Paragraph 2.3.16 contains the instructions for changing the Handler mode. Paragraphs 2.3.3 and
2.3.4 contain instructions for setting the Trigger Delay time and selecting the Trigger Edge.
Figure 3-6 illustrates the Trigger function.

Output Signals
The output lines of the 1730T Handler interface are open collector drivers that pull each signal
line to a low voltage, signal ground when the signal is active (true). Each external line should be
pulled up (with a resistor) to a positive voltage between 5V and 24V. The pull-up resistor must
limit the current to < 6mA for a signal of a comparison function and to < 5mA for a control
signal (EOT).
