Accessories & Modifications Serial Communication Adapters

  • The PDA8068 USB serial adapter is used to connect the PD6830, PD6830X, and PD6730 directly to a computer via USB. This module connects the internal electronics module directly to a computer, and only allows for programming of the units. No live monitoring is possible with this module. This is ideal for quickly connecting to MeterView EX or ScanView EX for programming. USB and meter to adapter cables are included.

  • The PDA8006 Trident USB serial adapter is the perfect adapter to use with the Trident when the only serial communication required is for MeterView running on a PC. It is the least costly option as well. USB and meter to adapter cables are included.

  • The PDA7232 Trident RS-232 serial adapter converts the serial output of the PD765 Trident meter to an unbalanced, full-duplex RS-232 signal. Since it is an external device, one PDA7232 in conjunction with free MeterView software can be used to program and calibrate any number of Trident meters.

  • The PDA7422 Trident RS-485 serial adapter converts the serial output of the PD765 Trident meter to balanced, full or half-duplex RS-422 or RS-485 signals.

  • 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.

  • 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.
