Page 3: Overview
1. Overview This manual is for both the AL205R and AL205B modems. The AL205R (repeater) is a component of an ALERT2 system consisting of LoggerNet ALERT2 Admin, AL205B (base), and AL200 (encoder) or AL205E (encoder). The AL205R can be configured to support repeating of ALERT2 messages and as a backup base and decoder of received ALERT2 messages. -
Page 4: Power
USB flash drive is also used to install a firmware update. GPS antenna must be connected for proper time sync. GPS is required for the AL205R. NTP can be used instead of GPS in a AL205B, but time will be less accurate due to NTP jitter. -

ASCII format (N, P, S, C messages); ships with at least 8 GB USD card LEDs: Power, Bit Sync, Frame Sync, GPS On, Clock Sync, Tx Radio Power, Transmit, Serial 1, Serial 2, Serial 3 AL205R / AL205B ALERT2 Repeater / Base... -
Page 7: Configuration
A2Control are provided on the product webpages (www.campbellsci.com/al205r or www.campbellsci.com/al205b). 1. Connect your computer to the console port on the AL205R/AL205B using a USB cable. 2. Apply power to the AL205R/AL205B. 3. Launch A2Control. The following warning is displayed if the versions do not match. - Page 8 When A2Control begins communicating with the AL205R/AL205B, it will display the firmware type and version, and, if the AL205R/AL205B is connected to the network, the device IP address. NOTE: A2Control also can connect to the AL205R/AL205B remotely using TCP/IP by choosing network connection in the serial port drop down menu instead of a port number.

Page 11: Transmitting Data
The AL205R/AL205B receives and decodes ALERT2 data when powered. When the AL205R/AL205B finds a valid Bit Sync pattern in the incoming audio, it turns on the Bit Sync LED and begins listening for a valid Frame Sync pattern (which should immediately follow the Bit Sync). -
Page 12: Pass Reject List
FIGURE 3-1. Messages displayed on A2Control 3.3 Pass reject list The AL205R repeater firmware supports up to two different pass or reject lists for determining the messages to repeat. Before a message is repeated, it is checked against all active address lists. -

2. Connect the AL205R/AL205B to power. 3. Insert the USB thumb drive into the USB port of the AL205R/AL205B. 4. Wait more than two minutes for the AL205R/AL205B to recognize the USB thumb drive and start the firmware update. The Bit Sync LED flashes rapidly while the system logs are copied from the AL205R/AL205B (see Downloading ALERT2 data (p. -
Page 14: Remote Update
Update the AL205R/AL205B remotely over a TCP/IP networks using the SFTP protocol. Campbell Scientific recommends using FileZilla as an SFTP client (https://filezilla-project.org). Remote access to the AL205R/AL205B is disabled by default. To enable it, launch A2Control software, click the gear icon, click the IP Settings tab, and set the Network Password. -

USB flash drive. The AL205R/AL205B copies ALERT2 output files to that folder if it fined it. The AL205R/AL205B must be powered for at least two minutes for it to register the USB flash drive. -
Page 16: Loggernet Alert2 Administration Utility
5.3 LoggerNet ALERT2 Administration Utility LoggerNet can access the AL205R/AL205B ALERT2 and ALERT concentration data by using the LoggerNet ALERT2 Administration Utility in LoggerNet Admin. Usually, the AL205R/AL205B connects to the computer using TCP/IP and the LoggerNet call-back functionality, but the AL205R/AL205B can connect directly to a computer serial port. - Page 17 In the TCP Callback Port field, enter an open TCP/IP port number. TIP: Remote access to this port may require opening a port in the server firewall. Contact your IT administrator for help. AL205R / AL205B ALERT2 Repeater / Base...

Page 21: Port Descriptions
Click Write To Device to write the new setting to the AL205R/AL205B. 11. Return to ALERT2 Administrator and setup new ALERT2 stations and Sensor reports (see ALERT2 Administrator Help for more information). 6. Port descriptions The AL205R/AL205B has three serial ports with configurable functionality. The serial ports operate at RS-232 line levels. - Page 22 Serial port settings can be configured using the ALERT2 IND API or by using the AL205R/AL205B configuration menu. The AL205R/AL205B implements version 1.0 of the ALERT2 IND API. Default serial port settings are the following: Table 6-2: Default serial port settings...
