Introduction
Overview
The TXC4, TXC32+, and TXC16+ line of hand-held wireless transmitters control a
wide variety of devices, using infrared (IR) or radio frequency (RF) transmission
medium, connected to an AMX AXCESS Control System. They can transmit IR
signals at 38 kHz or 455 kHz and RF signals at 303.875 MHz.
The TXC4 is a four pushbutton transmitter (Figure 1) while the TXC16+ transmitter
is available in a 16-pushbutton configuration, as shown in Figure 2.

The TXC32+ can have up to 48 pushbuttons, as shown in Figure 3. (Figure 3is
shown fully populated to identify button numbers.) The number of pushbuttons
varies depending on the overall system design.

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 transmitter, flashes when you press one of the pushbuttons,
indicating that an RF or IR signal is being transmitted.

Features
The TXC transmitters offer these features:
• RF and IR wireless control
• Selectable 38 kHz or 455 kHz IR frequency
• Custom pushbutton configurations
• Microprocessor-based architecture
• Custom-engraved overlay and pushbutton layouts
• Alternate radio frequencies
• LED to indicate signal transmission (TXC16+ and TXC32+ only)

OLDesign
OLDesign is an optional Windows-based tool that aids design of transmitter overlay,
designs, button names, and button operation descriptions. The operation
descriptions are used when the transmitter and AXCESS operating software are
programmed. OLDesign also contains an online help system that provides operating
instructions to produce custom overlay designs and button descriptions, and then
stores them on your computer.
Refer to the OLDesign for Windows Quick Reference Guide for command instructions
that can be used with the OLDesign’s online help system.

Frequency Settings
Overview
The TXC series transmitters transmit IR or RF signals, depending on how you set
positions 1, 2, and 3 on the 10-position DIP switch (Figure 4) located under the
battery cover. You must set the DIP switch position 3 to ON for RF mode.

Radio Code
Each pushbutton on your transmitter represents an AXCESS channel number. All of
the pushbuttons on a transmitter represents 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 TXC16+ transmitter is set to radio code 4 and you press button 1,
channel number 64 is sent to the control system (Figure 7).

Set the transmitter’s radio code using DIP switch positions 7 through 10, which are
accessible when the battery cover is removed.
The formula to determine the channel number of the TXC16+ and TXC32+ is (button
number - 1) + (radio code number multiplied by 16).
The formula to determine the channel number of a TXC4 series transmitter is (radio
code offset) + (radio code number multiplied by 16). Refer to Figure 9 for the TXC4
series radio code offsets.

Trigger switch operation (TXC4 series only)
The TXC4 series transmitters have a trigger switch on the front underside of the unit.
On the TXC4L and TXC4L+ models, this switch operates the laser pointer. On the
TXC4 and TXC4+ models, this switch can be configured in one of two ways:
Configuration 1 (default): Pushbutton 1
Remove the battery cover and locate position 4 (Figure 6) 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. If position 4 is in
the ON position, the trigger switch shifts up the radio code offset by 8 (e.g.: add 8 to
the radio code offset value to calculate the channel number being transmitted (see
Figure 9). To set position 4, move the switch up (ON) or down (OFF).

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. The frequencies of laser
light can cause eye retina damage. Read the following WARNING .
