Studio Technologies Model 392 Visual Indicator Module

Studio Technologies Model 392 Visual Indicator Module

The Model 392 is a compact, lightweight unit that is primarily intended for fixed applications with mounting in a US-standard 2-gang electrical box. The unit's optical lens conforms to the requirements of a single-opening Decora^®-style size, allowing a 2-gang trim plate with centered single Decora opening to be used to complete the "look" of an installation. Standard trim plates are available in a variety of materials and finishes.

Configuration of the Model 392 is performed using the STcontroller software application. Choices include the display activation method, the active and inactive LED colors, the active and inactive LED intensity, and the active action.

Applications

The on and off status of the Model 392's display can be controlled using a "virtual" selection within STcontroller. This is a simple means of controlling the unit, but would require user intervention. While available, in most cases this method will be used only during deployment and testing.

The Model 392 is also directly compatible with the call signals generated by the popular Studio Technologies' Dante-enabled beltpacks and intercom stations. These Dante-connected user devices generate 20 kHz tones whenever their call button is activated. Model 392 applications can also employ the Studio Technologies' intercom interface units to provide compatibility with legacy analog PL intercom systems. Interface units are available that at compatible with Clear-Com^® PL as well as the TW-series from RTS^®/Bosch^®.

In addition to responding to intercom beltpack call requests, the Model 392 can also be used in other Dante-related applications. These include allowing one of the contact-closure inputs on a Studio Technologies' Model 44D Audio Interface to trigger the display on a Model 392. Being Dante networked audio devices, the Model 392 and Model 44D units will function together as long as they are located on the same network, whether the devices are in the same room or on the opposite sides of a university campus. Another application would be to use signals generated by other products, such as the Studio Technologies' Model 214 and Model 215 Announcer's Consoles, to allow the Model 392 to directly serve as a broadcast "on-air" indicator.

Features

The Model 392 incorporates a trapezoidal-prism-shaped polycarbonate lens lit with multiple red/green/blue (RGB) LEDs. The unit is designed for mounting in a 2-gang electrical box with a lens that is compatible with a single Decora opening. Only a single 100BASE-TX with PoE network connection is required. These characteristics makes the unit ideal for deployment in "new build" applications as well as for retrofitting into existing structures. The Model 392's display lens provides a highly visible, wide viewing field. Configuration choices allow selection of the exact color, intensity, and lighting cadence.

Dante Audio-over-Ethernet

Audio and related data is sent to the Model 392 using the Dante audio-over-Ethernet media networking technology. As a Dante-compliant device, the Model 392's Dante receiver (input) audio channel can be assigned (routed) from a source device using the Dante Controller software application. The Model 392 is compatible with Dante digital audio sources that have a sampling rate of 48 kHz and a bit depth of up to 24.

Ethernet Data and PoE

The Model 392 connects to an Ethernet data network using a standard 100 Mb/s twisted-pair Ethernet interface. The physical interconnection is made by way of an RJ45 jack. Two LEDs display the status of the Ethernet connection. The Model 392's operating power is provided by way of the Ethernet interface using the 802.3af Power-over-Ethernet (PoE) standard. This allows fast and efficient interconnection with an associated data network. To support PoE power management, the Model 392's PoE interface reports to the power sourcing equipment (PSE) that it's a class 1 (very low power) device.

Setup, Configuration, and Operation

Setup, configuration, and operation of the Model 392 is simple. An RJ45 jack is used to interconnect the network interface with a standard twisted-pair Ethernet cable associated with a port on a PoE-enabled network switch. This connection provides both network data and power. The Model 392's compact enclosure can be mounted into a standard 2-gang electric box. A stainless steel trim plate with one Decora-style opening is provided with each unit.

All Model 392 features are configured using the STcontroller personal computer software application. An extensive set of parameters allows the unit's operation to be tailored to meet the needs of many applications.
