6. Gateway LED indicators
7. Connectors for external antenna: LTE x2, Mesh and Wi-Fi (future use)
Important note: Only the two connectors listed in bold above are usable, the
remainder relate to potential future functionality and are not currently supported.
Normally, no user access is needed to the gateway internals, all user connections
are made available externally at these interfaces.
1.3.2 LED indicators
The upper front panel of the gateway has positions for two, multi-colour, LED status
indicators – item 6 figure 2 above:
• Top, Power LED – furthest from the connector area:
o Green: gateway is powered
o Off: gateway is unpowered
• Lower, Status LED indicator
o Off: gateway is unpowered
o White: gateway is starting up
o Yellow: started but not yet connected
o Green: gateway has started and is also connected
Connected relates to the establishment of a connection between the gateway and the
@ptitude Observer MQTT service.
1.3.3 Data and event time stamping
Each gateway has a backup power capacitor which will maintain the Real Time Clock
(RTC) setting for approximately one week if the device is disconnected from power.
1.3.4 Data acquisition scheduling
The gateway is configured with four data acquisition schedules by way of Interval
and Interval alarm settings for both the Scheduled Trend Storage and Scheduled
Dynamic Data Storage. These schedules are common to sensors associated with a
machine and are set in @ptitude Observer at the Machine Properties level, Enlight
Collect IMx-1 System tab, see 2.4.1.
Notes on scheduling and measurements:
To ensure sensor network stability, the gateway is a master to the multiple sensor
‘slaves’ so a sensor can never initiate a measurement nor the transfer of data to the
gateway. Measurement and measurement data transfer is always at the request of
the gateway and these requests are sent sequentially to the different sensors.
