Frame Health Alarm

The Frame Health Alarm is accessed through pins 8 and 9 of the RS-232
connector. Details for connecting an external customer-supplied alarm are
given in the Gecko 8900 Series Frames Instruction Manual. The Frame
Alarm responds to conditions enabled on the 8900NET Network Interface
module with DIP switches S1 and S2 as given in

Table 2 on page 19

.

Note

Earlier version 8900 frames used a BNC connector labeled SMPTE ALARM to
access the alarm connection. For information concerning the SMPTE Alarm
bus cable, refer to the

Gecko 8900 Frames Instruction Manual.

RS-232 Communication Port Cable

The nine-pin RS-232 connector is used to connect the frame to a PC to ini-
tially set the frame’s network communication parameters. After network
communication is established, subsequent changes to these parameters can
be made using the network GUI.

CAUTION

The RS-232 cable should be removed after completing the initial frame setup.
Leaving a long serial cable connected to the frame without a connection at
the other end may freeze the 8900NET module startup routine.
