4 ASCII Data Stream via USB
ASCII Flow Data Stream via USB for Pulsite®Link, is a feature to ease customer system
integration.
Each meter operates whilst real-time flow readings are streamed as ASCII encoded Carriage-
Return + Line-feed terminated strings, via the USB connector. Thus, enabling easy integration
of the Pulsite® Link flow information into customer operating and monitoring systems. Each
ASCII line is a single number with decimal point, showing the flow rate in the configured units
and time period, (e.g. litres per minute). Scientific format is not used and the output is restricted
to six decimal places.
The flow readings are reported at approximately 10Hz and configured as the same as those
set in the meter using the “Titan Interface Software”.
4.1 How to Enable ASCII Streaming
ASCII streaming is conveyed via the FTDI USB chip (FT232RL) and requires the FTDI driver
to be loaded on the PC being used. Windows drivers are loaded automatically with the
installation of the Titan Interface Software.
More details on the FTDI USB communications can be found at https://ftdichip.com/
On power up, the unit defaults to ASCII Streaming mode of flow data. This is an “output only”
and any message received by the meter will automatically switch the communication mode to
“non-streaming”. For example, when the Titan Interface Software attempts connection it will
first switch the unit into “non-streaming” mode. On exiting, the software will automatically return
the connected meter into ASCII streaming mode.
NOTE: If the Titan Interface Software is not closed correctly or the meter is disconnected via
the cable prior to closing the software, the ASCII will not be enabled.
4.2 Serial Port settings for ASCII Streaming
Windows™
The Virtual COM port (VCP) driver must first be enabled for the USB Connection.
See Appendices for details on how to do this.
Linux™
The VCP driver is enabled by default.
After the serial port driver has been enabled, customer software should configure the COM
port with the following settings:
•FTDI Baud Rate*: 1000000
•Parity: None
•Stop Bits: 1
•Data Bits: 8
*NOTE: The ASCII streaming is not RS232 like data transmission. The Baud rate must be set
to the indicated value to enable the Pulsite®Link to communicate via USB. The FTDI VCP
driver converts the USB data stream to ASCII.
A test program for Windows™, (ASCII_Test_Pulsite®_Link.exe), is included which can be used
to verify that the Pulsite®Link stream is being properly received by the PC. Also included is a
Python Script for testing on Linux™systems.

5 Interface Setup
5.1 Connecting Meter to PC
Before use, download and install the Titan Interface Software from memory stick or the
Website.
The Pulsite®Link should be set up using the USB interface and a suitable windows-based
computer.
Below is a screen shot of the opening Software screen:
NOTE: When correctly connected the bars will rotate in the bottom left hand corner
and you should see “All Controls enabled”
On connecting the Pulsite®Link, after 5-10 seconds,the Software will normally
automatically load the settings saved in the non-volatile memory of the connected
meter. The user can use the spy-glass icon to automatically pull the meter’s saved
settings at any time.
This software allows the user to configure all options of the meter. Detailed descriptions follow,
but if the user hovers the mouse over a menu item, a brief description will be displayed to help.

5.1.2 Retrieve Settings from Meter
When connected the settings will normally be automatically retrieved from the meter.
If this is not the case, or the user wishes to check the meter’s saved settings against those
shown in the software, they can be retrieved from the non-volatile memory of the flow meter
by pressing the spy-glass icon.
On the User Settings Tab, when the software information and the instrument information do
not match, there is a message line which will present “Settings do not match meter” or “Settings
Match Meter RAM”, whereby the unit has not permanently saved any differences to the meter.
The software message bar will display “Settings match meter non-volatile memory” once any
changes are saved:
5.1.3 Save Settings to Meter
As configuration adjustments are made in the software the operation of the connected
meter will change accordingly but will not store those setting changes until the Save Settings
icon is pressed.
This is indicated in the message bar in the User Settings by “Settings match meter RAM” text:
To save new settings to the non-volatile memory click the and the Confirm save menu
will appear before those settings are stored.
Clicking Undo changes reverts all the settings to those in the Non-volatile memory.

Once stored, the software message bar will display “Settings match meter non-volatile
memory”:
5.1.4Test Outputs
This tab enables the user to manually set
outputs on the outputs for testing to the
target device.
Once the required output is selected,
click the “Start Test” button and all PINs
will give the selected output rate for 32
seconds.
5.1.5 Software Information

5.3 Pulse Input Tab
5.3.1 Pulse Input Configuration
Reed Relay: Use when connecting a Reed relay flow
meter.
When ticked, this provides an additional extended filter in
which a logic high signal must be high for at least 560μs
before it is propagated; whereas a logic zero is propagated
immediately. This is intended for a circuit in which the reed
relay switches to ground with a pull-up resistor.
Detection: Pulse detection can be chosen for Rising edge,
Falling edge or Both edges of the input pulse.
“Both edge” detection measures both the rising and falling
edges.

®
Output Smoothing: This selects the rate that the analog
output and asynchronous pulse outputs are updated.
Chose Automatic and the Pulsite Link will adjust the
sampling response time to the fastest available from the Hz
pulse input.
Alternatively, the user can chose a single response time for
the flow range of operation. For continual reliable sampling
the slowest response time must be slower than the lowest
expected input rate.
Once the calibration data is entered the smoothing cutoff
will display the lowest flow that can be reliably measured.
Hovering your mouse over the Cut Off value in the User
Settings tab will also show the Smoothing cut-off and
recommend you set above this value.
Setting the cut-off value below the recommended level
means that when the flow is between the set value and the
recommended value, the display will occasionally read
zero.
K Factor Values: Enter 1 to 10 sets of values of flow and
pulses per litre (K factor) as found in the calibration
certificate supplied with your flow meter or instrument
5.4 User Settings Tab
5.4.1 Calibration Settings
Units: A drop down menu offers the choice of Litres, ml, gms,
kg, US gallon, Imperial gallon or Custom units i.e. blank.
Note that the Custom Units setting will be equivalent to Litres if no
modifications are made to scale factor.

Rate (units per): This is the time base for the flow rate and
has the option of Second, Minute or Hour.
Scale Factor Adjustment: This allows the user to adjust or
tune the calibration flow value if required.
Density: The flowmeter is fundamentally a volumetric device,
but a density figure can be entered here if one of the mass
units is selected. Caution must be used however, as there is
no temperature/density correction.
Cut Off: Flow values below this level will be set to zero.
5.4.2 External Connections
Within this section the user can configure pulse, analog and alarm outputs.
