CNTS-N

Description

The CNTS-N, shown below, is CRESTRON’s temperature sensor module that
communicates with the CRESNET II control system via the CRESNET II network. The
sensor measures ambient room temperature and depending on programming, delivers
a reading to a touchpanel for display in one of four formats. The CNTS-N is designed
for wall mounting using a standard single-gang electrical box. The exposed faceplate
and bezel has no discernible features to draw attention to it. Therefore, it can be
discreetly located in a room.

Setup

Identity Code

Each device on the CRESNET II network requires the setting of an identity code (NET
ID). Typically, these codes are recognized by a two-digit hexadecimal number from 03
to FE. However, the CNTS-N is limited to 16 possible hexadecimal numbers (E0 to EF).
The NET ID of each unit must match an ID CODE specified in the “NET.ID” statement
of the CRESNET II SIMPL-I program in order for the device to be addressed properly.

The NET ID of each CNTS-N has been factory set to EF, but may be changed by
removing one or all four of the jumpers. Refer to the illustration below for location of
the CNTS-N jumpers. The table that follows reveals which jumpers need to be
installed for the corresponding NET ID. An ‘X’ in the JUMPER column indicates that
the jumper is installed.

Preparation for Use

For proper installation, complete the following steps in the order provided.

CAUTION: Before making any connections, review latest revision of network
interconnection drawing (Doc. 5411).

NOTE: Before installing the CNTS-N into a single-gang electrical box, verify correct
NET ID setting of the unit.

NOTE: For ease of installation, the white faceplate (CNTS-N sensor) can be removed
from the CNTS-N. Simply disconnect the 3-pin connector.

1. Pass the four network wires of the CNTS-N through the bezel opening

and set the unit into the bezel.

2. Use four connector nuts and connect the four network wires of the

CNTS-N to the network wire in the single-gang electrical box. Refer to
the silk-screening on the back of the CNTS-N for a definition of wire
color (RED-24, WHT-Y, GRN-Z, and BLK-G).

3. Use two screws (supplied) to secure the CNTS-N and bezel to the

single-gang electrical box.

4. If the white faceplate (CNTS-N sensor) was removed, connect the 3-pin

connector and position the faceplate over the installed unit. Faceplate is
secured with magnetic strips.

Programming

SIMPL is CRESTRON’s object-oriented programming language designated for easy
implementation of the control system requirements. The objects that are used in

Workshop

The CRESNET II Workshop is designed to simplify the various operations needed to
program and run a CRESNET II control system. Define the CNTS-N as a CTP-3000
with NET ID equal to EF. If the NET ID has been altered as described in “Identity
Code” on page 2, use this new NET ID in the Workshop. The series of screen
displays (shown on the next page) is accessible from the “Define Network” option of

From the “Define Network” screen of the Workshop (refer to screen 1 of 3), cursor
down to NET ID EF and depress TAB until “CTP-3000” appears in the NET DEVICE
column. Depress F2 to enter the definition. From this screen depress F7 to display the
ANALOG SIGNAL NAME screen (refer to screen 2 of 3). Enter the signal name
coming from the CNTS-N on channel AI1. In the example, the signal name RAW is
used. A signal name must be entered on AI1 for the CNTS-N to report back values
properly. Repeat this procedure for the touchpanel and assign proper signal names
(refer to screen 3 of 3).

NOTE: When entering values into the MXB symbol, type the value and depress the
F10 key before moving off the field. This forces the Workshop to accept the numeric
parameter instead of attempting to convert it to a percentage. Verify that the optional
[DIV] field is left blank; it is not used for this application.

There are four temperature display formats: Fahrenheit without fractional part,
Fahrenheit with fractional part, Celsius without fractional part, and Celsius with
fractional part. To obtain these values from the RAW signal, four different MXB
symbols are used (refer back to the SIMPL-I block diagram). Each MXB output is
routed to an analog output of a touchpanel definition (CTP-3000 in the example).
VisionTools™ for Windows (VTW) is used to properly display the outputs via the
Digital Gauge object.

VisionTools for Windows

NOTE: When displaying results, use any available output on the CTP-3000
definition. The analog outputs in this example are only a sample (i.e., CELSIUS-10
could be routed to AN26 and could join the digital gauge to 26 instead of 4).

When designing touchpanel layout pages, keep in mind that all object properties are
assigned from the respective properties dialog boxes. The “Digital Gauge Properties”
dialog box has a number of tabs for various settings. For this example, the Join and
Design tabs must be accessed (refer to illustration below). The table that follows the
illustration itemizes all the necessary settings for the signals in the block diagram.
