MODEL 204

ANNOUNCER’S CONSOLE

Application Firmware Version

Display

There are two ways in which the version

number of the Model 204’s application

ﬁrmware (embedded software) can be

identiﬁed. One requires only the Model

204 unit and involves a button-press

sequence performed upon power up. The

other method utilizes the Model 204 and

the STcontroller software application.

Either method may prove to be useful

when working with factory personnel on

application support and troubleshooting.

As part of the Model 204’s power-up se-

quence the unit’s application ﬁrmware can

be directly displayed. Before connecting

the PoE-enabled Ethernet cable, press

and hold the talkback button. Then con-

nect the Ethernet cable. Upon application

of PoE power the Model 204 will not go

through its normal power-up sequence

but instead will display the ﬁrmware ver-

sion. The green LED associated with the

main button will “ﬂash” to display the major

version number. Then the red LED associ-

ated with the talkback button will “ﬂash”

to display the minor version number. The

LEDs will then remain off until the talkback

button is released. Once the talkback but-

ton is released normal operation will then

take place. As an example of what would

be a typical ﬁrmware display, if the main

button’s LED “ﬂashes” green once followed

by the talkback button’s LED “ﬂashing”

red twice it would indicate that applica-

tion ﬁrmware version 1.2 is present in the

Model 204.

A selection in the STcontroller software

application allows the Model 204’s ap-

plication ﬁrmware version to be identiﬁed.

Connect the Model 204 unit to the network

and let it connect and start to function.

Then, after starting STcontroller, review

the list of identiﬁed devices and select the

speciﬁc Model 204 from which you want to

determine its application ﬁrmware version.

Then select Version under the Device tab.

A page will then display that will provide

lots of useful information. This includes the

application ﬁrmware version and well as

details on the Dante interface ﬁrmware.

Application Firmware Update

Procedure

It’s possible that updated versions of the

application ﬁrmware (embedded software)

that is utilized by the Model 204’s processor

(microcontroller or MCU) integrated circuit

will be released to add features or correct

issues. Refer to the Studio Technologies

website for the latest application ﬁrmware

ﬁle. The unit has the ability to load a revised

ﬁle into the MCU’s non-volatile memory by

way of a USB interface. The Model 204

implements a USB host function that direct-

ly supports connection of a USB ﬂash drive.

The Model 204’s MCU updates its ﬁrmware

using a ﬁle named m204.bin.

The update process begins by preparing

a USB ﬂash drive. The ﬂash drive doesn’t

have to be empty (blank) but must be in the

personal-computer-standard FAT32 format.

Save the new ﬁrmware ﬁle in the root direc-

tory with a name of m204.bin. Studio Tech-

nologies will supply the application ﬁrmware

ﬁle inside a .zip archive ﬁle. While the

ﬁrmware ﬁle inside of the zip ﬁle will adhere

to the naming convention required by the

Model 204, the name of the zip ﬁle itself will

include the ﬁle’s version number. For exam-

ple, a ﬁle named m204v1r1MCU.zip would

indicate that version 1.1 of the application

ﬁrmware (m204.bin) is contained within this

zip ﬁle.
