Power connector
2-pin terminal block for DC power input. Use a Safety Extra Low Voltage (SELV) compliant limited power source (LPS) with either
a rated output power limited to ≤100 W or a rated output current limited to ≤5 A.
RS485/RS422 connector
Two 2-pin terminal blocks for RS485/RS422 serial interface used to control auxiliary equipment such as pan-tilt devices.
The serial port can be configured to support:
• Two-wire RS485 half duplex
• Four-wire RS485 full duplex

Digital input – Connect to pin 1 to activate, or leave floating
(unconnected) to deactivate.
Pin 3 and 4 can be supervised. To use supervised input, install
end-of-line resistors. See connection diagram for information about
how to connect the resistors.
Digital output – Internally connected to pin 1 (DC ground) when
active, and floating (unconnected) when inactive. If used with an
inductive load, e.g., a relay, connect a diode in parallel with the load,
to protect against voltage transients.
