6.6 Electrical Characteristics

6.3.1 DC Isolated Outputs

Each DC output (pins 1 through 11, pins 19 through 21, pins 30 through 31) is isolated
using an open collector output opto-coupler. The output voltage of each line is set by a
pull-up resistor on the handler interface board. The pull-up resistors can be connected to
