This unit
The PMC-Octal Pro-422 is a PCI Mezzanine Card (PMC) that adds eight asynchronous EIA-422 serial communication channels to host systems. Built around two Quad UARTs, this module delivers high channel density in compact form factors, making it suitable for data communications and industrial control applications requiring multiple serial ports. Each channel supports data rates up to 460.8 kbps with 128-byte transmit and receive FIFOs, programmable baud rates from 50 bps to 460.8 kbps, and full control signal support.
The on-board baud rate generator uses a standard 7.3728 MHz oscillator with an empty oscillator site available for custom frequency requirements.
Technical Specifications
- Channels: 8 asynchronous EIA-422 serial ports
- UART Architecture: Two Quad UART devices

Abaco Systems / SBS / Greenspring PMC-Octal Pro-422 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Abaco Systems / SBS / Greenspring PMC-Octal Pro-422. Calibration covers analog input channel accuracy and offset at all gain settings, analog output accuracy, digital I/O logic threshold verification, sample rate and timing accuracy, and trigger and synchronization bus functional verification. NI CompactRIO and PXI chassis also undergo backplane trigger line integrity check.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Abaco Systems / SBS / Greenspring PMC-Octal Pro-422 faults: power supply failure (cRIO-9073/9074), C-series slot connector wear, PXI chassis fan failure, GPIB interface failure on VXI controllers, BIOS/EEPROM corruption. NI CompactRIO most common faults are power supply failure on older cRIO-9073/9074 chassis and C-series module slot connector wear from repeated hot-swap cycles. PXI chassis fan failure is the most common wear item — chassis fans are field-replaceable. VXI embedded controllers most commonly develop EEPROM corruption and GPIB interface failure.
