Page 4: Introduction
2. INTRODUCTION EMX-ESG is an EMX compact format I/O module featuring two PCI Express gigabit Ethernet ports, an LPC UART with 6 serial ports, and 24 GPIO lines. It uses two PCIe x1 links and one LPC clock on the EMX bus. 2.1 Features 2.1.1 Main Feature List 2 Gigabit Ethernet ports on pin headers, with on-board magnetics... -
Page 5: Functional Overview
3. FUNCTIONAL OVERVIEW 3.1 Functional Block Diagram Figure 1. EMX-ESG Functional Block Diagram 3.2 Ethernet Each Ethernet port consists of an Intel 82574IT PCIe x1 Ethernet MAC/PHY. Magnetics and configuration EEPROM are included on the board to provide a complete circuit. www.diamondsystems.com EMX-ESG User Manual Rev A.1 Page 5... -
Page 6: Serial Ports
3.3 Serial Ports EMX-ESG includes an SMSC SCH3116 6-port UART to provide 6 serial ports. Ports 1-4 use Exar SP336 multiprotocol transceivers to support RS-232, RS422, and RS-485. On these ports, signals TX, RX, CTS, and RTS are available in RS-232 mode. In RS-485 mode, the transmitter is controlled by the RTS line. Ports 5-6 have only TX and RX signals. -

6.2 EMX Bottom (J2) Signal names in parenthesis are going to the specified pin number of the top connector (J1). NC means no connects between top and bottom connectors on this board. GND means tied to ground on this board. (J1-03) PCIe TX1+ PCIe TX4+ (NC) (J1-05) PCIe TX1-... -
Page 11: Gpio (J3)
6.3 GPIO (J3) A 26-pin connector provides 14 GPIO lines from the SCH3116, identified as ports A, B, and C. These lines have 3.3V logic levels with 5V input tolerance. The connector also provides access to the 1PPS signal from an optional installed GPS module. -
Page 12: Serial Ports (J4, J5, J6)
6.4 Serial Ports (J4, J5, J6) The SCH3116 offers 6 serial ports. In RS-232 mode, ports 1-4 have TX, RX, CTS, and RTS signals, while ports 5- 6 have only TX and RX signals. The following pinouts are the pin definition of the SP336 transceiver when its protocol is switched between RS-232, RS-422, and RS-485. -
Page 13: Ethernet Leds (J9)
6.6 Ethernet LEDs (J9) Each Ethernet port has 3 LED signals that may be used to drive indicator LEDS. These signals are available on an I/O connector. The signals also drive on-board LEDs. LED1 is the link indicator; an LED is connected between this signal and +3.3VDC. -
Page 14: Jumper Configuration Information
JUMPER CONFIGURATION INFORMATION 7.1 Serial Port Termination (J10) Serial ports 1-4 each require three jumpers per port for 120 ohm termination and bias resistors. The default configuration with no jumpers installed is shown below. Pin 1 Figure 3: Serial Port Termination Jumper Block Pins Termination Enable/Disable 1-2 no jumper... -
Page 15: Address And Protocol (J11)
7.2 Address and Protocol (J11) Jumper J11 provides the configuration jumpers for the GPIO, serial port addresses and protocols and GPS as outlined below. The general purpose DIO pull-up/down setting is configured with two jumpers, one for pull-up (default) and the other pull-down. - Page 16 Pins Setting 1-2 jumper (no 3-4 jumper) DIO pull up to +5V (default) 3-4 jumper (no 1-2 jumper) DIO pull up to +3.3V 5-6, 7-8 jumpers Base address 0x162E (default) 5-6 jumper, 7-8 no jumper Base address 0x164E 5-6 no jumper, 7-8 jumper Base address 0x002E 5-6, 7-8 no jumpers Base address 0x004E...
