;Calex Charger Connections
: AC input is an IEC-60320 C13 inlet.
: DC output is an [[Anderson_connector|Anderson]] [http://www.andersonpower.com/us/en/products/sbs/sbs-50.aspx SBS50-BRN], but it seems to be a narrower pin pitch with no center data pin set.
: CANbus signal interface is a JAE MX23A18NF1 connector (applies to the Calex, not the Mean Wells!)

;CANbus wiring
:Adapted from an examination of the wiring on a 2014 SR: [http://electricmotorcycleforum.com/boards/index.php?topic=6167 Onboard charger wiring for 2014 and 2015+] for the Calex.
:When the onboard charger is plugged in and powered on the onboard charger pushes:
:* 5V and 48mA through the Charger attached Pin #11.
:* 5V and 26mA through the Charger enabled Pin #12.
:The 5V ground reference is Pin #13 which is battery negative.
:With this knowledge, another onboard charger solution can be wired to function as follows:
:# Run a separate circuit that when triggered pushes 5V ~50mA through pin#11 (attached charger) with the other end of the 5V circuit connected to the battery negative pin #13.
:# When this is triggered, the bike shows the battery state of charge % and charge time remaining, closes the contactor and allows charging - through the accessory charging port, the onboard charger port or via the Sevcon battery terminals for high power charging.
:# Upon completion of charging, the 5V can be switched off and the charge level and time remaining switch off and the contactor opens just as with the onboard charger.
:# The bike can be keyed on and ridden away as normal.
: Using this method there is no need to leave the bike on when charging via the accessory charging port or the controller battery-side cables, or if you are using the [[#Accessory_Charging_Port|accessory charging port]] without triggering the auxiliary pin on the accessory charging port's Anderson SBS75XBRN.
:;NOTE
:: For 2015 onwards, the charger install uses additional wiring which may have a different approach using CAN signals, so it may require a different approach.
