Product Information
AXB-MPE+ Dual and Single Master Port Expanders
The AXB-MPE+ Dual and Single Master Port Expanders (FIG. 1) are AXCESS Control Systems
that are equipped with 12 AXlink ports that can control multiple audiovisual and lighting device up
to 3,000 feet from the control system. With the AXCESS programming software, you program the
AXC-EM cards, housed in the AXB-MPE+, to control the devices. The AXB-MPE+ Dual Master
Port Expander comes with two AXC-EM cards: the first card is the main processor and the second
is the stand-by processor. If a problem occurs with the first card, the AXB-MPE+ automatically
switches to the second card without disrupting service.

AXB-MPE+ Master Port Expander and AXB-SPE Slave Port Expander
Installation and Configuration
Before you install the AXB-MPE+, you should check the AXC-EM Master Card DIP switch for
correct settings, and also set the PROGRAM RS-232 DIP switch on the front panel of the AXB-
MPE+. FIG. 1 shows the orientation of the AXC-EM components discussed in this section.
AXC-EM Master Card DIP Switch Settings
All the AXC-EM Master Card DIP switch positions must be set OFF to communicate with the
AXB-MPE+.
To verify the AXC-EM Master Card DIP switch is set correctly:
1. Discharge the static electricity from your body by touching a grounded object.
2. Remove the two Phillips-head screws from the top panel on the AXB-MPE+, and slide the
panel backward to access the AXC-EM Master Cards. FIG. 1 shows the DIP switch location on
the AXC-EM card.
3. Set all the DIP switch positions OFF (down), as shown in FIG. 2. If the AXB-MPE+ is
equipped with two AXC-EM Master Cards, repeat this step on the second card.
4. Close the top panel, insert the Phillips-head screws, and tighten.

AXB-MPE+ Master Port Expander and AXB-SPE Slave Port Expander
Configuring the MPE+ to use One or Two AXC-EM Cards
The AXB-MPE+ Master Port Expander uses one AXC-EM master card. The AXB-MPE+ Dual
Master Port Expander uses two AXC-EM master cards. Both come factory set to either a single or
dual expander. If you are using an AXC-MPE+ Master Port Expander and want to upgrade the unit
to use two AXC-EMs:
1. Discharge the static electricity from your body by touching a grounded object.
2. Remove the two Phillips-head screws from the top panel on the AXB-MPE+, and slide the
panel backward to access the AXC-EM Master Cards (FIG. 3).
3. Locate the Jumper location (JP1A and JP1B) between the AXC-EM internal connection ports.
4. To set the Port Expander to use one master, place the jumper from JP1A on pins 1 and 2
(SINGLE) and verify that the jumper from JP1B is also on pins 1 and 2. This setting allows the
user to program the single AXC-EM card using either the front or rear Program ports. Refer to
the Programming the AXB-MPE+ (One AXC-EM Card) section on page 11 for more
information.
5. To set the Port Expander to use two master, place the jumper from JP1A on pins 2 and 3
(DUAL) and verify that the jumper from JP1B is also on pins 2 and 3. Refer to the
Programming the AXB-MPE+ Dual Master Port Expander (Two AXC-EM Cards) section on
page 12 for more information.
This setting allows the user to ONLY program:
! AXC-EM Card #1 (see FIG. 3) using the front Program port on the MPE+ and
! AXC-EM Card #2 (see FIG. 3) using the rear Program port on the MPE+.

Installation and Configuration
8AXB-MPE+ Master Port Expander and AXB-SPE Slave Port Expander
Wiring the AXB-MPE+ and AXB-SPE
You must connect a 12 VDC power supply to the AXB-MPE+ and AXB-SPE to control external
equipment. If you connect external AMX equipment, refer to the associated AMX manuals for
wiring and power supply information. This section describes how to wire a control system.
Guidelines
The AXB-MPE+ and AXB-SPE requires 12 VDC power to operate properly. The maximum wiring
distance between the control equipment and external equipment is determined by power
consumption, supplied voltage, and the wire gauge used for the cable. The maximum wiring
lengths for using AXlink power are based on a minimum of 13.5 volts available at the
AXB-MPE+'s and AXB-SPE's power supply.
Preparing captive wires
You will need a wire stripper, soldering iron, and flat-head screwdriver to prepare and connect the
captive wires.
1. Strip 0.25 inch of wire insulation off all wires and apply a light coat of solder to the ends using
a soldering iron.
2. Insert each wire into the appropriate opening on the connector according to the wiring
diagrams and connector types described in this section.
3. Turn the flat-head screws clockwise to secure the wire in the connector.
Using AXlink for data and a 12 VDC power supply
Connect the AXB-MPE+ and AXB-SPE AXlink connector to the AXlink connector on the external
equipment, and the 12 VDC power supply as shown in FIG. 4.
Do not over-torque the screw. Doing so can bend the seating pin and damage the
connector.

Connecting an AXB-MPE+ to the AXB-SPE
FIG. 5 shows how to connect the expansion cables between the AXB-MPE+ and AXB-SPE. AMX
supplies the RJ-11 module cable with the AXB-SPE.
Replacing the Lithium Batteries
There are two lithium batteries (see FIG. 1 on page 5), with a life of approximately 5 years, on the
AXC-EM Master Card that protects stored commands if there is a power loss. The batteries are not
used when DC power is supplied to the cards via the AXB-MPE+. You should write down the
replacement date on a sticker or label by adding 5 years to the date of installation, and then attach it
to the back of the AXB-MPE+
Before you replace the lithium batteries, verify that your AMX dealer has a current copy of control
commands stored in your AXB-MPE+. This will avoid any inadvertent loss of data or a service
outage.
You will need a flat-blade tool (non-conducting) that can be slipped under the lithium batteries to
pry them up and out of the sockets:
1. Discharge the static electricity from your body by touching a grounded object.
2. Disconnect all the connectors from the back panel on the AXB-MPE+. Then, remove it from
the equipment rack (if applicable), and lay it down on a non-conductive surface.
3. Remove the two Phillips-head screws from the top panel on the AXB-MPE+, and slide the
panel backward to access the lithium batteries on the AXC-EM Master Cards.
4. Carefully pry one battery out of its socket and insert the new battery.
5. Plug the power supply back into the AXB-MPE+ for approximately 1 minute. Then,
disconnect the power supply again.
6. Carefully slide the other battery out of its socket, and insert the new battery.

PROGRAM
Static electricity can damage electronic circuitry. Before removing the lithium
batteries from the card, discharge any accumulated static electricity from your body
and screw-driver by touching a grounded metal object.
There is a danger of explosion if you replace the battery incorrectly. Replace the
battery with the same or equivalent type recommended by the manufacturer. Dispose
of used battery according to the manufacturer's instructions. Never recharge,
disassemble, or heat the battery above 212 °F (100 °C). Never solder directly to the
battery or expose the contents of the battery to water.

256 KB Firmware Upgrade
Firmware upgrades allow you to maintain the latest available operating system for your AXB-
MPE+. This section describes how to remove and replace the firmware EPROMs on the AXC-EM
Master Cards in the AXB-MPE+. You will need a Phillips screwdriver and a non-conducting flat-
blade tool to slip under the firmware ICs to lift them out of their sockets. FIG. 1 on page 5 shows
where the firmware EPROMs are located on the AXC-EM cards.
1. Discharge the static electricity from your body by touching a grounded object.
2. Disconnect all the connectors from the back panel on the AXB-MPE+. Then, remove it from
the equipment rack (if applicable), and lay it down on a non-conductive surface.
3. Remove the two Phillips-head screws from the top panel on the AXB-MPE+, and slide the
panel backward to access the AXC-EM Master Cards.
4. Carefully pry the firmware EPROMs out of their sockets labeled U3 and U4 on card 1 and card
2 (if applicable) with a non-conducting flat-blade tool, and install the new firmware EPROMs
as shown in FIG. 6.
5. Close the top panel, insert the Phillips-head screws, and tighten.
6. Return the AXB-EM+ to the equipment rack and reconnect all the connectors removed in
