I use the SW Synscan wifi module. It plugs in to the handset port on the HEQ5 Pro mount and is powered from the mount. It can connect using an app on your laptop, iPad or smartphone and provides all of the handset functionality. You can either use your home wifi network, or if you are remote you can use the wifi hotspot provided by the module by setting your laptop, iPad or phone to detect the Synscan module wifi signal. One less cable!!
I should also add that it is recognised by EQMOD - there is a Synscan wifi driver, which means you can control via APT, planetarium software etc.
