EtherPath-X4 User’s Guide
Client (Reverse Telnet) Mode
Method 1 (ATD dial mode)
•
The EtherPath must be configured for “ATD” dialing and set for "client".
•
Start the Terminal emulation program (or use a real terminal). The communication settings for this
device must be the same as the values entered into the “Client” EtherPath device earlier.
•
Power up the local EtherPath. It will be in command mode, awaiting a connection command. Type the
command “AT <enter>” to test the RS-232 connection. It should answer with an “OK” message. If
not, correct the RS-232 cable miswiring or terminal program problem. “Dial” a remote telnet server
by using an “ATD” dial command.. “ATD1.2.3.4:5555” , where 1.2.3.4 is the IP address of the remote
telnet server and 5555 is the optional connection port number configured in the remote telnet server.
The EtherPath will automatically connect to the remote telnet server. If an address or port number isn’t
given, the values stored during configuration are used. See the Appendix for a complete list of "AT"
commands and responses.
•
If the EtherPath is in “Client - Echo” mode, you should see the message “Connect OK !” from the
client mode EtherPath when the connection is established
•
You may now proceed as if the remote telnet server was connected to the serial port of your
workstation.
•
Disconnect from that remote telnet server with either the “+++” command or by lowering the hardware
lead on pin six.
Method 2 (Hardware Dial mode)
•
This mode operates with the “Hardware dial (DCD Input ) setting. In this mode, the EtherPath
connects to the configured IP address as soon as RS-232 DCD Input is asserted.
•
The EtherPath must be configured for “Hardware(DCD Input)” dialing and dip switches set for
"client".
•
Start the Terminal emulation program (or use a real terminal). The communication settings for this
device must be the same as the values entered into the “Client” EtherPath device earlier.
•
Power up the local EtherPath. The EtherPath will automatically connect to the remote telnet server
using the values stored during configuration.
•
If the EtherPath is in “Client - Echo” mode, you should see the message “Connect OK !” from the
client mode EtherPath when the connection is established
•
You may now proceed as if the remote telnet server was connected to the serial port of your
workstation.
•
Disconnect from that remote telnet server by lowering the hardware lead on pin six.
