VistaLINK® General Purpose Interface Module

Product Manual Product Manual
VistaLINK® enabled

The 7700GPI VistaLINK® General Purpose Interface module links third-party equipment and Evertz's VistaLINK® Network Management System (NMS). Third-party equipment with fault alarming capabilities through General Purpose Interface outputs (GPO) can communicate fault alarm conditions to the VistaLINK® application software through this GPO to SNMP translator thereby extending fault monitoring capabilities across the broadcast network.

Equipped with a Linear Time Code (LTC) input, the 7700GPI module can synchronize logged fault alarms within the VistaLINK® application software with the facility clock for accurate alarm acknowledgement and record-keeping. In addition it is possible to label each GPI input for easier notification. The label follows the fault message (trap) through to the VistaLINK® PRO server and onto email/pager notifications (if enabled).

The GPI module is also equipped with three NC/CO GPI outputs (GPO) and can be utilized to relay a "message" from the VistaLINK® system to connected gear. Configuration changes or additional fault alarming are possible through this interface.

VistaLINK® offers remote monitoring, control and configuration capabilities via Simple Network Management Protocol (SNMP) giving the flexibility to manage operations, including signal monitoring and module configuration from SNMP-enabled control systems (Manager or NMS).


  • 20 opto-isolated General Purpose Interface inputs (GPI)
  • Enabled GPI inputs/alerts translated and reported to Network Management System (NMS) user interface via SNMP
  • Selectable +5V or +12V supply for driving GPI over longer cable runs
  • 3 relay closure General Purpose Interface outputs (GPO)
  • GPI/GPO easily accessed through pin-headers (2x6 Phoenix Terminal Blocks) on rear plate
  • 1 LTC input for module synchronization of fault alarms to facility time
  • Modular, conveniently fits into 7800FR 3RU frame
    • Module status LED and 20 GPI LEDs for simple GPI input diagnositics
    • Frame status trigger
    • Jumper-configurable RS-232/RS-422 input serial COM port for serial protocol interface translation
    • VistaLINK® capable for remote monitoring and control via SNMP (using VistaLINK® PRO) when installed in 7800FR frame with a 7700FC VistaLINK® Frame Controller
