AXU-MSP Series and AXM-MSP32 Introduction 1
Introduction
Overview
The AMX UniMount Mini-SoftWire Panels (AXU-MSP) are microprocessor-
controlled pushbutton display units that can be programmed to control a wide
variety of equipment connected to an AXCESS system. The AXU-MSP series include
the AXU-MSP8, AXU-MSP16, AXU-MSP24, AXU-MSP32. The AXM-MSP32, which
contains the same pushbutton and bargraph configuration as the AXU-MSP32, can
be mounted into a 19-inch rack. This guide contains front and rear panel illustration
examples, programming instructions, installation procedures, panel specifications,
OLDesign overview, and technical support information. Figure 1shows a sample
AXU-MSP8 panel.

2Introduction AXU-MSP Series and AXM-MSP32
Features
Each panel connects to an AMX AXCESS control system using an AXlink cable. The
panel pushbuttons perform specific operations according to the AXCESS software
and cards in your control system. Each panel comes with a custom engraved overlay
and pushbutton configuration to optimize usability. The number of pushbuttons can
vary depending on the number of operations the panel must perform. Panel features
include the following.
Features include:
• Compatible with all AXCESS control systems.
• Wide range control of multimedia presentation equipment.
• Custom engraved panels.
• Custom pushbutton functions and groupings.
• Custom LED bargraph applications.
• Installs into most standard wall box enclosures.
Front Panels
Mini-SoftWire Panel (MSP) pushbuttons can be programmed individually or in any
combination as a single device or as a group. The bargraph LEDs can also be
programmed individually or as a group. The LEDs can be used in conjunction with
any one of the pushbuttons or as an independent display indicator. Figure 2shows
the AXU-MSP16, Figure 3shows the AXU-MSP24, Figure 4shows the AXU-MSP32,
and Figure 5shows the AXM-MSP32.

AXU-MSP Series and AXM-MSP32 AXCESS Programming 5
AXCESS Programming
Overview
MSP pushbuttons can be programmed individually or in any combination as single
devices or in a group arrangement. Bargraph LEDs can be programmed to interact
with panel pushbuttons. They can be programmed to work with any one of the
pushbuttons, or as independent display indicators.
Push Displays
The AXCESS software program will display the following when you press one of the
pushbuttons on your panel.
PUSH [panel device number, button number]
The pushbutton response appears in the AXCESS software program's PUSH
window. You can press the ALT and F keys on your keyboard to see what the
pushbutton does in the software program. You can also press the ALT and I keys to
insert the pushbutton in the software program and enter the pushbutton's function.
Pushbutton LEDs
Each LED in the panel's pushbuttons are assigned with feedback assignments. The
following is an example.
[Panel device number, button number of LED] = [RELAY, 1]
The LED will follow the status of device RELAY, channel, or relay number 1.
Note
Refer to the AXCESS
Language Programming
Manual for complete
programming information.

6AXCESS Programming AXU-MSP Series and AXM-MSP32
Bargraph Programming
To program LED bargraphs, commands similar to those in the following example
are included in the AXCESS software program.
DEFINE_DEVICE
VOL = 12 (* VOLUME CONTROL CARD DEVICE 12 *)
MSP = 128 (* MINI SOFTWIRE PANEL DEVICE 128 *)
DEFINE_VARIABLE
MIC_LEVEL (* VARIABLE TO HOLD CURRENT MIC *)
(* VOLUME LEVEL *)
DEFINE_START
CREATE_LEVEL VOL,2,MIC_LEVEL (* MIC_LEVEL HAS THE CURRENT LEVEL *) (* OF
CHANNEL 2 OF THE VOLUME CARD *)
DEFINE_PROGRAM
SEND_LEVEL MSP,1,MIC_LEVEL (* MIC VOLUME DISPLAYS ON FIRST BAR *)
(* GRAPH. THIS STATEMENT CAN BE *)
(* ANYWHERE IN THE PROGRAM. *)
Bargraph Modes
You can program panels using three bargraph modes; bar mode, dot mode, and
discrete mode. Bar mode (system default) will activate LEDs in a bottom-to-top
sequence. Dot mode will only activate the peak LED of the display level. Discrete
mode can be set to activate any combination of LEDs. Figure 8shows a sample
bargraph mode.

AXU-MSP Series and AXM-MSP32 Installation 9
Installation
Overview
This section describes how to install the MSP.
Wall, Podium, and Rack Mounting Procedures
Install the wall, podium, or rack-mount MSP as follows:
1. Cut out the wall or podium according to the mounting dimensions provided in
the Specifications section of this guide. Go to step 2 if the panel will be installed
into a wall box or rack.
2. Locate and set the SIP switch on the rear side of the panel according to the SIP
switch values below. The device number is set by the total value of SIP switch
positions that are ON (down). The AXCESS software programs in your system
typically use device numbers 128 through 255 for the panels. Figure 11 shows a
SIP switch example set to device number 129 (1+128=129), and the values for
each SIP switch position.
1 2 3 4 5 6 7 8
ON
Switch 12345678
ON Value 1 2 4 8 16 32 64 128
3. Locate and connect the AXlink data and power bus to the panel as follows.
a. Strip .25 inch of insulation off each wire, and tin the ends with solder.
b. Insert each wire into the appropriate opening on the connector according to
the AXlink wiring diagram shown in Figure 12.

c. Turn the captive screws clockwise to secure the wires.
d. Connect the AXlink connector to the panel.
4. Locate the green AXlink LED on the rear side of the panel. If the green LED
flashes once per second, the panel is communicating properly with the AXCESS
system. If the LED is on and not flashing, disconnect the AXlink connector and
recheck all AXlink connections. Afterwards, reconnect the AXlink connector to
the panel and verify the LED is flashing once per second.
5. Locate the slot on the front panel and gently remove the overlay from the
faceplate.
6. Place the panel in the wall, wall box, podium, or rack, and align the screw holes
with the mounting holes on the panel.
7. Fasten the panel to the wall, wall box, podium, or rack using the screws
supplied with the panel.
8. Put the engraved overlay back on the panel's bezel or rack mount faceplate.
Caution
Do not over-torque the screws
on the wires. Doing so can
bend the seating pins and
damage the connector.

AXU-MSP Series and AXM-MSP32 OLDesign Software Program 11
OLDesign Software Program
Overview
This section gives an overview of the tool to use to program the MSP.
Features
The AMX OLDesign software program is a Windows-based design tool that you can
use to create panel overlays, pushbutton names, and pushbutton operation
descriptions. The operation descriptions are used when the panel and AXCESS
operating software is programmed. OLDesign also contains an on-line help system
that provides operating instructions you can use to produce custom overlay designs
and pushbutton descriptions, and then store them on your computer. Figure 13
shows the OLDesign main window, and Figure 14 shows a sample AXU-MSP8
overlay design. Refer to the OLDesign for Windows Quick Reference Guide for
command instructions that can be used in conjunction with the OLDesign's on-line
help system.
