3.5 Clock System

The software real time clock that controls the system records seconds, minutes, hours,

day, month, year and day of week. The clock also has a standby RTC circuit which

remains supported during power failures for up to 48 Hours.

An external RTC backup input on the CPU board (Modem Power Connector Pin 4 - Table

5) can be linked to the RTC output on the PSU board (General Functions Connector Pin 1

- Table 12) to provide extended RTC backup from the lead acid battery.

The clock can be synchronised to network time (NTP) over a suitable IP network. NTP

synchronisation is required for UG405 UTC operation.

3.6 Self-Test Facility

The Self-Test functionality is primarily intended for factory testing as many of the tests

require special loopback adaptors. The feature may prove useful when diagnosing certain

faults in the field. Self-Test checks as much of the hardware as possible and may be run

on demand from the Tester webpage. It is a completely separate function provided by the

firmware.

The self test facilities are described in detail in section 6.

3.7 Lamp Supply Monitoring

The Lamp supply monitor provides a means to check that the lamp supply voltage is dim

or bright and within specification. The two terminal input can accept either LV or ELV

voltages. Connect the lamp supply to the two pin Lamp Supply Monitor Connector on the

PSU Board (section 5.9).

Currently the lamp supply RMS voltage is available via the webpage real time view (see

below); however future software features will integrate this information with the instation

for monitoring.

Webpage - Status and Configuration – System – Status – Real Time View

then selecting Stratos – Lamp Supply Voltage.

3.8 User Interface

The primary interface for user actions is a web based interface available locally over the

USB handset port and WiFi (with suitable USB WiFi dongle) and on a network via the

Ethernet interface. This interface gives access to and control of all areas necessary for

day to day maintenance including:

 System Status and Configuration.

 System Log.

 Fault Table.
