The Soundweb London BLU-GPX is a network-controlled GPIO expander which facilitates the cost-effective addition of Control Inputs, Logic Outputs, and Relays to systems requiring extra analog control/interfacing capability. The BLU-GPX features the same rich palette of Logic Objects found in other Soundweb London devices, two PoE-enabled Ethernet ports for communications and primary power, a 12VDC power connector for secondary power, an RS-232 port for compatibility with serial devices, a bank of user-configurable front panel LEDs, a user-configurable front panel LCD, a user-configurable piezo buzzer for audible indication, and locate functionality.

The BLU-GPX has General Purpose LED indicators on the front panel. Each of these LED indicators can be assigned to a control port or can be driven by the Soundweb London Logic system.
A logic source or a logic end can be assigned to any front panel LED. Simply drag the Logic Object to the desired front panel LED. The front panel LED will then reflect the state of the logic object.
When an LED association is made to a control port, the front panel LED state will be driven from the control port state and not from the LED control state (as would be the case where no control port association existed).
Assign the LED to an assigned control port via the Configure Control Ports window, using the drop-down menu under LED ASSIGNMENT:

BSS Audio incorporates high quality mechanical fans in some products. All mechanical fans have a limited life expectancy. We recommend annual inspection of fans for dust occlusion and excessive noise. Fan assemblies should be replaced after six to ten years of use. Environmental factors such as elevated temperature, dust, and smoke can adversely affect fan life. Systems exposed to these conditions should be inspected more frequently. Fan replacement can be performed either at the factory or by an experienced technician in the field. Please contact BSS Technical Support for more information on purchasing replacement parts or product service. BSS Audio has a policy of continued product improvement and accordingly reserves the right to change features and specifications without prior notice.
