The DB9-USB range of modules provide a simple and fast method of migrating existing DB9 based connector UART interfaces to USB 2.0. In some cases this can be done without the need to redesign the PCB. In some cases they can reduce system costs by removing an RS232 level shifter from a design. The modules feature a USB2.0 mini-B connector within a module which fits a standard 9-pin DB9 connector footprint.
Ideal for legacy applications which feature UART DB9 based connectors, these modules provide a method of extending the life-cycle of these products by converting them to USB2.0 connectivity, with minimal redesign.
The DB9-USB family consist of 6 modules. Two of these operate at RS232 voltage levels – these can be used as a direct replacement, with no PCB changes, in a system which uses RS232 levels, while four of them operate at digital voltage levels (a choice of 5V or 3.3V) – these can be used to interface to an application systems logic level which could result in the bill-of-materials being reduced by the removal of any RS232 level shifters which may be present in the system. Each is available to replace either a male or a female DB9.
