Cabling
8900 module slots are interchangeable within the frame. The maximum
number of modules the frame will accept is ten.
Figure 4 illustrates the rear
connector plate for an 8900 Series frame.

Loopthrough Input
Connect an input source (NTSC reference color black) to one of the
loopthrough input connectors, J9 or J10 (See
Figure 5 ). Terminate the
unused connector into 75 Ω .
Outputs
There are four duplicate outputs for the 8980TLS module—J1 through J4.
The destination equipment should have an input impedance of 75
Ω unless
it has loopthrough inputs, in which case the loopthrough inputs must be
terminated into 75
Ω .
