Indicator LEDs
LED
Description
Tx
Shows that the radio is broadcasting.
In most GPS RTK applications, the Tx LED flashes approximately once per second.
Pwr
Shows the power status and also provides a high and low external voltage supply
indicator.
When lit, power is turned on. If the power is too high or too low, the LEDs will flash
the number of the Error Code (see
page 20
). The PWR LED blinks when the external
voltage drops to a level determined using ADLCONF software. (The default
level is 10 VDC.)
If the PWR LED does not turn on/off when pressing the On/Off button on the radio’s front
panel, inspect the external voltage supply. The minimum voltage required by the radio is
9 VDC.
Rx
Shows that the radio 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 flashes
it means
Data packets received
. You can reset the meaning either through the radio or
with the ADLCONF software.
During normal operation, the Rx LED flashes at once per second to show reception of
transmissions from the transmitting radio. If the Rx LED is on continuously, a source of
interference may be affecting the radio’s ability to receive data.
To reduce or eliminate the interference, reposition the antenna, or change to another
channel at both the transmitter and receiver.
PGM
Can be programmed to behave in user-definable ways. For more on programming contact
your Pacific Crest dealer.
Serial Port
The ADL Sentry supports one full RS-232 data port on an 8-pin I/O port. This port is
used to receive or transmit data in “data mode.” Attaching the ADL Sentry to a source of
power and a source of data is all you need to do to put Port 1 into “data mode.” Port 1 may
also be used in “command mode” to configure or troubleshoot the radio. To put Port 1 in
“command mode” apply power to the radio and connect it to a PC running ADLCONF
configuration software. Contact Pacific Crest Sales for information on incorporating into
your own software application a set of RS-232 commands for communication with the
ADL Sentry.
Security code
You can use the ADLCONF software to configure ADL radios to send and receive
encrypted data via the Transparent EOT/EOC or Packet Switched protocols. When
an ADL Sentry radio is programmed for encryption and is set to one of these three
supporting protocols, only similarly configured radios will be able to communicate with it.
Note
– With the Security Code feature on, the radio will be unable to communicate with
other radios that are not set to use the same code. When you enable this feature for one radio,
therefore, you should enable it for all the radios in the same communication network. ADL
radios with button/LCD interfaces can turn the Security Code feature on or off in the field, but
all other Pacific Crest radios, such as the ADL Sentry, must be attached to a computer running
the appropriate configuration software to disable the Security Code feature.
