Default Outdoor 4 pin connector pinout

My design is an outdoor LED array RDM fixture almost finished is goning to be produced soon
48VDC powered with single cable IP66 connector
4 pin : V+/V-/D+/D-

I know for XLR connectors standard pinout is :
1) COM
2) D-
3) D+

But I couldn't find standard pinout for circular 4 pin outdoor connectors like my design

is there any standard pinout of 4-pin connetors with DC power and RDM/DMX?

Otherwise I plan to assign pins as below :
1) V- (COM)
2) D-
3) D+
4) V+
