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

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.

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.
