8 8921ADT Instruction Manual
Installation
Installation
Installation of the 8921ADT module is a process of:
1. Setting on-board jumpers for desired output formats,
2. Placing the module in the proper audio frame slot, and
3. Cabling and terminating signal ports.
The 8921ADT module can be plugged in and removed from a Gecko 8900
audio frame with power on. When power is applied to the module, LED
indicators reflect the initialization process (see
Power Up on page 14 ).
Module On-board Jumper Settings
A number of jumpers must be set on the module to determine module for-
matting before installing it in the frame. Refer to
Table 1 for a summary of
each jumper and Figure 1 on page 9 for jumper locations on the module
circuit board.
