and date of the ES-185U. It does not update any other settings. The user should select the desired
timezone from the
Timezone drop down box. Timezone offsets are available in ½ our increments up to +/-
12 hours. If the TC89 output is used, the user may select 12 Hour or 24 Hou r format. The display can be
set to 12 Hour or 24 Hou r format. If an offset in seconds or milliseconds is desired, select the
corresponding offsets from the Second Offset and Millisecond Offset drop down boxes. The seconds
offset is up to +/- 2 seconds and the milliseconds offset is up to +/- 490 milliseconds. Click on Send
Settings to update the ES-185U if any settings were changed.
The SMPTE Settings tab allows the user to set the Mode, Date Format and Resync settings of the
SMPTE output. The Mode drop down box allows the user to select Drop Frame , Non Drop Frame , EBU
or Real Time modes. The Date Format drop down box allows the user to select the format of the user
bits. The available formats are Format L (Leitch Format), Format E (ESE Format M-D-Y), Format S
(SMPTE 309M), or DOY (1-366). The Resync SMPTE after a drift of: drop down box allows the user to
select the number of frames that the SMPTE output is allowed to drift before the SMPTE output is
resynced to GPS. The user may select 3, 4, 5, 6, 7, 8, 10 or 12 frames. If the user would like to have the
SMPTE output resynced to GPS at a specific time, the
Enable SMPTE Resync at: box should be checked
and the appropriate time should be entered. The Resync SMPTE Now button resyncs the SMPTE output
to GPS when the button is clicked. If any settings were changed, click the Send Settings button to update
the ES-185U.
The Relay Events tab allows the user to program up to four relay closures. Option HR is required in order
to have a relay closure occur. Each event may be enabled or disabled by checking or unchecking the
Enabled box corresponding to each event. The user may program each event using the Min:Sec boxes
corresponding to each event. The events occur every hour since only minutes and seconds may be
programmed. Click the
Send Settings box to update the ES-185U if any changes have been made.
The DST Settings Tab allows the user to set up the DST feature. Check the Auto DST box in order have
the ES-185U automatically compensate for changes into and out of Daylight Savings Time. The DST
adjustment is according to the standards used in the United States and switches at 2:00 AM. The
Default
Dates account for the changes to the DST dates that will take place in 2007. The user may use the
Default Dates or the Custom Dates . To change the Custom Dates , click the Edit Custom Dates button.
The Send Settings box allows the user to update the ES-185U as has already been described. The user
does not need to click Send Settings after making changes in each tab. The Send Settings box may be
clicked after settings have been changed in all three tabs. The Set to Defaults box allows the user to
reset the settings of the Master Control Panel software and the ES-185U to the factory defaults.
Clicking on the Help Menu Item at the top of the Master Control Panel windows displays a help file for the
Master Control Panel software. The Hide link near the top of the window minimizes the Master Control
Panel window to an icon in the system tray. Click on the icon to restore the Master Control Panel window.
5.4 Option NTP Setup
Option NTP allows the ES-185U to act as a network time server. The Master Control Panel software, a
web page interface or a telnet session may be used to set up the ES-185U when option NTP is ordered.
When option NTP is ordered, the ES-185U needs to be assigned a permanent IP address. This can be
done using DHCP (Dynamic Host Configuration Protocol) or by using a fixed IP address. Both methods
are described in this section. Only one method needs to be used to assign the ES-185U an IP address.
Before powering up the ES-185U, connect the unit to the network and connect the antenna to the TNC
connector on the back of the unit.
When the ES-185U is shipped from the factory, the unit is already set up for DHCP Setup mode. If the
network has a DHCP server, a dynamic IP address will automatically be assigned to the ES-185U when
the ES-185U is first powered up (the ES-185U should be connected to the network before the initial
power up). Check the DHCP table in order to determine what IP address the ES-185U was assigned. If
you are unsure about how to check the DHCP table, refer to the documentation of the network router or
talk to your network administrator. The next step is to assign a permanent IP address to the ES-185U by
following the steps in the Permanent IP Address Assignment section (5.4.3).
If the unit is powered down in the future and powered back up, the ES-185U remembers the permanent
IP address it was assigned. The only time a new IP address is assigned is when the Reset button is
pressed for more than four seconds, thus initiating either the DHCP Setup or the Fixed IP Address Setup
procedures as described in the following sections.
If your network does not have a DHCP server, refer to the Fixed IP Address Setup section (5.4.2).
