# OnStation & TransTech Systems Integration FAQs
## Frequently asked questions about the integration
### **General**
#### **Q: What is the OnStation & TransTech Systems integration?**
The integration connects TransTech's PQI 380 and PQI 380+ non-nuclear asphalt density gauges with OnStation's digital stationing platform. This allows for seamless transfer of compaction data, enhancing project accuracy and efficiency.
#### **Q: What do I need to set up the integration?**
- An active TransTech Connect subscription.
- A compatible device: PQI 380 or PQI 380+.
- A minimum of 1 OnStation data license to view/export data out.
- A purchase of the integration.
#### **Q: Can OnStation support set up the integration for me?**
Due to SOC compliance, certain steps must be performed by the customer. However, OnStation support can guide you through the process via Teams or screen sharing.
#### **Q: Should I share my ClientID with others?**
No. Your ClientID is sensitive information and should not be shared externally to maintain security protocols.
### **Device Compatibility and Usage**
#### **Q: Which devices are compatible with the integration?**
Both the PQI 380 and PQI 380+ are compatible.
#### **Q: What's the difference between PQI 380 and PQI 380+?**
- **PQI 380**: Allows data export via USB. Measurements are saved as CSV files, which can be uploaded to TransTech Connect and then synced with OnStation.
- **PQI 380+**: Features instant data transfer. After taking a measurement, a QR code appears on the gauge. Scanning this code with the TransTech Connect mobile app automatically uploads the data, which can then be synced with OnStation.
### **PQI 380 Device**
#### **Q: How long will the PQI 380 last on a full charge?**
8–10 hours, depending on usage.
#### **Q: When should I charge my PQI 380?**
When the voltage indicator on the status bar reads 6.5 volts. It’s also a good idea to charge the PQI 380 at the end of the workday.
#### **Q: How long does it take to recharge the PQI 380?**
Approximately 4 hours.
#### **Q: Will the PQI 380 operate while charging?**
No, the device cannot be used while charging. However, an external battery charger and second battery pack are available.
#### **Q: How will I know when the PQI 380 is fully charged?**
When the LED indicator on the back of the gauge turns from red to green.
#### **Q: Should the PQI 380 remain in its original shipped case?**
Yes. Each case includes a standardization plate that is unique to that specific gauge.
#### **Q: Is it necessary to calibrate the PQI 380 annually?**
Yes, TransTech recommends annual calibration.
#### **Q: Is the PQI 380 case waterproof?**
Yes.
#### **Q: Can the PQI 380 be used to measure core samples from a job site?**
No.
### **Data Management**
#### **Q: How do I sync data from TransTech Connect to OnStation?**
- For PQI 380: Upload the CSV file to TransTech Connect, then manually sync the data to OnStation.
- For PQI 380+: After scanning the QR code, data is automatically uploaded to TransTech Connect. From there, it can be synced with OnStation.

1. Log into the OnStation Portal at [portal.onstationapp.com](https://portal.onstationapp.com/).
2. Navigate to **Integrations \> API Enabled Projects**.
3. Click on **Add Project** to enable OnStation projects to receive data from TransTech Connect.
#### **Q: Can OnStation support assist with project linking?**
Yes. OnStation admins can assist with project linking if provided with a written list of the projects to be associated. Contact support via email, support ticket, or text at 216-503-8554.
### **Troubleshooting**
#### **Q: I don't see the "Configure OnStation Integration" option in TransTech Connect. What should I do?**
If this option isn't visible, contact your TransTech representative to ensure your subscription includes integration capabilities.
#### **Q: My data isn't appearing in OnStation after syncing. What could be the issue?**
Ensure that:
- The API key has access to the desired projects in TransTech Connect.
- The projects are correctly linked in the OnStation Portal.
