LPT2, and the RPI can be connected to serial port
COM1 or COM2. There is also an option to either
save or not save the selected configuration for the next
time that the program is run. The screen displayed by
this function is shown below. Use the arrow keys and
spacebar to display the desired configuration and then
press Return with “Save Changes” highlighted to
select that configuration.
4.5.9 CONFIGURATION FILE UTILITIES
This function is selected to save, copy, rename, or
delete a radio configuration file. The “Save” function
saves the current configuration file to disk. This func-
tion should be used periodically while editing a file to
ensure that all data is not lost if a power failure occurs
or program execution is interrupted for some other
reason.
The copy, rename, and delete functions are
performed on disk files. The files in the current direc-
tory are listed and then the arrow and Return keys are
used to select the file. When copying a file, it must be
given a new name and/or destination in the destination
box. The screen displayed by this function follows.
4.6 MODIFY RADIO FILE MENU
4.6.1 INTRODUCTION
The Modify Radio File screen is used to select
other screens which program the various types of
configuration information. This screen is shown in
Figure 4-3, and the screens it selects are described in
the following information. The Main Menu “Set Up
New” and “Modify Current” configuration file func-
tions described in Sections 4.5.2 and 4.5.4 select this
screen. The following keys have special functions in
this screen. Other special keys are described in
Section 4.3.2.
F5 (Show Banks) - Displays the alpha tag of the banks
programmed in the current file (see Section 4.6.6).
F6 (Show Systems) - Displays the alpha tag and type
of all systems programmed in the current radio file.
“L” = LTR and “C” = conventional.
4.6.2 EDIT MAIN RADIO PARAMETERS
General
This function selects the Main Radio Parameters
screen which is used to program transceiver parame-
ters that are the same for all systems. This screen and
a description of each parameter it programs are
described in Table 4-1. Parameters followed by “N/A”
(not applicable) are not available with this transceiver.
I/O Options (F3)
Pressing F3 displays the I/O Interface Options
screen. Refer to Section 4.9 for more information.
Channel Table (F6)
All channels to be assigned to LTR systems and
conventional groups must be entered into a channel
table. This table is displayed by pressing the F6 key
from Main Radio Parameters menu (an example
follows). With high tier models, up to three tables of
channels can be programmed, so a menu is first
displayed to select which table to program. The
channel number assigned in this table is used to assign
that channel in the system or group programming
screen (FCC or programming channel numbers are not
used). Up to 126 channels can be programmed in each
table. Therefore, up to 126 different channels can be
programmed with low tier models and up to 378 with
high tier models.
The receive frequency is entered and then the
transmit frequency is automatically displayed. With
UHF and 800 MHz channels, the bandwidth (12.5 or
25 kHz) must also be entered. The 900 MHz channels
are always 12.5 kHz. Conventional mode talk-around
