5.5 GO/NO-GO Determination I/O and External
Start/Stop Input (EXT I/O)
Connecting to Other Instruments
CAUTION
• Do not apply external voltage to the NO-GO OUT and GO OUT output pins. Doing so may
damage the instrument.
• When connecting the GO/NO-GO determination signal output to another device, do not
connect the wrong signal pin. Doing so may damage the DL850/DL850V or the connected
instrument.
• Do not connect a USB cable to the GO/NO-GO output terminal. Doing so may damage the
instrument.
About the External I/O Cable (720911; sold separately)
• Do not use the cable for anything other than the DL850/DL850V external I/O.
• Refer to the following figure to connect the cable to an external device.

GO/NO-GO Determination I/O
You can apply an external signal to the DL850/DL850V’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.
