Configuring Modem Settings

See Certified Modems for information on certified modems that work with the KX III.

For information on settings that will give you the best performance when connecting to the KX III via modem, see Configuring Connection Properties.

• To configure modem settings:

1. Click Device Settings > Modem Settings to open the Modem Settings page.
2. Select the Enable Modem checkbox. This will enable the Serial Line Speed and Modem Init String field.
3. The Serial Line Speed of the modem is set to 115200.
4. Enter the initial modem string in the Modem Init String field. If the modem string is left blank, the following string is sent to the modem by default: ATZ OK AT OK.

   This information is used to configure modem settings. Because different modems have different ways of settings these values, this document does not specify how to set these values, rather the user should refer to the modem to create the appropriate modem-specific string.

   1. Modem Settings:
      • Enable RTS/CTS flow control
      • Send data to the computer on receipt of RTS
      • CTS should be configured to only drop if required by flow control.
      • DTR should be configured for Modem resets with DTR toggle.
      • DSR should be configured as always on.
      • DCD should be configured as enabled after a carrier signal is detected. (that is, DCD should only be enabled when modem connection is established with the remote side)
5. Enter the IPv4 modem server address in the Modem Server IPv4 Address field and the client modem address in the Modem Client IPv4 Address field.

   Note: The modem client and server IP addresses must be on the same subnet and cannot overlap the device's LAN subnet.

6. Click OK to commit your changes or click Reset to Defaults to return the settings to their defaults.
