GPS RTK equipment is designed to func on with intermi ent gaps in the data. Heavy co-channel use may limit the ability
of the ADL Vantage/ADL Vantage Pro radio to transmit the required informa on. In areas of heavy co-channel usage, try
changing channels to a less used frequency.
Security Code
You can use the ADLCONF so ware program to confi gure your ADL Vantage/ADL Vantage Pro to send and receive en-
crypted data. When the radio is programmed for encryp on, the second line of its Security Code screen will say On (with
an asterisk). Only radios that support Pacifi c Crest protocols (Transparent EOT, Transparent EOC, Packet Switched) and are
programmed with this code will be able to interpret data sent by any of the radios. To turn the security code feature off ,
press the Up or Down arrow to display the Off op on and press Enter. to turn the security feature back on, select the On
op on. If the radio has not been programmed by ADLCONF for data security, you will not be able to select the On op on.
Note: If you program a radio to use the Data Security feature, it will not be able to communicate with any
radio that is not set to use the same code. So when you enable this feature for one radio it is a good idea to
enable it for all the radios you will use in the same communica on network. ADL radios with bu on/LCD
interfaces can turn the Data Security feature on or off in the fi eld, but all other Pacifi c Crest radios must be
returned to the offi ce to disable the Data Security feature using the appropriate confi gura on so ware.
Edit Confi gura on
The ADL Vantage/ADL Vantage Pro LCD display includes an Edit Confi g screen that indicates if confi guring the radio with
the keypad is Enabled or Disabled. The current selec on is displayed with an asterisk on the second row of the Edit
Confi g screen. To switch the selec on, press the down arrow to display the other op on and press the Enter bu on.
You are now instructed to input a passcode, which is 369369 for all ADL radios. To input this code, press the right arrow
to display a 3 on the second row. Then press the down arrow to display a 6 and the le arrow to display a 9. Press the
right, down and le bu ons a second me in sequence. When you see 369369 displayed on the second row of the LCD,
press Enter and the keypad’s ability to confi gure the radio is changed. You can also use ADLCONF to enable/disable the
Edit Confi g func on in the ADL Vantage/ADL Vantage Pro by checking/unchecking the Enable fi eld confi gura on box on
the Serial Interface screen’s Advanced menu. The RX LED fl ashes to indicate that the ADL Vantage/ADL Vantage Pro is
receiving signals from another radio or from a source of interference. The default is Signal received, but you can reset the
radio so that when its RX LED fl ashes it means Data packets received. You can reset the meaning either through the user
interface or with ADLCONF confi gura on so ware. During normal opera on, the RX LED will fl ash at a once-per-second
rate indica ng the recep on of transmissions from the transmi ng radio. If the RX LED is on con nuously, then a source
of interference may be impac ng the ability of the ADL Vantage to receive data. Try reposi oning the antenna, or chang-
ing to another channel at both the transmi er and receiver to reduce or eliminate the interference, another radio or
from a source of interference. The default is Signal received, but you can reset the radio so that when its RX LED fl ashes

Scrambling
To demodulate a digital transmission, a receiver must synchronize itself with the transmi er. This can be hard to do when
the transmi er sends a long series of one’s or a long series of zeroes. But if every nth character in the transmission were
switched, a one to a zero or a zero to a one, and if the receiver was expec ng this, it could more quickly synchronize
itself with the transmission. This is essen ally what Scramble Control does and why we recommend you leave it on for
all radios. If you select a protocol type other than Transparent (EOT and EOC) or Packet Switched, Scrambling will auto-
