Introduction
The Quad MF isoPod (model number EPU452) is a four–channel, miniature amplifier/interface that connects to a Windows XP or later computer via a USB port or hub. Each of its four channels (Ch 1, Ch 2, Ch 3, and Ch 4, Figure 1) can be independently configured to one of seven possible functions:
- mV, a general purpose high impedance millivolt monitor;
- pH, a pH meter mode. Also suitable for ion selective electrodes (ISE's) and oxidation/reduction potentiometric (ORP) electrodes.
- Conductivity, for two-electrode solution conductivity probes.
- RTD, precalibrated for 1000 ohm platinum RTD temperature probes
- Thermistor, precalibrated for 30 kohm thermistor temperature probes
- dO2, for Clark–style polarographic oxygen electrodes.
- Biosensor, for amperometric sensors, incuding enzymic peroxide sensors.
This manual also describes the operation of:
- • the MF Configurator software, used to set up the system, and
- • the embedded serial protocol, which is required if you intend to write your own data acquisition and display software, or interact manually with the isoPod by issuing typed commands using terminal emulation software.
Please see the separate Pod-Vu software manual to learn about collecting and displaying signals without any additional programming!
Checking the Instrument
Before you begin working with the device, you should check:
- • that the contents of the package you received match the packing list
- • for any sign of physical damage that might have occurred during transit.
If you find a problem, please contact your eDAQ distributor or agent immediately.
Quick installation
- Install the MF Configurator and Pod-Vu application software on your computer using the USB memory stick provided. This will also ensure the correct software drivers are installed.
- See the Help menu of the application for directions to any software updates.
- Power the MF isoPod by connecting it to the 5 V DC mains adaptor supplied.
- Connect the MF isoPod unit to the computer using the USB cable provided.
- For first use, run the MF Configurator software to select the function and set the parameters of each channel.
- Attach appropriate sensor probes to each of the isoPod channels.
- You can now run the Pod-Vu software to collect and display data, or start writing your own data recording software.
CAUTION: Make sure that only a compatible sensor is attached to each channel.
Placement of the wrong sensor on a channel (eg connecting a pH electrode to a dO2 recording channel) may damage the probe. Both the MF Configurator software utility and Pod-Vu recording software will display the device configuration.
System Description
This system consists of four independently isolated, reconfigurable, signal conditioning and measuring circuits connected to a microprocessor which communicates with a Windows XP or later computer via a USB port Figure 2. Sensors are connected using the front panel low–leakage BNC input connectors. The signal on each channel is converted to a digital data stream by a precision 24 bit analog to digital converter (ADC). The data is passed to a master microprocessor across an electrical isolation barrier for processing and transmission via a USB port to the computer for display and storage. Each of the four channels input can be independently configured as:
- • Voltmeter (mV)
- • pH/mV and Ion Selective Electrode (ISE) meter
- • Solution Conductivity meter
- • RTD Temperature meter (0 – 450°C)
- • Thermistor Temperature meter (0 – 75, or 0 – 125°C)
- • Dissolved Oxygen meter (dO2)
- • Biosensor meter (for amperometric/polargraphic probes)
by use of the MF Configurator software (included).
Operating Software
The system is provided with two support applications:
- • Pod-Vu software which enables Windows computers to calibrate, collect, and display signals. Up to eight isoPods channels (i.e. two Quad MF isoPod units can be connected simultaneously for monitoring eight probes) can be graphically displayed at speeds up to 1 sample per second. Data can be copied and pasted to other software applications for further analysis or reporting, or saved in text format which can be read by spreadsheet or word processor software. Channels need to be configured to suit user requirements using the MF Configurator prior to use with Pod-Vu. The operation of Pod-Vu is described in the separate Pod-Vu manual.
- • MF Configurator software utility is provided with the system and enables channel functions to be configured and sensors tested and calibrated. This utility must be installed prior to using the Quad MF isoPod. Once the channels are configured the isoPod will remember the settings and perform in this mode every time the system is subsequently powered up, until the system is reset by using the MF Configurator.

Unit Set-Up Screen The unit setup screen allows three important actions to be performed:
- • Assign a function, from those available, to each Channel
- • Select the range, decimal places and calibration for each channel function.
- • Display sensor data for checking and calibration purposes.
Paul D– should we add a description of each different range/calibration panel? No but you do need one for each function (pH, conductivity etc) (PD)
Serial Protocol
This serial protocol is stored within the isoPod unit and can be used with any suitable terminal emulation software (for example Tera Term) to communicate with the EPU452. With a terminal program installed and set up correctly with the EPU452 connected via the USB port to the PC, the system will respond to a set of commands described in here.
Establishing serial communications
With the ER452 connected and powered up communication with the computer can be established. A suitable terminal emulation software application must be installed. Serial Ports 1 and 2 on Windows computers are reserved for the mother board. It is therefore common to find that the EPU452 or other serial devices are assigned automatically to serial port 3 (COM3) or greater. Use your Terminal software to configure the virtual serial port as shown below (based on the use of Tera Term). Serial port item is then selected from the Tera Term Settings menu item in order to setup the serial port.
Select COM port to which the ER452 is connected.
The virtual serial port should then be configured as:
- • 115200 baud
- • 8 bits
- • 1 stop bit
- • parity set to none
- • Flow control set to NONE
Commands
Once the serial port is set up, type in a ? to get a listing of the available commands listed in Appendix X. An ‘enter’ will produce an ER452> prompt requesting one of the protocol commands.
This protocol can also be used by other applications such as:
- • LabVIEW™
- • WinWedge®
- • Tera Term or
- • with your own software written in Visual Basic, or C++, etc.

Advanced settings commands
A number of advanced commands are available to users providing their own operating software. Contact eDAQ for support.
Sampling rates
The s sample command will show readings at 1Hz (the default), or a rate that you can optionally specify.
There are a limited number of sampling rates available (get rates lists available rates for a specific function. The valid rates available may depend on what functions and ranges are assigned to the channel. Conductivity is special case, in that sampling rates also depend on the range being used. Sampling can only occur at a speed common to all channels. Maximum sampling rate is 100s/Sec.
If multiple functions are active, then only the lowest common sample rate that all the channels "agree upon" will be used. In the example below, if conductivity channel is chosen to operate at 10 samples per second, then the mV channel will also operate at 10 /s.
An example showing the different rates available for mV compared to mid-range conductivity:
