  • Optional ALERT Receive Capability

 


 

DESCRIPTION:

The ALERT2 Demodulator - 1002 Series receives ALERT2 messages from remote sensing stations and passes them to a base station computer equipped with an ALERT2 base station software program. Data is exported simultaneously out both a Serial data port and an Ethernet port. If the ALERT2 Demodulator is equipped to receive ALERT data, the "Active" LED will illuminate when data is being received. ALERT2 incoming data is indicated by the ALERT2 Demodulator's "Frame" and "Bit" LEDs.

In addition to receiving and demodulating ALERT2 data, some ALERT2 Demodulators in the 1002 Series include an internal ALERT receiver/decoder to facilitate continued reception of ALERT data. The ALERT data is received by the ALERT2 Demodulator on a dedicated radio and can utilize a separate frequency or share a frequency with the ALERT2 data. Depending on the specific ALERT2 Demodulator configuration ordered, the output format of the ALERT data will either be Serial or Ethernet.

A micro SD card in the ALERT2 Demodulator stores a log file of all received ALERT2 messages. The ALERT2 Demodulator creates a new file each day at midnight UTC time. The data may be accessed via an Ethernet connection.

In addition to streaming ALERT2 data to a terminal program or ALERT2 base station software program, the ALERT2 Demodulator's Ethernet port can be used to retrieve log files and set up files. If permissions have been set up, the ALERT2 Demodulator can also be used to modify the log file name or other setup files. Connection to a Server through the ALERT2 Demodulator's Ethernet port will also provide an accurate time stamp indicating precisely when each ALERT2 message was received.

The ALERT2 Demodulator's Serial port can also be used to send data to a terminal program or ALERT2 base station software program.

Up to 8 receive frequencies specified by you will be programmed into your ALERT2 Demodulator at the factory, prior to shipment.
