Power Connector
A Molex-style connector labeled Power is used to provide -48/-60 nominal volts DC
(labeled Power). When the unit is successfully powered, the PWR LED near the
center of the panel will illuminate green. If the power connection is reversed, the unit
will not be damaged, it simply will not power-up. Startup power will be < 17 watts
and steady-state power is (nominal 25 °C) < 9.5 watts.
The TimeProvider 100 uses –48/-60 nominal VDC power and is not equipped with a
power switch. Power to the unit must be controlled by a Branch Circuit Over-Current
Protection Device to the DC power main.
Warning: To avoid serious personal injury or death, exercise caution
when working near high voltage lines and follow local building
electrical codes for grounding the shelf.
RS232 Serial Port
The DE9 connector labeled RS232 provides a local serial connection to
TimeProvider 100. Through this connection, a Command Line Interface (CLI)
provides configuration and status monitoring capability. The RS-232 serial port
connection is made through a DE9S female connector. This port allows you to
connect to a computer using terminal emulation software for remote monitoring and
control. When connecting to this port, use a shielded direct connect cable. See
