40-817M RS232 Technical Info

Postby wesblack on Tue Feb 28, 2012 4:39 pm

The Calrad 40-817M is a 4 x 2 Component video matrix switcher. The unit can operate by front panel selection buttons, IR or using the RS232 control port. In order to control the 40-817M by RS232 you need to plug in the included RS232 dongle. The dongle uses a 4 wire interface cable between the 40-817M and the dongle, make sure the connector header plug is installed correctly following the diagram below. If the connections are correct and a RS232 cable is connected to a RS232 control port the the Blue L.E.D. on top of the RS232 dongle will illuminate, indicating a good connection.
