Ken,
Thanks for the response. I have been guided by the EQASCOM & AutoGuiding pdf published by EQMOD. The very last paragraph of which reads "For those using the EQMOD EASCOM driver the good news is that the Pulse Guiding implementation has been carefully designed to work alongside PEC. I would not however advise the use of PEC with ST-4 guiding for the Synta mounts."
Because of this I decided to use pulse guiding only with connection from the computer to the mount via Shoestring USB2-EQ5 cable.
Is the Lodestar capable of USB input/output from camera to computer and then to mount via EQMOD or is it ST-4 only via the auto guide port?

Cheers,
Frank
