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

2.1 Unpacking
Instructions

When the system arrives, inspect the contents for any damage. If
there is damage, contact the delivery company and Teledyne Isco
(or its agent) immediately.

If there is any evidence that any items may have been
damaged in shipping, do not attempt to install the unit.
Please contact Teledyne Isco (or its agent) for advice.

When you unpack the system, check the items against the
packing list. If any parts are missing, contact the delivery
company and Teledyne Isco’s Customer Service Department.
When you report missing part(s), please indicate them by part
number. In addition to the main packing list, there may be other
packing lists for various sub-components.

It is recommended that you retain the shipping cartons as they
can be used to ship the unit in the event that it is necessary to
transport the system.

Please complete the registration card and return it to Teledyne
Isco.

2.2 System Power 2105 modules can be powered by 7 to 26 volts. Some other 2100

system components are limited to a maximum of 16.6 volts
(12 volts typical). The voltage specification is printed on the
serial tag located on the back of the module (refer to Figure 2-1).

Table 2-1 lists the maximum voltages for all Isco 2100 instru­mentation. Regardless of the capabilities of other components,
never attempt to connect a voltage module or cable to a system
using a power supply that exceeds its stated operating range.

Section 2 Installation and Operation

2.3 Installation
Preparation

Injury and/or equipment damage can result from
connecting modules or cables to a power source exceeding
the specified operating voltage range. Check labeling on all
modules and cables for voltage ranges.

All connected system components should share a common
supply ground.

The 2100 Series components are often installed in confined
spaces. Some examples of confined spaces include manholes,
pipelines, digesters, and storage tanks. These spaces may become
hazardous environments that can prove fatal for those unpre­pared. These spaces are governed by OSHA 1910.146 and require
a permit before entering.

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

CAUTION

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.

To unlock the latch, push in the latch release on the connector
side of the module (Figure 2-3).

To lock the latch, push in the latch on the desiccant side of the
module (Figure 2-4).

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 be bent.

Figure 2-4 Locking the latch

CAUTION

Note

2105 Interface Module

Section 2 Installation and Operation

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

2.3.2 Communication
Connectors

When a communication connector is not in use, the con­nector should always be capped. The cap seals the connector

to prevent corrosion, prevent moisture from entering the unit,
and 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.

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

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

2. Insert the carrier and battery into the module.

insert the door.

4. Rotate the door

2.3.3 Installing the Batteries The 2191 battery module requires two lantern batteries. The
figures below show a 6 VDC alkaline battery. Rechargeable 6
VDC lead-acid batteries are also available from Teledyne Isco.

To install the batteries, follow the instructions below.

The batteries should always be replaced as a pair. Never mix
old and new batteries.

Section 2 Installation and Operation

2.4 Stacking Modules The 2105 can be located anywhere within a stack of up to four

2100 Series networked modules. It will draw its power from the
same source as the rest of the stack.

To connect the 2105 with another 2100 Series module:

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. If you are using the metal carrying handle, insert it
between the top two modules, with the handle turned
toward the rear of the stack (opposite the yellow labels).

4. Unlock the 2105’s latch by pressing in on the latch release.

5. Underneath the 2105, remove the cap from the lower com­munication connector and stow it in the holder.

Section 2 Installation and Operation

2.5 Connecting to
Flowlink

Once the system is installed, you will configure it in a new or
existing site using Isco’s Flowlink software.

The 2105 and 2105Ci/Gi Modules require Flowlink version

5.12.052 or later.

The first time you connect to the site, you must connect your
computer directly to the stack using Isco’s RS232 connect cable
or USB port connect cable. Open Flowlink and go to the Connect
screen (Figure 2-8) by either selecting it from the pull down
menu or clicking on the Quick Connect icon.

Make sure the connection Type is Direct, and click on the 2100
Instrument icon to connect. Upon initial connection, Flowlink
creates a site file and adds it to the database. If the system
detects the addition of a new module to an existing site, it will
display the Site Resolution screen (Figure 2-9). Otherwise, it will
display the Site Info screen (Figure 2-10).
