DescriptionSoftware | ManualOrder page


Service USB serialService USB RS232 is the smallest "member" of the series of the universal USB interfaces. It is using the same software as Service USB classic and Service USB plus, but has only the RS232 implemented.

Service USB RS232 is reduced to the minimum possible size and is housed inside the Sub D25 connector. As opposed to ordinary USB/ RS232 converters an abundant supply of software is part of our complete package.

Thus Service USB RS232 can be used by almost every program. Programs, which never have seen a serial port, like FileMaker, 4th Dimension or AppleScript can control the RS232 port.
