To switch the selection:
1. Press the down arrow to display the other option and then press Enter. You must enter
a passcode, which is 369369 for all ADL radios.
2. Press the right arrow to display a 3 on the second row.
3. Press the down arrow to display a 6.
4. Press the left arrow to display a 9.
5. Repeat Step 2 through Step 4. When you see 369369 displayed on the second row of
the LCD, press Enter; the keypad’s ability to configure the radio is changed. You can also
use the ADLCONF software to enable/disable the Edit Config function in the radio. Select/
clear the Enable check box in the Advanced menu of the Serial Interface screen.
Scrambling
To demodulate a digital transmission, a receiver must synchronize itself with the
transmitter. This can be hard to do when the transmitter 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 is expecting this, it can more quickly
synchronize itself with the transmission. This is essentially what Scramble Control does
and why we recommend you leave it on for all radios. However, if some of the radios in
your system are not Pacific Crest or Trimble radios, you may need to turn Scrambling off.
Note - TRIMTALK v1 protocol requires Scrambling. With this protocol selected, you are
unable to turn scrambling off.
Forward Error Correction
Forward Error Correction places extra bits in the transmitted data so receivers can check
for transmission errors. Although data throughput is adversely affected, using Forward
Error Correction can greatly improve range and so is strongly recommended.
Note - The Forward Error Correction screen does not appear when using Trimble protocols
as they do not support forward error correction.
Previous Error
The radios perform a variety of power-up and run-time tests to ensure optimal operation.
Tests include environmental as well as electrical measurements designed to avoid
damage to the unit while maintaining adequate operation. In the event of an error
condition, an error code is displayed on the LCD screen and the Pwr LED flashes the
number of the error code (two flashes for Error Code 02, followed by a pause, two more
flashes, etc.). The following table lists the possible error conditions:
Code
Description
What to do
01
Input voltage is too high
Check battery or power supply voltage level; check power
cables; recharge or replace the battery; check the charger.
02
Input voltage is too low
08
Internal temperature exceeds limit
for operation
Place the radio in the shade; check the antenna and
antenna cables for damage or disconnection; set radio link
rate to 19200 to reduce the duty cycle.
