Enclosure - which houses all the above
components mounted, pre-wired and pre-
programed in a robust IP65 enclosure for
mounting on a suitable location such as a wall or
support frame.
SmartMux (Analogue / Digital): A smart
relay mechanism controlled by the
CPU to switch between multiple sensors so
that they can be monitored by a single
CPU. Allows multi sensors to be fed into the
measurement & control module.
Power Supplies: A power supply provides
regulated power to the logger and sensors.
12 volt DC fed either by 220 volt mains
adaptor and charger with 12 Volt DC battery
back up, 12 Volt DC battery with solar panel.
Communication: Remote or local
connection to the CPU to program or
download data including GSM, GPRS, radio
and cable.
Barometer - for compensation due to
changes in barometric pressure for sensors
used for pressure monitoring. (Not shown).

SmartMux ID Setup
SmartMux IDs are determined by the use of mini dipswitches at the front of each unit. These are usually preconfigured before you receive
them, according to your system design.
[1] Not used - always have DOWN
[2] 120Ω Termination Resistor - only have UP
when at the end of the string
[1] RS232/RS485 Switch - DOWN for RS485
[2] Not for customer use - always have DOWN
The setup is based on zero index binary, with the least
significate bit at the front.
Examples:
1 in binary is 00000001; on the mux it will be 10000000
15 in binary is 00001111; on the mux it will be 11110000
WHY back to front?!
9
A SmartMux will memorise the name of the first G8 it
communicates with and will only communicate with
that G8 from then on. If the G8 ID is changed, the mux
will not communicate with it.
A sign that this is happening is that the data file states
“NO-RX” where there should be data. In addition to
this, the red light on the SmartMux will not flash, only
the green light will come on (the SmartMux will take a
reading but it will not send it to the G8)
Rebooting a SmartMux
Reboot Mode
Rebooting the SmartMux will cause it to lose it’s memory and it will then be
able to communicate with a new G8
1. In the middle block of dipswitches, push all 1-8 up
2. Supply power to the mux. The easiest way to do this is by creating a local
reading of that mux (any channel)
The red and green LED lights on the front of the mux will flash alternately
3. After the lights begin to flash, press ESC repeatedly until the flashing stops
4. Rename your SmartMux by changing the dipswitches back to their original
configuration
5. Take a local reading from the SmartMux to confirm that you get a response

Incorporating a Digital SmartMux (DMUX) with Analogue SmartMuxs (GMUX)
NOTE
Digital & analogue SmartMuxs can
be connected together within a
chain
The digital SmartMux MUST BE at
the end of the RS485 line
The digital SmartMux only has one
ID per channel so you can either
connect one digital sensor (or string
of digital sensors) or an analogue
SmartMux into each channel
