ports or via a built in Ethernet port. These ports can provide bi-directional protocol support. The
7700PTX is equipped with 20 general purpose inputs that can be used for the purposes of alarming or
tally.
Function:
The function of the 7700PTX generally falls into one of four categories:
1. Third-Party Router Control: In this mode the 7700PTX affords VistaLINK
and monitor third-party routers.
monitoring equipment.
2. Third-Party UMD Interface: In this mode the 7700PTX translates third-party UMD protocol data
into a format suitable for Evertz monitoring equipment.
3. Third-Party Switcher Interface: In this mode the 7700PTX extracts tally information from third-
party switchers and translates and conveys that tally information to Evertz monitoring
equipment.
4. Third-Party Device Control: In this mode the 7700PTX allows VistaLINK
devices such as satellite controllers.
