26 Pelco Manual C543M-A (7/03)
CM9760-DFL (Rear Panel Downframe Looping Card)
What Does It Look Like?
The DFL card is essentially an RPC card with an attached downframing cable. The
card itself looks like the one pictured in Figure 16.
What Are Its Functions?
The DFL card is used in the last bay in a downframe configuration and provides the
capability to loop out video. The card contains termination jumpers that must be set
in the unterminated position when looping to another device is required. When
looping is not required, the termination jumpers must be set in the terminated position.
The DFL card can be used in the CM9760-MXB to increase the number of available
monitors whether or not looping is required. In addition, the DFL card is the only
card that can be used in the CM9760-MXBL, which is an unpowered, downframed
matrix bay that contains 16 DFL card slots for supporting 256 video loop-out con-
nections. (When looping is required in a 9760 system that has 16 or fewer monitors
and more than 128 cameras, the CM9760-MXBL containing DFLs must be used.)
For additional information about the DFL card, refer to Section 5.1.
Where Is It Installed?
Physically (as long as function parameters are met), a DFL card can be installed in
any slot position.
