Introduction
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
The front panel of the AXP-CPI features a 64-pin panel connector for the ribbon cable interface and a 2-pin connector for lamp power.
Front panel connectors
- 64-pin Ribbon Cable Connector: Provides 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. The maximum cable length from your panel (switches and lamps) to the CPI is 30 feet.
- 2-pin Captive-wire Connector: Used for contact common and lamp power connections. It supports a maximum voltage of 48 VDC and a maximum current of 2.0 Amps. Suggested lamp voltages are 5–28 VDC. Pin 2 is the voltage plus terminal, and Pin 1 is the lamp minus voltage and the contact common connection.
- 3-wire Mini-jack: Provides signal, 5 VDC, and ground for bargraph control in 5 modes (0, 1, 2, 3, and 8). These LED bargraphs are equivalent to standard SoftWire panel bargraphs.
Back Panel
The back panel of the AXP-CPI houses signal, control, and power connections. It includes AUX Power, AXlink plus (AXP) and minus (AXM) signals, an AXlink active LED indicator, a lamp glow level adjustment, and the input connector for lamp power. System device code switches are also located on the back panel.
Back Panel Arrangement
- Aux Power: 12 VDC power supplied to the AXP-CPI from a standard AMX power module using a 2-pin captive-wire connector. Aux Power is not required when power is supplied from the AXlink connector.
- AXlink: Connections for the AXCESS system bus and 12 VDC power to the AXP-CPI, using a 4-pin captive-wire connector.
Device Number
An identification number used by the AXCESS system. An 8-position SIP switch defines the AXP-CPI as an AXlink device, allowing for one of 255 devices in the AXCESS Control System. The device number is set by the total value of all ON (down) positions. For example, switches 1 and 8 ON define device number 129 (1 + 128 = 129).
Note: The device number takes effect only on power-up. If the device number is changed, the AXlink connector must be removed and reconnected to reset the new device number in memory.
| Switch | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
|---|---|---|---|---|---|---|---|---|
| Value | 1 | 2 | 4 | 8 | 16 | 32 | 64 | 128 |
AXlink (lamp)
An LED used to indicate activity of the AXlink bus connected to the AXCESS system.
Glow Level
This adjustment on the back panel allows you to set the minimum brightness for the lamps, providing 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 for this power connection.
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.
- Requires only one wire connection for each lamp and contact pair from the CPI to the custom panel. A maximum of 66 connections are supported: 64 for 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.
Configuring the AXP-CPI
Warning: Only normally open, momentary contact switches should be used.
Note: Lamps may be up to 48V types. Current at each connection must be limited to less than 300mA, including inrush current to cold filaments.
Basic lamp and switch connections (Incandescent Lamps)
Figure 4 shows the basic configuration for switches and incandescent lamps connected to the AXP-CPI. The 64-pin ribbon connector on the left connects to the custom panel switches. The 2-pin Phoenix connector on the right connects to lamps. Pin 1 of the 2-pin connector is the 'Switch Common', and Pin 2 is for 'Lamps'. External switches (SW1-SW63) are connected to the 64-pin connector. Incandescent lamps (L1-L64) are connected between the 2-pin connector (Pin 2) and the corresponding pin on the 64-pin connector.
Basic LED and switch connections
Figure 5 shows the basic configuration of switches and LEDs connected to the AXP-CPI. Similar to incandescent lamps, external switches (SW1-SW64) connect to the 64-pin connector. LEDs (CR1-CR64) are connected with series resistors (R1-R64) to the 64-pin connector and the 2-pin connector. Pin 2 of the 2-pin captive-wire connector is the positive voltage (plus) terminal, and Pin 1 is the common. LED supply voltages typically range from 5 V to 12 VDC.
Note: Select resistor values to limit the current for LEDs according to LED component specifications. For 12 VDC, the value of R1 through R64 would be 1000 ohms. For 5 VDC, the value would be 330 ohms. Use 1/4 watt, 5% tolerance resistors.
Hookup variations
Figure 5 illustrates standard connections to the AXP-CPI and a custom control panel. Other possible connection options include:
- Random order connections: Contacts and lamp pairs do not need 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).
AXCESS Programming
Overview
This section describes AXCESS programming for the AXP-CPI. For detailed information about the AXCESS programming language, refer to the AXCESS Programming Guide and AXCESS Language Tutorial.
Note: You can have a maximum of 255 devices connected to any one AXCESS CardFrame. This can include combinations of AXP-CPI units and other AXCESS AXlink bus controlled units.
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. An AXCESS command like [CPI,2]=[RELAY,1] allows the lamp connected to Pin 2 to follow the status of relay 1 on the relay card 'RELAY'.
Closing the contact connected to panel connector pin number 2 will activate a PUSH[CPI,2] command. Here, 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. The control system is only aware of the connection on the front panel connector, not the actual arrangement of contacts and lamps on your custom panel.
Bargraph programming
Bargraph programming is the same as for 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.

Bargraph Cable
Figure 8 shows the wiring diagram for the bargraph cable assembly. The cable uses a stereo mini-jack connector with Tip (Data), Ring (+5V DC), and Sleeve (Ground) connections. The maximum cable length is 30 ft.
Bargraph Connection
Figure 9 shows the cable connections for a single bargraph on the AXP-CPI. For connecting two to four bargraphs, cascade the connections from one board to the next. Figure 10 illustrates how to connect multiple bargraphs.
Single bargraph connections
The bargraph module (e.g., 50-0776 REV. x AX-BAR) has a J1 connector for input from the AXP-CPI, with pins for GND, DATA, and +5VDC. It also has a J2 connector for 'Multiple Bargraph Output'.
Multiple bargraph connections
For connecting multiple bargraphs (Bargraph 1, 2, 3, 4), the J2 output of one bargraph connects to the J1 input of the next. A modification is noted for Bargraphs 2, 3, and 4: cut pin 2 from the J2 connector and connect pins 1 and 2.
