CHAPTER 2
INSTALLATION
2.0 GENERAL
The NTP Server is a self-contained chassis (desk top or rack mount) equipped with a bc620AT
Time and Frequency Processor, CPU Module and an Ethernet Module. This section details the
steps required to install the TYMSERVE 2000 Network Time Server.
2.1 ETHERNET CONNECTION
The Server provides a standard AUI connector on the rear panel of the unit. The Server is
connected to the network via this AUI connector. The connection can be made directly to a
multiport transceiver, or to a thick net or thin net MAU provided by the user.
The Internet address, subnet mask, default gateway, and Ethernet frame format of the
TYMSERVE must be changed by the user. Refer to Chapter 4 (Menu System) for details on
changing the TYMSERVE network parameters.
2.2 TIMING SOURCE
The TYMSERVE 2000 can use its internal clock as the timing source, but most applications will
require an external timing source such as time code or GPS. Refer to Chapter 4 for details on
selecting a timing source. Refer to Chapter 5 for details on connecting an external timing source
to the TYMSERVE 2000.
2.3 ANTENNA INSTALLATION (-GPS version only)
The most common difficulty encountered using GPS equipment is antenna position. The GPS
antenna must be located in an area which has a clear view of the sky. The GPS signals cannot
penetrate foliage or structures. It is strongly recommended that the user take the time to properly
position the antenna.
The GPS antenna is connected to the TYMSERVE 2000 rear panel connector labeled 'GPS
ANTENNA'. The GPS antenna connector is a 15 pin high density 'D' type connector.
