TITLEB OX
 GPI Manager – this feature in TitleBox
allows controlling objects through receiving
certain signals on the PC COM ports. In the GPI
manager, you can view all GPI events and the
objects to which they have been assigned. To
specify the “meaning” of each signal at each
COM port, right-click in an object and select
Assign GPI Event.
 Active Event (Tally) - This function
keeps you informed whether there is any graphics
showing on the screen or not. If there is at least one object that is being played, a high
pulse is sent to the specified COM port. When there are no objects played, the pulse goes
low. Thus, any external GPI device could be activated when there are no objects played
out in TitleBox (i.e. a sound alarm to let the operator know that there is no graphics
displayed). After choosing this menu item, you can select the desired COM port or [None]
if you do not want to send out any pulses. Besides, you can specify the signal type (RTS or
DTR). RTS will send a pulse to pin 7, and DTR – to pin 4. Pin 5 is the ground. For mo re
details, please refer to the GPI pin out description in Appendix 1.
