3.9.1.5 UTC Time and Date
The UTC (Coordinated Universal Time) date and time. This parameter is only configurable if the GPS Type is set to None.
Otherwise, it is the read-only data received from the GPS receiver.
The format is hh: mm: ss,dd/mm/yyyy, where hh is hours (between 0 and 23), mm is minutes (between 0 and 59), ss is
seconds (between 0 and 59), dd/mm is day/month, per usual date and month rules and yyyy is the year.
3.9.1.6 Clock Mode (GPS Chaining)
This parameter is related to the GPS Chaining functionality introduced in R5.0.
For a cluster of Compacts on the same site, GPS chaining enables you to connect one Compact to the GPS receiver (Master
unit). All other Compacts obtain clock feeds from the Master (Slave units).
The Master should be configured for the BreezeCOMPACT unit that is directly connected to GPS (either Standalone or
Chaining mode).
During installation, the operator must know which Compact is connected to the GPS in order to configure it as a Master. For
Slave units, the GPS In cable is connected from the previous Compact in the chain, and is configured as a Slave.
The maximum of 3 chain units is supported.
The following figure describes the connectivity for GPS Chaining mode.

3.9.1.7 Hold Over Passed Timeout
This parameter applies only when the External 1PPS is enabled. This parameter defines the period, in minutes, for which the
device provides holdover using its internal 1PPS clock after the loss of the external 1PPS signal. This parameter is not
relevant if the Stop TX After Hold Over Timeout (see below) is disabled.
The range is from 0 to 120 minutes. The default is 120 minutes.
