Installation
Installation
Installation of the 8900 Analog Video DA modules is a process of:
1. Setting on-board module jumper settings for desired operation
(
page 9 ),
2. Placing the module in the proper video frame slot ( page 12 ), and
3. Cabling and terminating signal ports ( page 15 ).
The DA module can be plugged in and removed from the frame with
power on. When power is applied to the module, LED indicators reflect the
initialization process (see
Power Up on page 16 ).
On-board Jumper Settings
Each 8900 Analog Video DA module requires jumper settings to determine
the desired operating modes as outlined in
Table 2 and shown in Figure 1 .
Figure 1 on page 10 illustrates each of the on-board jumpers on the circuit
board. Note that depending on the model, some components may not be
present. For details on setting each jumper, refer to the specific jumper
headings given in this section.
