How to Connect with Wireless Field
Equipment
Here we will describe the procedure to connect field
wireless devices to the GX20W (paperless recorder
wireless model).
Overview
To explain the connection procedure, we will use an
example of configuring a new system consisting of a
single GX20W (wireless gateway; hereafter referred to
as the built-in GW) and a single field wireless device
(YTMX580), as shown in figure 1.
Figure 2 shows the internal configuration of the GX20W.
The connection from the external Ethernet device
(configuration PC) passes via connector PORT1 and is
distributed to the recorder CPU and the built-in GW via
internal connector PORT2. The measurement data from
the wireless device is collected through Ethernet via the
built-in GW.
