Making Hardware Connections

A triple DIP (dual inline package) switch allows the Serial Server to be placed into Console Mode. When all three switches are moved into the ON position the Serial Server enters Console Mode, allowing configuration of the Serial Server (using an RS-232 connection through the serial port on the ESP901 or Serial Port 1 on the ESP902) from a PC running a terminal program such as HyperTerminal. When the Serial Server enters Console Mode the Console Mode screen will appear in the HyperTerminal program window. The serial port settings must be 8-N-1 at 9600 baud.

When any of the DIP switches are switched back to the OFF position, the Serial Server will revert to the mode it was in before Console Mode.

Note:

The Serial Server can be put into Console mode using either of two methods:

1.Switching all the DIP switches to the ON position

2.With any DIP switch in the OFF position set the Server Properties Console Mode field to Console and Update/Save the configuration

Making Hardware Connections

The ESP901 has one serial port. The port can be configured as a Console Mode connection or as an RS-232, RS-422 or RS-485 interface to the Serial Server (if any of the DIP switches are in the OFF position) using the ESP Manager software, via Telnet, or using the Web Server.

The ESP902 has two serial ports. Port 1 operates the same as the ESP901 serial port. Port 2 on the ESP902 is an RS-232 only interface.

The RS-232 interfaces are configured as DTEs. The connectors for all ports are DB-9M.

Using the ESP Manager the Serial Server can be put into Console Mode, Default Mode or Upgrade Mode. The serial ports can be configured for RS-232,RS-422 or RS-485 operation. The server also can be put into Console Mode by placing all the DIP switches into the ON position.
