Installation ===== The side labeled 'CAN-bus BMS' plugs into the battery. The other side, labeled 'VE.Can' must be plugged into either the VE.Can port of the GX device, or the BMS-Can port. Both port types (VE.Can and BMS-Can) on a GX Device can be configured for use with a CAN-bus BMS connected third party battery. For configuration, see the manual specific to the brand of battery you are using. ===== 3. Pin-out ===== In some cases it might be needed to make the cable at the location. Find below the pin-outs. Make sure to very carefully test the cable after crimping it. Self-made cables are very often the causes of very hard to diagnose problems. ==== 3.1 Type A ==== ^ Function ^ Victron VE.Can side ^ Battery side ^ | GND | Pin 3 | Pin 6 | | CAN-L | Pin 8 | Pin 5 | | CAN-H | Pin 7 | Pin 4 | ==== 3.2 Type B ==== ^ Function ^ Victron VE.Can side ^ Battery side ^ | GND | Pin 3 | Pin 2 | | CAN-L | Pin 8 | Pin 5 | | CAN-H | Pin 7 | Pin 4 |
