2105 Interface Module

Note

Section 1 Introduction

This instruction manual is designed to help you gain a thorough
understanding of the operation of the 2105, 2105Ci, and 2105Gi
Interface Modules. Teledyne Isco recommends that you read this
manual completely before placing the equipment into service.

Information in this manual pertains to both the 2105 module and
2105Ci/Gi cellular modem modules. Specific differences between
the modules are identified wherever they occur.

Part numbers for ordering associated equipment and accessories
can be found in Appendices A and B, near the end of this manual.

1.1 Product Description The 2105 Interface Module is designed to store data from Isco’s

2100 Series flow modules and Pulse Doppler flow meters. The
2105 also provides Modbus input, sampler interface, and rain
gauge and SDI-12 input. It works in conjunction with Isco’s
Flowlink software.

If you have ordered any version of the Isco Model 677 logging
rain gauge (Isco rain gauge and 2105 module combination),
your system includes the rain gauge interface cable.

The 2105 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 2105 is compatible with Isco’s 2150 Area Velocity flow
module, 2110 Ultrasonic flow module, 2160 LaserFlow module,
2101 Field Wizard, 2103 landline modem module, 2103Ci cellular
modem module, and 2102 wireless module. The stack can be
powered by any of several power options offered by Teledyne Isco,
such as the 2191 battery module.

All enclosures are rated NEMA 4X, 6P (IP68). The permanently
sealed enclosures are designed to meet the environmental
demands of many 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.

Section 2 Installation and Operation

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.

Follow the instructions below to install your 2105 module. Most
of these instructions are similar for the 2105Ci and 2105Gi.
Where there are specific differences between the modules, they
are identified.

2.3.1 Latches - Locking and
Unlocking

Latches must be operated to stack and unstack the modules, and
to gain access to the vent screw. The latch is normally locked, but
you must unlock it to install the module on top of another module
in a stack.

Section 2 Installation and Operation

2.5.1 Modem Site
Connection

To begin using the 2105’s cellular modem, you must set up the
modem’s operation on the Modem screen.

The digital cellular modem provides Serial Over IP (IP) commu­nication. This mode of communication is much faster, and does
not require analog infrastructure. Phone service with a static IP
address, rather than a land line, provides efficient communi­cation.

CSD communication is being phased out by Verizon. As of July
2012, no new CSD lines can be added, and all CSD service is
scheduled to end in 2014.

The default TCP port is 1700, but you can change the port
number if necessary.

If using a 2105Gi, you must enter the Access Point Name (APN)
information provided by your cellular service carrier. The Out­bound box will only become active if you are using Flowlink Pro
software and have set up the pushed data function (refer to

Pushed Data Capability (cellular modules), Section 2.8).

communication (2105Ci shown)

If your cellular service is set up and ready for use through your
service provider, you can now connect to your interface module
via cellular connection.

For systems using the cellular modem, a Power Control method
is highly recommended to conserve battery power (refer to
Section 2.6).

2-13

2105 Interface Module

Note

Section 2 Installation and Operation

2.6 Power Conservation
(cellular modules)

If you are using a cellular module, you may want to conserve
battery power by setting up a Power Control method using the
equation builder. Rather than have the internal modem continu­ously enabled, you can specify conditions for when it is powered
up. To begin configuring the power settings, click the Wireless
Power Control tab. Then click on Set Equation. (The Set Wireless
Schedule button is not intended for use with cellular modules.)

Power Control applies only to the internal modem, not the
module itself. However, during the specified periods when the
modem is disabled, you will only be able to communicate with
the module via direct connection.

Sampler Interface). For more information about sampler
enabling and rain events, refer to your Flowlink Help menu.

Two 2105/rain gauge interconnect cables are available: one for
the Teledyne Isco model 674 rain gauge, and one for non-Isco rain
gauges. See Figure 2-30 for cable information.

If you have ordered any version of the Teledyne Isco Model
677 logging rain gauge (Isco rain gauge and 2105 module
combination), your system includes the rain gauge interface
cable.

Measurement units are selectable on the Rainfall tab’s pull down
list (Figure 2-18). Total rainfall data storage is set up like any
other parameter in Set Up Data Storage... However, the total
rainfall on the measurement tab resets to zero at midnight.

2.11 Sampler Interface The 2105 can control a connected Teledyne Isco wastewater

sampler. Two interconnect ‘Y’ cables are available: one for the
4700 refrigerated sampler, and one for all other Teledyne Isco
samplers. See Figure 2-30 for cable information.

From the Sampler tab (Figure 2-19), you can choose to keep the
sampler enabled or disabled, or enable the sampler based on con­ditions. To keep the sampler enabled once it has been triggered,
select the Latch check box.

For more information about sampler enabling and rain events,
refer to your Flowlink Help menu.

The 2105 can pace the sampler based on total flow volume. Be
sure that the sampler’s programmed sampling interval, com­bined with the 2105’s Flow Pulse interval, produce the desired
volume interval.

2.12 Sampler
Pass-Through Mode

The 2105 module offers a “Pass-Through” mode which, when acti­vated, allows you to remotely access a 6712 or Avalanche
sampler’s configuration settings.

The Pass-Through feature allows full remote control of the
sampler’s keypad functions. With this access, you can view or
modify all program and configuration settings, and also view
stored reports, current status, and data values. You can start a
program, modify the current program, or stop an active program.
This feature is helpful for applications such as storm monitoring
where the need to adjust program operation due to pending
events is often necessary.

If you use this feature, it is important that you follow the steps
in Table 2-2. Make sure you close all active menus and close
the terminal emulation connection to the sampler, or the 2105
will remain in Pass-Through mode. While in this mode, the
2105 will be unable to push data, send alarms, or accept
incoming communications.
If you are using CSD service and need to terminate the Pass
Thru mode, log back into the terminal emulation program and
follow steps 10-14 in Table 2-2.
If you are using SOIP service and you lose communication
with the module while in Pass-Through mode, you will need to

2-21

visit the site and cycle the power to restore wireless communi­cations.

To use this feature, two cables are required (Figure 2-21). You
will need the 2105-to-sampler ‘Y’ cable, and the 2105-to-sampler
single cable that connects the sampler cable to the computer port
of the sampler.

Figure 2-21 Cable connections for sampler Pass-Through Mode

A terminal emulation program, such as HyperTerminmal or Tera
Term, is also required. The following configuration screen
examples are from HyperTerminal, but the process and

2.13 Pulse Doppler Devices The 2105 can receive flow data (QMain, Velocity, and Depth)

from a connected Pulse Doppler device, including the standard
depth ADFM, the H-ADFM (large channels), the accQmin
(shallow water measurement), and the Hot Tap (closed and pres­surized pipes). Teledyne Isco offers a 25-foot ‘Y’ cable (see Figure
2-30), for connection to a Pulse Doppler instrument.

Pulse Doppler input and Modbus input (see Section 2.14) can­not be used simultaneously in the same system.

The 2105Ci/Gi can push Pulse Doppler ensemble data to a
Flowlink Pro database server. Pulse Doppler support and pushed
data functions are activated by selecting the check box on the
ADFM tab (Figure 2-26). The pushed data function is configured
from the Data tab (Figure 2-16). See Flowlink Pro’s Help menu
for detailed instructions on pushed data setup. Make sure that
the baud rate you have selected from the pull down list matches
that of the instrument.

Section 2 Installation and Operation

2.14 Modbus Input The 2105 module is capable of receiving data from devices using

Modbus ASCII or Modbus RTU protocol.

The 2105 Modbus input function supports ASCII and RTU pro­tocols, but the RS-232 can only interface directly with one input.
The RS-485 will require a converter, but it can support up to two
inputs. Teledyne Isco offers an RS-232 to RS-485 converter.

You must set up and configure your monitoring/control system
and Modbus device(s) before adding the 2105 module.

Modbus and Pulse Doppler input (see Section 2.13) cannot be
used simultaneously in the same system.

From the Modbus tab, configure the protocol. To add a device to
the system, click New Device.

2.14.1 4200 and 6700 Series
Measured Data

All 2100 modules have Modbus output capability. For an over-
view of Modbus principles and an explanation of Modbus out­put operation as it applies to 2100 modules, turn to
Section 3 Modbus Protocol and 2100 Output.

This section is specific to 4200 Series flow meters and 6700
Series samplers. For overall Modbus input instructions, begin by
reading Section 2.14 Modbus Input.

The 2105 module can capture, log, and push data from a 4200
Series flow meter or 6700 Series sampler. The 2105 interfaces
with the instrument through a simulated Modbus connection.
4200/6700 data parameters must be entered as Modbus param­eters.

Data stored in the 4200/6700 may not exactly match the same
data stored in the 2105 because the 4200/6700 stores the average
of readings per interval, while the 2105 will retrieve only the last
measurement taken for each interval. Because of this difference
in data storage, the 4200/6700 clock should be set slightly ahead
of the 2105 clock in order for the 2105 to capture recently
updated parameters.

The interface will not work unless the flow meter or sampler's
serial output function is activated. By default, 4200 flow meters
and 6700 Series samplers do not have the serial output function
activated.

battery module. The 2105Gi is compatible with Teledyne Isco’s
2150 Area Velocity flow module, 2110 Ultrasonic flow module,
2160 LaserFlow module, 2101 Field Wizard, and 2102 Wireless
module, 674 Rain Gauge, and accQmin Flow Meter.

4.2 SIM Card The data transmission capabilities of the 2105Gi are dependent

upon the type of service plan you have through your cell phone
service provider. The service parameters, or provider, can be
changed by simply replacing the SIM card in your 2105Gi. Check
with your service provider to verify what data transmission tech­nologies are available for your use.

To access the SIM card slot, turn the 2105Gi module over. On the
bottom is the round metal cover of the compartment holding the
card. The card is most easily removed by placing a coin in the
center slot and turning counterclockwise (Figure 4-1).

Section 5 Modbus Protocol and 2100 Output

Sections 5.1 through 5.5 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 5.4
and 5.5.

The 2105 Interface Module is capable of receiving Modbus
input using ASCII or RTU protocol. For 2105 Modbus input
configuration, see Section 2.14 Modbus Input.

5.1 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. For data output, the Isco 2100 Series devices use
Modbus ASCII protocol, the method discussed in this section.
Modbus ASCII has more liberal 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 output 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.

5.2 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.

5-1

2105 Interface Module

Note

Section 5 Modbus Protocol and 2100 Output

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.

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. For register definitions for individual modules, including
read/write designation, contact Teledyne Isco.

5.2.1 Establishing

Communication

Modbus Protocol Setup

5.2.2 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.

The communication settings for Modbus protocol are as follows:

Baud: 9600

Bits: 8

Parity: None

Stop Bits: 1

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.

Section 5 Modbus Protocol and 2100 Output

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

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

through direct connection or through a modem.

In the example shown in Figure 5-1, you are direct-connecting a
server PC to two individual 2100 sites through Modbus, using
the COM ports on the OPC Server, which are directly connected
to the remote sites.

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

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 5-1, the OPC Server PC must have two COM ports.
Modbus requires one COM port each, for direct connection of
each site.

Figure 5-1 Configuration example (direct connection shown)

5-3

2105 Interface Module
Section 5 Modbus Protocol and 2100 Output

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.

5.4 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. For output, 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).

Section 5 Modbus Protocol and 2100 Output

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.

5.5 Common Acronyms ASCII – American Standard Code for Information Interchange

DCS – Distributed Control Systems

TCP/IP – Transmission Control Protocol/Internet Protocol

5.6 Register Specifications

- 2100 Output

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 the module in
the stack (N) minus 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.

5-5

2105 Interface Module

Note

Section 5 Modbus Protocol and 2100 Output

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.

In a system consisting of more than one module, the “top”
module (the one being queried) is holding the Modbus data for
the entire system. Although most registry locations are the
same for all 2100 Series modules, some will be determined by
the specific module being interrogated, and its firmware ver­sion.

Section 6 Maintenance

6.1 Overview The 2105 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 module’s operation under dif­fering environmental conditions, a weekly maintenance interval
is recommended.

6.1.1 Cleaning The module case may be cleaned using a soft cloth, warm 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.

6.2 Desiccant The 2105 uses desiccant to protect the internal components 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.

Section 6 Maintenance

6.2.1 Replacing the

Desiccant

6.2.2 Reactivating the

Desiccant

The desiccant is contained in a cartridge located on the side of
the 2105. To remove the cartridge, unscrew the collar and slide
the cartridge out of the 2105. 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 6.2.2) silica gel desiccant.

5. Press the collar onto the tube.

6. Slide the cartridge into the 2105. Tighten the collar to seal
the cartridge in place.

Silica gel beads and granules of desiccant can be reactivated.

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.

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

6-2

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.

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.

2105 Interface Module

Note

Section 6 Maintenance

6.3 Hydrophobic Filter If the 2105 is in a humid location or submerged, a hydrophobic

filter prevents water from entering the desiccant cartridge. Any
amount of water will plug the filter and it must be rinsed with
clean water and allowed to dry, or replaced to prevent internal
damage to the module.

Remove the hydrophobic filter with a
screw in the replacement filter.

If the hydrophobic filter frequently requires replacement, con­sider relocating the modules so that they are better protected.

/8" or 16mm socket. Gently

6.4 O-Rings The communication connectors on the 2105 contain O-rings that

need periodic treatment with silicone lubricant and replacement.

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.

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.

6.5 How to Obtain Service The internal components of the 2105 are not user-serviceable.

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.

Considered an ocular irritant

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.
