The AK57X interfaces the models 570A and 575A with the CompactLink software. It allows you to add ICs to the device libraries of the 570A and 575A.
Important Note: The AK57X comes with a Security Dongle that must be connected to the USB port in order to operate the AK57X software. If the Security Dongle is lost, an entire new AK57X kit must be purchased to interface the AK57X with the CompactLink software. To help you keep track of the Security Dongle we have attached it to a BK Precision Pocket Knife Keychain.
