order shown above. However, not all cards can be installed in all slots. Your local Spectracom
Sales Office will gladly assist you with the optimal option cards selection for your application.
The DC Power port connector is only installed if your unit was ordered with a DC input power
option. Other optional input/output connectors depend on the installed option cards.
Note: DC input power does not have an ON/OFF switch.
The ACPower connector is the input for the ACpower and provides an ACpower
ON/OFF switch. This connector assembly is only installed if SecureSync was ordered
with AC input power option.
The Ethernet connector provides an interface to the network for NTP synchronization and
to obtain access to the SecureSync product Web UI for system management. It has two
small indicator lamps, “Good Link” (green LED), and “Activity” (orange LED). The “Good
Link” light indicates a connection to the network is present. The “Activity” light will illu-
minate when network traffic is detected.

The USB connector is reserved for future expansion.
The 1PPS BNC connector offers a once-per-second square-wave output signal. The 1PPS
signal can be configured to have either its rising or falling edge to coincide with the sys-
tem’s on-time point.
The 10 MHz BNC connector provides a 10 MHz sine-wave output signal.
The optional ANTENNA connector is a type “N” connector for the GNSS input from
your GNSS antenna via a coax cable. This connector will only be present if the stand-
ard GNSS receiver, or the optional SAASM GPS receiver module are installed.
1.5 Option Cards
Option Cards are circuit boards that can be installed into a SecureSync unit in order to add
input and output functionality. Installation is normally done in the factory when the unit is built.
Many cards, however, can be retrofitted in the field by qualified customer personnel (see
"Option Card Field Installation Instructions" on page351).
