2)
Connect the NetClock’s front panel Ethernet port to an available hub/switch on the network
with a standard network cable.
3)
Connect the DC power input jack to a standard AC outlet with the supplied power supply.
Verify the green Good Link lamp next to the Ethernet connector illuminates.
4)
From the network administrator, obtain an available static network IP address, the network
subnet mask and the IP address of the immediate gateway (if installed) if the subnet must
access the NetClock. This step is only necessary if you are not using DHCP.
5)
Assign the IP address, net mask and gateway settings by using the rear panel Serial
Setup Interface DB9F connector interfaced to a PC with the provided serial cable (PC
should be running either Microsoft HyperTerminal or ProComm). (Refer to
Options
for
more information). This step is only necessary if you are not using DHCP.
6)
Install the GPS antenna, surge suppressor, antenna cabling and GPS preamplifier if
required. If using a window-mount antenna (Model 8228), place the antenna in a window
that has no metallic tinting or screening in or on the glass and then place the unit in single-
satellite mode.
7)
Connect the GPS cable to the rear panel antenna input jack on the back of the NetClock.
8)
Verify the NetClock front panel Sync lamp illuminates green. Synchronization may take up
to 20 minutes (approximately).
9)
If supplied with Option 03 Dial-out Modem, connect the dial-out modem to the rear panel
Setup port. Change the console/modem mode of operation to Modem using the Web User
Interface.
10) Configure the NetClock front panel LCDs as desired (Option 02 only) using the Web User
Interface.
11) Interface the NetClock to wall display clocks and other peripheral devices as needed.
12) Configure each of the rear panel outputs to these devices for desired local times, baud
rates and Data Formats using either the Web User Interface or the serial setup port (Each
port is separately configured so each port used may need to be configured for your
desired configuration).
NOTE:
Unless you are using DNS in conjunction with DHCP (with the client configured using
the NTP server's hostname instead of IP address), DHCP must be disabled and the
IP address must be changed to a static address once the NetClock is properly
configured. Failure to do this will result in a loss of time synchronization if the DHCP
server assigns a new IP address to the NetClock. Verify your setup before
synchronizing the network PCs via NTP.
13) Synchronize the network PCs via NTP using the Ethernet port as desired. (Refer to
www.spectracomcorp.com
for assistance and refer to Table 2-1 for information regarding
local time.)
14) Review your security configuration settings.
