Mesa 7i95t rs485 spindle

Hey chaps.

With the mesa 7i95t 7i95t_1pktv2d.bin firmware what pins are needed for rs485 spindle? Any resisters needed? I want to use the HY_vfd component to drive my vfd.

Or is a rs485 usb easier to setup? 

Thanks in advance 

The PktUART interface is the second serial interface on TB4 pins 19..24
I don't think it needs resistors on the latest board revision, but I would
need to check that tomorrow.

If you want to use the HY_vfd component, you need to use s USB or serial
port to RS-485 adapter.
