1Introduction
The Valeport miniIPS2 and 2e “Intelligent Pressure Sensor” builds on the success of the industry standard
miniIPS.
•The miniIPS2 operates over serial comms - RS232 and RS485.
•The miniIPS2e operates over Ethernet (TCP/IP).
Designed to measure water pressure and provide a real time output of that data in a number of formats
and units. The miniIPS2 and 2e are fitted with an Interchangeable, depth optimised, pressure sensor
allowing the most operationally suitable pressure sensor module to be fitted for the operational water
depth. To be used in a variety of subsea applications ROVs, construction survey, monitoring and
positioning operations, one of the key development drivers was to provide a cost effective alternative to
the use of resonant quartz pressure sensors. Using the very latest technology in temperature compensated
piezo-resistive transducers, the miniIPS2 and 2e offers several advantages over resonant quartz sensors,
with similar performance - cost, maintenance and operationally specific pressure ratings.
•Interchangeable pressure sensor module
-Pressure ranges from 10 to 600Bar (approx 100m to 6 000m water)
-Titanium diaphragm pressure sensor
▪No external diaphragms, oil reservoir or oil-filled tubes
-Long term calibration stability
-2 year recommended recalibration cycle
•Titanium housing
•RS232 or addressable RS485 data output
•ASCII and Modbus RTU output protocols
•Choice of calibrated data formats
•TEOS 10 seawater properties of water computation for depth calculation
•Choice of sampling modes

2.1 Pressure Sensor
The miniIPS2 and 2e are fitted with the following sensors:
•A high accuracy, 0.01% of full scale, temperature compensated piezo-resistive pressure transducer.
•The Pressure Module is interchangeable
Sensor Type
Strain Gauge
Range:
individual modules
10, 20, 30, 50, 100, 200, 300, 400 or 600 Bar
1 bar is approximately equal to 10m depth
Resolution:
0.001% of full range
Accuracy:
±0.01% or full range
Response Time:
1 millisecond
2.2 Interchangeable Pressure Sensor Modules
The Interchangeable Pressure Sensor Modules can be swapped to best suit the operational depth of the
project. The accuracy of the sensor is a factor of the full-scale capability of the sensor - 0.01% and not the
measured pressure. A 600 Bar module will offer the same ± 0.60m accuracy at 6000m as it will at 250m
while a correctly selected 30 Bar Pressure Module, for an operation at 250m, will provide an accuracy ±
0.03m

Prior to changing out a Pressure Module the mini IPS 2 or 2e should be thoroughly rinsed in fresh water and
dried.
A Pressure Module should ideally be changed in dry lab conditions but if this is not possible every effort
must be made to keep water out of the module socket. If water does get in, it must be dried before a
replacement module is fitted to protect the connector from corrosion.
A special tool is provided to unscrew the fitted module and screw its replacement securely into place.
Never use excessive force.

The three prongs should be carefully inserted into the lock screw cap of the Pressure Module and turned
counter-clockwise (when looking directly at the module) to loosen it. Keep turning until the Pressure
Module gently pops out of the socket. The tool will engage with the Pressure Module and allow you to very
gentle pull if required.
Before fitting a replacement Pressure Module check all surfaces for wear - especially the lock screw cap.
Check the O rings are clean and free of any debris, wear or damage. There is no need to grease the O rings.
The closing action of the system does not rely on surfaces sliding over one another and grease might attract
debris that would compromise the seal.
The replacement Pressure Module should be placed into the socket with the connector approximately lined
up with its pair. Fine adjustment is achieved by the shape of the module housing in the socket.
Engage the screw cap into the threads of the socket and then use the tool to tighten the Pressure Module
into place. The module should be screwed down until the shoulder of the lock screw cap is in line with the
shoulder of the titanium end-cap as shown below:
Do not over tighten.
Inside the transit case an additional transit case is provide for the Pressure Module to all it to be sent off for
calibration without the need to send the whole instrument.

4Communications
4.1 Introduction
Control of the miniIPS2 and 2e is achieved through the use of “# codes”, as described in the sections below.
All commands must be “sent” by pressing the Enter key
with the exception of the single ‘#’ character required to enter set up mode
4.2 Serial Comms - RS 232 and RS485
miniIPS2 is fitted with both RS232 and RS485 communications as standard. RS485 is enabled by grounding
a pin in the communications lead (refer to Wiring Section).
Protocol is 8 data bits, 1 stop bit, no parity, no flow control.
Baud rate is factory set to 115200. User may choose between 1200, 2400, 4800, 9600, 19200, 38400,
57600, 115200 and 230400.
Fast data rates and longer data string outputs may n\ot be possible with low baud rates

4.3 Ethernet
The miniIPS2e is fitted with a Transmission Control Protocol/Internet Protocol (TCP/IP) Ethernet module set
up in Dynamic Host Configuration Protocol (DHCP). This means the instrument will automatically be
assigned a IP address. Depending on how your router works, it should go back to that IP address each time
it is interfaced although this is not guaranteed unless you provide it with a fixed IP in the router
configuration.
4.3.1 Setting up Ethernet Connectivity
The miniIPS2e has a Lantronix Ethernet module that will need to be configured. You can download the
Lantronix Device Installer software from here.
Connect the miniIPS2e to the network and run the software. If the device is not found after a few
moments press Search, top left
Once the module has been found click on XPort to reveal the IP address - in the example above:
192.168.8.155
Click on the IP Address in the left hand panel to reveal more information in the right hand panel
Select Web Configuration
Select the green arrow to reveal the password entry dialogue
Do not enter a Username or Password - simply select OK
