Four independent, full-duplex, RS-232 asynchronous serial channels are on-board.
Interface is provided at connector
J8
, which is an 80-pin high-density connector.
WinSystems offers the cable
CBL-251-1
to simplify the connection. The pinouts
for the connector and cable are listed on the following page, as well as connector
variations for RS-232, RS-422 and RS-485.
All serial channels are configured as Data Terminal Equipment (DTE). Both the send
and receive registers of each channel have a 16-byte FIFO. All serial ports have
16C550-compatible UARTs that offer software compatibility with PC-type driver
programs.

Optionally, a USB FLASH drive can be connected in addition to, or instead of the
CompactFlash device. Legacy USB operation is supported by the system BIOS.
Selecting the option
CD-ROM Drive
from the BIOS boot order configuration also
enables boot from a USB device. If a CD-ROM device is already present, the
system will attempt boot from the CD-ROM before attempting boot from a USB
device.

Solid State Disk (SSD) Support
The PPM-GX500 supports solid state CompactFlash storage devices for applications
where the environment is too harsh for mechanical hard disks or floppy drives.
The CompactFlash socket at
J2
supports modules with TrueIDE support.
WinSystems offers industrial grade CompactFlash modules that provide high
performance and extended temperature operation (-40ºC to +85ºC). A red IDE
activity LED is present at
D4
.
When using a CompactFlash device, Master/Slave selection is made using jumper
field
J105,
located on the back of the board.

Rotational Disk Support
An industry standard 16-bit IDE interface is provided to support up to two hard
disks. A status LED,
D4
, provides visual status during IDE data transfers. Note
that the CompactFlash is an IDE device. Use of a CompactFlash device therefore
reduces the number of available hard disks to one. Up to two, 3.5” floppy disk
drives are also supported. The IDE and floppy interface is provided via connector
J109
, which is an 80-pin high density connector. WinSystems offers the cable
CBL-252-1
to simplify the connection. The pinout for the connector and cable is
listed in detail in the
cable drawing
.
