The CNRFHT, illustrated in figure 1, is a hand-held radio-frequency (RF) transmitter. The unit is designed to operate
with the CRESNET II remote control system (herein referred to as the CRESNET II system) via a RF wireless
receiver, CNRFGW Wireless Gateway. The CNRFHT is available with 15 or 30 button controls. Depression of any
button on the CNRFHT customized 15- or 30-button panel initiates a RF signal transmission to the CNRFGW.
CNIRHT-15/30:
The CNIRHT, illustrated in figure 1, is a hand-held infrared (IR) transmitter. The unit is designed to operate with the
CRESNET II system via an IR wireless receiver, CNIRGW Wireless Gateway. The CNIRHT is available with 15 or
30 button controls. Depression of any button on the CNIRHT customized 15- or 30-button panel initiates an IR
signal transmission to the CNIRGW.
Sleep Mode:
CNRFHT and CNIRHT have a power-saving mode, known as sleep mode, to extend battery life. If the unit remains
inactive (no buttons are depressed) for approximately six hours, the unit enters a default setting, sleep mode.
Actual inactivity duration to initiate sleep mode may vary. To reactivate the unit from sleep mode, depress and hold
a button on the unit until it begins transmitting. Transmission is indicated by the illumination of a red LED located
above the button panel cover.
Physical Description
NOTE
CRESTRON does not recommend designing large button caps for single functions. Depressing
the center of a large button cap can cause the unit to transmit incorrectly which may result in
the control system misinterpreting the user's intent. Therefore, design large button caps for
dual functions, such as a volume up/volume down rocker-type button.
CNRFHT and CNIRHT electronic hardware is housed in a slim, high-impact molded ABS black plastic enclosure
(refer to figure 2). A 30-button array on the printed circuit board is covered by a customized button panel. All
button panels include custom engraving, colored button caps, choice of button configurations, and panel finishes.
Small and large button caps are available. A small button cap covers one button. A large button cap covers two
buttons. Refer to the latest version of the CRESNET II Engraving Worksheet for CNRFHT and CNIRHT (Doc. 5344)
to design a unique button panel. Omission of unused buttons is standard. A red LED is located above the button
panel cover.

Aside from the diversity in button panel configuration, the only external difference between CNRFHT and CNIRHT is
the type of plastic material at the pointing end of each unit. CNRFHT has a black plastic cover with a tuning hole
(refer to figure 1) and CNIRHT has a ruby-colored IR signal filter.
A nine-volt battery is included with all units. Access to the battery is permitted after the battery cover, located on
the underside of the unit, is removed.
Configuration Differences
The CNRFHT and CNIRHT each have two different configurations which are depicted in table 1.

CONTROLS AND INDICATORS:
Controls
Button controls are custom designed. CNRFHT and CNIRHT are available with 15 to 30 functional buttons.
Function definition is determined by application of the unit within the CRESNET II system. The customized button
controls correspond to signal names that are defined in the SIMPL program.
A tuning hole is located on the pointing end of the CNRFHT. This control mechanism permits the user to adjust the
frequency. Refer to Installation/Setup for tuning techniques.
Indicators
There is only one indicator located on the CNRFHT and CNIRHT. The indicator is a red LED and resides on the face of
the unit above the button panel cover. The LED indicates IR/RF transmission and illuminates when a button is
depressed.

Every hand-held wireless transmitter communicating with either the CNRFGW or CNIRGW requires a unique
identity code (ID CODE). For RF devices the ID CODE is referred to as RF ID. For IR devices the ID CODE is referred
to as IR ID. There are 256 possible two-digit hexadecimal alphanumeric codes ranging from 00 to FF. To maintain
code diversity within the CRESNET II system, use codes between 10 and FE for the transmitters.
NOTES
1.The ID CODE on the CNRFHT and CNIRHT is factory set to 20.
2.Do not use 00 or FF as an RF/IR ID.
3.Do not confuse RF/IR ID with network (NET) ID.
To set an ID CODE complete the following steps.
1.Position the unit button-side down so the battery compartment is accessible.
2.Remove the battery cover.
3.Remove four screws from the unit (two screws are located within the battery compartment).
4.Gently lift the rear cover off the unit.
5.Refer to figure 3 and locate an eight-position SIP switch on the printed circuit board. Switches labeled 1
Rear Cover and

through 4 represent the least-significant digit or letter of the ID CODE. Switches labeled 5 through 8
represent the most-significant digit or letter of the ID CODE.
6.Refer to table 3 and translate the ID CODE two-digit hexadecimal number or letter into an eight-digit SIP
switch code.
NOTES
1.The ID CODE of the unit is factory set to 20. This hexadecimal setting corresponds to an
eight-digit SIP switch code of 00000100, with respect to SIP switches 1 through 8.
2.A "1" in the table indicates that the switch should be set in the direction of the arrow
head located on the SIP switch. A "0" in the table above indicates that the switch should be
set in the opposite direction of the arrow head.
The following installation instructions are for the CNRFHT only.
The CNRFHT and CNRFGW are factory tuned and normally do not require tuning. However, in some cases it may be
necessary to tune the CNRFHT transmitter for the CNRFGW to receive signals properly. Complete the following
steps to tune the transmitter and receiver.
RF Receiver
1.Verify CNRFGW power is on. The green LED marked NET PWR on the receiver illuminates when power is on.
2.Position the CNRFGW on its side so that the silk-screened face is visible.
3. To optimize reception extend the CNRFGW antenna vertically to a height of nine to 10 inches.
CAUTION
Do not force the tuning adjustment on the receiver. Over exerting the tuning adjustment may
damage the unit.
4.Use a nylon (non-conductive) tuning tool and gently turn the tuning adjustment on the face of the CNRFGW
clockwise, until it comes to a stop.
5.Hold the tuning tool firmly; gently turn the tuning adjustment counterclockwise, two complete turns. This sets
the receiver frequency to 300 MHz, which is the factory standard setting. Frequencies ranging between 270
and 330 MHz can be used by turning the tuning adjustment to different positions.
RF Transmitter
CAUTION
Do not force the tuning adjustment on the transmitter. Over exerting the tuning adjustment
may damage the unit.
1.Place the tuning tool into the tuning hole located at the pointing end of the CNRFHT; gently turn the tuning
adjustment clockwise until it comes to a stop.
2.With CNRFHT in hand, stand approximately six feet from the CNRFGW.
3.Insert the tuning tool into the CNRFHT; gently turn the tuning adjustment counterclockwise, approximately
two full turns.
4.Aim the CNRFHT at the CNRFGW antenna; depress any button on the transmitter.
5.While aiming and depressing any button, gently turn the tuning tool in either direction, until the red LED marked
SIGNAL on the CNRFGW illuminates.
6.Once the frequency is located, it may be necessary to fine tune the device by slowly turning the tuning tool in
either direction, until the red LED marked SIGNAL is brightly illuminating. The LED must be at its brightest
setting to confirm the unit is tuned to the highest lobe of the frequency range.
7.Move to a different location within the room; depress any button on the transmitter to verify proper frequency
setting.
NOTE
The red LED on the CNRFGW will not illuminate when it is approximately 10 to 15 feet from the
CNRFHT. The system is still functioning, but the threshold to illuminate the signal is too low.
However, the red LED on the CNRFHT illuminates when a button is depressed, indicating the
remote is transmitting.
8.If "dead" spots are found within the room, insert the tuning tool into the CNRFHT and carefully make further
adjustments in either direction to fine tune the system.
PROGRAMMING:
A 30-button array is located beneath the custom button panel of each CNRFHT and CNIRHT. Refer to figure 4 for an
illustrative layout of transmitter button numbers beneath a sample button panel. The numbering for each button is
constant. For each button input, a signal name must be defined in the SIMPL program. Unused buttons need not be
assigned signal names. An example following figure 4 illustrates button definition in the CRESNET II Workshop.
Access the following tables from the "Define Network" section of the SIMPL-I Menu. An example of SIMPL-C
programming for the same custom button panel design is shown in the Appendix.
