1. Introduction
This chapter mainly introduces the overview and specification of the Tersus
Radio RS400H3.
1.1 Overview
The Tersus Radio RS400H3 is a base radio solution for wireless applications.
It provides reliable data communications for mission-critical applications where
a combination of stability, superior performance and long range are required.
The RS400H3 provides high speed, high power, wireless data links and has
been designed to survive the rigors of GNSS/RTK surveying and precise
positioning applications. Up to 28W transmit power maximizes range and
supports operation in difficult urban areas. The RS400H3 is equipped with
OLED display and keypads which are used for checking the operating status,
changing the operating channel, and transmitting power level.

1.3 Accessories
When using Radio RS400H3 to set up a base with Oscar GNSS receiver, a
high gain radio antenna and a telescopic pole are needed which are shown as
below.

2. General Operation
2.1 Basic Operation
The basic operations include buttons, indicator status and device menu.
1) Buttons
There are five buttons on the radio RS400H3. The following table shows the
detailed description of these buttons.
Table 2.1 Buttons description of radio RS400H3
Icon
Button
Function
Power
It is used to control radio power-on and power-off, with specific
functions as follows:
Short press the power button for about 1 second to power on,
the green power indicator light illuminates when successful
power-on (under normal power supply).
While power-on, long press the power button for 3 seconds to
power off, the power indicator light turns off and the display is
off.
Parameter confirmation in the menu.
Left
Switch over various functions in the menu.
Right
Up
Select corresponding item in the current menu.
Down
2) Indicator status
Normal power on/off of the radio has memory function, abnormal power on/off
does not have memory function. The detailed functions are as follows.

User Manual for Tersus Radio RS400H3 v2.0
13
In the case of abnormal shutdown for the last time, power on again after
outage, the radio powers on automatically;
In the case of normal shutdown for the last time, short press the power
button about 1 second to power on the radio;
If the voltage is lower than the under-voltage threshold value (11.0V by
default, depending on the user’s actual setting value), the red power
indicator light flickers twice in one second;
If the voltage is lower than the forbidden threshold value (10.2V by default,
depending on the user’s actual setting value), the red power indicator light
flickers once in one second;
If the voltage is higher than the under-voltage threshold value (11.0V by
default, depending on the user’s actual setting value), the green power
indicator light illuminates constantly;
When the voltage alarm appears, if it is under-voltage alarm, it is needed
to add 0.3V based on the under-voltage threshold value to resume to the
normal operating voltage (the green power indicator light illuminates
constantly);
Note:
Abnormal shutdown means not powering off by long pressing the power
button, for example, directly disconnecting power;
Normal shutdown refers to power off by long pressing the power button.
3) Device menu
The device menu is divided into two categories: basic radio parameter menu
and other features/functions menu.
Device information

serial number are displayed.
Channel and frequency
Under this menu, you can set up the current transmitting/receiving frequency,
select required communication frequency through up and down buttons, and
press the power key to select this frequency as the current communication
frequency, the star character “*” will appear after selection.
Data protocol
Under this menu, you can set up the current communication protocols such as
TRANSEOT, TRIMTALK and TRIMMK3. Select required communication
protocol through up and down buttons, and press the power key to select this
protocol as the current communication protocol, the star character “*” will
appear after selection.

Note: After changing the protocol, you need reselect the air baud rate
supported by the current protocol in the menu of “wireless link rate”.
Air baud rate
Under this menu, you can set up the current communication air baud rate.
Different protocols support different types of air baud rates. For example,
TRANSEOT supports 4800 and 9600 bps, while TRIMMK3 supports 19200bps.
Select required air baud rate through up and down buttons, and press the
power button to select this air baud rate as the current communication air baud
rate, the star character “*” will appear after selection.
Transmit power
Under this menu, you can set up the current wireless transmitting power level.
Currently three levels of power, high, medium and low, are supported. These
three levels of power values can be customized according to the demands of
users. Select required transmitting power through up and down buttons, and

press the power button to select this transmitting power as the current
communication transmitting power, the star character “*” will appear after
selection.
Figure 2.5 Transmit power
Serial baud rate
Under this menu, you can set up the current serial port communication baud
rate. Currently it supports following baud rates: 9600, 19200, 38400, 57600,
and 115200 bps. Select required serial port communication baud rate through
up and down buttons, and press the power button to select this serial port
communication baud rate as the serial port baud rate of the current
communication, the star character “*” will appear after selection.
Serial baud rate self-adaption
Under this menu, there are two options: self-adaptive master switch and
triggering enabling. The former has memory function, if turning on the switch,
ON is displayed on the menu; if off, then OFF is displayed. Self-adaptive
Figure 2.6 Serial baud rate

triggering enabling does not have memory function, the system remains in the
power up status after power-on; only if the self-adaptive master switch has
been turned on can the adaptive function of serial port baud rate work
normally.
If the serial port baud rate is successfully self-adaptive, a message box pops
up indicating successful self-adaptive matching, meanwhile, self-adaptive
triggering enabling stops automatically. If the serial port baud rate is not
successfully self-adaptive, this function is always operating.
Figure 2.7 Serial baud rate self-adaption
OLED sleep mode
Only if the “Function” is switched to “On” can the OLED display enter the sleep
mode. Sleep time has the following levels: 1min, 5min, 10min, 15min, 20min,
25min, and 30min.
Note: After the OLED display enters sleep, it can be waken up through button
and pop-up message.
