TXC+ Transmitter Series
Product Information
Through the use of infrared (IR) or radio frequency (RF) transmission mediums, the TXC+ hand-
held wireless transmitters control a wide variety of devices connected to an AMX Axcess Control
System. These transmitters include the TXC4+, TXC4L+, TXC16+, and TXC32+. For these units
IR, signals are transmitted at 38 kHz or 455 kHz and RF signals at 418 MHz.
The TXC4+ is a four-pushbutton transmitter (FIG. 1) and the TXC16+ transmitter is a 16-
pushbutton configuration (FIG. 2).
Each pushbutton performs a specific operation according to the Axcess software program in your
AMX Control System. The red transmission LED, located in the top-center of the TXC16+ and
TXC32+ transmitters, flashes when you press one of the pushbuttons, indicating that an RF or IR
signal is being transmitted.
The TXC32+ (FIG. 3) provides up to 48 programmable pushbuttons. The number of pushbuttons
varies depending on the overall system design.

Battery Replacement
TXC4+ and TXC4+L batteries
The TXC4+ line of hand-held wireless transmitters have identical battery placement areas. Remove
the access cover on the back of the transmitter and replace the two AAA batteries. Under normal
conditions, battery life will exceed 1 year. Use alkaline batteries for long battery life and optimum
performance.
TXC16+ batteries
Remove the access cover on the back of the TXC16+ transmitter and replace the two 1.5-volt, "N"
size batteries. Under normal conditions, battery life will exceed 2 years. Use alkaline batteries for
long battery life and optimum performance.
TXC32+ batteries
Remove the access cover on the back of the TXC32+ transmitter and replace the four 1.5-volt, "N"
size batteries. Under normal conditions, battery life will exceed 2 years. Use alkaline batteries for
long battery life and optimum performance.
OLDesign Overlay Engraving Design Software Program
The AMX OLDesign software program is a Windows™-based design tool that you use to create
panel overlays, pushbutton names, and pushbutton operation descriptions. The operation
descriptions are used when the Axcess operating software is programmed. OLDesign also contains
an online help system that describes how to produce custom overlay designs and pushbutton
descriptions, and then store them on your computer. FIG. 4 shows the OLDesign main window and
a sample TXC32+overlay design. Refer to the OLDesign Overlay Design Program instruction
manual for command instructions that can be used with the OLDesign online help system.

IR, IR Frequency, RF, and Radio Code Settings

TXC+ Transmitter Series
IR, IR Frequency, RF, and Radio Code
Settings
The TXC+ series transmitters transmit IR or RF signals, according to how you set positions 1, 2,
and 3 on the 10-position DIP switch (FIG. 5) located under the battery cover.
IR, IR Frequency, and RF Settings
FIG. 5 shows the DIP switch settings for IR and RF modes. The transmitter can only be configured
for either IR of RF, not both.
Radio Code
Each pushbutton on your transmitter represents an Axcess channel number. All of the pushbuttons
on a transmitter represent a group of channel numbers. This grouping is known as a radio code.
After the radio code is set on the transmitter, each button you press sends a specific channel number
to the control system. For example, if your TXC+ transmitter is set to radio code 4 and you press
button 1, channel number 64 is sent to the control system.
Setting radio codes
The table below lists the radio codes, DIP switch positions, and ranges for the TXC4+.
The formula to determine the channel number of a TXC4+ series transmitter is:
(Radio code offset) + (Radio code number multiplied by 16).
Radio Code Offset corresponds to the number of buttons available on the transmitter. Each button
containing its own push-channel.
Refer to the TXC4+ Series Radio Code Offsets and Shifts table on page 7 for the TXC4+ series
radio code offsets a shift.

TXC+ Transmitter Series
The table below lists the radio codes, DIP switch settings, and ranges for the TXC16+ and TXC32+
transmitters.
Trigger switch operation (TXC4+ series only)
The TXC4+ series transmitters have a trigger switch on the front underside of the transmitter (see
FIG. 1 on page 1). On the TXC4L+ model, this switch operates the laser pointer. On the TXC4+
model, this switch can be configured in one of two ways:
! Configuration 1 (default): Pushbutton 1 Remove the battery cover and locate position
4 of the DIP switch. If position 4 is in the OFF position, the trigger switch functions
exactly like the pushbutton 1 on the topside of the transmitter. To set position 4, move the
switch up (ON) or down (OFF).
!
Configuration 2: Radio code offset shift Remove the battery cover and locate position 4
of the DIP switch. Refer to the TXC4+ Series Radio Code Offsets and Shifts table if
position 4 is in the ON position, the trigger switch shifts up the radio code offset by 8

Radiation hazards
Laser beams produce light frequencies that are harmful to the human eye. DO NOT look into, or
shine a laser beam into another person's eyes. Laser light frequencies can cause retina damage.
Read the following WARNING.
FIG. 6 Laser radiation hazard

Troubleshooting
9
TXC+ Transmitter Series
Troubleshooting
Read through the troubleshooting information below if you are experiencing a problem with your
transmitter. If the problem cannot be resolved, call your AMX dealer.
If the red LED does not flash:
1. Remove the transmitter's battery cover and verify that the batteries are correctly installed.
2. Verify that the batteries are fully charged using a voltage tester. If not, replace the batteries.
3. If the transmission LED does not flash and one of the following conditions is true, return the
unit to your AMX dealer for repair:
! RF system receiver responds correctly when you press a transmitter pushbutton.
! IR receiver LED lights when you press a transmitter pushbutton.
If the red LED flashes but the AMX system does not respond:
1. Verify that positions 1, 2, and 3 of the DIP switch are set to the correct transmit mode.
2. When using RF mode, verify that position 3 of the DIP switch if ON (up).
3. Verify channel code transmission range (FIG. 5 on page 5) matches the receiving control
system's program.
4. Hold the transmitter closer to the IR or RF receiver. If the problem stops, the transmitter
signals cannot reach the control system due to high levels of IR or RF interference or weak
transmitter batteries.
! IR interference is typically generated by lights. Try turning off room lights to check for
improved performance.
! RF interference may be caused by electronic devices such as computers, motors, lighting
ballasts, wireless microphones, etc. Move or reset the receiver's position.
