What You Need to Get Started
To set up and use your TBX-68, you need the following:
TBX-68 accessory kit(s)1
Compatible 68-pin DAQ device and device documentation
The correct cable(s) for your device
0.125 in. flathead screwdriver
12-30 AWG wire
Wire cutters
Wire insulation stripper
Getting Started with the TBX-68
Remove all cables from the TBX-68 before getting started. If you have not already installed
your DAQ device, refer to the installation guide that came with your DAQ device for
instructions. Complete the following steps to set up the TBX-68.
1. (Optional) Mount the TBX-68 to a standard 35 mm DIN rail using the attached clip on the
back of the accessory.
2. Connect the wires to the screw terminals by stripping 6 mm (0.25 in.) of insulation,
inserting the wires into the screw terminals, and securely tightening the screws with the
flathead screwdriver to a torque of 0.8 N · m (7 lb · in.). Refer to your device documentation
for the DAQ device pinout and signal information.
Caution Do not connect input voltages >30 Vrms/42 Vpk/60 VDC to the TBX-68.
The TBX-68 is not designed for any input voltages >30 Vrms/42 Vpk/60 VDC, even if
a user-installed voltage divider reduces the voltage to within the input range of the
DAQ device. Input voltages >30 Vrms/42 Vpk/60 VDC can damage the TBX-68, all
devices connected to it, and the host computer.
Caution Do not use for measurements within Categories II, III, or IV.
3. Connect the TBX-68(s) to the DAQ device using the appropriate cable(s) for your device.
4. Launch Measurement & Automation Explorer (MAX). In the left panel, expand Devices
and Interfaces to confirm that your DAQ device is recognized, and then configure your
device settings.
5. Test specific device functionality. Run a Test Panel in MAX by right-clicking your DAQ
device and selecting Test Panels. Click Start to test the device functions.
When you have finished using the TBX-68, power off any external signals connected to the
TBX-68 before you power off your computer.
1 You can use up to two TBX-68 accessories with M/X Series devices with two connectors.
