*Before starting, follow the Installation and Start-up guide

1. Required elements

• 2x wires for CAN connection

MPU Toolkit

*Check if your GSR has a sticker indicating that the end of bus resistors are deactivated. If yes, go to the step 2. Connection.

!If your GSR does not have the sticker, check the resistance value with a tester. When the resistors are activated, the value is 120Ω. The following steps describes how to deactivate the resistors before going to step 2. Connection.

1. Remove the 6 screws from the base and sides

2. Slide the cover until it is removed from the GSR

3. Remove the FXS-CAN board pulling gently and equally on both sides

4. Turn around and check that the jumpers are on

5. Remove the jumpers to deactivate the resistors

6. Place the FXS-CAN gently, confirming that all pins are aligned correctly

7. Reverse the steps to re-assemble the GSR

2. Connection

1. Locate connector XMCBUS.

2. Locate CAN connectors on GSR.

3. Connect as described:
