Editing a Port's Properties: TNCs and Modems

To edit the properties of a PE Pro radio port, use the the list on the Radio Port Manager screen to first select (or highlight) the port to edit. Then, from one of the menus, select Edit: Properties or use the Edit Port Icon . The Properties for Port# window will then appear. Slightly different screens are used for:

  TNC and Modems (below)
  Sound Cards
 

TNC and Modem Properties

The radio port properties for a TNC or modem are initially made when you run the New Port Setup wizard. The first time you call up the properties screen for a TNC (as shown below), you are seeing the settings that were made when you ran the wizard. (The properties screen for modems looks nearly the same as that for TNCs.)

Additional information about editing each setting can be found below the picture.

Note that there is second tab in this window labeled TNC Commands. Selecting this tab brings up a screen with more TNC settings, such as the 'on air' baud rate, number of reties, TXDelay, etc. These settings are discussed on a separate TNC Commands Help page.

Top left:

  • Select Port - use the drop-down list to select the RS-232 serial or parallel port where the TNC or modem is attached to the computer.
     
  • Serial Port Baud Rate:  specify the baud rate to be used for computer-to-TNC communications on the RS-232 port, i.e. ABAUD or TBAUD in some TNCs. (Note: this is not the 'on air'/packet transmission baud rate used by the TNC/radio to send packets, i.e. HBAUD in some TNCs.)

    The serial port baud rate must match the rate already set in the TNC. If you see unreadable characters from the TNC, then you probably have chosen an incorrect serial port baud rate on this screen.

    External Modems
    - for a Baycom use 1200; for YAM set it to 9600.

Middle:

  • TNC Type - use the drop-down list to select your TNC or modem. If your TNC or modem is not listed, select a similar model or a generic type, such as TNC2.
     
  • TNC Sub-Type  - PE Pro will suggest a special KISS mode based on its knowledge of known TNCs. For others, if you are not sure what to do, select "KISS Simple".

Right side:

  • TNC Control Commands: IniKiss1, IniKiss2 IniKiss3 - PE Pro works with all TNCs by placing them in KISS mode. For known TNCs, PE Pro will suggest the KISS commands as shown in the IniKiss1, IniKiss2, and IniKiss3 fields.

    You can override/change these commands by entering your command in place of the suggested command. Commands are executed in the order shown, i.e. InitKiss1 is first. Delete any command that is not needed. To restore the default commands, re-select the TNC Type.

    Exit KISS on exit - check-mark this if box if you would like PE Pro to take the TNC out of KISS mode when PE Pro shuts down. It knows the command (s) to do this. Left unchecked, the TNC will remain in KISS mode when PE Pro shuts down.
     
  • Number of Ports - some TNCs have multiple ports to connect to multiple radios. PE Pro will select the right number of radioports for known TNC types. . For dual or quadruple port TNCs, PE Pro creates additional radio ports.
     
  • TNCs only: Auto Settings and Default - click these switches to automatically set or return to the known KISS commands, i.e. IniKiss1, IniKiss2, and IniKiss3.

Bottom left:

  • Radio Port Friendly Name - enter a descriptive name of your choice to help identify each radioport available. You might enter the band or frequency, baud rate, and/or radio, e.g.: VHF 1200 Kenwood V7A.

    PE Pro will append your Friendly Name to the TNC device name and the PTT control port when creating a radio port description, e.g. KPC3+ on COM1: VHF 1200 Kenwood V7A
     
  • Ports KISS ID - these fields are automatically assigned by PE Pro and normally should be left at the default settings. Change them only if you understand KISS port assignments and have a need to change them.
