2.2 Power Connectors
The PPC-E7+ 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# 3-640600-3 power connector. 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

PPC-E7+ User Manual.doc -6- Rev 1.3 © 2015 EMAC, Inc.
supply (EMAC part number PER-PWR-00035). The PPC-E7+’s power input uses a switching regulator and allows
a voltage input of +12V DC.
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-E7+, jumper JB1 should be moved to the “A” position.
2.3 Ethernet
The PPC-E7+ 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.
2.4 Serial Ports
The PPC-E7+ 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 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 422. To select RS485, set jumper JB6 to
4xx and jumper JB5 to 485.
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.

2.5 USB Host Ports
The PPC-E7++ provides one, USB 2.0 (USB PortA) high speed host port (JK3). USB PortA and PortB can be
accessed from the bulkhead connector (HDR5). EMAC can provide a cable (CAB-40-004) to access these ports.
In addition to the one USB Host port, the PPC-E7+ 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.

PPC-E7+ User Manual.doc -8- Rev 1.3 © 2015 EMAC, Inc.
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 up to 1 amp of power.
2.6 Audio Port
The PPC-E7+ 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.
2.7 LCD Brightness Control
The PPC-E7+ 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.
2.8 MicroSD Card Socket
The PPC-E7+ provides two a high capacity MicroSD sockets. One socket is resident on the Carrier and
accessible from the board coast line, the other is resident on the module. Both sockets are 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 while the socket on the module does not provide a status LED. 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-E7+ can be read by another computer using an MicroSD card reader. The MicroSD interface is
compatible with Standard and High Capacity MicroSD cards
2.9 Keyboard/Mouse
The PPC-E7+ does not provide a PS/2 type keyboard/mouse interface. However, a USB keyboard and mouse
can be used if required.
2.10 Analog Inputs
The analog inputs are available on HDR1 (see table 5 below) and are labeled as analog_04, analog_05,
analog_06 and analog_07. Note: Using these A/Ds may degrade the touch screen performance and/or accuracy.
2.11 I/O Expansion
The Processor used by the PPC-E7+ provides a number of unused I/O lines. The PPC-E7+ provides access to
these lines on connector HDR1. This 44-pin dual row header contains GPIO lines, SPI bus, I2C bus, A/D lineS,
interrupts and power pins. Signal names listed in the table below are the SoM names as defined in the SoM 200
pin specification.

2.12 Real-Time Clock
The PPC-E7+ is equipped with an external battery for backing up the module’s Real-Time Clock (RTC). Drivers to
access the RTC are included in the operating systems. Jumper JB4 should be placed in the ON position in order
to retain system time when powered down.
2.13 Serial Flash
PPC-E7+ is equipped with 4MB of SPI based serial NOR flash. The PPC-E7+ can high-level boot from either the
Serial Data NOR Flash or the NAND Flash (selected through the low-level bootloader). It is recommended to
high-level boot from the Serial Data Flash, as this Flash is more reliable than the NAND Flash. The NAND flash is
ideal for the Operating System’s File System which can normally handle marked bad blocks.
The Serial Data Flash is connected to SPI0 and uses SPI0_NPCS0 to enable it. The Serial Data Flash also has a
Write Protect Provision. To Write Protect the Serial Data Flash set JB3 to position B. See the software drivers for
details on accessing this.
2.14 PCD-E12 Expansion
If additional I/O is required the PCD-E12 daughter card can be utilized. This card connects to the PPC-E7+ via
SPI bus on connector ABJ1. The PCD-E12 features CAN, A/D, D/A, Serial Ports, and GPIO. For more info on the
PCD-E12 go to:
www.emacinc.com/sbc_pc_compatible/pcm_53e52.htm.
2.15 Status LEDs and Reset
The PPC-E7+ provides two status LEDs, LD1 (Green) and LD2 (Red). These can be controlled independently via
software (GPIO13 & GPIO12 respectively). LD1 and LD2 are located just to the left of the SD/MMC socket.
Also provided is a Reset Button (PB1). Pressing this button will cause the system to reset.
