Setting the AXlink Device Number
The 8-position device DIP switch defines the AXP-CPI16 as an AXlink device. It 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 device DIP switch shown below defines device number 129 (1+128=129).
Position12345678
Value 1 2 4 8 16 32 64 128
OFF
OFF
ON
ON
1 2 3 4 5 6 7 8
AMX standard device numbers are assigned as follows:
Cards are 1 through 25.
Boxes are 96 through 127.
Panels are 128 through 255.
1. Strip 0.25 inch of wire insulation off all wires.
2. Insert each wire into the appropriate opening on the connector according to the wiring diagrams and
connector types described in this section.
3. Tighten the screws to secure the wires. Do not tighten the screws excessively; doing so may strip the
threads and damage the connector.

Connecting the AXlink Wiring
To install the AXlink data/power bus wiring.
1. Strip 0.25 inch off the wire insulation for all four wires. If the wire is 20 AWG or less, fold the
exposed wire over to obtain a positive connection.
2. Insert each wire into the appropriate opening on the connector, as shown in FIG. 3.

Programming
Use the same Axcess commands as with other AXlink control panels, such as the AXU-MSP series
mini-softwire panels. When using the AXP-CPI16 as a control device, use On, Off, and Pulse commands
to control sources connected to outputs and Push and Release commands to receive inputs. For
additional information, refer to the Axcess Programming Language instruction manual.
Send_Commands
Command Description
'STATUS-ON' Causes the AXP-CPI16 to be in Status-On Mode.
'STATUS-OFF' Causes the AXP-CPI16 to be in Status-Off Mode.
The AXP-CPI16 uses input channels to report user input on the contacts or switches attached to the input
terminals. Output channels are used to turn on the lamp or LED display devices to indicate the button
status to the user.
The AXP-CPI16 default mode is STATUS-OFF, and in this mode the programmer cannot poll the AXPCPI16 to determine the state of the output channel. This is because in this mode the output and input
channels use the same number assignments. Inputs are sent by the AXP-CPI16 only as input changes.
When set for STATUS-ON mode the output channels are assigned a different channel number than the
input channels. This allows the programmer to monitor the status of an output channel. However the
channel offset must be accommodated in the programming code. Statements such as this example can be
used in a program.
IF[CPI16,25] (* output channel assigned to input channel 9 on P3 connector *)
Programming
This command overrides the mode setting.
This command overrides the mode setting.
Each of the two 20-pin connectors is assigned a group of 8 input and output channels. The table below
shows the relation of input and output channels in the STATUS modes.
Input/Output STATUS Mode
Mode Connector STATUS-OFF (default) STATUS-ON
Inputs P2 Chan 1-8 (Push/Release only) Chan 1-8 (On/Push/Off/Release)
P3 Chan 9-16 (On/Off only) Chan 17-24 (On/Off)
Outputs P2 Chan 1-8 (Push/Release only) Chan 9-16 (On/Push/Off/Release)
P3 Chan 9-16 (On/Off only) Chan 25-32 (On/Off)
The AXP-CPI16 may be configured to default to STATUS-ON mode using the following method. The
commands can force a change to the mode no matter what default mode is configured for the device.
STATUS-ON Mode:
Remove R7 (1K ohm) resistor OR short across R8 for STATUS-ON mode. Firmware remains the same
for standard and STATUS-ON mode AXP-CPI16 units.

Testing the Unit
If you have programmed the Axcess software, load the program into a PC connected to the control
system Master port. See Programming on page 4.
1. Push switches connected to the AXP-CPI16.
2. Look at the lower left of the Axcess screen to verify that the correct device and channel numbers are
displayed.
3. Check for the appropriate feedback (as provided by the Master Controller program).
