1.2 Typical application of TX204 Receiver

The following sections give three typical applications for TX204, draft config steps
are given, too. The detailed config can be found in the specific sections in chapter 5.

1.2.1 Work as a RTK client

The TX204, configured with a smartphone via the Wi-Fi, can work as a rover. The
steps are given below:

1. Insert the SIM card1, and an antenna is installed.

2. Power on the receiver, go to Network Settings -> Mobile network Settings to

check the network status. Please ensure the GPRS model status is ON, Auto Start
is Yes and Dialing status is OK.

3. Go to I/O Settings -> RTK client to set where the RTK corrections are from.

4. Go to Status-> Position to confirm the position type is fixed.

5. The position info can be output through the Bluetooth or the Ethernet port in the

adapter to transmit the solution to Internet or an App.

1.2.2 Work as a Base

The TX204 can also work as a base, from which RTK corrections can be transmitted
to Internet with an Ethernet port or to a radio. The steps are given below:

1. An antenna is installed.

2. If the RTK corrections are transmitted to a radio, no SIM card1 is needed,

otherwise, insert the SIM card1.

3. Power on the receiver, Go to Receiver Configuration-> Reference Station

Settings, and select Auto Base or Manual Base in the Reference Station Mode
menu.

4. If a SIM card is inserted, go to step 6.

9 / 49

5. Connect an adapter to TX204 and connect the COM1 (under the RJ-45 port) to a

computer, after the RTK corrections configuration is finished, disconnect the
COM1 to the computer and connect a proper radio to it.

6. Go to Network Settings -> Mobile network Settings to check the network status,

ensure the GPRS model status is ON, Auto Start is Yes and Dialing status is OK.

7. Go to I/O Settings -> TCP/UDP_Client1/Ntrip Server, select Connect in the

modify menu and ensure the RTK corrections are transmitted to the server.

1.2.3 Work as a post-process data collector

There is a 16GB flash in the TX204, it can be used as a data collector to save raw
measurements for post-processing. The steps are given below:

8. An antenna is installed.

9. Power on the receiver, go to Data recording -> Log settings, press Modify in the

Setting Parameter, after all the parameter is set, press ON in the Switch.
After all the data is saved, plug the adapter to TX204, and you can connect the USB
port in the adapter to your computer and copy/delete the files in the flash memory.

3 Battery and Power

Precis-TX204 uses a built-in rechargeable battery. The operational time provided by
the internal battery depends on the type of measurement and operating conditions.
Typically, the internal battery provides up to 12 hours operation.

3.1 External Power

Precis-TX204 can use an external power source for power supply.

3.2 Charging the Battery

Charge the battery completely before using it for the first time. To charge the battery,
you should plug the AC adapter in the DC port in the rear panel, and then plug the
other end of the AC adapter to a 220VAC or 110VAC outlet. During charging, one of
the five LEDs besides the battery button will blink to show the processing. All the
LEDs are off after charging is completed, which is about 4 hours.

Figure 10 Charging the battery

3.3 Removing the Battery

The built-in battery may be removed only by Tersus GNSS engineers.

automatically.
 Manual Base: The receiver will serve as Base after the restart, and then broadcast

RTK correctors based on the coordinates before power off.

For latitude and longitude

The coordinates of the receiver must be input if it work as a base, there are three
methods to enter the coordinates and shown as follows.

Figure 30 Coordinates input

 Acquire Current Position: Click this button to acquire current position obtained

through single-point positioning automatically.

 Manual Input: Manually input a known coordinates.
 From CORS: After logging in CORS, the receiver will obtain a coordinates based

on fix solution.

For sample for average

Users can determine the positioning limit and sampling amount. The positioning limit
falls into two types.
 Single Solution Coordinates: Collect the coordinates of receiver obtained through

single-point positioning.
 Fixed Solution Coordinates: Only collect coordinates of receiver based on fix

solution.

Check the charge on the external battery.
Check the charge on the internal battery.
Check that the Lemo connector is seated
correctly and that the cable is secured to the
receiver.
Check for broken or bent pins in the
connector.
Check that you are using the correct cable for
the connection between Lemo port and
external power supply.
Check that the correct external power supply
is connected to a particular Lemo port.
Check pinouts with a multimeter to ensure
internal wiring is intact.
Wait until the receiver display shows that
more than four satellites are being tracked.
Turn off the receiver and then turn it back on
again.

Check the port settings for the receiver by
using the Web interface. Check that the radio
ports are correctly set up.

Try a different cable.
Examine the ports for missing pins.
Use a multimeter to check pinouts.
If the radio has its own power supply, check
the charge and connections.
Make sure that the GNSS antenna cable is
tightly seated in the antenna connector on the
GNSS antenna.
Check the cable for any signs of damage. A
