Control your Spectrum ST4 motorized pan and tilt head using a Skaarhoj PTZ controller using this Network to Serial Adapter from eMotimo. The adapter allows you to connect a Skaarhoj PTZ controller via IP over a network and then it converts the control signals to serial.

The adapter features an RJ45 port that connects to your network and supports your network's DHCP server to set the IP address. Using the connected cable, it plugs into the ST4 using a 2.5mm TRS plug to relay the serial control commands to the head. A 5 VDC power adapter is included to plug in the adapter, and there are mounting holes on the adapter to mount it onto a wall or console.
