| Precision Digital's serial adapters are designed to work with its line of Trident digital panel meters. These adapters are available for RS-232 and RS-485 applications and can connect to the Trident via the standard Precision Digital serial protocol, optional Modbus protocol or via a free LabView driver.
One very important feature of these adapters is that they are external devices, so one adapter can be used to program as many Tridents from a computer as desired. The PDA7488 is an adapter board for serial connection of up to 6 Trident meters. It is particularly useful for data acquisition applications as it simplifies wiring. Precision Digital also offers serial converters to convert RS-232 and USB to RS-485. These converters are available in both isolated and non-isolated versions and will work with any serial device, such as Nova controllers, Fluidwell flow computers, ConsoliDators or any other device with a serial port. Precision Digital provides a free software utility called MeterView which allows the Trident to be programmed from a computer and also collect data.

PDA7232 Trident RS-232 AdapterThe PDA7232 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 an infinite number of Trident meters |
