Regional Information
Regional Information
The Astra reader is currently available in four different regional hardware configurations:
Astra North America
Astra Korea
Astra India
Astra Europe
The only difference between the different hardware versions is the frequency range they support and, in some cases, confguration for specific subsets of regulatory compliance in that region. The regulatory support and configuration details, if any, for each is defined
below. Each regional reader can be identified both through the Web Inteface Status Page
and by the
Model Number
on the reader’s lableling.
Astra North America

Astra-EU
Astra-EU readers support
ETSI EN 302 208-1 V1.1.1
(10-Channel with LBT Option) and
Revised ETSI EN 302 208-1 V1.2.1
regulations (4-Channel options).
The
allows you to configure the regulatory plan the Astra will use. The 4-
Channel plans are the current plans which should be used for most applications. The 10-
Channel is being made available for legacy installations.
Note
Switching between the 4-Channel plans and the 10-Channel plan requires a reboot.
Switching between the two 4-Channels plans does not.
Revised ETSI EN 302 208-1 V1.2.1
When using the 4-Channel Mode with a custom channel list the Astra will operate differently, according to the regulatory specification, based on the number of channels used:
Single Channel Mode
If only a single channel is moved to the
RF Channels in Use
field, the Astra will occupy the set channel for up to four seconds, after which it will be quiet for 100ms before transmitting on the same channel again.?
Multi Channel Mode
If more than one channel is moved to the
RF Channels in Use
field,.the Astra will occupy one of the configured channels for up to four seconds, after which it may switch to the next channel and immediately occupy that channel for up to four seconds. This mode allows for continuous operation, with no quiet periods.
ETSI EN 302 208-1 V1.1.1
When using the 10 Channel Mode the integrated antenna will always be used for LBT.
This means that when configured for bistatic operation the external antenna will be the
Transmit antenna and the integrated antenna will be the Receive and LBT antenna. This is the reverse of the Astra-NA and Astra-KR which use the integrated antenna for transmit.

Networking the Reader
Networking the Reader
You can set up the Astra Reader to use either manual IP addressing or DHCP. By default, the Reader has automatic addressing enabled that boots up for a DHCP server.
DHCP can be used to automatically assign the Reader's IP address, subnet mask, default gateway, NTP Server, DNS server, and hostname. During the initial boot sequence, if the
Reader does not get a DHCP-assigned IP address, the static IP address 10.0.0.101 is assigned by default. However, the Reader will periodically check to see if a DHCP server is available.
The following section explains how to set up your PC and Reader for automatic DHCP configuration. This section also explains how to manually configure the Reader without a
DHCP server and how to use the ZeroConf protocol, Bonjour TM , for subnet Reader discovery, without a DHCP server.
Setting Up the Network Hardware
Whether you use DHCP or static network addressing, make sure that the network is connected before powering up the Reader. If the Reader does not automatically get the address from a DHCP server, then the static IP address 10.0.0.101, subnet mask
255.255.255.0, and gateway 10.0.0.1 is used.
Before setting up your network:
Connect one end of the Ethernet cable to the Reader and the other end to the
Ethernet switch or hub.
Check that all antennas are securely connected, and then power-up the
Reader.
Connect your PC to the same network as that of the Reader.
Note
Some older 10baseT network hubs do not work properly with the Reader. If you encounter connectivity problems, we recommend using nothing below 10/
100baseT hubs/switches.

Connecting to the Astra Serial Port
Connecting to the Astra Serial Port
Astra supports communication over its serial port to enable you to:
Access the boot logs.
Access the console for emergency recovery into Safe Mode.
Before you connect to the Astra serial port, ensure that you have:
A PC with a serial port.
A serial terminal program.
A serial cable.
Older PCs usually have a 9-pin serial port built in; however, modern PCs usually do not. If your PC does not have a serial port, you can add one. The easiest way to do so is by using a USB-to-serial adapter. Read the adapter's documentation for information about how to access the serial interface for your particular operating system (Windows often sees these adapters as "COM8" whereas Macintosh often sees them as "/dev/ tty.usbserial0").
When you have completed setting up the serial port, you must set the following four parameters to allow the terminal program to talk to the Reader:
Data Rate: 115200
Parity: None
Data Bits: 8
Stop Bits: 1
The procedure for setting these parameters is different for each terminal emulation program. Check the documentation for your program for information on setting these parameters.
Once you have set up the serial connection, reboot the Reader, and the boot logs begin to display. If not, recheck the terminal program configuration and try again.

Using GPIO
Using GPIO
The Astra Reader includes 12-pin GPIO screw terminal connector. This connector is used to support four opto-isolated general purpose inputs and four opto-isolated general purpose outputs. The values of the GPIO lines can be Get and Set using the RQL and the
C-API interfaces. See the respective guide for more details.
There are four open-collector outputs and four open-collector inputs. The outputs sink up to 50mA, but do not source any power, external power is required.
Note
Devices using the GPIO lines must be NPN type devices and require external power supply. The GPIO lines simply act as a switch.
In addition to the Input and Output lines, pins 10 and 11 duplicate the information provided by the reader's activity LED indicating reader health and RF activity. RF activity can also
be monitored in this connector. See the section Interpreting the Reader Indicator LED for
information about Reader activity and status.

Raw Tag Data
Depending on the fields included in the query, you can display a variety of tag data: id: Tag id (in hex) and trailing 4-digit (16-bit) CRC cyclical redundancy check. read_count: Number of times the tag was seen during the query.
protocol_id: GEN2 = 12.
antenna_id: From 1 to 2 depending on which antenna saw the tag.
frequency: Frequency in KHz at which the tag was seen, in hop table.
timestamp: Unix time in seconds and microseconds from 1-1-1970 when tag was seen. For example: 3004832.188394
Write Page
The Astra Write Page, as shown in
, enables you to replace the ID or data that is encoded on a tag.
Consider the following guidelines when writing to tags:
Always place a tag 0.3-0.6m (1-2 ft) from the antenna when writing. The tag may be damaged if it is too close to the antenna.
The ID to be written must match exactly the number of hexadecimal characters,
(numerals from 0-9 and letters from A-F) specified by the tag's protocol.
Example: 96-bit tag IDs are 20 hexadecimal characters long.
The Clear Output button clears the data displayed.
Place only one tag in the antenna's field when writing. If multiple tags are present, they may all be encoded with the same EPC data, or the write may fail unless the RQL query specified indicate a specific tag to be written to. See the
RQL documentation for more information.

Using Safe Mode
There are two reasons to enter Safe Mode:
To perform a firmware update for repairing a corrupted filesystem.
To change settings that prevent the Reader from operating normally.
Note
Both of these tasks can be performed through the web interface.
Safe Mode is used to recover from errors that prevent the Reader from operating in normal mode. In Safe Mode the Reader is configured with a static IP address of
10.0.0.102. Safe mode uses the following network settings:
IP Address: 10.0.0.101
Hostname: Astra
Although the browser-based interface pages are displayed in red when operating in safe mode, the Reader is still functional though it cannot read or write tags. The web server, telnet server, and SSH (Secure Shell) server run in Safe Mode, however none of the
RFID features are activated.
In most cases, after starting in Safe Mode, the Reader will need to be reconfigured for operation with the Reader application, after starting in Safe Mode.To communicate with the Reader in Safe Mode, your PC must have an IP address and subnet mask that are compatible with the Reader settings. You can then reconfigure the desired settings through the web interface. After you have completed the maintenance, restart the Reader to activate the changes.
For example:
IP address: 10.0.0.101
Netmask: 255.255.255.0

Reader RF Power
Reader RF Power
If you are using an external antenna during initial installation, you must properly configure to use the correct RF power to comply with FCC regulations. The software limit does not allow the power to be set higher than 30.0 dBm. Therefore this particular antenna configuration will comply with FCC regulations.
For the external antenna, the maximum RF power for compliance is determined from antenna gain and antenna cable loss using the following formula:
Pmax = 36 dBm - Antenna Gain + Cable Loss
Reader RF Power Example
The antenna provided by ThingMagic that is listed in the appendix has the following features:
Antenna that has a maximum gain of 6 dBi
Cable that has a loss of 0.6 dB
Using the formula listed above, you have the maximum RF power is (36- 6 + 0.6) = 30.6 dBm. For more information about setting the RF power, refer to

Variables Affecting Performance
Reader performance may be affected by the following variables, depending on the site where your Reader is being deployed:
Environmental
Reader performance may be affected by the following environmental conditions:
Metal surfaces such as desks, filing cabinets, bookshelves, and wastebaskets may enhance or degrade Reader performance.
Antennas should be mounted far away from metal surfaces that may adversely affect the system performance.
Devices that operate at 900 MHz, such as cordless phones and wireless LANs, can degrade Reader performance. The Reader may also adversely affect the performance of these 900 MHz devices.
Moving machinery can interfere the Reader performance. Test Reader performance with moving machinery turned off.
Fluorescent lighting fixtures are a source of strong electromagnetic interference and if possible should be replaced. If fluorescent lights cannot be replaced, then keep the Reader cables and antennas away from them.
Coaxial cables leading from the Reader to antennas can be a strong source of electromagnetic radiation. These cables should be laid flat and not coiled up.
Astra User Guide
59
Mounting the Reader
Tag Considerations
There are several variables associated with tags that can affect Reader performance:
Application Surface: Some materials, including metal and moisture, interfere with tag performance. Tags applied to items made from or containing these materials may not perform as expected.
Tag Orientation: Reader performance is affected by the orientation of the tag in the antenna field. The ThingMagic antenna is circularly polarized, so it reads face-to but not edge-to.
Tag Model: Many tag models are available. Each model has its own performance characteristics.
Multiple Readers
The Reader adversely affect performance of 900 MHz devices. These devices also may degrade performance of the Reader.
Antennas on other Readers operating in close proximity may interfere with one another, thus degrading performance of the Readers.
Interference from other antennas may be eliminated or reduced by using either one or both of the following strategies:
Affected antennas may be synchronized by a separate user application using a time-multiplexing strategy.
Antenna power can be reduced by reconfiguring the RF Transmit Power setting for the Reader.
Note
Performance tests conducted under typical operating conditions at your site are recommended to help you optimize system performance.
