Drive levels
Refer to Figure 56 for pin locations. Note the notch and red mark on the bias connector
outer ring are used for reference.
To turn ON a port, supply a –7VDC (± 0.35V) bias voltage.
Current is approximately 41 mA.
To turn OFF a port, supply a +6.3VDC (± 0.32V) bias voltage.
Current is approximately 95 mA.
Only one port can be turned on at a time, or all ports can be off.
The total current is approximately 400 mA for 85332B, 200 mA for 85331B with all
ports off.
