2.1 Jumper Configuration & Connector Descriptions

The SOM-210 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.

2.2 Power Connectors

The SOM-210 provides two power connectors. HDR4 is a standard PC Floppy disk power connector, four-pin type connector that mates with standard Floppy disk drive power connector. Using this power input provides for a more rugged/industrial locking connection. JK4 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-00032). The SOM-210’s power input uses a switching regulator and allows a voltage input of +5V DC.

The pinout for the J1 power connector is as follows:

Pin Signal

1 +5V DC 2 Chassis GND 3 Chassis GND 4 +12V DC (unused)

2.3 Ethernet

The SOM-210 provides 10/100 Base-T full duplex Ethernet and uses a standard RJ-45 connector. 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 SOM-210 is equipped with three serial ports, all of 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 the RTS and CTS handshake lines. COM C can be configured to RS232, RS422, and RS485 via 4 software controlled port pins (see table 1 below).

To select RS232 set SoM pin 113 & 120 Low and pin 118 & 119 High (this is the default). For RS422 set SoM pin 113 & 120 High and pin 118 & 119 Low. To select RS485, selectively set SoM pin 113 & 119 as required while keeping pin 118 Low.

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

2.5 USB Host Ports

The SOM-210 provides two, USB 2.0 full speed host ports. USB PortA and PortB can be accessed from the onboard USB connectors JK3 and JK2.

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 (option on Rev1 and greater boards)

The SOM-210 provides Audio Line Out and Line In capability through a 10-pin 2mm header. A special cable converts the signals present on the header to two miniature audio jacks. The processor interfaces to the Audio CODEC through its I 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.

S interface. Command control of the CODEC is done using the processor’s SPI interface.

2.7 LCD Brightness Control

The SOM-210 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 33 volts at about 20mA. The processor provides a PWM 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 by reducing the PWM rate to 0. 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 SOM-210 provides a high capacity MicroSD socket. This socket is hot-swappable and can accept a wide variety of Flash Cards. A green activity light (LED LD2) is located towards the left side of the socket. 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 SOM-210 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 SOM-210 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 HDR2 (see table 5 below) and are labeled as analog_04, analog_05, analog_06 and analog_07. These may or may not be supported by the SoM plugged into this carrier.

2.11 I/O Expansion

The Processor used by the SOM-210 provides a number of unused I/O lines. The SOM-210 provides access to these lines on connector HDR2. This 30-pin dual row header contains GPIO lines, SPI bus, I interrupts and power pins. Signal names listed in the table below are the SoM names as defined in the SoM 200 pin specification.
