AXLink connector AXLink Status LED Device DIP Switch Input On/Off SIP Switch HI/LO Reference POTs 20-pin Header Connect this side to PC board. 1 AXP-AI8 Specifications Specifications 20-pin Berg header AXlink connector AXlink Status LED Connects to either a ribbon cable (up to 30 feet) or mounts directly into a PC. Blink patterns include: · Off - No power, or the controller is not functioning properly. Device numbers match the programmed device numbers in the Axcess program. Cables Device DIP Switch POTs Power requirement Input voltage range Signal Inputs SIP Switch 3 feet (91. 4 cm) of ribbon cable with a female 20-pin header. HI and LO reference POTs maximize the resolution of joystick operation. Input voltage range of 0 to +5volts (maximum input voltage is +5volts) 8 analog inputs, measured with 10 bit resolution. 8-position SIP Switch to turn off unused inputs. To create a wiring diagram, use the AXP-AI8 System Worksheet on page 7.

The device number must match the assignment of the device in the Axcess program. For example, the DIP switch below defines device number 129 (1+128=129). Switch 1 2 3 4 5 Value 6 7 8 ON 12345678 1 2 4 8 16 32 64 128 AMX standard device numbers are assigned as follows: Cards are 1 through 95. If you later change the device number, remove and reconnect the AXlink connector. Setting the input SIP switch Set the SIP switch positions to ON (down) to disable the corresponding unused inputs. In the illustration above, switches 1 and 8 are ON, designating that input 1 and 8 are disabled. The default setting is all switch positions set to off, enabling all inputs. Setting the joystick range POTs Most applications will use the factory default setting of the POTs and do not require any adjustment. In applications where the input signal is not powered by the AXP-AI8 board and the maximum input voltage range is less than 5 Volts, the output reading may be adjusted closer to full scale, providing greater resolution. [. . . ] Using this method, you have the option of using the HI and LO adjustments to achieve a full 0-5 VDC range, 2. 5 V center, or to adjust the Axcess programming to the actual values sent from the AXP-AI8 inputs.
