The Ethernet to RS-232 and 422 Interface is a device that converts OpenSoundControl messages to RS-232 and RS-422 serial messages. This interface is actually used to control an Animatics SM3430D Smart Motor and a Sony EVI-D70 pan-tilt camera (Visca protocol). An input is provided to accomodate a 5 VDC limit switch and the box also outputs continuous 12 VDC. It is based on the Rabbit 3700 microcontroller.
