10/100BaseTX RJ-45 Twisted Pair: This Ethernet port drives a twisted pair cable up to
328 ft (100 m). Use data grade twisted-pair wire. This wire must have a characteristic
impedance of 100 ohms and meet the EIA/TIA Category 5 standard wiring specifications.
The cable can be either Shielded Twisted Pair (STP) or Unshielded Twisted Pair (UTP).
UTP is commonly used in the United States, and STP is commonly used in Europe.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
•
Only qualified workers should install this equipment. Such work should be performed
only after reading this entire set of instructions.
NEVER work alone.
Quick Start Checklist
100BaseFX Fiber Optic (EGX400): The fiber-optic port allows the EGX400 to
communicate with a fiber optic based Ethernet LAN. The port is a duplex LC connector
receptacle and is compatible with 1310 nm wavelength multimode fiber connections. It is
optimized for 62.5 or 50/125 micron multimode graded index glass optical fiber. The
transceiver is capable of signal integrity in up to 6,562 ft (2,000 m) of multimode fiber. This
port supports both half-duplex and full-duplex fiber-optic cable.
❏
❏
Wire the control power.
•
•
Configure the Ethernet communications with HyperTerminal (using a null modem
cable) or with a web browser (using an Ethernet crossover cable).
Before performing visual inspections, tests, or maintenance on this equipment,
disconnect all sources of electric power. Assume that all circuits are live until they
have been completely de-energized, tested, and tagged. Pay particular attention to
the design of the power system. Consider all sources of power, including the
possibility of backfeeding.

❏
Configure the serial ports.
Configure the device list.
Wire the serial ports.
Mount the unit.
NOTE: The EGX400 is shipped with a dust cover inserted into the fiber-optic port because
the port is sensitive to dust. The dust cover should remain in the fiber-optic port at all times
except when it is removed to insert a fiber-optic cable. Retain the dust cover for future use.
•
Turn off all power supplying the equipment in which the EGX is to be installed before
installing and wiring the EGX.
•
•
Always use a properly rated voltage sensing device to confirm that power is off.
INSTALLATION
Ethernet Configuration
Beware of potential hazards, wear personal protective equipment, and carefully
inspect the work area for tools and objects that may have been left inside the
equipment.
Before configuring the EGX, obtain a unique static IP address, subnet mask, and default
gateway (router) address from your network administrator.
Control Power Wiring
•
The successful operation of this equipment depends upon proper handling,
installation, and operation. Neglecting fundamental installation requirements may
lead to personal injury as well as damage to electrical equipment or other property.

NOTE: The EGX must be properly connected to a true earth ground. If needed, another
power supply can be used to power the EGX as long as the power supply is rated for a
minimum of 8 watts at 24 Vdc ( 10% regulation). See “Specifications” on page 2 for more
information about the power supply.

Configuring Serial COM Ports
1. Click Device List.
2. In the COM 1 and COM 2 columns, enter the device Address, Device Name, and
Device Type for each attached device on the daisy chain.
3. Click Update, then click Home.
1. Attach a null modem cable (see below).
1. Connect an Ethernet crossover cable from the EGX to the computer.
1. Click Communications Settings.
2. Select the baud rate, parity, and wiring mode for the serial COM port.
NOTE: Attached serial devices must have the same baud rate, parity, and wiring mode
settings. If you are using RS-485, set the mode according to whether your daisy chain is
2-wire or 4-wire. The two serial ports on the EGX are configured independently from each
other and can have different settings.
