Thank you for purchasing this RS232 to TTL/CMOS Converter. It
is
designed for your PC, workstation, thin client, or server to
provide an instant conversion solution for the device that
needs RS232 interface in TTL or CMOS voltage level. It
provides
a DB9 female connector (DCE, with standard RS232 signals, TXD, RXD,
RTS, CTS and GND) that can be connected directly to your PC
’
s
RS232 port. The product is powered by the RS232 signals so it does not
need any DC power from an external AC Power Adapter.
