# Parallel Remote Control

In addition to IP-based remote control, PDM II simultaneously supports traditional control systems for maximum flexibility, including GPIO or "Contact Closure."

PDM II supports five inputs and five outputs for remote control through its rear panel female DB-15 connector. Multiple inputs or outputs can be assigned to the same function when isolated circuits are required. Inputs and outputs are optoisolated, with low status being active.

Please see the [GPIO section](/v1/docs/gpio-menu) for detailed information.
