11. Console Access

The ETH-100 typically requires configuration prior to communicating on an Ethernet network. This fundamental configuration is achieved via a text-based console interface, accessible over an RS232 serial channel and a telnet interface. The following are the factory-set values of the most important Ethernet parameters:

IP Address.........................

10.0.0.101

Subnet Mask .....................

255.255.255.0

Default Gateway................

10.0.0.2

If these parameters do not match with your network settings, they will need to be modified.

11.1 RS232

The console is accessible via an RS232 interface for direct connection to a computer’s serial (COM) port. This is performed by using the included DB9- RJ45 cable to connect the ETH-100’s MMI port to the computer’s serial port. This will typically be the initial configuration channel, as the telnet interface can only be accessed once the network parameters have already been established and the device is communicating on the Ethernet network.

11.1.1 Requirements

All that is needed is a computer with a standard serial (COM) port containing some sort of communications software (such as HyperTerminal, shipped with Microsoft Windows operating systems) and the included MMI cable (ICC part number #10425). Any communications software and PC will work, provided they support ASCII communications at 38.4kbaud.

11.1.2 Connection

The ETH-100 ships from the factory with a dust cover installed in the MMI port. To minimize contamination of the port’s electrical contacts, keep this dust cover in place whenever the MMI port is not in use.

Connect the RJ45 end of the MMI cable to the MMI port, and connect the other end to the computer’s serial port. Make sure that switch SW1 #1 is in the “OFF” position.

11.1.3 Application Configuration

As previously mentioned, any PC communication software and PC serial port can be used. The software configuration example given here will be for Windows HyperTerminal communicating via COM1.
