ROBOTICS
TXT 4.0 CONTROLLER
fischertechnik TXT Operating manual_EN | 10. November 2021, 9:18 PM
5. 9V IN, DC port (3.45 mm, plus pole internal)
The power supply from the Power Set is connected here (not included in the scope of delivery).
6. 9V IN, Battery Pack connection
This connection allows for a mobile power supply via the fischertechnik Battery Pack (not included in the
scope of delivery) as an alternative to the power pack.
7. EXT connections for expansions
These connections can be used to link additional ROBOTICS TXT 4.0 Controllers, thereby expanding the
numbers of inputs and outputs. In addition, you receive an I2C interface, for instance for sensors.
8. Outputs M1– M4 or O1– O1
4 motors can be connected to the outputs. Alternatively, 8 LEDs or electromagnets with the second pole
connected to a ground connection ( ) can be used.
9. Inputs C1– C4
Fast counting inputs, record counting pulses up to 1 kHz
(1000 pulses / sec.), for instance from fischertechnik
encoder motors. These can also be used as digital inputs,
for instance for buttons.
10. 9V Out
Supplies sensors with the required operating voltage 9V+,
such as color sensors, track sensors, ultrasound sensors,
magnetic encoders.
11. On / off switch
Switches the Controller on or off, and indicates the
operating status via different colors.
12. Speaker
The speakers can be used to play sounds or noises stored on the Controller or the memory card.
13. Universal inputs I1– I8
These signal inputs are designed for all-around use. They can be set using the ROBO Pro Coding software
for:
›
Digital sensors (buttons, reed contacts, phototransistors) – Digital 5 kΩ
›
Infrared track sensors – Digital 10V
›
Analog sensors 0–5kΩ
(NTC resistors, photoresistors, potentiometers)
