1.3 Description

The PPC-E10 is a rugged embedded Open Frame Panel PC (PPC). The PPC-E10 utilizes a modular System on Module

(SoM) design which extends the longevity and flexibility of the PPC-E10.

The PPC-E10 is comprised of a Processor Module and a Carrier board in which the Module plugs into. If more memory

is required or speed is required a different pin compatible Module offering these features can be inserted into the Carrier

board in place of the standard Module that is provided. Additionally, if the processor or memory go End Of Life another

processor Module can be utilized extending the life of the product.

1.5 Power Connectors

The PPC-E10 provides two power connectors. J1 is an AMP/Tyco locking power connector (part# 640445-3),

three-pin type connector that mates with TE Connectivity part# 647402-3 power connector using crimp pins part#

3-647406-1. Using this power input provides for a more rugged/industrial locking connection. JK1 is a standard

5.5mm barrel jack with an inner diameter of 2.1mm with a center V+ connection. This jack allows for easy

connection to a wall mount power supply (EMAC part number PER-PWR-00035). The PPC-E10’s power input

uses a switching regulator and allows a voltage input of +12Vdc to +26Vdc.

The pinout for the J1 power connector is as follows:

Pin Signal

1 +Vin (+12Vdc to 26Vdc)

2 Chassis GND

3 System GND

Before powering up the PPC-E10, jumper JB1 is in the “B” position

1.6 Ethernet

The PPC-E10 provides 10/100 Base-T full duplex Ethernet and uses a standard RJ-45 connector (JK2). It can be

connected straight to a hub, or another computer via a crossover Ethernet cable. The Ethernet MAC & PHY are

integrated into the SoM processor module. Activity and Link LEDs are integrated into the RJ45 connector.

1.7 Serial Ports

The PPC-E10 is equipped with four serial ports, one of which terminates to a male DB9 and the other three which

terminate to 10pin header connectors (see table 2, 3, & 4 below). Three 10-pin header to male DB9 connector

cables are provided, giving easy access to these ports. Baud Rate, stop bits, etc. are all programmable for each

port via software.

COM A is an RS232 compatible port with a full complement of handshaking lines (through the use of GPIO lines)

allowing it to communicate with modems and other devices requiring hardware flow control.

COM B is an RS232 port. This port offers no handshake lines.

COM C can be configured to RS232, RS422, and RS485 via 2 jumpers. To select RS232 set jumper JB6 to 232

(this is the default). For RS422 set jumper JB6 to 4xx and jumper JB5 to 485. To select RS485, set jumper JB6 to

4xx and jumper JB5 to 422.

When using COM C in the RS422/485 mode, a terminating resistor (~120 Ohm) is recommended on the two far

ends of the network.

COM D is an RS232 port. This port offers no handshake lines.

1.8 USB Host Ports

The PPC-E10 provides two, USB 2.0 (USB PortA & PortB) high speed host ports (JK3). USB PortA and PortB

can also be accessed from the bulkhead connector (HDR5). EMAC can provide a cable (CAB-40-004) to access

these ports.

In addition to the two USB Host ports, the PPC-E10 provides a USB On-The-Go (OTG) port. This port can be

used as either a USB Host or USB Device port.

All of the USB ports are equipped with 500mA re-settable Polyfuses. If a USB Device tries to draw more than

500mA from the port, the fuse will open until the device is unplugged or its current requirement is reduced. There

is no software provision for shutting down power to the Ports or detecting when a port is drawing too much

current.

Note: When sizing a power supply, make sure to allow for USB Device consumption. A device can potentially

draw 500mA, therefore these devices could use a total of over 1 amp of power.

1.9 Audio Port

The PPC-E10 provides Audio Line Out and Line In capability through two standard audio jacks (JK5 & JK6).

Audio Jack JK5 is stereo line level input and Audio Jack JK6 is stereo line level output. The processor interfaces

to the Audio CODEC through its I2S interface. Command control of the CODEC is done using the processor’s SPI

interface. The CODEC is the Cirrus CS4271, which is a high performance 24-bit Stereo CODEC offering superior

sound quality.

Both the input and output are line level. You will probably not be able to drive an unamplified speaker although

standard headphones will work. Likewise, an un-amplified microphone probably will not work as an input although

the line out of a CD player will work.

1.10 LCD Brightness Control

The PPC-E10 offers LCD brightness control that can change the brightness of the LCD via software. The LCD

utilizes LED backlighting. The board provides the backlight with approximately 10 volts at about 220mA. The

processor provides a PWM (SoM pin# 85) that is used to drive the LCD backlight. Changing the duty-cycle of the

PWM directly affects the brightness of the LCD. In addition, the backlight can be turned off or on via SoM port line

GPIO0 (SoM pin#114). This allows screensaver software to automatically turn off the backlight when the unit is

not being used and to automatically turn it back on when the touchscreen is touched.

1.11 MicroSD Card Socket

The PPC-E10 provides a high capacity MicroSD socket. The socket is resident on the Carrier and accessible from

the board coast line. The socket is hot-swappable and can accept a wide variety of Flash Cards. A green activity

light (LED LD3) is located towards the left side of the socket on the Carrier. When the processor is accessing the

Flash card this LED will be lit and the card should not be removed at this time. A card that is written to by the

PPC-E10 can be read by another computer using an MicroSD card reader. The MicroSD interface is compatible

with Standard and High Capacity MicroSD cards

1.12 Keyboard/Mouse

The PPC-E10 does not provide a PS/2 type keyboard/mouse interface. However, a USB keyboard and mouse

can be used if required.

1.13 Analog Inputs

A 12-Bit analog input is available on HDR1 (see table 5 below) and is labeled as analog_04.
