# How do I set terminating resistors and program CAN offset on Flex™ from the SmartPlex app?
## Learn how to enable or disable terminating resistors and program the CAN offset for your Flex Monitor using the TFT SmartPlex App. These settings help ensure proper communication with your truck’s electrical system or installation configuration.
The TFT SmartPlex App gives you access to critical configuration options like toggling terminating resistors and setting the CAN offset for your Flex Monitor. These adjustments are essential for integration with your truck’s electrical or installation system.
### Step-by-Step Instructions
1. Open the Monitor Hub
- Ensure your Flex Monitor is connected.
- From the app’s home interface, tap into the Monitor Hub.
2. Enter Program Monitor
- Select Program Monitor to access advanced configuration settings.
3. Enable or Disable Terminating Resistors
- Scroll down to the field labeled Terminating Resistor Enabled.
- Tap to toggle the setting on or off depending on your system’s requirements.
4. Set the CAN Offset
- Scroll further down and find the CAN Offset field.
- Tap the field, input your desired CAN offset value, and confirm the setting.
### Why It Matters:
- Terminating resistors help maintain proper signal integrity on the CAN network.
- The CAN offset ensures that communication is aligned with your vehicle or installation system's specifications.
