Download (to Radio) instructs the TDP-90 software to transfer the frequency data in the
list to the memory channels in the connected 8.33 kHz AM transceiver. The Dn icon
provides the same function in a single mouse click.
Upload (from Radio) instructs the TDP-90 program to wait for and read the channel data
from the memory channels in the connected 8.33 kHz AM transceiver. The Up icon
provides the same function in a single mouse click.
Com1 (2,3,4) selects the COM (RS-232 Serial COMmunications) port on your computer, to
which the transceiver is connected. On computers manufactured after 1990, COM 1 is
typically a 9 pin male "D" connector. COM 2 may be either a 9 pin male or 25 pin male "D"
connector. COM 3 and COM 4 are available in the TDP-90 software as a valid option,
although they typically exist only in a computer with a third party serial communications
card installed.
The COM port setting is automatically saved. The next time the TDP-90 software is
executed, the previously selected COM port will be used.
NOTE: ** The TDP-90 software assumes you have an available and properly configured
COM port, and assumes that a TSC-4400 transceiver is connected. **
