SW2 SWITCH 3: CONTROL SYSTEM COMPATIBILITY
Coaxial Control Systems
Although Spectra IV/Spectra IV SE dome systems can operate with coaxial control systems from many manufacturers, the system is designed for optimal performance with Pelco Coaxitron® control products within the length specified for coaxial cable.
To compensate for coaxial control systems from other manufacturers, Pelco has provided DIP switch

Notes:
•This coaxial control system compatibility feature is only available for dome drive revisions A4 and later (revisions A0 and later for Spectra IV Horizon dome drives). The revision number can be found on the barcode label on the top of the dome drive. Software version 1.090 and later indicates this mode is available by placing an asterisk next to the switch number in the Dip Switch Information menu.
•In some configurations, Pelco CM9502 Series matrix systems use nonstandard Coaxitron commands for functions like pattern playback. If you experience problems with these functions, set

SW2 SWITCHES 4–5: SERIAL PORT SETTINGS
RS-422 Setting (Default)
For control, only two wires should be connected to the RX- and RX+ connectors on the circuit board inside the back box. For bidirectional control, four wires should be connected to the
RS-485, 4-Wire Setting
Note: This setting is most commonly used with Pelco Endura® systems.
RS-485, 2-Wire Setting
This setting is used to allow the Spectra dome system to transmit and receive commands on the same pair of wires. Only two wires should be connected to the RX- and RX+ connectors on the circuit board inside the back box.
