Service USB RS232

 

Description

Service USB RS232 is reduced to the smallest 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 known a serial port, like FileMaker, 4th Dimension or AppleScript can control the RS232 port.

Service USB RS232 is mainly used for controlling receipt printers from either 4th Dimension or FileMaker.

 

System requirements

A Macintosh with USB and OSX 10.5 to 10.8 is required to operate Service USB RS232. Up to 100 Service USB RS232 can be controlled by one Macintosh.
