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.
This procedure is service-affecting.
