Advantech PCM-9587 user manual Floppy drive connector CN14, Parallel port connector CN16

2.9Floppy drive connector (CN14)

You can attach up to two floppy drives to the PCM-9587’s on-board controller. This is useful with 34 pin dual FDD cable (part no:1701340603).

You can use any combination of 5.25”(360 KB and 1.2MB) and/or 3.5”(720 KB, 1.44MB, and 2.88 MB) drives. An appropriate 34 pin flat cable is required.

2.9.1Connecting the floppy drive

1.Plug the 34-pin dual FDD-cable connector into CN14 of PCM-9587 board. Make sure that the red wire corresponds to pin one on the connector.

2.Attach the appropriate connector at the end of the cable to the floppy drive(s). You can use only one connector in the set. The set on the end (after the twist in the cable) connects to A: drive. The set in the middle connects to the B: drive.

If you are connecting a 3.5” floppy drive, you may have trouble determining which pin is number one. Look for a number printed on the circuit board indicating pin number one. In addition, the connector on the floppy drive may have a slot. When the slot is up, pin number one should be on the right. Check the documentation that came with the drive for more information.

If you desire, connect the B: drive to the connectors in the middle of the cable as described above.

In case you need to make your own cable, you can find the pin assignments for the board’s connector in Appendix B.

2.10Parallel port connector (CN16)

Normally, the parallel port is used to connect the card to a printer. The PCM-9587 includes a multi-mode (ECP/EPP/SPP) parallel port accessed via CN16 and a 26-pin flat-cable connector. You will need an adapter cable if you use a traditional DB-25 connector. The adapter cable has a 26-pin connector on one end, and a DB-25 con- nector on the other.

The parallel port is designated as LPT1, and can be disabled or changed to LPT2 or LPT3 in the system BIOS setup.

The parallel port interrupt channel is designated to be IRQ7. You can select ECP/EPP/SPP DMA channel via BIOS setup.

2.11Keyboard and PS/2 mouse connector (CN27)

The PCM-9587 board provides a keyboard connector that supports both a keyboard and a PS/2 style mouse. In most cases, especially in embedded applications, a key- board is not used. If the keyboard is not present, the standard PC/AT BIOS will report an error or fail during power-on self-test (POST) after a reset. The PCM-9587’s BIOS standard setup menu allows you to select “All, But Keyboard” under the “Halt On” selection. This allows no-keyboard operation in embedded system applications, with- out the system halting under POST.
