If you want to exit LSUB mode to "fine tune" parameter settings (or for any other
reason), the Command mode of the modem can be regained by using the transparent data
escape sequence, i.e., by sending a series of three control-Cs (unless a different control
character has been defined). (See TRANS command in the Reference Manual).

CONFIGURATION
Following are examples of programming the TALON UDC for different types of
applications. Before programming the unit do the following preliminary setup:
•
Connect the ANT port to a 50 RF dummy load of adequate power handling
capability, a service monitor or power meter, or an antenna
•
Connect the Serial I/O port to a PC or terminal with an RS232 straight through cable,
not a null modem cable. The unit is considered DCE
•
If there is a GPS antenna connector, connect a GPS antenna
•
On the PC or terminal open a communications program, such as HyperTerminal™
found in Windows™. Set communications for the correct COM port number,
typically COM1, COM2, COM3, or COM4; baud for minimum of 1200 to maximum
of 19200; no parity; 8 data bits; and 1 stop bit. Baud should be set to rate intended to
be used in application
•
Apply dc power to the unit
•
Unit will come up in ABAUD (autobaud) mode. Push the asterisk key
•
Unit will request call sign (MYCALL)
Enter your assigned callsign and SSID (number from 0 to 8191).
•
The VDT will display the sign on message
