Device Identify
This action page provides the instrument’s identification information: the IP Address, Hostname,
MAC Address, and the status of the Indicator LED. By clicking the
Identify button, the LAN LED
will flash green in order for the user can identify which instrument is being commanded. To return
the LED to its normal mode of operation, click on the
Stop Identify button.
Time Configuration
This entry page is used to change the time configuration of the EX10xxA. As the EX10xxA has no
notion of “wall clock” or calendar time and no battery-backed clock or any other mechanism to
retain time between reboots and power-cycles, the time must be set by the user. By default, the
instrument’s time and date at power-up are midnight, January 1, 1999 (as defined by the
microcontroller). Three time source options are provided:
PTP (Precision Time Protocol or
IEEE 1588 synchronization), SNTP (simple network time protocol), or manual . The default time
source is PTP.


Time Source : allows the user to set the EX10xxA’s date by entering the month (MM), day
(DD), and year (YYYY), respectively.

Set Time : for the PTP and Manual Time Source , allows the user to set the EX10xxA time
by entering the hour (HH), minute (MM), and second (SS), respectively. If the EX10xxA is
set as an IEEE 1588 Master, the hour should be entered using the 24-hour format.

NTP Servers : for the SNTP Time Source , allows the use to add/remove/save NTP servers to
which the EX10xxA will synchronize its time.

Time Status
: this section of the web page provides the mainframe’s current time
configuration settings.
Using PTP Time
To configure the EX10xxA to use PTP time as the clock source:
1) Set Time Source to PTP . The page will change so that it can be configured.
2) Click Submit to start using PTP time.
