Cabling
Refer to Figure 3 when cabling your 8936 module. This illustration shows the
typical input and outputs for an 8900 Series module.
Loop-through Input
Connect an input source to one of the loopthrough input connectors, J9 or
J10.
Note It is recommended that no more than five digital modules be looped, using
cables less than two meters in length, and with an input cable less than 200
meters of Belden 8281 (or equivalent).
This loopthrough input must be terminated. The recommended termina-
tion for serial digital signals is CANARE BCP-TA (or equivalent).
Performance of looping inputs to equipment other than 8900 modules has
not been verified; therefore, care should be taken if this is required.
Outputs
There are eight outputs for the 8936 module, J1 through J8. The destination
equipment should have an input impedance of 75
Ω unless it has
loopthrough inputs, in which case the loopthrough inputs must be termi-
nated into 75
Ω .
