Specifications

080505 OPERATIONS MANUAL PPM-GX500 7
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 congured 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 conguration 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 oppy 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
eld 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” oppy disk
drives are also supported. The IDE and oppy 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.
