EcoWatch for Windows Section 4
• Port Parameter Setup
These include the most common settings for each communication port.
These settings are Baud Rate, number of Data bits, and Parity. These
settings must be identical to the settings on the device that is connected to the
port. You may choose independent settings for each communication port.
• Protocol
You may choose Kermit, Xmodem or Xmodem 1K protocol for file transfer
through the communications port. 6820, 6920, 600R, 600XL, 600XLM and 6600
sondes use only Kermit protocol.
• Handshaking
You may choose Xon/Xoff, or RTS/CTS, or Both or None. Xon/Xoff is often
referred to as software handshaking and RTS/CTS as hardware handshaking. If you
are using a YSI sonde select Xon/Xoff. Modems usually require RTS/CTS.
• Modem Setup
This is where you enter the settings for your modem. Note that you can have several
modems, each on separate COM ports, and each with its own settings.
If a modem is selected for a particular COM port, then every time that port is
opened, EcoWatch will attempt to initialize a modem on that port. If the attempt
fails, then EcoWatch will open a terminal window and you can communicate to that
port with the computer keyboard. This can be very helpful in troubleshooting a
connection to your modem or in determining exactly which settings work with your
modem.
