ScanControl

One Program, Multiple Scanners, Made in USA

• Initial Screen Location - Sets the default value for initial screen location for all screens. This

option allows users with lower resolution monitors (800 X 600) to maximize the screen area to

be used by ScanControl. 800 / 600 screen users may want to set this value to “Top Left” so they

see full screens when the program runs. Higher resolution screen users would want this setting

to be “Centered” in most cases.

• Print Columns - User can select the number of columns that will appear on a bank data printout.

Choices can be made for Channel printouts and Talkgroup ID printouts.

• Intelligent Audio Capture (IAC) Options:

o Audio Device – Drop down list containing available audio devices in the PC. Select the

device that will be connected to the scanner for audio input. This is typically the PC’s

sound card.

o Audio Device Line – Drop down list containing the available device line(s) for the audio

device selected above. A device line is a specific input to which the scanner’s audio

output should be connected. Choices here might be line in, mic in, mixer, etc.

o Format – Drop down list containing available sound file formats (i.e compression types)

for storing the recorded audio. Only MP3 is supported in the initial release of

ScanControl Version 6.x.

o Wave Format – Drop down list containing available Bit Rate, Sampling Rate and

Channel combinations. The higher the Bit and Sampling Rates the better the sound

quality. However, the higher the Bit and Sampling Rates the larger the file size of the

recorded audio file. Choose Mono or Stereo channels depending on whether or not your

radio outputs audio in Mono or Stereo.

o Group by – Drop down list containing IAC Group by options. Select an audio file

"Grouping" option. The three current options are Session, Date/Time and Chnl / TGID.

The Session option places all the audio files for all Chnls / TGIDs / Searches etc. into one

folder labeled with a date / time stamp based on when the session started. The Date /

Time option creates a folder hierarchy with the top folder being the Date, subfolders

under it, one for each hour of the day and then each of the Chnl / TGID / Search etc.

audio streams is placed into a folder based on the hour in which the audio stream began.

The Chnl / TGID option creates a folder for each Chnl / TGID being monitored and

places each audio stream file into the appropriate folder.

o THold – Drop down list for selecting the silence threshold level. This threshold level

tells ScanControl what audio input level value should be the threshold for what the

software should consider as “silence”, or no audio. This value is used to determine when

the audio recorder should turn on or off based on the amplitude of the incoming audio.

This functions much like a VOX control on a voice activated tape recorder. The default

level of 100 is optimized for almost all situations and should rarely have to be changed.
