RS-232 / RS-485 Adapter

The EM Modules M232 and M485 provide RS 232 and RS 485 interfaces respectively and are ready for USB 2.0.

Like all EM I/O modules it fits on the module rail mounting of the products TB-M and TB-H and can be fixed on this with a screw. It is with hardware of E.E.P.D. / EMTrust as well as with most x86-and ARM third-party hardware compatibly. In addition to the assembly in the module mounting it can be fixed to a hat rail. A variation with 80-cm-long USB cable (type A plug) is also available especially for it.
