GO/NO-GO Determination I/O
You can apply an external signal to the DL850E/DL850EV's GO/NO-GO I/O terminal and perform GO/
NO-GO determination, and you can output the results of GO/NO-GO determination from the GO/NO-
GO I/O terminal.
GO/NO-GO I/O Connector
Type
The connector uses an RJ-11 modular jack. Use the external I/O cable accessory (720911; sold
separately). If you are using a commercially sold cable (four-conductor modular telephone cable),
wire the pins according to the above figure.
I/O Level
Within 0 to 5 V, threshold level: TTL

Input Signal
START IN (Negative logic)
Use this signal to perform GO/NO-GO determination by synchronizing to an external input signal.
The signal is only valid when on the GO/NO-GO menu, Remote is set to ON. If Remote is set to
OFF, GO/NO-GO determination is performed regardless of the external signal input (the GO/ NO-
GO determination result is output).
