A 4mm Grounding Terminal Stud is located on the TimeProvider 500’s front panel.
The grounding terminal is marked with the universal ground symbol.
RS232 MGMT Serial Port
The DE9 connector labeled RS232 MGMT provides a local serial connection to the
TimeProvider 500. 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
Establish Serial Communication , on page 40 for default settings.
