Serial Communication Interfaces
The DSB-Mini has two RS-232 interfaces to communicate with the module’s serial interfaces
ASC0 and ASC1. ASC0 is a full 8-wire UART interface, while ASC1 is a 4-wire UART interface.
If the DSB-Mini is employed together with an adapter like the Multi-Adapter R1 or any other
DSB75 module adapter, the RS-232 interfaces (ASC0, ASC1) on the DSB-Mini are automati-
cally enabled and can be used.
However, if the DSB-Mini is used together with a Starter Kit, the switch ("ASC0") has to be set
to select whether to use the RS-232 interface on the DSB-Mini or the USB-to-UART bridge on
the Starter Kit for ASC0 communication:
•
RS232
If set to "RS232" the module communicates via the RS-232 interfaces on the DSB-Mini. The
USB-to-UART bridge on the Starter Kit is reset and releases all ASC0 serial signals.
•
Starter Kit
If set to "Starter Kit" the module’s ASC0 interface communicates via the USB-to-UART
bridge of the Starter Kit. In this case the RS-232 level shifter on the DSB-Mini releases all
ASC0 serial signals. For more information on the USB-to-UART bridge please refer to the
appropriate Starter Kit documentation (
).
