See Configuring Dial-Up Connections in Chapter 5 for more information on
configuring your modem. See Dial-Up Networking in Chapter 4 for
information on using Windows Dial-Up Networking for dial-in connections.
Dial-Out Connections
Dial-out connections are normally used with eXpertPower TM applications.
The ETC2002 eXpertPower client can initiate connections to the
eXpertPower
TM server on a time basis. For information on configuring
eXpertPower connections, see Configuring eXpertPower Client in Chapter 5.
To configure your ETC2002 modem for dial-out connections:
1. Set the default Ethernet gateway address to 0.0.0.0 to direct
client connections to the modem network. See Configuring the
Network in Chapter 5 for information on programming the
Ethernet port in your ETC2002.
2. Define your service provider’s phone number, the login name
and the password, and select the modem dialing options: the
number of redial attempts, the time between attempts, and the
connection timeout. Other IP connection parameters are
automatically negotiated with the remote server. See
Configuring
Dial-Up Connections in Chapter 5 for information on configuring
the Dial-Up modem.
NOTE:
If your ETC2002 has both the Ethernet and modem network interfaces, the
eXpertPower client uses one of these for connections to the eXpertPower
TM
server. The default Ethernet network gateway address defines which one of
the networks is used. If the default gateway address is not defined (i.e., it is
set to 0.0.0.0), the ETC2002 uses the dial-out modem connection via your
local Internet provider. If you defined the default network gateway address,
any call to the IP address, which is not included in the address space of the
both networks, is redirected to the default Ethernet gateway.
Serial Master Connections
The ETC2002 can also be used as a serial-to-serial or a serial-to-wireless
gateway. This provides connections to slave networks from serial
applications using the COM3 RS-232 or the COM4 RS-422/485 slave port.
To use the COM3 port as a slave port:
1. Configure the COM3 port communication parameters for your
master application. See Configuring Serial Ports in Chapter 5 for
information on programming serial ports.
2. Ensure that the PROG-RUN switch is in the RUN position.
To use the COM4 port as a slave port:
1. Configure the COM4 port communication parameters for your
master application. See Configuring Serial Ports in Chapter 5 for
information on programming serial ports.
2. Ensure that the COM4 port direction in the port setup is set to
“Slave”.
Routing Messages over Slave Networks
A device address is used to route master requests to a correct network
where the target device is physically located. The device address range is
programmable in the range of 1 through 247. It may be restricted by specific
protocol limitations.
One of the device addresses is reserved for accessing the ETC2002
configuration and data registers. The factory-set ETC2002 network address
is 99. It can be moved to another address via the ETC2002 Gateway Options
setup if you wish to use the default ETC2002 address for addressing your
slave devices.
