| footnote 22 | The digital inputs on the Ekrano GX, Cerbo GX MK2 and Venus GX can also be used for pulse counting. The digital inputs on the Cerbo GX and other devices are not able to do pulse counting. |
| footnote 26 (application note) | The Cerbo GX MK2 revision is most valuable for some very specific applications. Such as the RV market in the US where a Lynx Smart BMS is installed, requires a VE.Can connection, as well as an RV-C port is required. And VE.Can and RV-C can not run on the same CAN network. Also for marine installations it offers an advantage when integrated into the NMEA2000 network, due to the VE.Can 1 port being galvanically isolated. |
| footnote 26 (differences vs first generation Cerbo GX) | It has the same enclosure and almost the same electronics design; except for (A) two fully functional CAN bus ports, called VE.Can 1 and VE.Can 2. Instead of one VE.Can and one dedicated BMS-Can port. And on the MK2 model, VE.Can 1 is isolated. On previous models, there was no isolated canbus port. All VE.Can ports can be configured to multiple profiles, including BMS-Can. (B) the RJ-45 sockets have been rotated 180 degrees, so its easier to take the cables out. (C) All three USB ports are fully functional. Instead of two functional and one for power, to a GX Touch, only. (D) Digital inputs can do pulse counting. |
