1.2 System communications
The communications setup or mode, determines how the IMx-16Plus will
communicate with the wider system. There are 3 alternative arrangements that can
be used:
•
Server initiated (@Observer initiated communication)
•
Client-Server (the IMx-16Plus
is the initiator of the communication)
•
Standalone (no connection to @Observer)
Whilst the first two are alternatives for @Observer/IMx communication, illustrated
diagrammatically in
the Standalone option refers to operating the IMx-
16Plus independent of @Observer software and instead using the companion app, to
interact with the IMx. For standalone mode, refer also
Whilst the different network possibilities (
to
connection methods, there are limitations on the permissible combinations of
communication mode and network connection method:
1. Server initiated, requires a server installed on a local network (with RJ45 or
Wi-Fi connection).
2. Mobile data connectivity is only supported in Client-Server mode (device
initiated communications).
The choice between using a mobile data connection or a LAN connection (RJ45 or
Wi-Fi), is part of the IMx-16Plus configuration.
1.2.1 Mobile (LTE/GSM) data
A built-in module provides a mobile data connection (GPRS, LTE). It can work world-
wide and provides connectivity to @Observer software. Mobile data functionality
requires an activated SIM card or eSIM. An external antenna is required (
); two
LTE connectors are provided.
1.2.2 Local network RJ45 or Wi-Fi module
A built-in Wi-Fi module provides a Wi-Fi communication interface (2,4 GHz) so that,
where available, that can be used as the first stage of connectivity to @Observer
software, rather than a hard-wired LAN (RJ45) or the mobile (LTE/GSM) network.
Similarly to mobile data, an external antenna is required for Wi-Fi, the optional
antenna offered by SKF (
) fulfils both roles.
