6.8 FAQ
1. Serial Port operation is out of order / cannot control the switching
Possible causes: The serial port is damaged or not connected properly, the serial
cables are not of the correct type, or the serial connection has not been initialized.
Solution: Make sure the RS232 ports are connected using a crossover / null modem
serial cable, and double-check the connection of the PC software serial port. See
Section 6.3.a for instructions on setting up the serial COM port.
2. Common troubleshooting
Power failure: Check the power fuses and power cabling.
Signal interference: Make sure the cables and plugs are firmly connected, the cables
meet the working requirements of your setup, the system is well-grounded, and the
AC power between devices have the same grounding system.
