How to Use

Begin by inserting the Parallax 64006F P2 Eval Serial Device Add-on Board into the designated expansion slot on your Propeller 2 evaluation platform, ensuring proper alignment with the connector pins. Once physically seated, connect your serial devices to the appropriate connectors on the board, selecting either the DB-9 connector for RS-232 devices or the pin headers for TTL-level serial connections. Before powering on the system, verify that your serial device operating voltages match the board's specifications and that all connections are secure to prevent intermittent communication failures.

In your PropellerIDE development environment, initialize the serial communication using Parallax's built-in UART libraries, specifying the appropriate baud rate, data bits, stop bits, and parity settings to match your connected serial device. The board's pin assignments are clearly documented in the accompanying schematic, allowing you to configure software serial objects to the correct physical pins. Test your implementation by transmitting simple command sequences to your serial device and monitoring the response data through the IDE's serial terminal, adjusting timing parameters and buffer sizes as needed for optimal communication performance.

Frequently Asked Questions

What is the difference between RS-232 and TTL serial protocols supported by this board?

RS-232 is a legacy standard that uses bipolar voltage levels ranging from -15V to +15V, commonly found in older industrial equipment and computer peripherals. TTL (Transistor-Transistor Logic) uses 0V to 5V voltage levels and is standard in modern microcontroller applications. The Parallax 64006F includes integrated level-shifting circuitry that automatically converts between the P2's 3.3V TTL levels and RS-232 signal levels, allowing seamless connection to both device types without external conversion modules.

Can I use multiple serial channels simultaneously on this board?

Yes, the board's flexible pin-breakout design allows configuration of multiple independent serial communication channels. You can establish simultaneous communication with different devices by allocating separate pin assignments in your firmware code and creating multiple UART objects in PropellerIDE. The P2 microcontroller's multi-core architecture supports parallel processing of multiple serial streams, enabling true concurrent communication without data loss or timing conflicts.

Does this board require external power supply or does it draw power from the P2 evaluation platform?

The Parallax 64006F P2 Eval Serial Device Add-on Board draws its operating power directly from the Propeller 2 evaluation platform through the expansion connector. No separate power supply is required for the board itself. However, ensure that your P2 platform provides adequate current capacity for both the microcontroller and the add-on board, particularly if you are driving high-current serial devices or multiple channels simultaneously.

What baud rates are supported by this serial add-on board?

The board supports standard baud rates ranging from 300 bps to 115200 bps, with the most common industrial and embedded applications using 9600 bps or 115200 bps. The P2 microcontroller's flexible clock configuration allows custom baud rates beyond these standard values if required by specialized applications. Consult the board's documentation and your connected device specifications to select the appropriate baud rate for reliable communication.

Is this board suitable for long-distance serial communication?

The RS-232 interface on this board supports communication distances up to 50 feet under ideal conditions with standard twisted-pair cabling. For longer distances or noisy industrial environments, consider using RS-485 converters or fiber optic isolation modules in conjunction with this board. Always use shielded twisted-pair cabling and proper grounding techniques to minimize signal degradation and electromagnetic interference in extended-distance applications.
