For a detailed explanation of all commands available, please refer to the
chapter titled Alien Reader Protocol.
Network Communication
TCP/IP communication requires a network connection via the reader’s Ethernet
port and allows the reader to operate like a Telnet server.
This mode offers the same form of command line interaction with the RFID
Reader as the serial interface, but requires the RFID Reader to be configured for
and running on a network in order to use it.
By default, all RFID Readers are pre-configured to use DHCP when presented
with an Ethernet connection. However, you must first establish a direct serial
connection in order to learn the reader’s IP Address, or be able to detect
"heartbeat" messages sent out over the network by the reader.
Determine the Reader's Network Settings
Once your readers are set up and configured, you should either keep a record of
their addresses, or use some other mechanism for finding them, such as the
reader's Heartbeat messages (described later). Following are instructions for
querying the reader for this information.
ALR-9800
AND ALR-9770
All of the relevant network settings for the ALR-9800 and ALR-9770 readers are
displayed in the bootup sequence (see previous topic on Serial Communication),
notably, the IP Address and Subnet Mask.
A
LL OTHER READERS
There are five network commands that are used for querying the reader for its
network configuration.
get DHCP
get IPAddress
get Netmask
get Gateway
get DNS
Once you have the IPAddress and Netmask of the reader, you can connect to it
using TCP/IP.
Connecting via TCP/IP
The reader's TCP/IP interface mimics a basic telnet interface, so you can use
any telnet client to connect to the reader. Windows users can use the telnet
command at the command prompt or "Start -> Run" window:
telnet <ipaddress> <command port>
For instance, in the earlier example, the command would be:
telnet 10.9.8.10 23
