 This parameters page is also a good place to check that all batteries are connected and working properly. In normal working conditions, for the SS4037 (3.7 model), the current limit is 100A per module. For example, 140A charge current limit (400 / 100 = 4) means there are 4 SOLARMD battery Batteries connected.  This parameters page is also a good place to check that all batteries are connected and working properly.

-Color Control GX Configuration 
-The CCGX only has one available VE.Can port. It is not possible to connect both CAN products such as VE.Can MPPT (250 kbit/s) and an Battery battery CAN-bus (500 kbit/s) together on the CCGX. As the SOLARMD Battery MUST be connected, you will need to use the port for that. This will mean no data is collected from the VE.Can MPPT, nor can the CCGX control it. This means you are required to use the “Allow to Charge” wire configuration for the MPPT. 
  
-Venus GX Configuration +=== Color Control GX Configuration === 
-The VGX has two CAN-bus interfaces available. The VE.Can MPPT will remain connected to the VE.Can port, while the SOLARMD CAN-bus cable should use the specific CAN-bus connections (H, L, GND). This allows data from the MPPT and SOLARMD battery simultaneously. You will only need to connect the Allow-to-charge wires if using the VE.Can MPPT and VGX. + 
-The CAN-bus connections are galvanically isolated at the SOLARMD LOGGER V2. There is no issues using the non-isolated connection of the VGX. +The CCGX only has one available VE.Can port.

 + 
 +==== 7.1 Communication Cable Connection ==== 
 + 
 +It is recommended that CAT5e cable be used. The termination resistor on the last battery should be ON, the rest should be OFF. Please use between all batteries CAN2 and CAN1 straight cable connection. For the last battery to the GX device[[battery_compatibility:can-bus_bms-cable| Type B]] cable connection is required. 
 + 
 +The minimum firmware version of the BMS EX should be v 178

 +==== 7.2 A Battery settings ====  
 +Refer to the BMS of LoggerV manual to configure the CANBUS 2 interface for a Victron device. Note: After changing CANBUS 2 settings on the battery, the Victron GX device will need to be rebooted.
