PDA1232 ProVu RS-232 Serial Adapter

Brand: Precision Digital Corporation

The PDA1232 converts the serial output of the ProVu meter to an unbalanced, full-duplex RS-232 signal.

The RS-232 port has a female DB9 connector with pins 2: RX output, 3: TX input, and 5: Signal Ground. Pins 7: RTS and 8: CTS are tied together, and pins 1: CD, 4: DTR, and 6: DSR are tied together.

The adapter is powered by the ProVu meter M-Link connection.

The PDA1232 has three diagnostic LEDs: a Power: P LED to show when the adapter is powered properly, a Transmit Data: TX LED to show when the adapter is sending data out from the PC side, and a Receive Data: RX LED to show when the adapter is receiving data from the ProVu meter.
