Section 2 — Startup & Configuration
Configuring GPI Outputs
GPI Output triggers each time there is a cut on the PGM Bus. This
GPI is typically connected to an external device such as a clock/
timer which is reset by each trigger. Such a clock would then
indicate how long the current source has been on air.
The duration of GPI Output Triggers can now be configured by
the number of fields. This configuration is set using the GPI
Outputs Menu.
Use the GPI Outputs Menu to set E-MEM levels for each assigned
GPI. You may also set the duration of the GPI trigger signal. This
menu is accessed from the Config/External If Menu.
1. Use the SELECT GPI button to select the desired GPI number.
2. Press the E-MEM LEVEL button to select the desired E-MEM
level.
3. Use the LENGTH soft knob to select the required GPI trigger
duration in fields.
4. Repeat Steps 1 through 3 for other GPIs.
