Communicating with the Static Electricity Smart Monitor via the Interface Unit
6.
Turn ON the power supply to the Amplifier Unit.
When the Amplifier Unit is powered ON, the
Interface Unit will also be powered ON.
When the ERR indicators for the Interface Unit's
sensor communication
terminal communication indicator go out, this
indicates that communication is ready. → (Step 7)
If the ERR indicators do not go out even though five
seconds or more have elapsed since the power was
turned ON, the connections have not been
recognized correctly. Check the following points and
then turn ON the Amplifier Unit again.
• Is the mode switch on the Amplifier Unit set to
[RUN]? → (Step 3)
• Are connections between the Amplifier Units as
well as between Amplifier Units and the Interface
Unit correct? → (Steps 4, 5)
• Have the Amplifier Units started up correctly?
(If they have not started up correctly due to
connection failure between Amplifier Units and
Sensor Head, eliminate the cause of the error.)
7.
Start up the Smart Monitor.
Communication starts automatically.
If communication does not start, turn OFF the Interface Unit and Amplifier Units, and repeat the procedure
from step 6.
If communication still does not start, check the following points (i) to (iv), and then restart the Smart Monitor.
(i) A communication port No. different from that on the personal computer is used or the communication port
is used by another application program.
• Set the same communication port No. as that on the personal computer (the other communication
conditions are set automatically).
• Quit the application program that is using the communication port.
(ii) The BUSY external terminal communication indicator does not light up when Smart Monitor is started (no
signal is being sent to the Interface Unit).
• Is the Smart Monitor connected with the correct cable? (Check if it is connected with a straight cable by
mistake.)→ (step 4)
• Are the connections normal? → (steps 4, 5)
• Is the correct communication port set?
(iii) The BUSY external terminal communication indicator lights up for a moment when a command is sent,
but there is no response from the Interface Unit.
• Is the switch on the bottom of the Interface Unit set to the default side? → (step 2)
• Is the Amplifier Unit set to the RUN mode? → (step 3)
(iv) An error message appears on the Smart Monitor screen and Smart Monitor cannot start up.
• Is the Interface Unit in use the correct one?
(The dedicated Interface Unit (ZJ-SF11) is required to communicate with ZJ-SDA.)
