SDM-2020 Satellite Demodulator Revision 4
ASI/RS-422Data Interface MN/SDM2020D.IOM
9–6
Single-ended signals (MF and DF fault signals) are open collector where:
V
oh
=12V max. and V
ol
=0.5V max. @ I
ol
=8 ma.
A pull-up resistor, external to the equipment, is required.
The fault signals, MF and DF, operate as follows: A fault is indicated by an “OFF” (high)
and OK status is indicated by an “ON” (low).

9.1.3.3 Receive Output Connectors, J6/J7, BNC, Female
Duplicate signals exit both of these connectors on the demodulator to deliver receive data
to the terrestrial interface. J6 and J7 are both active at all times, and no selection is
required.
