Grass Valley 8900NET v.4.4.0 - Manual (Page 38)

38 8900NET (Net Card) — Instruction Manual
Using the 8900NET GUI
8500/8800 Module Support
Installation of 8500 and 8800 modules shipped prior to November 15, 1999
will cause interruption of the Gecko and GeckoFlex frame communication
bus. Modules shipped after this date have pins removed in the rear con-
nector to provide compatibility. Compatible modules can be identified by
the absence of connector pins 10 and 50 (see
Figure 16 ). Incompatible
legacy modules can be returned to Grass Valley for upgrade to the new con-
nector.
Note If an unmodified legacy module is installed in the frame, the frame commu-
nication bus will be interrupted and all module icons in the frame status
display will be red. This problem occurs with legacy modules only and does
not occur with other 8900 Series modules.
