 ## Configure the binding
 
-Configure the binding specifying in the JSON configuration file the CAN device\(s\) that it will to connect to. Edit file _/var/lib/afm/applications/low-can-binding/0.1/can\_buses.json_ and change the CAN device name to the one you will use :
+The binding reads system configuration file _/etc/dev-mapping.conf_ at start to map logical name from signals described in JSON file to linux devices name initialized by the system.
+Edit file _/etc/dev-mappping.conf_ and add mapping in section `CANbus-mapping` :
 
 Using virtual CAN device as described in the previous chapter:
-```json
-{
-    "canbus":  "vcan0"
-}
+```ini
+[CANbus-mapping]
+hs="vcan0"
+ls="vcan1"
 ```
 
 Using real CAN device, this example assume CAN bus traffic will be on can0.
-```json
-{
-    "canbus":  "can0"
-}
+```ini
+[CANbus-mapping]
+hs="can0"
+ls="can1"
 ```
 
 On a Porter board there is an embedded CAN device so `can0` already exists.
 
 So you might want to use your USB CAN adapter plugged to the OBD2 connector, in this case use `can1`:
-```json
-{
-    "canbus":  "can1"
-}
-```
-
-If you have several specify CAN bus devices use an array:
-
-```json
-{
-    "canbus": [ "can0", "can1" ]
-}
+```ini
+[CANbus-mapping]
+hs="can1"
 ```
 
-> **CAUTION VERY IMPORTANT:** Make sure the CAN bus\(es\) you specify in your configuration file match those specified in your generated source file with the [can-config-generator](http://github.com/iotbzh/can-config-generator).

 ## Run it, test it, use it !
 
 You can run the binding using **afm-util** tool, here is the classic way to go :
 
 ```bash
