1.4 Jumper Configuration & Connector Descriptions

The PPC-E10 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 Setting descriptions.

Table 1: Jumpers

Table 2: Connectors

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.

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.

Page 10

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.

1.14 I/O Expansion

The Processor used by the PPC-E10 provides a number of unused I/O lines. The PPC-E10 provides access to these lines on connector HDR1. This 44-pin dual row header contains GPIO lines, SPI bus, I2C bus, A/D, interrupts and power pins. Signal names listed in the table below are the SoM names as defined in the SoM 200 pin specification.

1.15 Real-Time Clock

The PPC-E10 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.

1.16 Status LEDs and Reset

The PPC-E10 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.

1.19 U-Boot Bootloader

The PPC-E10 is distributed with Das U-Boot installed. U-Boot is an open source/cross architecture platform independent bootloader. It supports reading and writing to the flash, auto-booting, environmental variables, and tftp. Das U-boot can be used to upload and run and/or reflash the OS on the SoM-3517M without the use of a JTAG cable, or to run stand-alone programs without an OS. SoM-3517M modules are shipped with a valid MAC address installed in flash in the protected ethaddr environmental variable of U-Boot. At boot time U-Boot automatically stores this address in a register within the MAC, which effectively provides it to any OS loaded after that point.

1.20 Linux Tools

1.20.1 Eclipse

EMAC provides sample code for the PPC-E10 as CDT projects within the free Eclipse IDE. Eclipse is a powerful open-source Java based IDE. It has plug-ins for development and debugging in Java and C, as well as several other languages.
