Gecko Frames — Instruction Manual 41
Rear Connectors
Frame Alarm Connector
Use of the Frame Alarm requires the presence of either the Frame Monitor
or 8900NET Network Interface module in the frame. Frame Monitor
module features are discussed in
Section 4-Monitoring and Control in this
manual. For information on the 8900NET module see the 8900 Network
Interface Module Instruction Manual.
The Frame Alarm is accessed through pins 8 and 9 of the RS-232 DB-9 con-
nector (Video Frame – J102, Audio Frame – J7) as shown in
Figure 14 . Refer
to Frame Alarm Example on page 43 for using the port in an alarm circuit.
Note Earlier model 8900 frames had a SMPTE ALARM BNC for accessing the
Frame Alarm output. Refer to
SMPTE Alarm Connector on page 58 for cabling
information on older frames.
