H-ITT RX4000 instruction manual
H-ITT 420 Shearer Blvd Cocoa, Florida 32922
GENERAL:
The RX4000 communicates with all H-ITT RF clickers. There is no limit to the number of RF clickers that can be used with the RX4000.
The RX4000 has 31 RF channels that can be selected and are provided so that a classroom may have a unique RF channel to avoid
interference between another device in or about the classroom. The RX4000 is initially set to channel 07 to operate with H-ITT RF
clickers that are also initially set to channel 07. The RX4000 has selectable baud rates for communication to your PC. The default
setting is 19.2K baud. Higher Baud rates are available, but typically not needed. If higher baud rates are selected, the length of the USB
cable should not exceed 15 feet. There can be more than one RX4000 installed in a very large classroom or auditorium to provide
reliable communication with H-ITT’s remote clickers.
INITIAL SET-UP:
The RX4000 provides both USB and Serial communications ports.
Connect either of these ports to your classroom PC (do not connect both).
The
USB connection
provides power to the unit, so this is the only
connection needed. You will need to install a driver for the USB port in
your PC to communicate with H-ITT software (see below for connecting to
a computer). However, the RX4000 will power up as indicated below with
or without the drivers installed.
Attach the antenna to the SMA connector.
Power up the RX4000 by connecting the USB cable to a PC (that is
powered up) or connect the external power supply to the DC power jack.
The YELLOW indicator light will turn on and both the GREEN PC com and
RED RF com indicators will blink 4 times each. If the RF com indicator
blinks more than 4 times, and at a rapid rate, this can indicate that the RF
channel selected may have another fixed frequency transmitter operating on the same channel within the range of the base. If this
occurs, it is recommended that a different channel be selected using the internal set-up switch described below.
Connecting the RX4000 to your computer:
You can connect the RX4000 to your computer using the USB cable (which also provides power to the RX4000) or through a serial
connection (which requires an external power supply). The most common is the USB connection with the cable provided. Depending on
your operating system (Windows, Mac or Linux) you may need to install USB drivers for the software to properly handle the
communications from the RX4000 to your computer. USB drivers vary depending on your computers operating system; Windows or
Mac (Linux drivers are built in). Windows and Mac USB drivers are included on the CD supplied with the RX4000, click the link to
download/install the appropriate USB driver for your operating system. USB drivers are also provided at H-ITT.COM from the download
links where you will find instructions based on your operating system.
Installing Windows USB drivers
may be confusing because when the RX4000 is first connected a “found new hardware” wizard will
pop-up. If you are connected to the Internet, this wizard can locate and install the proper drivers, but if not connected to the net the
wizard will return “drivers not found”. To simplify this, we recommend that you download the Windows USB driver “auto installer” to your
computer (either from the CD or from H-ITT.COM) and install drivers by double clicking the “auto installer”.exe file.
If the
Serial port
is used, the unit must have an external power supply connected, use H-ITT part number # AC-9VDC-US for standard
North American power outlets or AC-9VDC-INT for international power outlets.
TEST
With the RX4000 powered up,
the RX4000 using a H-ITT RF remote (TX3000 or TX3100)
by pressing a button (A/1 through J/0)
on an RF clicker and notice the GREEN PC Com light and RED RF com lights blink. This indicates the RX4000 is ready to operate.
Test with H-ITT software
to make sure USB drivers are installed and the RX4000 is communicating with your computer:
Open H-ITT-CRS Acquisition program. On the initial screen of the Acquisition program under “Base Units and Port Settings” you will
see a new COM port appear when the base unit is connected with a USB cable. When a remote is activated, the remotes serial number
will appear under the Detected Responses columns.
Test the RX4000 installation:
To ensure reliable communication between the RX4000 and remotes, go to the far corners of the
room (or from worst case seat positions) and verify the remotes green light turns on with a key press, and The RED and GREEN lights
on the RX4000 blink with each key press.
In most applications your H-ITT system is now ready to operate using the default settings, so once you verify that the RX4000 powers
up , and communicates with software, it is ready to use.
The following options of the RX4000 can be used if the application requires, but typically is not necessary.

Serial Port
DC power jack
