Connecting Computer to Flow Meter
The 5000 Series can establish communication with a computer over
either a direct USB link utilizing a NDIS driver or over RS232 using a
USB to RS232 converter.
Direct USB NDIS Interface
Using the direct link USB interface is the preferred method to
establish communication. This interface is fast and only requires a
single USB cable between the meter and the computer. The same
cable will both power and transfer data. This connection will utilize a
standard USB driver called the NDIS driver.
For this connection to function, the NDIS driver needs to be loaded
onto the computer. This can be easily accomplished by installing the
free TSI Basic flow software package called FLO-Sight™. As part of
the installation, the install package will place the NDIS driver on the
computer. Refer to the main instrument manual for details on how to
install free TSI FLO-Sight™ software.
Steps to Establish Communication over NDIS
The first step of
establishing
communication is to have
an NDIS driver loaded on
the computer as described
above. Next, plug the
GP Flow instrument into
the computer using a
USB C to A cable and
allow it to boot. The
USB C connection is on
the flow meter side and
the USB A connection is
on the computer side. The
driver will automatically
load or you may need to
press accept on a dialog
that states a new NDIS
device has been found.

The driver function can be confirmed by looking into the computer’s
Next, enter the IP
address into the
terminal’s connection
dialog. Set the connection
to TCP/IP and enter the
port number of 3607. This
is shown in the
HyperTerminal®
Connection dialog.
Press
IP Address
device manager. The instrument will show up as a Remote NDIS
device under Network Adapters (see screen capture below).
The next step to test the communication is to open up a terminal
program and establish a TCP/IP winsock connection. The example
below is using HyperTerminal® Terminal program.
First, determine the device’s IP address using the instrument screen
by pressing the info tag. Each GP Flow insturment will have an
unique IP address.
Chapter 2
5
Now, commands typed into the terminal will be relayed to the
instrument and responses presented in the terminal screen. If the
connection is working, the meter will respond to a question mark
command “?” with “OK”.

The graphic below shows the full system for connecting the
instrument to the computer over NDIS.

RS232 Communication Utilizing a USB A to RS232
I n f o r m a t i o n
The 5000 Series instrument must be rebooted after
attaching the USB to RS232 adapter.
I n f o r m a t i o n
The serial cable between the GP Flow instrument and
the computer must be a null modem cable.
Adapter
Another method for communicating to the GP Flow instrument is to
utilize a USB to RS232 adapter and then communicate to the
computer using RS232 protocols.
The first step is to connect a USB to RS232 converter to the GP Flow
instrument. The converter must be based on the FTD based drivers
for it to function with the GP Flow instrument. TSI sells a converter
tested to work with the instrument P/N 5000-RS232. After attaching
the converter, the GP Flow instrument must be rebooted. See
graphic below.
Once the meter has been rebooted, a DB9 Null modem serial cable
can be attached to the computer.

instrument and the computer, that connection can be tested using a
Terminal program.
Now, commands typed into the terminal will be relayed to the
instrument and responses presented in the terminal screen. If the
connection is working, the meter will respond to a question mark
command “?” with “OK”.

Note that the RS232 baud rate is factory set at 115,200. This rate can
be changed to 38,400 to be backwards compatible with the 4000
Series instrument. See the baud rate commands in the manual for
steps in changing the baud rate.

ASCII Protocol
Command Format
The serial interface commands in this manual are designated by the
bold font (ex. DmFTPnnnn). The commands are case-sensitive.
Upper case letters are used throughout the command set except as
designated.
The TSI Series 5XXX use ASCII characters as the input command
set. Each command sent to the flow meter must be terminated by a
carriage return (CR = 0x0d). Line feeds (LF = 0x0a) are ignored.
Select commands allow you to choose either ASCII or binary format
for the returned data. Binary data transfers allow for faster operation.
The TSI Series 5XXX flow meters send an acknowledge sequence to
confirm that the command was received. For ASCII commands, the
acknowledge sequence is “OK” <CR><LF>. For binary commands, a
single byte, 0x00, is returned.
The ASCII command set for the Series 4000 / 4100 flow meters
(4000-4100-RS-Command-Set P/N 1980340) is backwards
compatible with the TSI Series 5XXX flow meters. This manual lists
which commands also work with the Series 4000 / 4100 flow meters
and also include additional commands specifically for the additional
functions of the 5XXX series.

D
Denotes data transfer.
m
Denotes data format: A = ASCII, B = binary,
C = ASCII followed by CR and LF.
F
Requests a flow reading (replace with lower case “x” if a
flow reading is not desired).
T
Requests a temperature reading (replace with a lower case
“x” if a temperature reading is not desired).
P
Requests a pressure reading (replace with a lower case “x”
if a pressure reading is not required).
nnnn
Denotes maximum number of samples to return, range is
1 to 1000. (“0500” denotes 500 readings, leading zeroes
must be included).
DmFTPnnnn
Backwards compatible with Series 4000 / 4100 flow meters.
Returns Flow, Temperature, and Pressure data at an interval equal to
the sample rate.
The data is returned in the order of Flow, Temperature, and Pressure.
All three measurements may be requested or a combination of the
three as indicated below.
Example 1) DAFxP0250
Requests 250 readings of flow and pressure data in ASCII format.
Example 2) DBxTx1000
Requests 1000 readings of temperature in binary format.
Flow data is returned in units of Std. L/min or L/min (see SUn
command).
Temperature data is returned in units of °C.
Pressure data is returned in units of kPa.
Before initiating this command, the sample interval, gas calibration,
and flow units should be set.
The sample interval between data points is set using the SSRnnnn
command.
The gas calibration is set using the SGn command.
The units of standard or volumetric flow is set using the SUn
command.
16 Chapter 4
The data can be returned in either ASCII or binary.
If ASCII mode is chosen, the acknowledge sequence is “OK”
<CR><LF>. If the command generated an error, an error code
“ERRn” <CR><LF> will be returned where n represents an error code
0 through 9. See Appendix A for a list of possible error codes. The
readings returned are separated by commas and the termination
sequence is a <CR><LF>. The Series 4000 / 5300 sends two decimal
places, and the Series 4100 / 5200 sends three decimal places for
flow rate.
If binary mode is chosen, a single byte, 0x00, will be returned as a
command acknowledgment. If a command generated an error, a
single byte will be returned in place of the acknowledgment byte. See
Appendix A for a list of error codes. Each reading returns two bytes.
The most significant byte is returned first. Flow rate data is returned
as an unsigned integer (0 to 65535) that has been multiplied by 100
(for Series 4000) or by 1000 (Series 4100). Temperature data is
returned as a signed integer (-32768 to 32767) that has been
multiplied by 100. Pressure data is returned as an unsigned integer
that has been multiplied by 100. To convert the returned data back to
its original form, divide the data by 100. Binary transfers terminate by
returning two bytes in the form 0xff. Check the first reading in each
block of data returned (flow, temperature, and pressure) from the unit,
for the terminating sequence. No termination sequence will be sent if
an error condition occurred.
Special note: A temperature reading of –0.01C would be
transmitted as 0xff and could signal an early
termination if flow readings were disabled.
If no begin-trigger is set, the data acquisition begins immediately
upon processing of the command. If a begin-trigger is set (set with
SBTxnnn.nn), the data acquisition begins as soon as the begin-
trigger condition is detected. If no end-trigger is set, then nnnn
samples will be used in the data set. If an end-trigger is set (set with
SETxnnn.nn), then the acquisition will stop either when the end-
trigger condition is detected or when nnnn samples have been
acquired; whichever comes first. After the command is finished, a
termination sequence is sent to signal the end of the transfer.
Example 3) SSR0010
Set sample rate to one average sample every 10 ms.
Flow meter returns OK <CR><LF>
Command Set 17
SG1 Use the oxygen gas calibration.
Flow meter returns OK <CR><LF>
SBTF+001.00
Begin sample by triggering on increasing flow at 1.0 Std. L/min.
Flow meter returns OK <CR><LF>
DAFxx0005 Request 5 samples of flow in ASCII format.
Flow meter returns OK <CR><LF>
Flow meter returns flow data as follows.
1.10,1.20,1.25,1.23,1.20<CR><LF>
Example 4) DBFxx0005
Request 5 samples of flow in binary format.
An example of the data that could be returned is as follows.
0x00 0x33 0x09 0x33 0x1f 0x33 0x25 0x33 0x2d 0x33 0x2e 0xff 0xff
After conversion, the data would look like:
130.65 130.87 130.93 131.01 131.02
Example 5) DCFTx0005
Request five samples of flow and temperature in ASCII format but
with <CR> and <LF> following each data set.
Returns data as follows.
1.10,23.45<CR><LF>
1.20,23.53<CR><LF>
1.25,23.48<CR><LF>
1.23,23.39<CR><LF>

Requests a Humidity reading (replace with lower case “x” if
a flow reading is not desired).
L
Requests a low pressure reading (replace with a lower case
“x” if a temperature reading is not desired).
I
Requests a totalizer reading (replace with a lower case “x”
if a pressure reading is not required).
nnnn
Denotes maximum number of samples to return, range is 1
to 1000. (“0500” denotes 500 readings, leading zeroes must
be included).
Returns Flow, Temperature, Absolute Pressure, Humidity, Low
Pressure, and Totalizer data at an interval equal to the sample rate.
The data is returned in the order of Flow, Temperature, Absolute
Pressure, Humidity, Low Pressure, and Totalizer. All six
measurements may be requested or a combination of the three as
indicated below.
This command follows all the same rules documented in the
DmFTPnnnn command.
This command has the special case where setting the nnnn to 0000
will result in 30 seconds of streaming data. The total number of data
points will be dependent on sample rate. For example, it the sample
rate is 10 msec, then this command will stream out 300 readings over
30 seconds.
Command Set 19
Vmnnnn
V
Denotes volume measurement
m
Denotes data format: A = ASCII, B = binary
nnnn
Denotes maximum number of flow samples to integrate,
range is 1 to 9999
(“0500” denotes 500 readings, leading zeroes must be
included)
Backwards compatible with Series 4000 / 4100 flow meters.
Returns a volume measurement by integrating flow rate over time.
Example 1) VA2000
Request a single volume reading by integrating a maximum of 2000
flow samples and return data in ASCII format.
Volume data is returned in units of standard liters or volumetric liters
(see SUn command).
Before initiating this command, the sample interval, gas calibration,
and volume units should be set.
The sample interval between data points is set using the SSRnnnn
command.
The gas calibration is set using the SGn command.
The units of standard or volumetric is set using the SUn command.
The most common units are volumetric liters.
The data can be returned in either ASCII or binary.
If ASCII mode is chosen, the acknowledge sequence is “OK”
<CR><LF>. If the command generated an error, instead of “OK”
<CR><LF> being returned an error code “ERRn” <CR><LF> will be
returned where n represents an error code 0 through 9. See
Appendix A for a list of possible error codes. The termination
sequence is a <CR><LF>.
If binary mode is chosen, the acknowledge sequence is a single byte
0x00.
If the command generated an error, a single byte error code will be
returned instead of 0x00. See Appendix A for a list of possible error
codes. The reading is represented by 2 bytes. The most significant
byte is returned first. The data is represented as an unsigned integer
20 Chapter 4
(0 to 65535) that has been multiplied by 100 (Series 4000) or by
1,000 (Series 4100). Therefore, you must divide the integer that is
returned by 100 or 1000 to get the correct result. The termination
sequence for binary is 0xff 0xff.
If no begin-trigger is set, the data acquisition begins immediately
upon processing of the command. If a begin-trigger is set (set with
SBTxnnn.nn), the data acquisition begins as soon as the begintrigger condition is detected. If no end-trigger is set, then nnnn
samples will be used in the integral. If an end-trigger is set (set with
SETxnnn.nn), the acquisition will stop either when the end-trigger
condition is detected or when nnnn samples has been acquired;
whichever comes first. After the command is finished, a termination
sequence is sent to signal the end of the transfer.
Example 2) VA1000
Request volume measurement with at most 1000 samples, data
returned in ASCII.
Returns volume data as follows: OK <CR><LF> 130.651 <CR><LF>
Example 3) VB1000
Request volume measurement with at most 1000 samples, data
returned in binary.
Returns data as follows: 0x00 0x33 0x09 0xff 0xff
After conversion, the data would look like: 130.65

After the command is processed, an acknowledge sequence of “OK”
<CR><LF> is sent. If the command generated an error, instead of
“OK” <CR><LF> being sent an error code of “ERRn” <CR><LF> will
be sent. See Appendix A for a list of possible error codes.
SUn
Select either standard or volumetric units of flow for data displayed on
the LCD display and for data received through the serial port.
This will control the units of measure for the gas reading over the
communications port. To change the units of measure shown on the
GUI screen, use the instrument’s touch screen (reference the user
manual).
The Series 53XX and 52XX flow meters are designed to measure
flow in units of standard L/min. When selecting volumetric flow rate,
they perform a flow correction as shown below by measuring gas
temperature and pressure. Flow output in volumetric L/min is less
accurate due to additional uncertainties encountered when measuring
gas temperature and pressure.

Under NDIS mode does the meter
always use the Link Local IP
space (169.254.x.x/16) or will it
allow the user to set a static IP?
The meter always uses the LinkLocal IP address space. It does not
allow you to set a static IP.
Can the meter set its IP from a
DHCP server?
No, the meter does not get its IP
address from a DHCP server.
When using NDIS and the Link
Local address space is the IP
address guaranteed to the same
between meter and system
reboots.
Yes, the meter will always selfassign the same Link-Local IP
address.
