measure parameters of open channel flow streams. It works in
conjunction with Isco’s Flowlink software.

The 2103 Modem can be located anywhere within a stack of up to
three other 2100 Series networked modules, using the same
locking mechanism that connects the 2100 Series modules to
each other. The 2103 is compatible with Isco’s 2150 Area Velocity
flow module, 2110 Ultrasonic flow module, 2101 Field Wizard,
and 2102 wireless module. It is powered by Isco’s 2191 battery
module.

All enclosures are rated NEMA 4X, 6P(IP68). The permanently
sealed enclosures are designed to meet the environmental
demands of many sewer flow monitoring applications. All connec­tions between modules, sensors, and communication cables lock
in place. The locking mechanisms strongly secure the compo­nents and ensure a watertight seal.

WARNING

Avoid hazardous practices! If you use these instruments in
any way not specified in this manual, the protection
provided by the instruments may be impaired; this will
increase your risk of injury.

WARNING

The installation and use of this product may subject you
to hazardous working conditions that can cause you
serious or fatal injuries. Take any necessary precautions
before entering a worksite. Install and operate this product
in accordance with all applicable safety and health
regulations, and local ordinances.

2-1

2103 Modem Module
Section 2 Installation and Operation

hazardous environments that can prove fatal for those unpre­pared. These spaces are governed by OSHA 1910.146 and require
a permit before entering.

2.3 Installation Follow the instructions below to install your 2103 Modem.

2.3.1 Latches - Locking and Unlocking

2.3.2 Communication Connectors

Latches must be operated to stack and unstack the modules in a
Series 2100 stack. The mechanisms are the same for the 2103
Modem and other 2100 Series modules. Detailed instructions
with photos can be found in your 2150 instruction manual.

Take a moment to familiarize yourself with operating the latches.
You must unlock the latch to place the module on top of another
module in a stack. The latch is unlocked by pushing in the latch
release on the right side of the module. To lock the latch, push in
the latch on the left side of the module.

CAUTION

The latch can be damaged by applying too much force. Never
press on both sides at the same time. Do not force the latch if it
is obstructed. While some degree of pressure must be applied
to slide the latch, the ends of the latches should never bend
more than

1

/8".

Note

Latches will “click” when they are fully locked and unlocked.

Connecting the 2103 Modem module involves uncapping and
capping communication connectors. When a communication con­nector is not in use, the connector should always be capped. The
cap will seal the connector to prevent corrosion, and will improve
communications.

When a communication connector is in use, store the cap on the
holder next to the connector. The communication connector will
be sealed by its mating connector.

Detailed instructions and photos can be found in your 2150 or
2110 instruction manual.

2-2

CAUTION

Caps PUSH ON and PULL OFF. Do not rotate the caps to
remove them from the connectors.

Note

For modules to correctly stack and lock together, protective
caps between the modules must be stored on the holders.

2103 Modem Module

Section 2 Installation and Operation

2.3.3 Stacking Modules The 2103 Modem Module can be located anywhere within a stack

of up to three 2100 Series networked modules. It will draw its
power from the battery module located in the stack.

To connect the 2103 with a 2100 Series module, refer to the fol­lowing instructions.

1. On the top of the 2100 Series module, remove the cap and
stow it on the holder. This exposes the communication con­nector on the module.

2. Inspect the module’s communication connector. It should
be clean and dry. Damaged O-rings must be replaced.

3. Unlock the 2103’s latch by pressing in on the latch release
(right side).

4. Underneath the 2103, remove the cap from the lower com­munication connector and stow it in the holder.

5. Lock the latch. Locking the latch correctly seats and aligns
the lower cap in its holder.

6. Position the 2103 over the 2100 Series module. Align the
connectors and lower the 2103 onto the other module.

2.4 Telephone Line Connection (2103 only)

The FCC (Federal Communications Commission) governs com­munications over telephone lines. Your local telephone company
will provide you with the line between the 2103 Modem and your
computer. Contact them for connection information.

The 2103 Modem is in compliance with FCC part 68 rules.
However:

Note

In tests conducted by the Communication Certification Labora­tory, the 2103 Modem did not pass conducted RF testing on
telephone line at 5 MHz, 3V RMS. For details, see international
standard EN 61000-4-6.
In the event of this failure, the modem may be subject to dis­connection.

Accordingly, the FCC requires the following information
be published:

Note

The 2103 Modem is designed to be used on standard device
telephone lines. It connects to the telephone by means of a
standard jack called the USOC RJ-11C. Connection to tele­phone-company-provided coin service (central office imple­mented systems) is prohibited, and connection to party lines

service is subject to state tariffs.

Changes in Attestation Procedure for Plugs and Jacks

Isco Inc. attests that the network interface plugs or jacks used
on this equipment comply with and will continue to comply with
the mechanical requirements specified in Part 58, sub-part F,
specifically the dimensions, tolerances and metallic plating
requirements. The compliance of these connectors will be
assured by purchase specifications and incoming inspection.
Documentation of such specifications and/or inspections will
be provided to the FCC within 30 days of their request for the
same.

Telephone Company Procedures

The goal of the telephone company is to provide you with the
best service it can. In order to do this, it may occasionally be
necessary for them to make changes in their equipment, oper­ations or procedures. If these changes might affect your ser­vice or the operation of your equipment, the telephone
company will give you notice, in writing, to allow you to make
any changes necessary to maintain uninterrupted service.

In certain circumstances, it may be necessary for the tele­phone company to request information from you concerning
the equipment which you have connected to your telephone
line. Upon request of the telephone company, provide the FCC
registration number and the ringer equivalence number (REN);
both of these items are listed on the equipment label. The sum
of all the RENs on your telephone lines should be less than
five in order to assure proper service from the telephone com­pany. In some cases, a sum of five may not be usable on a
given line. Consult your telephone provider.

If Problems Arise: If any of your telephone equipment is not
operating properly, you should immediately remove it from your
telephone line, as it may cause harm to the telephone network.
If the telephone company notes a problem, they may tempo­rarily discontinue service. When practical, they will notify you in
advance of this disconnection. If advance notice is not feasible,
you will be notified as soon as possible. When you are notified,
you will be given the opportunity to correct the problem and will
be informed of your right to file a complaint with the FCC. Con­tact your local telephone service provider if you have any ques­tions about your phone line.

In the event repairs are needed on the 2103 Modem, they
should be performed by Isco Inc. or its authorized representa­tive. For information, contact the Isco Customer Service
Department at [phone] or [phone].

2103 Modem Module

Section 4 Modbus Protocol

Sections 4.1 through 4.5 give an overview of the basic capabilities
and operation of Modbus protocol as it applies to Isco 2100 Series
flow modules.

For a Glossary of Terms and Common Acronyms, see sections 4.4
and 4.5.

For Modbus technical specifications, turn to section 4.6.

4.1 Introduction Modbus is a simple command/response mechanism to read from

and write to specific memory locations called registers. A register
is a holding place for a piece of digital information within the
equipment. There are three standard protocols for Modbus:
Modbus RTU, Modbus TCP/IP, and Modbus ASCII. The Isco 2100
Series devices use Modbus ASCII protocol, the method discussed
in this manual. Modbus ASCII has more flexible communication
timing requirements. Modbus communication for the Isco 2100
Series provides a standard protocol that can be used to retrieve
real-time data from a single module or stack of modules at a site,
or multiple sites, over a wide area. The data can be sent to a
central computer for display, data collection, or process control.

Modbus implementation is independent of Flowlink and cannot
alter the Flowlink-programmed configuration of the module.
Modbus cannot be used to retrieve historical data from a
module’s memory.

Due to the wide variety of configurations that can be made with
Modbus, it is impossible to cover every usable application. This
section will discuss the overall capabilities and operation of
Modbus.

4.2 Operation There are many standard, third party Modbus drivers and OPC

servers that may be used to link a remote Modbus device, such as
a 2100 Series module, to SCADA or process control software,
such as Wonderware™ or Intellution™. The OPC server commu­nicates with the remote instrumentation and accesses registers.
The definition of what information is contained and where (the
register number, or address) is decided by the manufacturer
(Teledyne Isco).

In a 2100 module, the registers hold, but are not limited to, the
current real-time value of the meter’s level, velocity, flow, input
voltage, temperature, and total flow readings, stored in specified
register locations. A list of the 2100 register addresses, and what
parameters are held where, is available in section 4.6.

4-1

2103 Modem Module
Section 4 Modbus Protocol

By accessing these registers you can obtain the current value of
whatever parameter you desire. The reading(s) can then be dis­played or stored wherever you designate as a destination; for
example, a process control computer.

Note

Level, flow, velocity, and temperature data is stored in metric
units only.

Not all registers are limited to read-only data storage. You can
also use some registers for control purposes. For example, by
writing a “1” value to register 24 (“Identify Module” register), you
will tell a 2100 module to light the LED on the front of the
module.

4.2.1 Establishing Communication

4.2.2 Module Addressing When connecting to a site via a Modbus OPC server, you use a

There are several different communications protocols supported
in the 2100 series that require auto-baud rate detection. Because
of this, each time a modbus connection is made, the module uses
a polling mechanism to repeatedly send a command until a
response is received. It may take up to 20 command retries
before the module has identified the baud rate and a response is
received.

dedicated line of communication to that module or stack from the
OPC server, which can be a dedicated communications cable
(direct connection) or a dedicated phone number (modem).

When you are using a direct connection, you are dedicating a
specified COM port on the computer, and that COM port deter­mines the site to which you are connecting.

When you are using a modem, the dedicated line is defined by
the site's phone number.

If you connect more than one 2100 Series module at a site, the
Modbus OPC server, while using the shared communication line
for all of the modules within the network, must have some way to
differentiate between the modules. When sending a command to
a specific module, the command has an address field. This allows
the server software to talk to, as well as control, the specified
module, while ignoring other modules in the same stack or site.

Each module capable of Modbus Protocol communication will
automatically create its own specific ASCII address within the
site, using:

• The model numbers of the modules

• The user-defined module names

4-2

2103 Modem Module

Section 4 Modbus Protocol

4.3 Configurations A variety of configurations can be made with Modbus, either

through direct connection or through a modem.

In the example shown in Figure 4-1, you are direct-connecting a
server PC to two individual 2150s through Modbus, using the
COM ports on the OPC Server, which are directly connected to
the remote 2150s.

Connection to the module is made through the RS-232 communi­cation port on the top of the module.

Note

For low power operation, we recommend connecting the mod­ule(s) to the computer using the straight-through cable (Isco
part number 60-5314-529), which consumes less power,
instead of our standard interrogation cable.

In Figure 4-1, the OPC Server PC must have two COM ports.
Modbus requires one COM port each, for direct connection of
each 2150.

2150

2150

Figure 4-1 Configuration Example (Direct Connection Shown)

The operation sequence for the example above can be summa­rized in the following steps:

2150:

1. 2150s take readings from probes.

2. 2150s store readings (level, velocity, flow rate, etc.) in their
specified registers.

Process Control:

3. The user requests data through Process Control.

4. Process Control asks the OPC server to gather informa­tion.

5. OPC connects to the 2150 stack through the cable (direct
connection), takes register data from the specified 2150,
and populates the OPC server's holding index.

6. Process Control takes data from the OPC server's holding
index and gives data to the user.

Note that Process Control can be either manual or automated in
this example, and that the OPC server and Process Control may
be located physically on the same computer.

4.4 Glossary of Terms ASCII – Short for American Standard Code for Information

Interchange, ASCII is a code that represents English characters
with numbers. Most computers represent text with ASCII code,
making it possible for one computer or device to share data with
another.

2100 modules support Modbus ASCII protocol.

Dedicated Line – A telecommunications path reserved for com­munication between two specified points and not shared among
multiple points.

Modbus Protocol – Modbus Protocol is a messaging structure
used to establish master-slave/client server communications
between intelligent devices. Modbus is a simple
command/response mechanism to read from and write to reg­isters.

OPC – OPC (OLE for Process Control) means open connectivity
via open (free for use) standards. It is a series of software stan­dards specifications that fill a need in automation (like printer
drivers did for Windows), acting as a translator for data trans­mission and process control.

The specification defines a standard set of objects, interfaces, and
methods for use in process control and manufacturing auto­mation applications to facilitate interoperability. There are hun­dreds of OPC Data Access servers and clients.

Registers – Registers are locations in memory that have specific
data stored for retrieval or are used for control functions. A reg­ister is a holding place for a piece of digital information within
the equipment. The definition of what is contained and where
(the registry number, or address) is decided by the manufacturer
(in this case Teledyne Isco).

SCADA – SCADA (Supervisory Control And Data Acquisition)
is a computer system for gathering and analyzing real-time data.
SCADA systems are used to monitor and control plant operation,
or equipment in industries such as telecommunications, water
and waste control, energy, oil and gas refining, and transpor­tation.

The SCADA system transfers the information (for example,
where a leak has occurred in a pipeline), back to a central site,
alerting the home station of the leak, performing necessary
analysis and control (such as determining if the leak is critical),
and displaying the information in a logical and organized
manner.

SCADA systems can be relatively simple, such as one that mon­itors the environmental conditions of a small office building, or
very complex, such as a system that monitors all the activity in a
nuclear power plant or a municipal water system.

Section 4 Modbus Protocol

4.6 Register Specifications All numbers in the Modbus registers are stored most significant

byte first. If the polling device has a byte ordering of least signif­icant byte first (an Intel-based PC, for example), the bytes will
need to be reversed after they are received.

The Modbus ASCII address is used to index the data by modules.

Modbus ASCII address 1 contains information related to the site.
The first register contains a 16-bit integer count of the number of
modules that have data to report. The maximum number of
modules that can be supported is 4.

Modbus ASCII addresses 2 through the number of modules plus
1 contain data from the individual modules.

The Modbus ASCII addresses will be sorted by the model
number, and then by module name, which is entered by the user
through Flowlink. This allows the user to control the ordering of
the addresses and easily predict what data will be in specific reg­isters.

Every measured parameter has a corresponding status and mea­surement time that are updated with each measurement.

The maximum number of supported measurements from all
modules in the system is 28.

The Modbus registers are assigned within 30 seconds after the
2100 module is powered up. To conserve power for the users who
do not use Modbus communications, no Modbus registers will be
updated with sensor readings until a Modbus master communi­cates with the 2100 module.

(1) A write to the Identify module register will cause the module to perform the identify operation which may be a steady

LED for a few seconds or a beep in the Field Wizard.

(2) Setting the Take Reading flag to 1 will cause the module to update the registers with current data readings. It will

be set to zero when the readings have all been updated. This may be used to initiate readings and poll for when
they are ready to be read. It may take up to 50 seconds to update all the readings, depending upon the flow con­ditions. Setting the Take Reading flag to 2 causes an automatic, 15 second update of readings when a Modbus
master is polling the 2100.

(3) The Update Interval specifies an interval in seconds that the registers are automatically updated. It defaults to zero,

which indicates that no automatic updating will occur.

(4) The Active Flag (1-4) bit fields specify what fields/registers are active in the list. This provides support for a maxi-

mum of 64 fields. For example, if bit 0 of register 27 is set, the Level (registers 40,41) is active. If bit 1 of register
27 is set, then the Velocity (registers 55,56) is active. If bit 0 of register 28 is set, the Analog channel 7 (registers
265,266) is active.

This section explains the maintenance requirements of the 2103
Modem.

The 2103 Modem is designed to perform reliably in adverse con­ditions with a minimal amount of routine service requirements.
To keep your system working properly, you should check the des­iccant and channel conditions at regular intervals.

Maintenance intervals are affected by many variables. Humidity
levels obviously affect the service life of the desiccant, and the
amount of debris in the stream can drastically alter the channel
conditions.

Experience is often the best tool to use when establishing
minimum maintenance intervals for your system. Until you have
gained an understanding of the AV Module’s operation under dif­fering environmental conditions, a weekly maintenance interval
is recommended.

water, and a mild detergent. Do not use an abrasive cleanser, or
you might scratch the surface of the case.

Before cleaning, make sure that all the protective connector caps
are in place to avoid damage to any of the connectors. You should
also ensure that no water or cleanser enters the desiccant unit.

Section 5 Maintenance

5.3 Desiccant The 2103 Modem uses desiccant to protect the internal compo-

nents from moisture damage. The cartridge is filled with indi­cating silica gel, which is blue or yellow when dry. As the
desiccant becomes saturated, the color changes from blue to pink,
or from yellow to green. Replace the desiccant before the entire
length of the cartridge turns pink or green.

5.3.1 Replacing the Desiccant

Collar

Cartridge

5.3.2 Reactivating the Desiccant

The desiccant is contained in a cartridge located on the left side
of the 2103 Modem. To remove the cartridge, unscrew the collar
and slide the cartridge out of the 2103 Modem. The clear tube
reveals the silica gel desiccant inside.

To replace the silica gel desiccant:

1. Hold the cartridge upright with the collar at the top.

2. As shown in the margin, push the collar off the cartridge.

3. Empty the saturated silica gel beads or granules.

4. Fill the tube with new (Isco P/N 099-0011-03) or reacti­vated (see section 3.3.2) silica gel desiccant.

5. Press the collar onto the tube.

6. Slide the cartridge into the 2103 Modem. Tighten the collar
to seal the cartridge in place.

Silica gel beads and granules of desiccant can be reactivated.

CAUTION

Desiccant may produce irritating fumes when heated. Observe
the following precautions:

• Use a vented oven in a well ventilated room.

• Do not remain in the room while the regeneration is taking
place.

• Use the recommended temperature. Avoid heating the
desiccant at higher than recommended temperatures.

5-2

There is the potential of irritating fumes coming from the des­iccant during reactivation. Because of this, we urge you to use
caution, and to heat the desiccant in a well ventilated room.
Material Safety Data Sheets are in the back of this manual.

The desiccant’s ability to remove moisture may lessen with each
saturation/reactivation cycle, resulting in a need for more fre­quent service. After several cycles, the desiccant may no longer
be effective as it saturates too quickly. At this point, replace the
desiccant.

2103 Modem Module

Section 5 Maintenance

Silica gel To reactivate the silica gel desiccant, pour the spent desiccant

into a heat resistant container. Never heat the cartridge
assembly; it will melt. Heat the silica gel in a vented convection
oven at 212° to 350°F (100° to 175°C) for two to three hours, or
until the blue or yellow color returns. Allow the desiccant to cool
and store it in an airtight container until ready for use.

5.4 Hydrophobic Filter If the 2103 Modem module is submerged, a hydrophobic filter

prevents water from entering the desiccant cartridge. Any
amount of water will plug the filter and it must be replaced so
the case will be reliably ventilated.

To remove the hydrophobic filter, grasp the filter and pull it from
the desiccant cartridge collar. The filter is only held in place by
its friction fitting; rocking it back and forth while pulling may
help. Firmly press the replacement filter (Isco P/N 60-2005-003)
in place.

If the hydrophobic filter frequently requires replacement, you
should consider relocating the modules so they are better pro­tected. Alternatively, replace the existing hydrophobic filter with
the extension accessory package included with your unit. Follow
the instructions above to remove and replace the filter. Locate
the other end of the tubing in a dry location and secure it.

5.5 O-Rings The communication connectors on the top and bottom of the 2103

Modem contain O-rings that need periodic lubrication and
replacement. The maintenance kit described in section 3.2 con­tains O-rings and silicone lubricant.

Whenever you replace the O-rings, or have removed them from
the connectors for some reason, you should lubricate the O-rings
by applying lubricant around the circumference of the ring.

Note

Do not use petroleum-based lubricants. Petroleum-based
lubricants will cause the O-ring to swell and eventually deterio­rate. Aerosol silicone lubricant sprays often use petroleum
based propellants. If you are using an aerosol spray, allow a
few minutes for the propellant to evaporate before proceeding.

5.6 How to Obtain Service The internal components of the 2103 Modem are not user-ser-

viceable. The case is completely sealed to protect the internal
components. To repair the unit, the case must be broken open
and replaced. If you think your module requires repair, contact
Isco’s Technical Service Department.

Corresponding with a Teledyne Isco Technical Service Represen­tative can often resolve the problem without the need to return
the item. If the difficulty cannot be resolved you will be issued a
Return Authorization Number (RAN) and information on
returning it to the factory.

Human Toxicology Silica gel is a synthetic amorphous silica not to be confused with crystalline silica.
Epidemiological studies indicate low potential for adverse health effects. In the activated form, silica gel
acts as a desiccant and can cause a drying irritation of the mucous membranes and skin in cases of severe
exposure. Multisorb Technologies Inc. knows of no medical conditions that are abnormally aggravated by
exposure to silica gel. The primary route of entry is inhalation of dust.
