To connect the Scanner to Scanner:
Plug the male end of the RS232C straight interface cable into the
remote port on the rear of one of the two scanners. Then connect the
DB-9 to DB-9 null modem adapter to the cable. Plug the other end of
the null modem adapter into the other scanner.
(DB9 Gender Changers are also available at your local electronics
store.)
You can clone all of the programming of one UBC785XLT into another, including alpha tags,
delay settings, etc. After connecting the two scanners, turn the radios ON. Prepare each
scanner for clone mode as follows.
1. Press MENU.
2. Select 3:SYSTEM OPTION / 6:CLONE by rotating the VFO and pressing E.
3. Determine the scanner that has the frequency data that you want to transfer. This one
must be set up as the "Master Unit", and the other must be set as the "Slave Unit".
4. On the scanner that is the "Master Unit", select MASTER,
then press E.
5. On the scanner that is the "Slave Unit", select SLAVE, then
