The operating temperature range is between -40 °C to
+85 °C. Very low temperatures can cause a rigidity of
the USB cable, in this case handle with care. For
improving characteristics, special covering passivation
has been applied to PCB of your UCAB232i converter.
1.4.6
Compact enclosure
Compact design of the UCAB232i converter enclosure
with 1 meter cable is most suitable for connection to
any RS232 device.
USB232i is supplied without screwlocks on DB9
connector because some applications do not support
them. On special request it is possible to supply
the USB232i converter with screwlocks included.
