The ISD-200 is a fixed-function device and cannot be programmed. Default configuration information is contained in internal ROM contents, but an external I2C EEPROM can be used to store custom configuration data. See the ISD-200 datasheet that comes with the CD for more information.
Please note that the ISD-200 is obsolete and the functional replacement is AT2LP. All the related collaterals of AT2LP can be found in the link here
