BMV700 V.direct port feed two equipment's

Hello guys, I have a Katana catamaran with a CAPI2 monitoring system taking power information from a BMV700 rs232/V.direct cable, however he bought a VenusGX to control the MPPT and multi onboard, but would be good for the system to have a signal from the BMV, is there a way to multiplex V.direct signal?, I've heard something about the usb hub used to do that but tried and could not succed, can anyone help me here?

There might be simpler and less costly ways, but this device will split an RS232 signal in a safe isolated manner.
