5.4.1 DHCP Setup (factory default)

This method of setting the IP address of the ES-185U can be used if the network has a DHCP
server. Using this method automatically assigns an IP address to the ES-185U.

When the ES-185U is shipped from the factory, the unit is already set up for DHCP Setup
mode. Connect the ES-185U to the network and then power up the unit. The DHCP server
should then assign the unit a dynamic local IP address. 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 last step is to assign a permanent IP address to the ES-185U by following
the steps under Permanent IP Address Assignment.

If the DHCP server did not detect the ES-185U, follow the procedure described here to set the
ES-185U in DHCP Setup mode and try again. The ES-185U should be connected to the
network during this process. Unplug the ES-185U for 10 seconds and power up to restore
normal operation. Then hold the Reset button (accessible from the rear panel) down until the
GPS Lock LED goes out (it will have been either lit or flashing, depending upon lock status).
This takes about 4 seconds. Then immediately release the button. If configuration is
successful, the GPS Lock led will begin flashing rapidly within a few seconds. Unplug the unit
for 10 seconds, then power up to restore normal operation. The DHCP server should then
assign the unit a dynamic local IP address. 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 last
step is to assign a permanent IP address to the ES-185U by following the steps under
Permanent IP Address Assignment (5.4.3).

5.4.2 Fixed IP Address Setup

If you don’t have a DHCP server LAN, you can configure the unit with a fixed IP address. The
unit will be set to a factory default address (192.168.1.50), which can be changed later
through a telnet session as described below. To start the fixed IP address setup, unplug the
ES-185U for 10 seconds and power up to restore normal operation. Next, hold down the
Reset button until the GPS Lock LED goes out (4 seconds) and then re-lights solid (another
2.5 seconds). Release the button. If configuration is successful, the GPS Lock LED will begin
flashing rapidly within a few seconds. Unplug the unit for 10 seconds, then power up to restore
normal operation. To change the IP address to its final value, follow the instructions described
here.

The NTP Port has been assigned a default IP Address of "192.168.1.50". In order to connect
to the device using telnet, you must set the IP address of the computer you use to connect to
the device to a value within the same subnet of the default NTP port address. (Please consult
with your network administrator if help is needed.)

Example: If you presently have a subnet mask of "255.255.255.0", then any IP Address
between the range 192.168.1.1 - 192.168.1.254 will work, excluding 192.168.1.50 which is the
default for the NTP port.

Next, follow the Permanent IP Address Assignment procedure (5.4.3). If the IP address of the
computer was changed in order to connect to the ES-185U, remember to change it back to the
original IP address after the IP address of the ES-185U has been changed.

5.4.3 Permanent IP Address Assignment

The Master Control Panel software, a web page interface or a telnet session may be used to
set up the permanent IP address of the ES-185U. Only one method is required. The user may
select the easiest method to do this.

5.4.3.1 Master Control Panel Software

Start the Master Control Panel software. If it has not been installed yet, see section
5.1 for instructions on how to install the software. When the Master Control Panel
software connects to the ES-185U through a network connection, additional tabs
appear in the Master Control Panel window. The additional tabs are 

NTP Settings

,

Broadcast Settings

 and 

Password

. The 

Primary Settings

, 

SMPTE Settings

 and 

Relay

Events

 tabs are the same as described in section 5.3. The 

PC Time Setting via RS-
