GET TIMESERVER
SET TIMESERVER
The reader uses the Internet to accurately set its internal clock every time it is
rebooted. The protocol it uses is called the Daytime Protocol (RFC-867) which
typically returns the time in UTC format.
In order to use this feature, a TimeServer must be specified. This is the network
address of a machine that is constantly running the Daytime Protocol. In the US
there are a number of machines owned and operated by the Government
explicitly providing the time and date to Internet users.
• By default the reader is configured to connect to one of these machines on
boot-up to get the current time.
• For a more in-depth description of this server, and a list of other publicly
accessible Daytime Protocol Servers, see:
http://www.boulder.nist.gov/timefreq/service/its.htm
• The default setting for this command is 132.163.4.101, a primary NIST
network time server. Some alternative time servers are:
time-a.nist.gov / 129.6.15.28
time-b.nist.gov / 129.6.15.29
time.nist.gov / 192.43.244.18
NOTE: After making changes with this command, you must reboot the reader to
implement the changes.
Example
Command
Response
>Get TimeServer
>TimeServer = 129.6.15.28
>Set TimeServer = 129.6.15.28
>TimeServer = 129.6.15.28
The TimeServer is only used once when the reader is booted up. A message in
the boot sequence (sent out to the serial console) indicates success or failure of
this option.
For example, a successful boot sequence will report the following messages to
the serial console:
Booting Alien RFID Reader
Boot> Boot Level 1 (Console Communication) : Success
Boot> Boot Level 2 (Reader Communication) : Success
Boot> Boot Level 3 (Tag Manager) : Memory for 1000 Tags
