PDA1485 ProVu RS-485 Serial Adapter

The PDA1485 converts the serial output of the ProVu meter to balanced, full or half-duplex RS-485 signals. 

The PDA1485 has a removable screw terminal connector for the RS-485 terminals which includes Transmit Data (DO) and (/DO), Receive Data (DI) and (/DI), and Signal Ground. The adapter is provided by the ProVu meter M-Link connection. 

The PDA1485 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.
