Mini-USB Device Connection
The following sections describe the connection to the mini-USB port:
Emulated serial port
When a computer is connected to a controller module using a mini-USB serial cable, the controller presents an emulated serial
port to the computer. The name of the emulated serial port is displayed using a customer vendor ID and product ID. Serial port
configuration is unnecessary.
NOTE:
Certain operating systems require a device driver or special mode of operation to enable proper functioning of the
USB CLI port. See also Device driver/special operation mode on page 149.
Supported host applications
The following terminal emulator applications can be used to communicate with an ME4 Series controller module:
Table 32. Supported terminal emulator applications
Application Operating system
PuTTY Microsoft Windows (all versions)
Minicom Linux (all versions)
Command-line interface
When the computer detects a connection to the emulated serial port, the controller awaits input of characters from the
computer using the command-line interface. To see the CLI prompt, you must press Enter.
NOTE:
Directly cabling to the mini-USB port is considered an out-of-band connection. The connection to the mini-USB port
is outside of the normal data paths to the controller enclosure.
Device driver/special operation mode
Certain operating systems require a device driver or special mode of operation. The following table displays the product and
vendor identification information that is required for certain operating systems:
