3 General safety information
 Read these operating instructions before using the OTT netDL for the first time!
Become completely familiar with the installation and operation of the OTT
netDL and its accessories!
Note any additional information on dangers given within the individual work
steps.
Only use the OTT netDL and its accessories in the manner described in these
operating instructions.
 Make sure that the installation site is sufficiently protected against moisture
(IP 41 type of protection)!
 Select the installation site so that the ambient temperature never exceeds or
falls below the allowable temperature range of –40 °C to +70 °C (for device
versions B... and C... : –30 °C to +70 °C)!
 Install the OTT netDL in a closed control cabinet or in a fire protection cabinet!
If the power supply of OTT netDL is a low power source (LPS), this is not
necessary.
 Do not open the OTT netDL unit! Sensors, communication equipment, power
supply, switching contacts, or additional components are connected only
through the screw terminal strips/9-pin Sub-D connectors accessible from
outside.
 Operate an OTT netDL unit with built-in GSM modem (device versions B...
and C...) only with the GSM cellular radio antenna connected.
Minimum clearance between antenna and unit: 20 cm!
 Before connecting the power supply, check that all wires are properly attached
to the screw terminal strips and/or 9-pin Sub D connectors.
It is essential to comply with the electrical limits given in the "Technical Data"
section.
 Connect the OTT netDL only to a power supply providing less than 28 VDC.
Protect the feed line of the supply voltage with a safety fuse (10 A /fast)!
 Always use a galvanically isolated safety extra-low voltage (SELV) for
mains supply.
 Do not make any changes or retrofits to the OTT netDL!
 Have a defective OTT netDL checked and repaired by the OTT repair center.
Under no circumstances carry out any repairs yourself.
Please note: With a nearly full data memory in the OTT netDL
unit, it may take a few minutes after an interruption of the oper-
ating voltage until communication is possible again!

4 About these operating instructions
These operating instructions (revision "03-0912") cover the OTT netDL software
versions
 OTT netDL firmware (operating system) from V 2.25.0
 OTT Data Logger Operating Program from V 1.52.0
The version of the operating program can be found via the "Info"
feature in the "Help" menu.
The version of the OTT netDL firmware is found in the master data window (refer
to online help) after the OTT netDL configuration has been read into the operating
program.
In Chapter 12 "Updating the OTT netDL firmware" you will find a description on
how to update the OTT netDL firmware.

5 Introduction
The OTT netDL unit is an Internet protocol (IP) enabled datalogger that is especial-
ly designed for hydrometry, meterology and environmental measuring technology.
It is available in two models: OTT netDL 500 and OTT netDL 1000.
The standard version of each datalogger provides four physical input channels, an
LCD display, and a jog shuttle. (
The jog shuttle is a special operating button that
can be rotated and pressed.)
On request, the OTT netDL is available including
different expansion cards (OTT netDL 500: 2 slots; OTT net DL 1000: 3 slots) and
a built-in GSM modem. Additionally, OTT netDL 1000 has an Ethernet interface
as well as a second serial interface.
Plug-in screw terminal strips allow easy connection of sensors and power supply
without having to open the unit. Two LEDs show the operating states of the data-
logger as well as of the GSM modem.
Configuration and parametrization are carried out using the "OTT Data Logger
Operating Program" PC software. This software allows the system to be conve-
niently and flexibly tailored to a wide range of measurement requirements of a
station.
All inputs are equipped with an internal overvoltage protection. The very low
power consumption allows the unit to be operated with solar power without
problem.
Using the internal or external GSM modem (cellular radio modem), remote data
communication as well as remote parametrization may be done over the GSM
cellular radio network (GSM = Global System for Mobile Communications).

The remote data communication can be optionally carried out via a dial-up tele-
phone connection, by SMS text messages, or using the packet-based GPRS mobile
radio transmission service (General Packet Radio Service). The OTT netDL 1000
unit also provides remote data communication through the Ethernet interface.
Similarly, remote data communication may be carried out via a satellite trans-
mitter or a cable modem.
Furthermore, the OTT netDL has individually configurable alarm and action manage-
ment: If particular events occur, OTT netDL independently generates an alarm and
sends this via a modem e.g. to a control center. It is also possible to control exter-
nal devices via switching contacts.
For both OTT netDL models, optional voice announcer functionality is available. It
allows measured values and alarm messages to be announced through a dial-up
connection. This functionality requires a voice-enabled modem (analog or ISDN)
or the internal GSM modem (C version code…) to be used. Depending on the
particular requirements, OTT will configure custom announcer texts or provide
standard voice modules for individually compiling the announcer texts. When an
external analog modem is used, measured values may also be announced on site.
