AXP-CPI Custom Panel Interface Introduction 1
Introduction
Overview
The AMX AXP–CPI Custom Panel Interface is used in combination with the AMX
AXCESS card system as an interface to custom control panels. Contact closures
sensed by the AXCESS system are converted into signals to turn on the control
panel lamps. A 64-pin panel connector and cable provides connections for up to 64
contacts and visual indicators such as incandescent lamps and LEDs. A mini-jack
provides connections for LED bargraph programming and control.
Front Panel
Figure 1shows the front panel of the AXP–CPI that includes a 64-pin panel
connector for the ribbon cable interface connector, and 2-pin connector for lamp
power.

Front panel connectors
Front panel connectors include:
•64-pin Ribbon Cable Connector — connections for up to 64 lamps and
contact sensors. A 64-wire ribbon cable (included) is used to make
connections to your custom control panel. Maximum cable length, from your
panel (switches and lamps) to the CPI is 30 feet.

2Introduction AXP-CPI Custom Panel Interface
•2-pin Captive-wire Connector — contact common and lamp power
connections. Maximum voltage is 48 VDC and maximum current at any
voltage is 2.0 Amps. Suggested lamp voltages are 5–28 VDC. The right-most
terminal is the voltage plus and is designated Pin 2. Pin 1 is the lamp minus
voltage and the contact common connection.
•3-wire Mini–jack — signal, 5 VDC, and ground for bargraph control in
each of 5 modes – 0, 1, 2, 3, and 8. The LED bargraphs are equivalent to the
standard SoftWire panel bargraphs.
Back Panel
Signal, control, and power connections are made on the back panel of the AXP–
CPI. Included are AUX Power, AXlink plus (AXP) and minus (AXM) signals, the
AXlink active LED indicator, the lamp glow level adjustment, and the input
connector for lamp power. The system device code switches are also located on the
back panel as shown in Figure 2.

•Aux Power — 12 VDC power supplied to the AXP–CPI from a standard
AMX power module using a 2-pin captive-wire connector. You do not need to
use Aux Power when power is supplied from the AXlink connector.
•AXlink — the AXCESS system bus connections and 12 VDC power to the
AXP–CPI using a 4-pin captive-wire connector.

AXP-CPI Custom Panel Interface Introduction 3
•Device Number — an identification number used by the AXCESS system.
The 8-position SIP switch (Figure 3) defines the AXP-CPI as an AXlink
device. They can be one of 255 devices in the AXCESS Control System. Set the
device number with the total value of all ON (down) positions. As an
example, the SIP switch below defines device number 129 (1+128=129).

If you change the device number, remove and reconnect the AXlink
connector to reset the new device number in memory.
•AXlink (lamp) — an LED used to indicate activity of the AXlink bus
connected to the AXCESS system.
•Glow Level — adjusts the lamps to a minimum brightness. Provides a back-
lighted effect to the display lamps.
•Lamp Power — external power supplied to the lamps connected to the
control panel. A 2-pin captive-wire connector is used to make the power
connection.

AXP-CPI Custom Panel Interface Installation 5
Installation
Overview
As a basic interface unit between the AXCESS Control System and custom control
systems, the CPI includes the following features.
•Allows connection of up to 64 lamp and contact pairs to the control system.
•Adjustable glow level providing a back-lighted effect to all lamps.
•Individual outputs rated at up to 48 VDC and up to 300 mA. The total
current of all outputs cannot exceed 2 Amps.
•Only one wire connection for each lamp and contact pair required from the
CPI to the custom panel. A maximum of 66 connections including; 64 for the
switches, and 2 for lamp power and contact return common. The maximum
cable length, from your panel (switches and lamps) to the CPI is 30 feet.
•Capable of supplying power to and controlling LEDs, incandescent lamps,
incandescent display tubes, and other similar devices.

Figure 5shows the basic configuration of switches and LEDs connected to the
AXP–CPI. Pin 2 of the captive-wire connector is the positive voltage (plus)
terminal. Be sure to observe polarity. LED supply voltages typically in the 5 V and
12 VDC ranges.
Warning
Only normally open,
momentary contact switches
should be used.

Note
Lamps may be up to 48V

connection must be limited to
less than 300mA, including
inrush current to cold
filements.

Figure 5shows standard connections to the AXP-CPI and a custom control panel.
Other possible options include the following examples:
•Random order connections. Contacts and lamp pairs do not have to be in
sequential order.
•Mixed pairs of switches and lamps. For example, Pin 1 does not have to
connect to lamp 1.
•Lamps without contacts, and contacts without lamps.
•Multiple lamps to one contact, multiple contacts to one lamp.
•Switches wired in parallel, or series, and lamps wired in parallel or series
(within rated power limitations).

connections
Note
Select resistor values to limit
the current for LEDs
according to LED component
specifications. Example, for
12 VDC the value of R1
through R64 would be 1000
ohms. For 5 VDC the value
would be 330 ohms. Both 1/4
watt, 5% tolerance.

AXP-CPI Custom Panel Interface AXCESS Programming 9
AXCESS Programming
Overview
This section describes AXCESS programming for the AXP-CPI. For detailed
information about the AXCESS programming language, refer toe the AXCESS
Programming Guide and AXCESS Language Tutorial.
Programming the AXP-CPI
Using the device code number, the AXP–CPI is interpreted by the control system as
a set of up to 64 inputs and up to 64 outputs. Using a [CPI,2]=[RELAY,1] AXCESS
command, the lamp connected to Pin 2 follows the status of relay 1 on the relay
card ‘RELAY’.
Closing the contact connected to panel connector pin number 2will activate a
PUSH[CPI,2] command.
Where CPI is the AXP-CPI device code, PUSH is an AXCESS program command,
and ‘2’ is the panel connector pin number connected to the custom panel.
Accordingly, the control system is only aware of the connection on the front panel
connector and not the actual arrangement of contacts and lamps on your custom
panel.
Bargraph programming is the same as all AMX SoftWire control panels. Standard
bargraph modes are 0, 1, 2, 3, and 8.
Glow level
The glow level adjustment on the back panel allows you to set the background
light level on all the lamps connected to the AXP–CPI.
Note
Note that you can have a
maximum of 255 devices
connected to any one
AXCESS CardFrame. This
can be combinations of AXP–
CPI units and other AXCESS
AXlink bus controlled units.
