MPPT-150/85 not communicating with Venus GX

<p>I just bought a Venus GX and connected it to my 6 year old MPPT-150/85 using the CAN.BUS RJ-45 connector as shown on the Venus diagram., The Venus doesn't see the MPPT despite variations of terminator/no terminator and various port configurations I've seen on this forum.</p><p>What protocol/baud rate should I be using, or is the MPPT too old?</p><p>If the MPPT is too old can a BMV-7xx be configured to appear as a solar charger if connected in the MPPT's battery line?<p>

Hi @Maitland

there is only one terminator option: one at both ends.
