Analog Control Input Wiring
The following illustrations show the connection of either a 10k ohm linear potentiometer, a mechanical rotary encoder or
switches to one of the 8 analog control inputs of Control I/O. (Please see the SymNet Designer online help for information on
how to assign an analog control input to a SymNet DSP parameter.)
The Symetrix model RC-3 is the perfect potentiometer match for the Control I/O. Suitable potentiometers, switches and
encoders might also be sourced from electronic parts suppliers such as Digi-key. Note that encoders must be of the mechanical
type.

Open Collector Output Wiring
The following illustrations depict three typical open collector output hook ups. The most common uses for the open collector
outputs are to fire external LED indicators (LED lit when OC inactive) or drive external relays. (Please see the SymNet Designer
online help for information on how to address an Open Collector output in a SymNet DSP design.)
