Communications

The refresh button works just like the refresh button on your internet browser. It will reload the information in the recent activity list.

Clear Completed

The clear completed button will remove anything in the recent activity list which is listed as being completed.

Clear Errors

Clear errors will remove anything in the recent activity list which has failed or listed as in error for some reason.

For a list of communications errors and what causes them, see List of Communications Errors.

Cancel Communications

The "Cancel Communications" function is available in the Account Toolbar. This function may be used to cancel a current (or pending) communication job, but this function should not be considered a "Hangup immediately" command.

When pressed, the communication manager will stop sending upload or download commands to the panel when it is determined to be “SAFE TO STOP". This means that the communication session that you are trying to cancel will NOT hangup with the panel immediately, but will wait until the communication can be ended gracefully, leaving the panel in an operational state.

Global Upload

If a global upload was canceled, data that was uploaded from the panel will be saved, and any options that were not yet uploaded will remain tagged for upload. This allows an opportunity to restart the communication at a later time.

Global Download

If a global download was cancelled, any options that were not downloaded will be saved to the database and tagged for download. The remaining options may be downloaded at a later time.

Tagged Communication

If a tagged communication was cancelled, tags for options that were completed successfully will be cleared, tags for options that were not completed will be saved, and may be restarted at a later time. Data that was uploaded successfully will be saved to the database.

Connection Methods

You may connect to a DSC panel using the DLS IV software in a variety of different ways. These include PC-Link, T-Link, and PSTN.

PC-Link

PC-Link is a method of connecting to a DSC panel by connecting a serial port on your computer directly to the security panel.

TL Network

The TL network connection method refers to connecting to the security panel via a T-Link module which allows connection via a local or wide area network.

For more information on connecting to a panel via T-Link, see TL Network.

PSTN

PSTN stands for Public Switched Telephone Network. This method is the most common. In order to connect to a DSC panel over the telephone line, you will need an MD-12 modem connected to a free serial port on your computer, a free phone line for the modem, and the telephone number that the security panel is connected to on site.

Modem Manager Configuration

The modem manager configuration can be found under the tools menu in the toolbar. The modem manager can be used to configure the various connection methods and options associated with them.

For more information, see Modem Manager Configuration.

Communication Operations

Global Upload

If you select to do a global upload, the DLS IV software will connect to the panel via whichever means you have selected and all of the data in the panel will be transferred to the computer. The global upload gets all data from the panel excluding the event buffer.

Global Download

A global download will take all of the data and information you have programmed in the account file on your computer and transfer that to the security panel.

Communicate Tags

If you select the communicate tags button, any options you have tagged, either upload or download, will communicate. The DLS IV software will connect to the panel and begin both uploading and downloading any options you have selected.

Upload Event Buffer

Uploading the panels event buffer will take all events from the panels event buffer and transfer them to the DLS IV software. The size of the event buffer and events therein may vary from panel to panel.

Clear All Tags

The clear all tags button will remove any upload or download tags you have selected on any options within the DLS IV account file.
