Description
The FORCE PMC422FP is a high-performance PMC (PCI Mezzanine Card) module designed to provide robust serial communication capabilities for embedded computing systems. It is engineered to deliver high-speed, multi-channel RS-422/RS-485 connectivity in a compact mezzanine form factor, making it ideal for integration with 3U/6U VME or CompactPCI carrier boards.
Product Introduction
The FORCE PMC422FP is an expansion module that adds four independent, high-speed serial channels to a host processor. By utilizing the RS-422/485 electrical standard, the card ensures reliable data transmission over long distances and in environments with high electromagnetic interference. Its design focuses on flexibility, allowing each channel to be individually configured for specific industrial communication protocols.

Application Areas
The FORCE PMC422FP is widely deployed in mission-critical and industrial systems:
- Industrial Automation: Interfacing with PLC networks and long-distance motor controllers.
- Defense & Aerospace: Tactical communication links and sensor data acquisition.
- Transportation: Signaling systems and onboard data processing for rail and maritime.
- Energy: Monitoring remote equipment in power substations via RS-485 multidrop loops.
Product Technical Description
- Differential Signaling: Utilizes RS-422/485 differential levels to provide superior noise immunity compared to standard RS-232.
- FPGA Integration: Many versions utilize an onboard FPGA to manage timing and signal routing, ensuring deterministic data throughput.
- Isolation: Designed with circuit protection to safeguard the host carrier board from voltage spikes on the serial lines.
- Versatile I/O: Supports both Front Panel I/O (FP) and optional Rear I/O (via P14 connector) depending on the host carrier configuration.
Instructions for Use
- Mounting: Align the PMC module connectors with the host carrier board (VME or CPCI card). Secure the module using the four mounting screws to ensure mechanical stability.
- Configuration: Configure the termination resistors (typically 120 ohms) via onboard jumpers if the module is located at the end of an RS-485 network.
- Driver Installation: Install the appropriate serial drivers for your Operating System (VxWorks, Linux, or Windows). The card will appear as standard COM or TTY ports.
- Cabling: Use shielded twisted-pair (STP) cables for all RS-422/485 connections to maximize data integrity over long distances.
- Status Check: Monitor data transmission via system software diagnostics to ensure no parity or framing errors occur.
