ESP-4 MI Serial Hub Installer/User Guide
All other connection methods do not require the use of drivers.
The file-driven ESP-Install program may be used to install, modify and remove Windows drivers
for ESP Ethernet serial hubs without need for on-site technical personnel. See
ESP-Install Program
on page 58.
Management tools
You may configure and/or manage the ESP-4 MI serial hub using the following tools:
• Web interface - see Chapter 4, beginning on page 25
• Configuration utility - see Chapter 5, beginning on page 35
• Configuration files - see Chapter 6, beginning on page 45
• Unix system utilities espcfg and espdiag (Unix systems) - these utilities have limited support
for connection methods other than port redirection
• Socket Application Program Interface (API)
The web interface and the configuration utility offer the most comprehensive sets of
available operations.
Using the web interface, you may launch the ESP-View diagnostic utility that provides datascope,
loopback and status functions. See
ESP-View Diagnostic Utility on page 52. The configuration
utility also supports diagnostic features; see Displaying and Using Debug Features on page 43.
The ESP-4 MI hub supports attended and unattended configuration. With attended configuration,
you set values and request actions directly through the web interface or the configuration utility.
Unattended configuration uses a flat text file containing configuration commands. The commands
are processed as if they were requested using the web interface or the configuration utility. The
command file may be read by BootP/DHCP during initial ESP-4 MI hub configuration.
Downloading a command file may also be requested using the web interface and configuration
utility. See
Configuration Files on page 45 for more information.
The ESP serial hub provides a socket API for on-the-fly serial port operations. This API is an
extension of the raw TCP interface, which allows data to be read from or written to an ESP hub
serial port. Using socket calls, an application is able to alter port settings (such as baud rate) or read
current serial control signals (such as DTR). For details on the API specification, contact Avocent
Technical Support.
