+===== 7. NEW Direct communication via BMS EX =====
+==== 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
+==== 1.2 A GX device is required, eg Color Control GX (CCGX), Venus GX (VGX), etc ====
+It is essential to use the CAN-bus connection of a [[venus-os:start|GX device]] with the SOLARMD batteries for the keep-alive signal, communication of charge and discharge limits, error codes and state of charge.
+When used with Solar MD batteries, the minimum required firmware version for the [[venus-os:start|GX device]] is v 2.15. Please use the latest firmware version on all connected devices, including CCGX/VGX, Inverter/Charger, and MPPTs. There are regular updates to improve performance and reliability.
+==== 1.3 All 48V Multis, MultiPlusses, MultiGrids and Quattros are compatible for SS074/SS4037/SS202 ====
+The minimum firmware version is 422. Though updating to the latest firmware is recommended where possible.
+These inverter/charger units must be connected to the [[venus-os:start|GX device]] via the VE. Bus connection port.
+In grid-connected systems, advanced control functions are configurable in the ESS settings on the [[venus-os:start|GX device]].
+In off-grid systems, the control functions of the SOLARMD Battery Management System (BMS) are built into the latest version of the [[venus-os:start|GX device]].
+==== 1.4 All 48V BlueSolar and SmartSolar MPPT Chargers are compatible ====
+For proper operation, the Battery battery needs to be able to control the charge current of the solar MPPTs. It is recommended to use the MPPTs with VE. Direct port with SOLARMD batteries.
+MPPTs with a VE.Direct port
