External Start/Stop Input (EXT I/O)
You can use an external signal to start and stop the DL850E/DL850EV.
External Start/Stop Input Terminal
The External Start/Stop Input terminal and the GO/NO-GO I/O terminal are the same terminal. This
terminal is used as an external start/stop input when the GO/NO-GO determination I/O function is not
used (when on the GO/NO-GO menu, Mode is set to OFF).
Specifications
The connector uses an RJ-11 modular jack. Connect the separately sold 720911 cable to the
