PDA8232 USB to RS-232
Converter
Description
The PDA8232 USB to RS-232 Converter allows
for direct connection of a serial device to the
USB port of a PC.
Installation
Figure 23. shows the connection of a Trident
meter to a PC using a PDA8232 USB to RS-232
Converter, PDA7232 RS-232 adapter, and the
PDA7420 Modular Cable.
Figure 23. Connections for PDA8232 to
serial device
When connecting a Precision Digital
ConsoliDator to a PC using the PDA8232 USB
to RS-232 Converter, a Null Modem Cable (not
included) must be used. A Null Modem Cable is
a serial cable that swaps pairs of the wires to
allow the two connected devices to operate as
they would if they were linked using modems.
When connecting the ConsoliDator
to a PC via
the PDA8232, it is strongly recommended to
change the ConsoliDator's parity parameter to
"NONE - 8N2," for None parity, 2 stop bits.
Two PDA7485 RS-232 to RS-422/485 Serial
Converters could be used as a serial extender to
allow RS-232 serial devices to communicate
over long distances. This would allow an RS-
232 serial device, such as the Precision Digital
ConsoliDator, to operate up to 3,937’ (1,200 m).
