Parameter Setup
Parameter setup is accomplished in software using SPI (Serial Peripheral Interface)
IMS recommends the MD-CC300-000 USB to SPI converter/cable and the IMS
Motor Interface GUI to configure the parameters. This free software tool is on the
IMS CD and also available from the web at http://www.imshome.com. While the
available parameters are listed below, the device my be operated without changing the
parameters from the factory default.
The SPI Cable plugs into Connector P3, a 10-Pin IDC Style connector located on the
board.
