Required Connections for System Configuration

Connecting a VT100 Terminal

Connecting a

Modem

The hub includes a menu-driven configuration program. The ASCII interface to this program is accessed by making a direct connection to the serial port on the Agent Module, or by a Telnet connection to the hub over the network.

This section describes how to access the menu-driven configuration program via:

❑Onsite connection

—A terminal or workstation connected to the serial port locally on the Agent Module.

❑Modem connection

—A workstation connected to the serial port of a remote via modems.

❑Telnet connection

—A workstation connected to a remote hub via a Telnet connection through the network.

It also describes how to access the embedded web agent over the network using any standard browser, or with network management software or other third-party mangement software.

Attach a VT100-compatible terminal, or a PC running a terminal emulation program, to the serial port on the Agent Module. Use the null-modem cable provided with this package, or a null modem connection that complies with the wiring assignments shown in the back of this guide.

When attaching to a PC, make the following terminal settings:

❑Terminal emulation type to VT100

❑Specify the port used by your PC, for example COM 1~4

❑Communications to 8 data bits, 1 stop bit, no parity, and 9600 bps (for initial configuration)

❑Flow control to none

Configure the Hub Site. Connect the Agent Module's DB9 serial port to the modem's serial port using standard cabling. For most modems, which use a 25-pin port, you will need to provide an RS232 cable with a 9-pin connector on one end and a 25-pin connection on the other end. You do not have to set the modem at the hub's site, because the hub will automatically configure it to auto-answer mode.

Configure the Remote Site. At the remote site, connect the PC's COM port (COM 1~4) to the modem's serial port. Set terminal emulation type to VT100, specify the port used by your PC (COM 1~4), and then set communications to 8 data bits, 1 stop bit, no parity, 9600 bps and no flow control.
