Setting Pulse Input Type (PULSE.IN)
Seven input types may be set for the pulse input, and it may be disabled. See Pulse Input specifications
on page 11.
The pulse input is disabled with factory settings.
Press Enter to access the menu then press the Up to scroll through the flashing choices. Press Enter to
accept the setting. Press Menu to back out of a menu, or hold Menu to exit at any time.
The following input types may be selected.
