5. Set the COM properties as follows: Bits per second = 19200, Data bits = 8, Parity = None, Stop bits = 1,

and Flow control = None.

6. Click OK.

7. Start the ETG Setup Utility:

a. Cycle power or press the reset button on the ETG.

b. While the green Power/Status LED blinks rapidly, press Enter on the computer keyboard to access

the setup utility. See Table 2 for a description of the setup options.

NOTE: The Power/Status LED stops blinking after 5 seconds.

Serial Configuration

1. Start Internet Explorer.

2. In the Address text box, type the IP address assigned to your ETG, then press Enter.

3. Type Administrator for your user name, type Gateway for your password, then click OK.

4. Click Serial Port or Device List as appropriate and proceed to the sections below.

Serial Port

1. Click Serial Port.

2. Select the mode, physical interface, transmission mode, baud rate, and parity for the serial COM port.

NOTE: Attached serial devices must have the same baud rate, parity, and wiring mode settings. If you are

using RS485, set the mode according to whether your daisy chain is 2-wire or 4-wire.

3. If Mode is set to Slave, enter a unique IP address for each remotely connected device. See the User’s

Guide 63230-319-211 for more information about the slave mode.

4. Click Apply to save changes.

Device List

For daisy-chain devices on the COM port:

• In Master mode, Modbus devices do not have to be defined in the Device List, but it helps you manage

your system.

To set up the Device List for the ETG:

1. Click Device List.

2. Select the number of viewable devices (1 to 128). The default number of devices is eight.

3. In Master mode, enter the Local ID for each attached device on the daisy chain. In Slave mode, enter

the Local ID, Remote ID, and select the Connection for each device that needs to be remotely

connected.

4. Click Apply.

RS485 Wiring

NOTE: For surge protection, we recommend connecting the shield wire directly to an external earth ground

at a single point. For instructions on wiring common Schneider Electric devices, see the wiring instructions

on the ETG100 Technical Library CD.

4-wire Devices

NOTE: The color code shown is for Belden 8723. The color code for Belden 9842 is Blue/White (Tx+),

White/Blue (Tx-), Orange/White (Rx+), and White/Orange (Rx-).

RS485 Biasing and Termination

RS232 Serial Port

NOTE: The ETG pinout for the RJ45 (RS232) is compliant with the EIA/TIA-561 standard. To ensure

proper connections with other Schneider Electric products, examine the wiring for each device. See the

wiring instructions on the ETG100 Technical Library CD for more information, or contact your local

Schneider Electric support representative.

The RS232 port is used to configure the ETG network parameters, and also can be used for serial

communication using Modbus. The ETG RS232 port is wired as a data terminal equipment (DTE) device

and uses a standard RJ45 connector.

NOTE: An RJ45 to DB9 adapter is included in the TCSEAK0100 configuration kit (sold separately) for use

with an Ethernet crossover cable.

SPECIFICATIONS MAINTENANCE AND TROUBLESHOOTING

Maintenance

The ETG does not require maintenance, nor does it contain any user-serviceable parts. If the ETG

requires service, contact your local sales representative for help. Refer to the technical support contacts

provided in the shipping carton for a list of support phone numbers by country. Do not open the ETG

enclosure; this will void the product warranty agreement.

Diagnostics

The Diagnostics page served by the ETG, displays diagnostic data that may be helpful in troubleshooting

network problems. This page also contains information about your specific ETG, including the serial

number, manufacturing date, and media access control (MAC) address. Clicking the Reset button on this

page clears all cumulative counters.

NOTE: This page will show accumulated readings since the ETG was last activated. If power to the ETG is

lost, all values reset to zero.

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

• This equipment must be installed and serviced only by qualified personnel.

• Qualified persons performing diagnostics or troubleshooting that require electrical conductors to be

energized must comply with and follow safe electrical work practices. For example, in the USA, see

NFPA 70E.

Failure to follow these instructions can result in death or serious injury.

Problem Possible Cause Solution

Power/Status LED

Source power is not

applied or is not stable.

Apply power or check power source.

LED is burned out. Check to see if other LEDs operate properly.

Ethernet link LED

Proper link is not

established.

Make sure the proper cable is used and connected.

Make sure the proper media type is selected in the ETG

Communications setup configuration.

The IP address that the

ETG was assigned is

being used by another

networked device.

Assign a new IP address to the ETG or to the conflicting

device.

NOTE: When a duplicate IP address is detected, the ETG

resets its specified IP address to the default IP address.

When the ETG detects the conflict no longer exists, it will

use the specified IP address.

Cannot browse the

ETG.

Incorrect network

configuration.

Verify all IP parameters are correct.

Verify ETG receives requests (ping ETG by going to DOS

prompt and typing “ping” and the ETG IP address, e.g.,

ping 169.254.0.10).

Verify all browser internet options connections settings

are correct.
