b)
Connector or wire problem. In this case, disconnect the instrument from the PC
c)
L loose contact or jamming.
Clear
a)
Make the remote control address and baud rate the same on the PC and the
instrument.
b)
Test the signal wire between the instrument and the PC. The TXD to GND terminal
should have a voltage of -8V to -12V.
c)
The receiving data may have problems, even if the remote control port works
properly. This may be due to loose contact between the port and the cable connector.
It can also be caused by jamming from the operating environment. In this case, make
well connect of the port and the cable connector. Also, use a shielding wire and make
the shielding wire grounded to earth.
