MOTOROLA PMC422FP 8-Port RS422/485 PMC Serial Controller Card
MOTOROLA PMC422FP is a PMC standard 8-port multi-serial communication controller card, compatible with VME and CompactPCI single board computers. It supports RS232, RS422 and RS485 serial standards, equipped with 64-byte FIFO buffer per channel to reduce host CPU interrupt load.
This serial card adopts front panel 68-pin SCSI connector for 8 serial ports output, and also supports rear J4 backplane routing. It is industrial-grade long-life legacy spare, widely used in aerospace, power and heavy industrial embedded control system maintenance and replacement.

FAQ
| No. | Question & Answer |
|---|---|
| 1 | Q: What is MOTOROLA PMC422FP? A: It is 8-port PMC serial controller card, used to expand multi-channel RS232/422/485 serial ports for VME/CPCI single board computer. |
| 2 | Q: What is the difference between PMC422 and PMC422FP? A: PMC422FP routes all 8 serial ports to front panel 68pin SCSI connector; standard PMC422 only has 4 front RJ45 ports. |
| 3 | Q: What host board can this card be installed on? A: It can work with any single board computer equipped with PMC slot, including VMEbus and CompactPCI SBC. |
