1. IMPORTANT SAFE HANDLING INFORMATION
WARNING!
ESD-Sensitive Electronic Equipment
Observe ESD-safe handling procedures when working with this product.
Always use this product in a properly grounded work area and wear appropriate
ESD-preventive clothing and/or accessories.
Always store this product in ESD-protective packaging when not in use.
Safe Handling Precautions
This product contains a high density connector with many connections to sensitive electronic components. This
creates many opportunities for accidental damage during handling, installation and connection to other
equipment. The list here describes common causes of failure found on boards returned to Diamond Systems for
repair. This information is provided as a source of advice to help you prevent damaging your Diamond (or any
vendor’s) boards.
ESD damage –This type of damage is usually almost impossible to detect, because there is no visual sign of
failure or damage. The symptom is that the board eventually simply stops working, because some component
becomes defective. Usually the failure can be identified and the chip can be replaced. To prevent ESD damage,
always follow proper ESD-prevention practices when handling computer boards.
Damage during handling or storage –On some boards we have noticed physical damage from mishandling. A
common observation is that a screwdriver slipped while installing the board, causing a gouge in the PCB surface
and cutting signal traces or damaging components.
Another common observation is damaged board corners, indicating the board was dropped. This may or may not
cause damage to the circuitry, depending on what is near the corner. Most of our boards are designed with at
least 25 mils clearance between the board edge and any component pad, and ground / power planes are at least
20 mils from the edge to avoid possible shorting from this type of damage. However these design rules are not
sufficient to prevent damage in all situations.
A third cause of failure is when a metal screwdriver tip slips, or a screw drops onto the board while it is powered
on, causing a short between a power pin and a signal pin on a component. This can cause overvoltage / power
supply problems described below. To avoid this type of failure, only perform assembly operations when the
system is powered off.
Sometimes boards are stored in racks with slots that grip the edge of the board. This is a common practice for
board manufacturers. However our boards are generally very dense, and if the board has components very close
to the board edge, they can be damaged or even knocked off the board when the board tilts back in the rack.
Diamond recommends that all our boards be stored only in individual ESD-safe packaging. If multiple boards are
stored together, they should be contained in bins with dividers between boards. Do not pile boards on top of each
other or cram too many boards into a small location. This can cause damage to connector pins or fragile
components.
Power supply wired backwards –Our power supplies and boards are not designed to withstand a reverse
power supply connection. This will destroy each IC that is connected to the power supply (i.e. almost all ICs). In
this case the board will most likely will be unrepairable and must be replaced. A chip destroyed by reverse power
or by excessive power will often have a visible hole on the top or show some deformation on the top surface due
to vaporization inside the package. Check twice before applying power!
Overvoltage on analog input –If a voltage applied to an analog input exceeds the design specification of the
board, the input multiplexor and/or parts behind it can be damaged. Most of our boards will withstand an
erroneous connection of up to 35V on the analog inputs, even when the board is powered off, but not all boards,
and not in all conditions.
Overvoltage on analog output –If an analog output is accidentally connected to another output signal or a
power supply voltage, the output can be damaged. On most of our boards, a short circuit to ground on an analog
output will not cause trouble.
Overvoltage on digital I/O line –If a digital I/O signal is connected to a voltage above the maximum specified
voltage, the digital circuitry can be damaged. On most of our boards the acceptable range of voltages connected
to digital I/O signals is 0-5V, and they can withstand about 0.5V beyond that (-0.5 to 5.5V) before being damaged.
However logic signals at 12V and even 24V are common, and if one of these is connected to a 5V logic chip, the
chip will be damaged, and the damage could even extend past that chip to others in the circuit.

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.

EMX-ESG User Manual Rev A.1 www.diamondsystems.com Page 6
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. These ports offer RS-232 or logic level I/O. These ports can optionally be
used to communicate with an installed GPS receiver. To do so, both the RS-232 and logic level transceivers are
disabled.
Serial ports 1-2 share one SP336 for protocol selection, and ports 3-4 share a second SP336. Each SP336
requires 2 jumpers for protocol selection, connected to mode pins M0 and M2. Mode pin M1 is tied high for all
protocols.
Ports 1-4 each require 3 jumpers for termination and bias resistors when configured for RS-422 or RS-485 mode.
The termination resistor value is 121 ohms 1%, and the bias resistors are 4.75K ohms 1%.
Ports 5-6 use an SP3245 for RS-232 mode or a logic level driver for logic level signals. Configuration is done as
an assembly option –both transceivers cannot be simultaneously installed for the same port. Each port can be
configured separately. Two jumpers are required for each port to provide independent enable / disable signals for
each driver/transceiver chip in case a GPS module is installed.
All protocol selection and termination / bias resistor selections are made with jumpers. The board contains 0-ohm
resistors that may be installed in place of all jumpers for a more rugged assembly.
3.4 General Purpose I/O
The EMX-ESG offers 14 general purpose digital I/O lines which are provided on an I/O connector. These lines
offer 3.3V logic levels with 5V compatibility. The ports have programmable direction with I/O buffers for protection.
The buffer direction control signals are derived from three other GPIO lines on the SCH3116. On power-up, the
digital I/O ports are in input mode. The digital I/O lines have jumper-configured pull-up/down resistors.
3.5 GPS
EMX-ESG supports a Condor C2626 23-channel GPS receiver.

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.
The base address for the SCH3116 is configured with two jumpers that connect pull-up/down resistors to the
DTR1 (A) and RTS1 (B) signals. These pins are read by the SCH3116 at power-up to define its base address:
DTR1 RTS1 Base address
0 0 0x162E (default)
0 1 0x164E
1 0 0x002E
1 1 0x004E
Ports 1-2 2 jumpers for RS-232/422/485 configuration (RS-232 default)
Ports 3-4 2 jumpers for RS-232/422/485 configuration (RS-232 default)
Set COM6 to either serial port F or the GPS socket.
