Can I manually invert or convert an I2S connection

I modified my Oppo 203 with an I2S board from Jaehong Lee of OppoMods. It works perfectly with SMSL Dacs which follow PS audio format for I2S. But it doesn't work with Gustard Dacs which have the I2S-H output. Is there a converter or a cord that will allow me to play a PS style I2s from my Oppo 203 to a Gustards X18 which has the  I2s-H?

Thankyou
