SkyVUE Pro Ethernet Option

Summary
This document describes the configuration of a MOXA 5230A-T Ethernet adapter which has been
pre-installed in a SkyVUE Pro ceilometer. It should be read in combination with the User Guides for
the SkyVUE Pro and MOXA NPort 5000 Ethernet converter.
The Ethernet adaptor is setup as a TCP terminal server, which allows connection to the sensor over
an Ethernet connection, using software such as Campbell Scientific’s Viewpoint software. Any
commands that are described in the SkyVUE Pro that can be sent via the serial output can be sent via
the IP socket.
The SkyVUE Pro serial output can be converted back to standard serial (RS232/RS485) use by moving
cables inside the sensor as described below. When converted back the standard communications
cable at the base of sensor can be used as described in the SkyVUE Pro manual.

The hardware is shown in the internal view above. The Ethernet module is installed within the
SkyVUE Pro. It has serial connection (RS485) from the SkyVUE Pro and obtains power from it.
A special cable gland is fitted in the base of the SkyVUE Pro to allow a standard Ethernet cable,
pre-fitted with an RJ45 connector to be routed into the enclosure and plugged into the Ethernet
adaptor fitted inside the enclosure.
Note: RJ45 connectors which have large over mouldings may not fit through the gland.
The Ethernet cable should be
passed through the cable gland as
shown. Note that it may be
necessary to increase the diameter
of the cable, for example with heat
shrink sleeving or rubber sleeves,
to ensure a good seal around the
cable when the gland is tightened.
To convert the ceilometer back to
a standard serial connection swap
over the serial to MOXA cable
with the serial output cable as
shown.

Settings for SkyVUE Pro and Ethernet convertor as shipped
1) As supplied the SkyVUE Pro is connected for Ethernet use. It is setup for connection to the Ethernet
convertor using RS485 half-duplex mode, other settings are defaults. RS485 mode is used to allow
parallel connection of a local serially connected PC or datalogger, contact Campbell Scientific for
more information of these options.
2) The Moxa convertor as supplied is set to operate in “TCP” terminal server mode. The Moxa Interface
is set to communicate via serial port 1, using RS-485 2-wire mode. Other settings, which are the
defaults match the SkyVUE Pro defaults settings, e.g. baud rate etc.
3) The Moxa Ethernet port is set to its default static IP address of 192.168.127.254 with the SkyVUE Pro
connected to serial port 1 which is mapped to TCP port 4001 at that IP address.
4) The user will usually need to change the settings to suit their network. It may be necessary to change
the Ethernet mask and enter a gateway too (check with local IT support). It is also possible to
configure the Moxa to allow multiple remote connections to be made to the same sensor.
5) To change these settings, connect a PC to the Ethernet socket on the Moxa convertor and
communicate with it using a web browser using the address: http://192.168.127.254. The PC will
need to be configured so its IP settings allows it to connect to the 192.168.127.254 as a local
address. Once connected a web based menu system will be presented which allows you to change
the IP address of the box and setup security settings to prevent further unauthorised changes. If you
are not familiar with the setup of terminal servers please refer to the Moxa User manual, which can
be downloaded from here:

The model supplied is normally the 5230A-T. This has a second serial port which can be used to
connect other sensors or a datalogger to the same Ethernet connection.
Note: The SkyVUE Pro can be configured for message type, message interval and other parameters
using the USB port without disturbing any communications settings.
