5.7. Wakespeed WS500 alternator regulator support

5.7.1. Introduction

The WS500 is an external smart alternator regulator with CAN-bus and NMEA 2000 communication, which is especially
applicable in Marine and RV applications. The Wakespeed WS500 is supported by Venus OS and offers the possibility to monitor
the performance of your alternators via a GX device.

5.7.2. Requirements

Necessary requirements for the integration of the WS500 are:
1. VenusOS firmware v2.90 or higher installed on your GX device
2. Wakespeed WS500 firmware 2.5.0 or higher installed on the WS500 controller
3. The WS500 must connect to the VE.Can port of the GX device. It is not possible to monitor the WS500 when connected to
the BMS-Can port of a Cerbo GX.

5.7.3. Wiring the WS500 to VE.Can

Both, the WS500 and VE.Can, use RJ45 connectors for their CAN ports.
However, both have different pin outs. This means that a normal (straight UTP cable) network cable cannot be used. A crossover
cable is required. This crossover cable must be made by yourself. The following diagram reflect the pin out of the two devices.
The important pins to look at are pin 7 and pin 8 for CAN-H and CAN-L on the VE.Can side and pin 1 and 2 for Can-H and CAN-L
on the WS500 side.
Therefore a cable is needed where pin 1 and 2 on one side are connected to pin 7 and pin 8 on the other side. Pin 7 goes to pin 1
and pin 8 to pin 2.
The RJ45 connector with pin 7 and 8 on one end connects to the VE.Can port of the GX device. The other end of the cable with
pin 1 and 2 connects to the WS500 controller. Both sides must be terminated.
The cable colors do not matter for the do-it-yourself cable. Wakespeed also offers a ready-configured cable with a blue RJ45
connector on one end that must be connected to the VE.Can port.
Please note that the black terminators supplied by Wakespeed and the blue terminators supplied by Victron
are not interchangeable. Therefore: insert the Victron terminator on the Victron side of the network, and insert
the Wakespeed terminator into the Wakespeed.
