User Manual / NDA 100/3 TH(S) RG L30 230AC (PoE) LAN

1. Brief Description

The NDA 100/3-2 TH(S) series systems are electronic devices designed to monitor air

temperature and relative humidity. The measurements are made by a high-precision

digital sensor, which can be internal plug-in type (version THS) or external wired

(version TH). Measured values are displayed on a large size LED display, or can also

be viewed remotely on a PC and logged in a database for later review. For this purpose

various communication interfaces are offered: USB, RS485, LAN or PoE LAN and

DataLoggerTH software application is available for download. In case of LAN interface,

user can monitor the measured temperature and humidity on the local Intranet as well,

assuming his PC is located on the same LAN network.

2. Models Available

There are eight different display and four sensor types available. Their selection

depends on intended application. Some applications require displaying temperature

and humidity values without a need of logging measured values. Other may require

remote connection to a PC and data logging.

5. Connections

Power Supply Connection

Important! - Powering of display should be performed after the sensor (internal or

external) and data line cables (if applicable) have been connected.

All display models, except for the version with PoE interface, are designed for input

power 100–230 VAC, 50 / 60 Hz. Flexible power supply cable with EU type 2-prong

plug is attached directly to display from the back panel. To apply power, insert the

power cable plug into the power mains socket.

User Manual / NDA 100/3 TH(S) RG L30 230AC(PoE) LAN

Internal Plug-in Sensor Connection (NDA…THS version)

If your display delivery includes internal plug-in temperature and humidity sensor

(NDA…THS version) insert the sensor device into the opening hole in the bottom side

of display frame. To ensure proper electrical connection the connector of the sensor

must be inserted all the way in. The connector type is 3,5 mm Jack.

External Sensor Connection (NDA…TH version)

If you purchased external sensor “THS Sensor 52 12DC RS485” as an optional

accessory, your display includes input connector for this sensor.

External sensor has a 4-wire cable with EUROCLAMP connector already preinstalled.

Plug this connector into its corresponding connector “P1” (green color connector)

located on the PCB board. All PCB connectors are accessible on the back panel of

large size LED display under a small door plate. The door plate is secured by two

screws which must be removed first. Once you remove the door plate, attach the sensor

cable connector into its corresponding PCB connector. Then insert and screw the door

plate back again. Use the slots in the door plate to route the cable. External

temperature/humidity sensor is powered directly from the large size LED display. No

additional external power supply is necessary.

LAN Ethernet TCP/IP Communication Connection

LAN communication is performed via standard Ethernet TCP/IP protocol. Socket RJ45

is located on the PCB board under a small cover door plate on the back panel of large

size LED display. The door plate is secured by two screws which must be removed

first. Once you remove the door plate, attach the LAN cable connector into its

corresponding PCB connector. Then insert and screw the door plate back again. Use

the slots in the door plate to route the cable.

You can plug standard CAT5 type LAN cable from LAN network port (e.g. switch or

hub) directly into this socket. Please see table below for pinout description.

6. Internet Web Browser Connection

Reading Measured Values

Display has a programmed web server. This feature allows remote connection with

display using a standard PC based Internet web browser (Internet Explorer, Mozilla

Firefox, etc. ) Simply enter the numeric IP address of display into browser’s URL field

(For example: “192.168.0.69”). Browser will connect with the correspond display and

will show its displayed values. See screenshot below.

User Manual / NDA 100/3 TH(S) RG L30 230AC (PoE) LAN

You can view more displays at the same time by opening several tabs on your browser

and entering their corresponding IP addresses into each tab’s URL field.

Configuring Display

When connected with display via its IP address in the web browser, you can enter the

Administrator menu. This can be done by entering the Password in top right field of

the browser window. Default password is “admin”. The password can be changed later

in the administrator menu.

Press Login button or Enter to access the web server configuration menu. The web

server configuration menu will appear in the browser’s window. See screenshot on the

next page.

The configuration menu provides many options to the user. Following is a short

description of each option.

Note: Do not forget to press the Set button after making each change.

Otherwise the change will be discarded.

Offset

-9,9°C to +9,9°C.

Allows user to implement offset correction to measured

values from -9,9°C to +9,9°C. Default value is 0. Please be

cautious when using this feature because sensors are already

calibrated from factory. Under normal circum-stances there

should be no need to change it.

Temperature Units

Celsius / Fahrenheit

Display color

Sets the color of display’s LEDs to red/green/yellow.

Valid for displays with color LEDs only (version RG).

Alarms

- Upper limit

- Lower limit

Allows signalization when values exceed limit values.

Sets the upper limit value for the alarm.

Sets the lower limit value for the alarm.

Color temperature
