BPower/Reset LED — The green LED indicator duplicates the front panel LED operation (see the “Reset Actuator and LED” section for additional information).

CLine 1-4 input connectors — 6-pole 3.5 mm double-stacked captive screw connectors accept balanced or unbalanced mono line level signals. Line inputs provide gain settings to accommodate consumer (-10 dBV) and professional (+4 dBu) operating line level sources. Up to four mono line inputs, balanced and unbalanced in any combination may be connected to these inputs (see the following diagram for wiring instructions).

FDigital input connector — A 6-pole 3.5 mm captive screw connector (shared with the RS-232 port) provides three configurable input ports allowing connection to various devices including motion detectors, alarms, buttons, photo (light) sensors, and temperature sensors. This connector shares a common ground with the RS-232 connector (E).
