The SL200 logger is designed to be connected directly to your PC’s 9 pin COM (serial) port. A 25 pin to 9 pin adapter may be necessary, if your computer does not have an available 9 pin port. The SL200 logger must be connected to a free serial port (a port that is not used by a modem, a mouse, or any other serial device). If the serial port was recently used for a modem or a mouse, Windows may still mark the port as busy. If the SL200Log software encounters problems detecting the logger, you may need to reboot your system for the logger to be correctly recognized.
When the SL200Log software needs to communicate with the SL200 logger for the first time, all the free COM ports on your computer are searched automatically for the presence of the SL200 logger.
