PPC-E5 Configuration
Jumper & Connector Descriptions
The PPC-E5 comes factory configured. In the event that jumpers need to be verified or modified this
section provides the information required, including instructions on setting jumpers and connecting
peripherals, switches and indicators. Be sure to read all the safety precautions before you begin any
configuration procedure. See Appendix A for connector pinouts and Appendix B for Jumper Settings.

Powering Up the PPC-E5
The PPC-E5’s power connector (CN8) is a standard floppy, four-pin type connector commonly found on
most PC type power supplies. While the PPC-E5’s logic only requires 5 volts DC, the LCD backlight
inverter requires 12 volts DC to operate. Both of these voltages are found on the floppy type connector.
The pinout for the CN8 power connector is as follows:
Pin Signal
1 +5 V
2 GND
3 GND
4 +12 V
Remember before powering-up the PPC-E5 make sure the memory SIMM and the DOC are firmly seated
and check any cables to make sure that plugged on correctly in relation to pin 1.
Note: The PPC-E5 requires less than 2 amps typical which is not enough current to load the main
switcher in some larger PC power supplies (this can be verified with a voltmeter measuring the 5 volt
supply). If this is the case you can try to load the power supply by adding 5 volt devices, or order a
compatible power supply from EMAC.

Memory - Installing DRAM (SIMMs)
You can install anywhere from 4 MB to 64 MB of on-board DRAM memory using 4, 8, 16, 32 or 64 MB 72-
pin SIMMs (Single In-Line Memory Modules). DRAM access time £ 60ns.
•NOTE: The modules can only fit into a socket one way and their gold or silver pins must point down
into the SIMM socket. Make sure you are adequately grounded to avoid memory and PPC-E5
damage.
The procedure for installing SIMMs appears below. Please follow these steps carefully.
1. Ensure that all power supplies to the system are switched Off.
2. Install the SIMM stick. Install the SIMM so that its gold pins point down into the SIMM socket.
3. Slip the SIMM into the socket at a 45-degree angle and carefully fit the bottom of the card against the
connectors.
4. Gently push the SIMM into a perpendicular position until the clips on the ends of the SIMM sockets
snap into place.
5. Check to ensure that the SIMM is correctly seated and all connector contacts touch. The SIMM should
not move around in its socket.
Ethernet
The SMC 91C96 10 BaseT full duplex Ethernet chip uses a standard RJ-45 connector. It can be
connected straight to a hub, or another computer via a crossover Ethernet cable. JP4 is used to set the
Ethernet I/O address and IRQ. The default settings for this jumper block are jumpers in place at positions
A and B. This configuration sets the I/O address at 320H and IRQ 9. Link and Activity (Rx/Tx) LEDs are
provided to monitor network activity.
Serial Ports
The PPC-E5 is equipped with four serial ports, two which are used for on-board functionality, and two
which are available to the user. COM1 and COM2 are used on-board for the SLCC and the touchscreen
controller respectively. COM1 is initialized to 9600 and COM2 is initialized 2400 baud. Both COM1 and
COM2 use 1 start, 1 stop, 8 data bits, and no parity. The user should refrain from reconfiguring these
ports as it may disable the touchscreen and SLCC functionality. The default I/O address and IRQ for
COM1 is 3F8H using IRQ 4. The default I/O address and IRQ for COM2 is 2F8H using IRQ 3.
COM3 and COM4 are available to the user on connectors CN10 and CN11 respectively. These are
standard X86, 16550, 16 byte FIFO UARTS. The default I/O address and IRQ for COM3 is 3E8H using
IRQ 5. The default I/O address and IRQ for COM4 is 2E8H using IRQ 11.
COM3 and COM4 are both by default configured as RS232 ports. COM3 can be optionally factory
configured to an RS422/485 port.

7
Sound and LCD Contrast Controller (SLCC)
The contrast and on-board Speaker volume are software settable via the on-board Sound and LCD
Contrast Controller (SLCC).
Following is the description of the serial data strings that the SLCC accepts and returns. In the
description, XX or xx represent valid hexadecimal numbers in the range 00 to FF and YYYY or yyyy
represent valid hexadecimal words in the range 0000 to FFFF, and AA or aa represent a valid
hexadecimal address from 00 to 3F. The hexadecimal digits are and must be uppercase only.
Contrast
{CXX} Sets the contrast to the value XX (00 is darkest, FF is brightest).
Volume
{VXX} Sets the volume to the value XX (00 is low, FF is high).
Display
{D} Returns the current settings of the contrast and volume as {CxxVxx}.
EEPROM Write
{WAA,YYYY} Writes the 16 bit hexadecimal word YYYY to memory location AA.
Note: Location 00 is the contrast setting and 01 is the volume setting so changing these values will
change the contrast and volume on reset. Locations 2 – 5 are not currently used but are reserved for
future use so should not be used in your application.
EEPROM Read
{RAA} Returns the 16 bit hexadecimal word from location AA as {Raa,yyyy}.
Upon receiving the last character (which is '}' ) of a valid string, the SLCC returns the valid string,
including the '{' and '}'. If an invalid string is sent, nothing happens and no string is returned. The SLCC
is case sensitive and will only accept capital letters for data.
The contrast and volume settings are stored in the serial EEPROM, and these values are applied on
power-up. The EEPROM is a non-volatile storage that does not lose its data on power loss or
disconnection.

8
Keyboard/Mouse
The PPC-E5 is equipped with a keyboard and mouse interface although in normal operation they are not
required if using the touchscreen. Both the keyboard and the mouse utilize the same PS/2 connector
(CN3) through the use of the included Y cable.
Disk-On-Chip Flash Disk
The PPC-E5 comes with a 16 Meg. DOC and 16 Meg. of RAM. The DOC and RAM can be increased to
32 Meg. Optionally.
The DOC is a solid state flash disk and as such is extremely rugged when compared to a conventional
hard drive. The DOC is a paged memory device and is mapped at segment address D000H.
Warning: Be extremely careful when installing the DOC into its socket. Plugging it in backwards
will destroy the DOC and damage the PPC-E5 rendering it inoperable! The DOC comes factory
installed and should not be removed from its socket under normal use.

9
PPC-E5 BIOS Defaults
The PPC-E5 uses a General Software BIOS. To enter the BIOS you must press the <Del> key when
prompted. The following BIOS screen shots indicate the BIOS options and the default factory values of
each option. Note: these factory set options should not require changing.
