Safran SecureSync 2400 - Connecting Inputs and Outputs; Connecting Supply Power

When connecting directly to a stand-alone PC, use a network cable.
Connect the cable to the NIC card of the computer.
Since no DHCP server is available in this configuration both
SecureSync, and the PC must be configured with static IP addresses
that are on the same subnet (10.1.100.1 and 10.1.100.2 with a subnet
mask value of 255.255.255.0 on both devices, for example).For more
information on configuring static IP addresses, see "Assigning a Static
IP Address" on page66.
On Eth0: Once the unit is up and running, verify that the green link light on the
Ethernet port is illuminated. The amber “Activity” link light may periodically illu-
minate when network traffic is present.
2.8 Connecting Inputs and Outputs
SecureSync can synchronize not only to an external GNSS reference signal, but
also to other optional external references such as IRIG, HAVEQUICK and ASCII
inputs (in addition to network based references such as NTP and/or PTP).
At the same time, SecureSync can output timing and frequency signals for the
consumption by other devices via the same formats as listed above.
E X A M P L E :
With the available IRIG Input/Output option card module (Model 1204-05) installed in an
option bay, IRIG time code from an IRIG generator can also be applied as an external ref-
erence input (either in addition to, or in lieu of GNSS, NTP, user set time and other avail-
able reference inputs).
To use e.g., an external IRIG reference, connect the IRIG time source to the BNC
connector “J1” on the optional IRIG Input/Output module. For additional inform-
ation on optional connectivity, such as pinout tables, signal levels and other spe-
cifications, see "Option Cards" on page361.
Note that some option cards offer both input and output functionality, while oth-
ers offer only one or the other.
2.9 Connecting Supply Power
Depending on the equipment configuration at time of purchase, SecureSync may
be powered from different sources.
