Ascii Time Code In/Out [1204-02, -04] - Safran SecureSync 2400 User Manual

The incoming input time information may be provided as local time, but System
Time may be configured as UTC time, so internal computations need to be per-
formed. With the Timescale field set to "Local", select the name of a previously
created Local Clock. The Time Zone and DST rules, as configured in the Local
Clock will be applied to the front panel time display. Refer to for more inform-
ation on Local Clocks.
Offset: Provides the ability to account for HAVE QUICK cable delays or
other latencies in the HAVE QUICK outputs. The Offset values are entered
in nanoseconds (ns). The available Offset range is –500 to +500 ms.

ASCII Time Code In/Out [1204-02, -04]

The ASCII Time Code Option Card, Model 1204-02 (RS-232) provides:
one male DB-9 RS-232 input connector (J2),
and one female DB-9 RS-232 output connector (J1)
The ASCII Time Code Option Card, Model 1204-04 (RS-485) consists of one RS-
485 input, and one RS-485 output, integrated in a shared terminal block con-
nector.
The interfaces accept Asynchronous Serial signals including date and time inform-
ation. The input and output Data Formats are selected among predefined
formats.
ASCII input
The ASCII input provides a serial data interface between an ASCII time generator
(e.g., another SecureSync unit), serving as an input reference for Time and 1PPS
in order to synchronize SecureSync (in conjunction with, or in lieu of, other avail-
able inputs, such as GNSS and/or IRIG).
ASCII output
The ASCII output provides SecureSync with the ability to output one, two or
three back-to-back ASCII time code data streams that can be provided to peri-
pheral devices which accept an ASCII RS-232 input data stream for either their
SecureSync 2400 User Manual
allows a Local Clock to apply a time offset for Time Zone and DST cor-
rection.
