Installation
Hardware
To install the TravelBus, connect it to the PC using the USB 3.0 cable
provided in the kit.
Software
To install the software, follow these steps:
- Download the software from https://www.acute.com.tw/logic-analyzer-en/support/download/software
- Run TBA.exe and choose either Protocol Analyzer or Logic Analyzer from the menu window below.
- To open an old file (.TBW), click on Open File…
Operations
Protocol Analyzer
Main Window
- The toolbar includes options for Protocol, Waveform, Run, Search, and Save to text with .csv or .txt format.
- The Report Window displays real-time protocol data.
- The Waveform displays the waveforms only when the Waveform option is checked.
- The Status Bar shows if the TravelBus is connected to the PC, the protocol being used, time captured/available time to capture, etc.
- The Detail/Navigator/Filter shows the protocol data detail and is able to filter those data.
- The Cursors display the time/frequency difference between cursors.
To select I2C protocol, follow these steps:
- Click on Protocol Select.
- Choose I2C from the options.
- Choose either I2C ports or LA ports (channel 0~15) to measurethe I2C signal. The I2C ports are only for low-speed I2C signals.
- The TravelBus auto-detects the signal frequency and displays the real-time waveform.
- Choose the address mode from the Options menu.
- The threshold is provided by default for each protocol or can be set manually from the Threshold option.
If the I2C Port is selected, the SDA and SCL channels are I2C ports for slow I2C signals.
PWM
PWM decode can show at most six PWM curves on the screen. The direction can be determined by Direction Message on Direction channel. It can be chosen as High or Low to represent the positive direction, and the example of practical application is the positive or negative rotation of the motor. You may choose one of the three curves, duty-cycle, frequency and RPM.

There are two methods for hardware wiring:
TravelBus is the Master, while the oscilloscope is the Slave.
Wiring direction is from TravelBusTravelBus’s Trig-Out the oscilloscope’s
Trig-In (see Figure 1)
In Figure 1, the USB or Ethernet (TCP / IP) interface is connected to the computer, and then connect the BNC MCX cable to the TravelBus Trig Out and the trigger input interface (Ext Trig, Aux In or Trig In) of the oscilloscope. MDO4000 series is fixed in the analog channel CH4.
The oscilloscope is the Master, while the TravelBus is the Slave.
Wiring direction is from the oscilloscope’s Trig-Out TravelBusTravelBus’s
Trig-In (see Figure 2).
In Figure 2, the BNC MCX cable is connected to the TravelBus Trig In and the trigger output interface (Trig Out) of the oscilloscope. After completing the above actions, press the “Stack Oscilloscope” button, as shown below:
Select the DSO
Select the brand that needs to be stacked on the oscilloscope. When there is
no DSO hardware available for stacking, emulation is the mode used to read
back the storage files of DSO stack.
Connection Type
It can be used to select USB, TCP / IP, according to the connection interface
provided by the oscilloscope brands.
Connect IP
It can be used to select TCP / IP for the connection mode and enter IP
address. When the Ethernet crossover cable is used, it is recommended that the
IP settings of the two machines be 192.168.1.2 and 192.168.1.3 respectively.
Gateway is the same, set to 192.168.1.1, and DHCP is set to OFF. If the IP
setting does not take effect, please disable and then enable the network, or
reboot to make the network settings effective.
Screen of oscilloscope stack
Oscilloscope is set as the master, while the TravelBus is set as the
slave
If the stack is composed of the oscilloscope as the master and TravelBus as
the slave, you must not only complete the above-mentioned basic settings but
also set the external trigger signal. For the hardware wiring, please refer to
Figure 2. Press “Trigger Condition” → “External Trigger”, as shown below.
Stack Delay
When TravelBus is triggered successfully, the Trig-Out signal is transmitted
through Cable to the DSO with a time delay, resulting in a deviation between
the logic and the analog signal time displayed by the waveforms. Therefore,
the stack delay time must be set to compensate the delay. In the waveform
display screen, you can put the mouse on the top of the DSO waveforms, hold
down the Shift key, and then use the mouse’s left button to drag the DSO
waveforms to the appropriate location to complete the stack delay correction.
Test Connection / Connection Status
It can be used to connect the oscilloscope / display the current stack
oscilloscope model and automatically add the oscilloscope channel to the
waveform window.
Dedicated Channel Description
I2C、DP AUX port are supported on the TB2000/TB3000 series
There are additional RS422 / 485、CAN / CAN-FD port supported on the TB2016B/TB3016B,
(DP AUX, RS485, CAN / CAN-FD are differential signal. Since TB2000/TB3000 series have the converter inside, there is no need to set the threshold before measure)
Protocol Analyzer mode
Please modify the channel settings in the Protocol Setting.
Logic Analyzer mode
Use Quick Setting to change channel settings. Warning: Don’t change the
trigger type after quick setting, or the dedicated channel can’t not use.
(If the I2C port is on, only the I2C Clause Trigger can use. If change to the other trigger mode, the I2C port can’t use. Unless re-Quick Setting.)
