COM1 communication mode DIP switch (SW2)
Open the communication housing case and adjust the DIP switch as follows:
The baud rate is automatically detected and adjusted within the range of
IMPORTANT
4800 to 38400 bps. No separate speed setting is required. Once a speed is
assigned, it is maintained until there is no communication for more than
one minute. Then, the speed is automatically detected and configured
again.
The termination resistance is connected to the end of the communication
line to remove mutual communication interferences or signal distortions
that can occur between connected controllers and peripherals.
Use an external connector for termination for COM2 port.
