SECTION 3 OPERATION

VT100 USER INTERFACE

The TRACER may be accessed with a VT100 compatible terminal set to 9600 bits per second, 8 data bits, and no parity, connected to the RS-232 port on the back of the unit. Once a terminal is connected, pressing the “Ctrl” and “L” keys will redraw the current screen. If password access has been enabled, then press “Enter” or “Return” in order to see the “Enter Password:” message. TRACER is shipped with password protection disabled.

RS-232 INTERFACE

The TRACER has an RS-232 interface for system management via an attached VT100 terminal, personal computer, or modem. The RS-232 port is configured as a DCE with the following pin assignments:

CABLE CONNECTIONS

The cable connections required for various configurations are detailed in Appendix A of this manual.

PASSWORD

TRACER provides optional password protection of the terminal interface. If enabled, a password prompt is presented at power-up, reboot, or after thirty minutes of inactivity on the terminal. The default configuration is “No password.” Password protection is enabled via the configuration menu. The password is also set via the configuration menu.

If the password is forgotten, physical access to TRACER is required to access the terminal interface. The password may be bypassed by holding in the LPBK A button while the system is rebooted. This will bring up the terminal interface and allow the password to be changed or disabled via the configuration screen.

CAUTION

This procedure is service-affecting.
