Industry Compliance
As of the date of manufacture, the C2N-RTHS has been tested and found
to comply with specifications for CE marking and standards per EMC and
Radiocommunications Compliance Labelling.
NOTE: This device complies with part 15 of the FCC rules. Operation is
subject to the following two conditions: (1) this device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
Network Wiring
CAUTION: In order to ensure optimum performance over the full range
of your installation topology, Crestron Certified Wire, and only Crestron
Certified Wire, should be used. Failure to do so, may incur additional
charges if support is required to identify performance deficiencies as a
result of using improper wire.
CAUTION: Provide sufficient power to the system. Insufficient power
can lead to unpredictable results or damage to the equipment. Please use
the Crestron Power Calculator to help calculate how much power is
needed for the system. Refer to (http://www.crestron.com/calculators).
4 •Remote Temperature/Humidity Sensors Operations & Installation Guide – DOC. 6232A

Crestron C2N-RTHS Remote Temperature/Humidity Sensor
CAUTION: Use only Crestron power supplies for Crestron equipment.
Failure to do so could cause equipment damage or void the Crestron
warranty.
NOTE: When installing network wiring, refer to the latest revision of the
wiring diagram(s) appropriate for your specific system configuration,
available from the Crestron website.
NOTE: For larger networks (i.e., greater than 28 network devices), it
may be necessary to add a Cresnet Hub/Repeater (CNXHUB) to maintain
signal quality throughout the network. Also, for networks with lengthy
cable runs or varying types of network devices, it may be desirable to add
a hub/repeater after only 20 network devices.

When calculating the wire gauge for a particular Cresnet run, the length of
the run and the Cresnet power usage of each Cresnet unit to be connected
must be taken into consideration. If Cresnet units are to be daisy-chained
on the run, the Cresnet power usage of each network unit to be daisy-
chained must be added together to determine the Cresnet power usage of
the entire chain. If the unit is a home-run from a Crestron system power
supply network port, the Cresnet power usage of that unit is the Cresnet
power usage of the entire run. The length of the run in feet and the Cresnet
power usage of the run should be used in the following resistance equation
to calculate the value on the right side of the equation.
Resistance Equation
R = Resistance (refer to the following table).
L = Length of run (or chain) in feet.
P = Cresnet power usage of entire run (or chain).
R < L x P

The required wire gauge should be chosen such that the resistance value is
less than the value calculated in the resistance equation. Refer to the
following table.
Wire Gauge Values
RESISTANCE WIRE GAUGE

6 18
10 20
15 22

8.7 Tripled CAT5
NOTE: All Cresnet wiring must consist of two twisted pairs. One twisted
pair is the +24V conductor and the GND conductor, and the other twisted
pair is the Y conductor and the Z conductor.
NOTE: When daisy-chaining Cresnet units, strip the ends of the wires
carefully to avoid nicking the conductors. Twist together the ends of the
wires that share a pin on the network connector, and tin the twisted
connection. Apply solder only to the ends of the twisted wires. Avoid
tinning too far up the wires or the end becomes brittle. Insert the tinned
connection into the Cresnet connector and tighten the retaining screw.
Repeat the procedure for the other three conductors.
Installation
1. Ensure that the location is not close to a heat or humidity
source and away from direct sunlight, skylights, and windows.
2. Locate an area on the wall that is free of miscellaneous wiring
and studs.
3. Make a small hole near the center of the designated mounting
site to verify that the location is suitable.
4. Drill or cut a 1 in (2.54 cm) diameter circular hole in the wall
at the desired position.
6 •Remote Temperature/Humidity Sensors Operations & Installation Guide – DOC. 6232A

Crestron C2N-RTHS Remote Temperature/Humidity Sensor
5. Route the Cresnet wires to the sensor. Use the four wire nuts
included to connect the wires (red to red, white to white, blue
to blue, and black to black).
6. Press fit the sensor into the hole; the clips on either side of the
sensor hold it in place.
NOTE: The face of the sensor may be painted or wallpapered to match
the wall. However, keep the small gap around the outer edge clear of any
obstructions.
Identity Code
Refer to
the note
on page
16 for a
definition
of
Viewport.
Every equipment and user interface within the network requires a unique
identity code (Net ID). These codes are two-digit hexadecimal numbers
from 03 to FE. The Net ID of each unit must match an ID code specified
in the SIMPL Windows program. The Net ID of the C2N-RTHS has
been factory set to 2B. The Net IDs of multiple C2N-RTHSs in the same
system must be unique. Net IDs are changed from a personal computer
(PC) via the Crestron Viewport.
There are two different methods—Method A or Method B—for setting the
C2N-RTHS Net IDs:
Method A (Cresnet address-settable ID), described on the next page,
applies to C2N-RTHSs in a Cresnet system with a CNX control system or
Operations & Installation Guide - DOC. 6232A Remote Temperature/Humidity Sensor •7

Remote Temperature/Humidity Sensor Crestron C2N-RTHS
with a 2-Series control system upgrade file (CUZ) version prior to 3.008,
but can be used with later versions of firmware and requires that a single
unit be the only network device connected to the control system.
Method B (Touch Settable IDs), which begins on the next page, applies to
C2N-RTHSs in a Cresnet system with 2-Series control system upgrade
file (CUZ) version 3.029 or later. These upgrades enable Touch Settable
ID (TSID) functionality, which makes it possible for the control system to
recognize a network device via its serial number, which is stored in the
device’s memory. This method does not require that any devices be
disconnected from the network; Net IDs may be set with the entire
Cresnet system intact. This method requires the use of the Crestron
Viewport version 3.35 or later.
Use the appropriate method to set the C2N-RTHS Net ID.
Method A (Cresnet address-settable ID)
1. Ensure that the C2N-RTHS is the only device connected to the
control system.
2. Open the Crestron Viewport.
3. From the Viewport menu, select Functions | Set Network ID.
The software checks the baud rate and then opens the "Set
Network ID" window.
4. In the "Set Network ID" window, select the C2N-RTHS from
the Current Network Devices text window.
5. Select the new Net ID for the C2N-RTHS from the Choose the
new network ID for the selected device (Hex): text box.
6. Click Set ID to initiate the change. This will display the "ID
command has been sent" window.
7. In the "Command Complete" window, click OK.
8. In the Current Network Devices text window, verify the new
Net ID code.
9. In the "Set Network ID" window, click Close.
NOTE: The new Net ID code may also be verified by selecting
Diagnostic | Report Network Devices in the Viewport (alternately, select
F4).
8 •Remote Temperature/Humidity Sensors Operations & Installation Guide – DOC. 6232A

Crestron C2N-RTHS Remote Temperature/Humidity Sensor
10. Repeat this procedure for each C2N-RTHS to be added to the
system.
Method B (Touch Settable IDs)
Touch Settable ID (TSID) modes are supported through the use of the
pinhole setup button and a red LED. These procedures are for TSID-
enabled network devices during the initial configuration of a Cresnet
system or when such devices are being added/replaced. Before using this
method, you should have a list of all current network devices and their Net
IDs, to avoid assigning duplicate IDs.
1. Ensure that all C2N-RTHS are connected to the control
system.
2. Open the Crestron Viewport version 3.35 or later.
3. From the Viewport menu, select Functions | Assign Cresnet
ID by Serial Number. The “Set Net ID by TSID” window
appears. The window is first displayed with the data fields
empty. (Refer to the following figure.)
“Set Net ID by TSID” Window
4. Click on the Search for Touch Settable Devices button. The
system searches the network and lists all TSID-enabled devices
Operations & Installation Guide - DOC. 6232A Remote Temperature/Humidity Sensor •9

Remote Temperature/Humidity Sensor Crestron C2N-RTHS
found. The list is similar to the report produced by pressing F4
(Report Network Devices); the first eight digits of each line
constitute the TSID number (hexadecimal form of the serial
number).
5. As you enter either the serial number or TSID number of the
device that requires a change, the corresponding TSID or serial
number automatically appears in its appropriate field, and the
list scrolls to and highlights the device listing. The listing
should show the device’s current Cresnet ID.
6. Enter the Cresnet ID that the device should be set to and click
OK. The number you enter should appear on the list.
CAUTION: This function does not prevent you from setting duplicate
IDs. Be sure to check current assignments before entering the desired
Cresnet ID number.
Serial Number to TSID Conversion
This utility is useful in a case where there are multiple devices of the same
type on a network, you need to locate a particular one, you know the TSID
but not the serial number, and your site installation list is based on device
serial numbers. In this (or the reverse) situation, do the following:
1. Open the Crestron Viewport.
2. From the Viewport menu, select Functions | Serial Number
ÅÆ TSID Conversion Tool. The “Serial Number ÅÆTSID
Conversion Tool” window is displayed.
“Serial Number to TSID Conversion Tool” Window

Uploading and Upgrading
NOTE: Crestron recommends that you use the latest software and that
each device contains the latest firmware to take advantage of the most
recently released features. Please check the Crestron website
(http://www.crestron.com/updates) for the latest versions of software and
firmware. New users are required to register to obtain access to this site.
Assuming a PC is properly connected to the entire system, Crestron
programming software allows the programmer to upload programs and
projects after their development to the system and network devices.
However, there are times when the files for the program and projects are
compiled and not uploaded. Instead, compiled files may be distributed
from programmers to installers, from Crestron to dealers, etc. Even
firmware upgrades are available from the Crestron website as new
features are developed after product releases. In those instances, one has
the option to upload via the programming software or to upload and
upgrade via the Crestron Viewport.
Operations & Installation Guide - DOC. 6232A Remote Temperature/Humidity Sensor •15

Remote Temperature/Humidity Sensor Crestron C2N-RTHS
NOTE: The Crestron Viewport is available as a pull-down command
from SIMPL Windows and VT Pro-e (Tools | Viewport) or as a
standalone utility. The Viewport utility accomplishes multiple system
tasks, primarily via an RS-232 or TCP/IP connection between the control
system and a PC. It is used to observe system processes, upload new
operating systems and firmware, change system and network parameters,
and communicate with network device consoles and touchpanels, among
many other tasks. Viewport can also function as a terminal emulator for
generic file transfer. All of these functions are accessed through the
commands and options in the Viewport menus. Therefore, for its
effectiveness as a support and diagnostic tool, the Crestron Viewport may
be preferred over development tools when uploading programs and
projects.
The following sections define how one would upgrade the firmware of the
C2N-RTHS. However, before attempting to upload or upgrade, it is
necessary to establish communications.
Communication Settings
NOTE: For laptops and other PCs without a built-in RS-232 port,
Crestron recommends the use of PCMCIA cards, rather than USB-to-
serial adapters. If a USB-to-serial adapter must be used, Crestron has
tested the following devices with good results:
Belkin (large model) F5U103
I/O Gear GUC232A (discontinued)
Keyspan USA-19QW (discontinued)
NOTE: Results may vary depending on the computer being used. Other
models, even from the same manufacturer, may not yield the same results.
The procedure in this section provides details for RS-232 communication
between the PC and the control system. If TCP/IP communication is
preferred, consult the latest version of the Crestron e-Control Reference
Guide (Doc. 6052) or the respective Operations Guide for the control
system. These documents are available from the Crestron website. Refer
to the figure on the next page for a typical connection diagram when
uploading files.
