# CANBUS Bitrate Switching
## Do You Need To Switch Bitrate?
Are you running CANBUS at a different bitrate? If you arent using the default 1M (1000000) go ahead and use the steps below to swap to whatever version you need.
***
## Step 1. Plug In Cartographer via CANBUS
## Step 2. SSH Into Your Host Device & Run The Script
```bash
cd ~
if [ -d ~/cartographer_firmware/ ]; then
echo "Directory Exists - Starting Firmware Script"
cd ~/cartographer_firmware/
git pull
else
git clone https://github.com/Cartographer3D/cartographer_firmware.git
fi
~/cartographer_firmware/scripts/firmware.py
```
## Step 3. Find Your Device
## Step 4. Select Which Firmware/Bitrate You Want
## Step 5. Flash Firmware
## Step 6. Re-Run Script
```bash
cd ~/cartographer_firmware/scripts
./firmware.py -f can
```
## Step 7. Find Your Device
## Step 8. Select Firmware & Flash
## Step 9. Done
