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
communication will be ready. (Step 7)
If the ERR indicators do not go out even though five
seconds or more have elapsed after the power is
turned ON, the connections have not been
recognized correctly, so observe the following points
and then turn ON the power to the Amplifier Unit
again.
• Is the switch on the Amplifier Unit set to "RUN"?
(Step 3)
• Are connections between the Amplifier Units as
well as between Amplifier Units and 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.
7.
Start the Smart Monitor.
Communications will start automatically.
If communications do not start, turn OFF the power to the Interface Unit and Amplifier Units, and repeat steps
from step 6.
If communications still do not start, check the following points (i) to (iii), 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 will be set automatically).
• Exit 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 sent to the Interface Unit).
• Is the Smart Monitor connected with the correct cable? (Check whether 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
transmitted, 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 RUN mode? (Step 3)
