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

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].

2.4.1 Modem Cable Connection

After you have installed the 2103 on the stack, you need to attach
the modem cable so the module can be connected to a phone line.

Remove the connector cap from the 5-pin circular modem cable
connector on the right hand side of the 2103. Attach the modem
cable to the connector (Figure 2-1), and then connect the other
end of the modem cable to a standard telephone jack (USOC
RJ-11C).

Figure 2-2 2103 Modem Cable Connector

If desired, the 2103 can be connected to a standard telephone line
by attaching the telephone line cable to a connector that mates
with the 2103’s 5-pin circular modem cable connector (Figure
2-2). Be sure that you have a water tight seal on your wire con­nections.

For your reference, the modem cable uses a 5-pin amphenol
socket, MS3106A-5S.
