 ===== CAN Bus Wiring =====
-The connection of the Lite to the GX-device is extremely simple. A standard **straight through** CAT5e Ethernet cable is required of the desired length, with one end plugged into one of the RJ45 sockets on the Lite and the other end plugged into one of the CAN sockets on the GX-device. Note that the second RJ45 socket in each case must be fitted with an end of line 120Ω resistor. Two are supplied with each GX-device.

 **Note:** In the case of the Venus GX or Octo GX, if the VE.CAN ports (RJ45) are being used by MPPTs, the secondary CAN bus needs to be connected using the green terminal blocks.  If you require any information on how to do this, contact Freedom Won support at support@freedomwon.co.za
+**Note:** When using a Cerbo GX use the 'BMS-CAN' port for the battery and configure that port to 500kpbs, the Cerbo GX has RJ45 ports for both CANbus channels.
 If multiple batteries are installed in parallel the second RJ45 socket is used to link the next battery in the line onto the CAN Bus network. The termination resistor is installed in the last battery in the CAN Bus line. Refer to Lite installation manual for further information.

 ===== Victron VE.CAN MPPTs and Freedom Won Batteries =====
-**Note:** In this section, the reference to "Color Control GX" refers only to that specific model of GX device and excludes the rest of the range.  The limitations described in this section apply only to the Color Control GX (CCGX).
+**Note:** In this section, the reference to "Color Control GX" refers only to that specific model of GX device and excludes the rest of the range.  The limitations described in this section apply only to the Color Control GX (CCGX), for these reasons it is recommended to use the Cerbo GX instead.
 The Freedom Won Battery Management System is configured by default to communicate over CAN bus at a 500kbps baud rate. For systems using a Color Control GX and Victron VE.CAN MPPTs, it is possible to change the baud rate of the battery to 250kbps in order to accommodate the VE.CAN baud rate. **However**, that is only possible with one battery on a system with a CCGX.

+All other GX devices have dual CAN-ports or a CAN-port that only supports 500kbit/s (GX version of inverters) so on those systems BMS-CAN should be set at 500kbps//
