6. Measurement Device Setup and Connection
6-4
To a wireless slave unit of command-response communications (CompoWay/F)(WZ-SRS01),
an RS-485-connected measurement device is connected. In such a case, a combination of its
group ID, wireless unit ID, and the unit number of the RS-485-connected measurement device
(CompoWay/F) is its identifier.
When the setting of wireless device unit is finished, make sure to connect a computer and the
wireless unit master and use the setup software WZ Manager (included in accessory CD-ROM
of WZ-MLAN01) for check the connection before connecting EQ100 and the wireless unit
master. This should make problem isolation easier between the wireless device unit and EQ100
when a problem occurs.
Precautions for
Correct Use
- Before using a wireless device, perform a wireless connection test at the site to install to
check normal communications.
