Chapter 1
General Information
1.1 Introduction
This User’s Manual will:
!Explain the electrical and pneumatic pressure connections for the Model 9116 Intelligent
Pressure Scanner.
!Provide computer set-up instructions to make a proper Ethernet connection on most
Windows®95/98/XP/NT-based personal computers.
!Instruct you on using the PSI start-up software to manipulate and acquire data from each
module.
!Instruct you on how to program each module with computer software.
Model 9116 is a pneumatic Intelligent Pressure Scanner, with integral pressure transducers and
a pneumatic calibration manifold.
The Model 9116 provides engineering unit pressure data with guaranteed system accuracy.
This is achieved by reading factory-determined pressure and temperature engineering-unit data
conversion coefficients from its transducers’ nonvolatile memories at power-up. It also allows
additional adjustment coefficients to be “fine-tuned” with a multi-point calibration under host
control (e.g., possibly utilizing optional Pressure Systems 903x Pressure Calibrator modules).
Model 9116 provides an auto-configuring 10BaseT/100BaseT Ethernet communications port.
Half duplex/full duplex operation is also automatically configured. The Model 9116
communicates using the TCP/UDP/IP protocols.
The Model 9116 Intelligent Pressure Scanner is a component of a networked data acquisition
concept called the NetScanner™ System. Multiple NetScanner modules measuring a wide
variety of parameters can be networked to form a distributed intelligent data acquisition system.

Model 9116 Intelligent Pressure Scanner
1.2 Description of the Instrument
The Model 9116 is available with16 channels, each with individual pneumatic transducers per
channel. The most distinctive features are highlighted below:
●Pre-calibrated Transducer - a memory chip containing full calibration data is embedded
within each internal transducer.
●Individual transducer per measurement input channel - mixed transducer ranges may
be installed in a single Model 9116 module.
●Low cost per point - per-channel cost is less than a typical industrial pressure
transducer/transmitter.

Pressure Systems, Inc. Model 9116 User’s Manual
Page 3 www.PressureSystems.com
●High accuracy - Model 9116 pressure scanners are capable of accuracies up to
±0.05%. Accuracy is maintained through use of built-in re-zero, span, or multi-point
calibration capabilities. Accuracies are maintained for six (6) months after calibration.
●Low thermal errors - each internal transducer contains an individual
temperature sensor and thermal calibration data for internal use by software
correction algorithms. Thermal errors are reduced as low as ±0.001%FS/ºC over
the calibrated temperature span.
●Re-zero upon demand - an integrated calibration valve allows for automatic re-
zero adjustment calibration of dry gas transducers to null offset drift errors.
●Ease of transducer replacement - factory calibrated transducer assemblies may
be stocked and rapidly replaced in the field. Storage of thermal coefficients
within the transducer allows for ‘plug and play’ transducer replacement.
●Ease of calibration - each Model 9116 module contains a pneumatic
calibration manifold and software commands to automatically perform re-zero,
span, and multi-point adjustment calibrations. New offset and gain coefficients
that result from the most recent calibration may be stored in non-volatile
transducer memory.
●Ease of use - modules have simple command sets and provide engineering units
output. They may interface directly to a desktop or laptop computer or they may
be interconnected into a large network controlled by many types of host
computers.
●Connectivity - use of industry-standard communications network protocols to
control and read data from NetScanner™System modules allows distribution to
the point of measurement and ensures compatibility with third party hardware
and software.
1.2.1 Differences Between Models 9016 and 9116
The all new electronics of the Model 9116 reduces data acquisition noise and capture latency,
while actually improving channel settling time and boosting data throughput. Additionally, the
Ethernet interface has been upgraded to 10BaseT/100BaseT with half and full duplex
capabilities to provide significant flexibility in network configuration. The Ethernet interface is
completely auto-configuring, ensuring the best utilization of network capabilities, while ensuring
the maximum backward compatibility. The trigger circuitry has been upgraded to allow triggering
on positive, negative, or both transitions of the trigger signal. By configuring the Model 9116 to
trigger on both transitions, the Model 9116 can be integrated into existing systems, providing
twice the data throughput for most users, without modification to the system trigger circuit.
The firmware in the Model 9116 implements the Model 9016 command set further simplifying
use with existing systems. In fact, the Model 9116 can be configured to report its identity as a
Model 9016 to ensure compatibility with system software that is sensitive to the reported model
type.

Pressure Systems, Inc. Model 9116 User’s Manual
Page 4 www.PressureSystems.com
Consolidated below are the new commands added to the Model 9016 command set, as well as
differences in existing commands, command parameters, or command responses:
Set Module type alias: w3200 xxxx
See the ‘SET/DO OPTION/FUNCTIONS’ (command ‘w’)’ in Section 3.2.
Configures the Model 9116 to report its model type as Model 9116 or as a
Model 9016 for compatibility with model type sensitive system software.
Set Hardware Trigger Mode: w320x
See the ‘SET/DO OPTION/FUNCTIONS’ (command ‘w’)’ in Section 3.2.
Configures the trigger to response to positive going, negative going, or to
any transition on the trigger input.
Query the Hardware Trigger Mode: q32
See the ‘READ MODULE STATUS’ (command ‘q’)’ in Section 3.2.
The Model 9116 will respond with a 1, 2, or 3 indicating, respectively, that its
trigger is set to respond to a positive going, negative going or to any
transition on the trigger input. The Model 9016 will respond to this command
with an ‘N08’.
Query the Module Hardware Version: w31
See the ‘READ MODULE STATUS’ (command ‘q’)’ in Section 3.2.
The Model 9116 will report the version of hardware present as a floating
point number of the format x.xxxxxx The Model 9016 will respond to this
command with a ‘N08’.
Modifications to existing commands, (See Section 3.2):
In the ‘CONFIGURE A HOST DELIVERY STREAM’ (command ‘c’), the sync delay
can now be set as small as 2 milliseconds and the granularity is 2 milliseconds with
all other values rounded down to the nearest 2 milliseconds. This value was 10
milliseconds in the Model 9016.
In the Set Number of A/D Samples to Average, (command ‘w’). the minimum
value and the default value is 4. The interleaved instrumentation amplifiers utilized
in the Model 9116 allows it to provide the same throughput with one to four
averages. With the quieter electronics of the Model 9116 and no speed advantage
for lower numbers of averaged samples, the minimum and default is set to four.
Valid values are 4, 8, 16, 32, and 64. Other values below 64 are rounded up to the
next valid value listed above.”

Pressure Systems, Inc. Model 9116 User’s Manual
Page 5 www.PressureSystems.com
Additional enhancements to the Model 9116
Software Scan List Speeds:
Software Scan lists can be run as fast as hardware trigger scan lists on the
Model 9116 (~500 Hz. See specification sheet). The Model 9016 was
limited to 100 Hz maximum software trigger scan lists.
Firmware Updates/Boot Loader:
The firmware in the Model 9116 may be updated in situ, over its Ethernet
connection. This is the preferred method for updating the firmware and may
be invoked at any time. (See Section 5.2.1).
The user must connect to the updated module. Establishing a TCP/IP
connection is the last step in validating a successful firmware update. If the
unit is power-cycled four times without establishing a TCP/IP connection, the
firmware update will be tagged as invalid. The Model 9116 contains a
protected resident boot loader that will then take over operation of the
module. The resident boot loader resides in protected memory. It monitors
the state of the firmware and the operation of any downloads. Even in the
event of a power failure during a firmware update, upon return of power, the
resident boot loader will be available, and will establish communications for
downloading new firmware. The user can determine that the Model 9116 is
in boot loader mode by observing that the firmware version reported by the
module is less than 1.0 In boot loader mode, the Model 9116 will return an
‘N08’ in response to the ‘a’, ‘c’, ‘m’, ‘n’, ‘r’, and ‘t’ commands.
1.3 Options
1.3.1 Pressure Ranges
Model 9116 contains sixteen (16) DH200 transducers. These transducers are available with full

The host and each module must have a unique Ethernet Hardware Address (a.k.a. MAC
Address) and a unique IP Address. The Ethernet Hardware address is generally fixed (at
manufacturing time of the Ethernet microprocessor board inside the module). The Ethernet
Hardware address is shown on each module’s label. The Ethernet Intelligent Pressure
Scanners are capable of supporting various methods for IP address assignment, using either
the factory default (static IP addressing) or user-configured Static IP addressing or Dynamic IP
address assignment. Dynamic IP address assignment is through the use of RARP or BOOTP
protocols. Unless your application requires the use of Dynamic IP address assignments, it is
strongly suggested that the module be left configured for the Static IP address protocol. This
default method is typically the simplest method for using the Intelligent Pressure
Scanner.
In the Static IP addressing mode, the module will use a factory default IP address on power-up.
This default address is set to 200.20x.yyy.zzz where x is derived from the module type (0 for
Model 9116 and 1 for 9021/9022) and yyy.zzz is derived from the module serial number. A
similar method is used to calculate each module’s Ethernet hardware address shown on the
module tag. Note that each of these fields (separated by a period, ‘.’) is a decimal
representation of a byte value. This means that each field may have a maximum value of 255.
For Model 9116 modules, the default IP address will be 200.200.y.zzz where y and zzz are
calculated as follows:
y is the integer result of dividing the module serial number by 256.
zzz is the remainder of dividing the serial number by 256 (serial number modulus 256).
These calculations may be verified by checking that y * 256 + zzz equals the original module
serial number. Once a module has powered-up and has assigned itself a default IP address, it
is capable of communications.
An alternate method for assigning an IP address to an Ethernet module is referred to as a
Dynamic IP assignment. This method allows a module to have its IP address dynamically
assigned at power-up by an application running on a node of the TCP/IP or UDP/IP network.
When configured for Dynamic IP address assignment protocols, the reset module will broadcast
its Ethernet hardware (MAC) address on the network in a Dynamic IP request packet. This
broadcast packet identifies the module by its hardware address and requests that a dynamic IP
server application return to it an IP address for use. Once this broadcast message is received,
the dynamic server application will then return an IP address to the module in a dynamic IP
reply packet. Most dynamic IP server applications determine this IP address from a user
maintained file that lists Ethernet hardware addresses with their desired IP address. If modules
are added to the network or module IP addresses are to be changed, the user can simply edit
this configuration file. This capability is common on most UNIX based machines and is also
available (although less common) in some TCP/IP packages available for PC platforms.
Support of the Dynamic IP server protocol is not currently included in the Windows®95/98/XP or
Windows®NT operating systems. In order to allow users of PC platforms to make use of the
Dynamic IP capabilities of the Model 9116, a simple Windows®95/98/XP/NT application was
developed by Pressure Systems which is capable of acting as a Dynamic IP server. This
application is referred to as BOOTP Lite since it actually makes use of the BOOTP protocol that
closely resembles the Dynamic IP request. Like traditional dynamic IP servers, this application
allows the user to configure a file that contains Ethernet hardware addresses and the
corresponding IP address to assign to those devices. This application is free of charge and
capable of running as a background program on Windows®95/98 and NT machines. It may be
downloaded from the PSI home page, www.PressureSystems.com.

Use of Static or Dynamic IP settings may be selected through the Set Operating Options ('w')
command. If you are unsure how your module is configured, check the Tx LED during module
power-up. If it begins to blink periodically after the module power-up, your instrument is
configured for the Dynamic IP assignment protocol. (Tx LED remains OFF in static IP
configuration.) If configured for Dynamic IP assignment, a dynamic server must be configured
on the network to return an IP address to the module. Without an IP address, the host will be
unable to open a TCP/IP or UDP/IP connection to the module.
Note Obtaining the maximum performance of an Ethernet network is a
complex process, involving many tradeoffs and is best performed by
IT professionals or other personnel familiar with Ethernet
parameters, topologies, and equipment capabilities. See Pressure
Systems Web site (www.PressureSystems.com) for application
notes and characteristics of the Model 9116 together with some
hints for its use in high-speed, high-volume Ethernet networks.
Note
After closing the TCP/IP connection to the Model 9116, the host must
wait 10 seconds before re-connecting.
