Portaprompt's  WinDigi prompting software has been specifically written and designed to interface with ENPS's Media Server Communications Protocol (MOS). This tight integration with WinDigi via the MOS protocol enables ENPS to control all the features of the WinDigi prompter automatically so improving the efficiency of the prompting function in a busy newsroom environment. Via MOS WinDigi can request any rundown or multiple run-orders to be prompted, accept rundown and script changes automatically during rehearsal and live transmission. Using the MOS interface with WinDigi also allows for an even closer interface with ENPS for presenter preferences such as True type font choice, size and style, colour, bold, italics, underline and reverse background/foreground.

Using the MOS Active X implementation WinDigi can remotely access any run-order, or start at any story in the run-order. The prompter output can be controlled by a hand control or a Presenter foot control.

WinDigi is fully Windows 2000, NT & XP compatible and via the MOS gateway able to interface ENPS in most languages. WinDigi also has a Time to air clock with programmable alarm warnings, adjustable eye-line,
margins and idents. Portaprompt is a member of the ENPS MOS Partner group and actively supports the ENPS MOS user group meetings.
