Here is a simple QHY5 guide port tester circuit . Maybe useful to test if your QHY5 guiding function works well.

The theory is : QHY5 use optic isolator, the common pin connect the GND, When guide command comes, QHY5 will pull down the level of the Guide port of EQ mount.
Most EQ mount is active when the guide port direction pin is pulled down.
