11.10 Using the GO/NO-GO Determination I/O
Function
GO/NO-GO determination can be performed by applying an external signal to the GO/
NO-GO I/O terminal of the DL750/DL750P. The determination result can also be output
externally from the terminal.
GO/NO-GO Determination I/O Terminal Connector
Type
Modular jack (RJ-11). Use the optional accessory 366973 (sold separately) for the
cable. If you are using a commercially sold cable (4 contact modular cable for telephone
circuits), wire the pins according to the following figure.

Input Signal
START IN (Negative Logic)
This signal is used when performing GO/NO-GO determination by synchronizing to an
external input signal. The signal is valid only when “Remote” is ON. If “Remote” is OFF,
GO/NO-GO determination is performed regardless of the external signal input (the GO/
NO-GO determination result is output).
See below for the timing chart.
