STcontroller
Testing & Troubleshooting
Studio Technologies has created a video which provides details on how to fix an empty device list in STcontroller. Typically, a simple selection within Dante controller is all that is needed to restore full functionality.
If the device list within STcontroller is blank, the correct Dante interface is probably not selected. One might also notice that their network interfaces listed in the drop down menu cannot be selected.
This results in STcontroller failing to identify supported Studio Technologies Dante products on the network thus leaving the device list empty.

Firmware Updates
STcontroller
Studio Technologies has created a video which provides details on how to update the main and Dante firmware on compatible Studio Technologies devices. Typically only a USB drive and a computer are required to update the units.
Updating firmware typically only requires a USB drive and a computer to fully update all Dante compatible units. Some units require the front cover to be removed first before a USB drive can be inserted,

Model 5401A
Model 5402
ST 2110
The Model 5401A Dante Leader Clock and the Model 5402 Dante Leader Clock with GNSS Synchronization were primarily designed for use in applications that utilize devices running “native” Dante. To support the timing needs of these devices Precision Time Protocol Version 1 (IEEE-1588-2002 or “PTP v1”) was implemented. The units’ PTP v1 implementation functions very well, including in redundant Dante applications. (Independent Ethernet networks connected to the Primary and Secondary Ethernet ports on the back panel of the Model 5401A and Model 5402 units.) Even in large installations with literally hundreds of Dante devices,

Recommendations
Over the years people have asked us if there were specific makes or models of networking equipment that we could recommend. Their goal was to optimize their network deployment to function well with our Dante®-enabled products. Our standard reply has always been that any Ethernet networking equipment that complies with the relevant IEEE® standards should work acceptably. We were hesitant to recommend any specific equipment as there were many fine brands of equipment that could meet the requirements.

Studio Technologies has created a video which provides details on how to repair the pushbutton switches that are used in the StudioComm desktop control consoles and Model 400-Series fiber transport units. Typically only a cleaning is required to return them to full working order.
Cleaning typically only requires a small flathead screwdriver or a thin plastic pry tool, a pencil eraser, a cotton swab, and a can of contact cleaner.

AES67
Dante
ST 2110
Dante® audio-over-Ethernet networking technology can support the requirements of the AES67 and SMPTE® ST 2110 technical standards. Studio Technologies offers a number of Dante-enabled products, all of which are capable of having their AES67 and/or ST 2110 capability enabled. This is performed using the Dante Controller software application.
For compatibility with a number important AES67 and ST 2110 technical parameters, Dante was required to implement several DSCP (Differentiated Services Code Point or DiffServ) tag values.

The ping command can be very useful, helping to determine if a network-connected device is available and functioning correctly. (Ping is a utility that was developed in the 1980s and utilizes the ICMP Echo Request and ICMP Echo Reply network resources.) The management ports on a number of Studio Technologies’ products support the ping command. These include the Models 792, 5401, 5401A, 5402, 5412, 5418, 5422, 5422A, 5482, 5512, and 5518. It’s important to note that one user issue can arise when “pinging”

Intercom Audio Engine
Model 5422A
Performance
A Model 5422A Dante Intercom Audio Engine has a maximum group size of 32 channels. (In this case, the one group would be using all 32 channels of an audio engine.) So, in theory, a 32-channel group configured for the Party-Line operating mode would allow a maximum of 32 users to be part of that party-line (PL) circuit or channel. In the vast majority of applications that should be sufficient; having anything close to 32 users on the same PL would be an exception.

Model 76
Testing & Troubleshooting
The Model 76 Central Controller was manufactured for a number of years but was discontinued in August of 2012 due to parts availability and decrease in demand. It was an excellent product that is still in use by many facilities. We have become aware that after ten or more years of field operation an oscillation in the range of 17-18 kHz can appear in the unit’s analog output channels. It was found that the unit’s –15 volt DC power supply “rail”
