ST4 to Pulse Guiding

Daviswh

I’ve made a change to my rig, hopefully a positive change, from ST4 to EQ Direct direct cable (USB2EQ5 Pulse Guiding?), I’m not sure what term to use for ST4 guiding.
I have an ASIAIR Plus, HEQ5, 120mm guide camera and Red Cat51.
What differences, if any, can expect from ST4 to Pulse Guiding?
The EQDir cable is connected fro the Asiair Plus to the HEQ. ZHand Coller port.
Thanks for any advice.

If you use ST4，you must choost the mount name is ST4-on-camera, and you need goto some target first.becaues the ST4-on-camera can not slew the mount.
