and read the System Time. Local timescale allows a Local Clock to apply a
time offset for Time Zone and DST correction.
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 cre-
ated 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 information on Local
Clocks.
Offset: Provides the ability to account for HAVE QUICK cable delays or other laten-
cies in the HAVE QUICK outputs. The Offset values are entered in nanoseconds
(ns). The available Offset range is –500 to +500 ms.
2.20.7 Configuring an IRIG Output
IRIG DCLSOutput is available through the Multi I/O connector in the default settings
(pins 6 & 7), and can also be configured on the DCLS OUT BNC connector on the front
panel, as well as through the mutli I/O connector on either of the two RS485 channels
(pins 3, 13, and 8, and pins 4, 14, and 9). See "Configurable Connectors" on page136 for
more information. None of these listed channels allow IRIG AM outputs.
IRIG AM Output is available in the default configuration through the IRIG AM Output chan-
nel (pins 11 & 12) o(n the Multi I/O connector Additional outputs of IRIGAM would require
an option card..
In the default configuration:
IRIG Output 0 represents IRIG DCLS output (pins 6 & 7). This channel can only be
DCLS.
IRIG Output 1 represents the IRIG AM output (pins 11 & 12). This setting can only be
configured to AM.
The numbering of outputs and inputs can change during pin layout changes (and when
option cards are added).
Possible settings will be limited by the interface you are configuring.
To configure the settings of one of the two IRIG Outputs, go to its Edit window. For
instructions, see: "Configuring Option Card Inputs/Outputs" on page336.
Note: The choices available will change based on the type of IRIGyou have
chosen to configure.
