The BSS BLUGPX is a network-controlled GPIO expander for Soundweb London systems, adding a large bank of control inputs, logic outputs and relays for projects that need extra analogue control and interfacing capability. It features the same rich palette of Logic Objects as other Soundweb London devices, dual PoE Ethernet ports, an RS-232 port and configurable front-panel indication, all in a 1U chassis.

Powering & ControlThe BLUGPX is configured, controlled, monitored and powered via either of its two PoE-enabled Ethernet ports, and can also be controlled and monitored over the RS-232 serial port. A 12VDC connector provides secondary power for backup, with a front-panel Power Supply LED indicating status.
Features
36 control inputs for contact closures, resistor ladders or potentiometers
23 logic outputs for LEDs, relays and voltage-controlled components
8 integrated relay outputs, each with NO and NC terminals
47 Common (ground) and 12 Reference connections for simplified wiring
Two PoE-enabled Ethernet ports for communications and primary power
12VDC connector for secondary / backup power
RS-232 port for serial control and monitoring
48 software-programmable multi-colour (red / green / yellow) LEDs
Programmable 80×16 monochrome LCD and 4 kHz piezo buzzer
Open architecture, configured in HiQnet London Architect
NoteThe BLUGPX is a GPIO expander – it adds control and logic interfacing to a Soundweb London system but does not process audio itself.
