Step 1: Plug the 26-pin FPC-cable connector into CN34. Make sure that the red wire
corresponds to pin one on the connector.
Step 2: Attach the appropriate connector on the other end of the cable to the floppy drive.
Only one connector in the set can be used. Step 0:
4.3.4.4 Parallel Port Connector (CN9)
The onboard parallel port connector (CN9) connects to a printer. The ROCKY-3786EV
comes with a multi-mode (ECP/EPP/SPP) parallel port. The parallel port interface features
a 26-pin flat-cable connector that requires an adapter cable if a traditional DB-25
connector is used. The parallel port interface can be re-assigned to LPT2 or LPT3 through
the BIOS configuration utility. The default interrupt channel is IRQ7. Select ECP or EPP
DMA mode using the BIOS configuration utility.
4.3.4.5 Audio Interface
AC’97 Audio signals are interfaced through a 10-pin flat-cable connector. The signals
include microphone line-in, line-in stereo and line-out stereo. An audio
10-pin-to-phone-jack adapter kit is required.
4.3.4.6 COM Port Connectors [CN2, CN8]
The ROCKY-3786EV provides two RS-232 serial ports interfaced through one 14-pin
male header. The serial ports facilitate the connection to serial devices or a
communications network, e.g., terminal console.
4.4 Chassis Installation
The CPU card can be mounted into a chassis only after the CPU, the cooling kit, and the
DIMM module have been installed, the internal peripheral connectors have been
connected to the peripheral devices and the jumpers have been configured.
Refer to the chassis user guide for instructions on how to mount the CPU card into a
chassis.
