External equipment
The BMS Main 3X / BMS Main 2RX device supports joint operation with vehicle controllers.
BKM controller
Communication parameters for the BKM controller are configured in the section "External equipment - BKM controller":

In this section:
- Enable – a flag to enable communication with the BKM controller;
- CAN port – port which is used to communicate with the charger:
- CAN1 (ext);
- CAN2 (int);
- Receive timeout – a timeout for receiving packets from the controller (if no data is received from the BKM controller during this time, then the communication loss flag is set), ms;
- Maximum voltage – a maximum charge voltage, V;
- Maximum current – a maximum charge current, A;
- SOC of the partially charger battery – a charge level of the partially charged battery, %;
- SOC of the fully charger battery – a charge level of the fully charged battery, %.
Basic J1939 vehicle
The basic vehicle protocol J1939 is developed by Movicom Electric, and its description is available upon request. Using this protocol, information about the parameters of the modular battery can be obtained. The protocol also implements the management of battery operation modes.
Communication parameters via the Basic J1939 protocol are configured in the “External equipment – Basic J1939 vehicle” section:

In this section:
- Enable – a flag to enable communication using the protocol;
- CAN port – port which is used to communicate with the vehicle:
- CAN1 (ext);
- CAN2 (int);
- BMS message ID – an identifier of the first message of the device in the J1939 network;
- Vehicle Message ID – an identifier of the first message of the vehicle in the J1939 network.
Evocargo vehicle
Communication parameters for the Evocargo vehicle are configured in the section "External equipment – Evocargo vehicle":

In this section:
- Enable – a flag to enable communication with the Evocargo vehicle;
- CAN port – port which is used to communicate with the vehicle:
- CAN1 (ext);
- CAN2 (int);
- Minimum voltage – minimum battery voltage, V;
- Maximum voltage – maximum battery voltage, V.
BMS IMD
To change communication parameters with an insulation monitoring device BMS IMD, select the "External equipment → BMD IMD " section:
In this section:
- Enable – a flag to enable communication with the IMD;
