The universal door board does not communicate through IMS. Have to use the Universal door board App and orange cable. The IMS install disk 2.4.x.x comes with IMS'S, DMCI Fast, Door Fast. and UDC Fast. UDC fast is for the Universal Door Board. All but IMS use the orange cable. RS232 to 485. To use the orange cable the Serial port driver must be changed to ACPI.
