go to I/O Settings -> I/O Settings -> TCP/UDP_Client1/Ntrip Server1, select NTRIP for Connection protocol, input the server IP, port, password and mount point, then press Confirm. The upload communication LED blink. will 6.3 Working as a static data collector There is a 32GB flash in the TX204, which can be used as a data logger to save raw measurements for post-processing. The steps are given below: 1) An antenna is installed and connected to TX204. 2) Power on the receiver, go to Data recording -> Log settings, press Modify at the right of record1 item to configure all the parameters, then press ON in the Switch. 3) After data collection is finished, press OFF in the Switch. 4) Keep TX204 power on, and connect an adapter to the TX204, and you can connect the USB port in the adapter to your computer and copy/delete the saved files in the record_1 directory.
