2.1.2Necessary Equipment

The equipment you need to get started includes:

•Power source

•GPS antenna connection that supports 12 V

•An Ethernet LAN with one port available for TimeVault’s network connection

•An Ethernet cable with an RJ-45 connector for the NET Port (Category 5 Ethernet cable is recommended for 100Base-T operation)

•A separate analog phone line for the ACTS modem

•A cable with an RJ-11connector for the ACTS Port

•A set of network address parameters for the NET Port that delivers NTP time and allows remote control of the unit over the Internet

TimeVault requires a 12 V antenna and may severely damage any antenna that does not support 12 V. For non-standard antenna types, contact Symmetricom for assistance.

Optionally, you can add an RS-232 serial interface for local control using a terminal emulation program. This requires:

•A serial interface device, either PC or dumb terminal capable of 9600 8N1

•An RS-232 cable, and null modem connector, to connect the 9-pin D RS-232 port to the serial device

TimeVault is capable of basic operation without an RS-232 connection, and retains all configuration data in memory.
