3. Problems communicating with the Device
After the proper RC68+ IR trigger is sent to the IRS232A, the
Green
RS232 Out
LED does not blink
and
doesn’t control the device.
a. The IR receiver is not transmitting the command to the IRS232A unit. Check the IR Receiver and
the emitter going from the connecting block to the IRS232A IR IN (see
Figure 1
).
b. Make sure the proper RC68+ command is being sent to the IR Receiver. Use an RC68+
programmer remote set to the proper code group.
c. Verify the proper Code Group Setting in the Dragon Drop-IR™ project.
d. Verify that ‘an actual RS232 command string is programmed in the Dragon Drop-IR™ project
under that trigger.
