TRACER 4108/4208 System Manual Section 5 User Interface Guide

>TRACER SYSTEM OPTIONS >ACTIVE T1 PORTS

Configures the dynamic receive sensitivity functionality on the TRACER 4108/4208. When 8XT1 ports are

active, the system receive sensitivity is -90 dBm (TRACER 4108) and -85 dBm (TRACER 4208). As the

delivered bandwidth is decreased, receive sensitivity improves as follows:

Both ends of the TRACER link must be set to the same number of active T1 ports. The TRACER 4108/4208

comes factory programmed with

ACTIVE T1 PORTS set to 8XT1.

>TRACER SYSTEM OPTIONS > MODEM CONTROL

Configures the modem control leads on the RS-232 port (terminal interface located on the rear panel of the

unit). Set

MODEM CONTROL to ENABLED when connecting the unit to a modem (using a null modem adapter).

Setting

MODEM CONTROL to DISABLED prevents the TRACER 4108/4208 from monitoring DCD and enables

data to be sent to the VT100 continuously.

MODEM CONTROL must be set to DISABLED when the VT100

terminal is in use. The TRACER 4108/4208 comes factory programmed with

MODEM CONTROL set to

DISABLED.

>TRACER SYSTEM OPTIONS > MODEM CONNECTION (LOGOUT)

Causes the TRACER 4108/4208 to de-assert Clear To Send (CTS) and DSR for a time greater than 20 msec.

This signals the modem to disconnect the analog connection. Hangup-On-DTR-Drop may need to be

explicitly enabled on some modems. If

PASSWORD PROTECTION is ENABLED, this menu also causes the unit to

close the current session and return to the TRACER System Status menu page and wait for password input.

>TRACER SYSTEM OPTIONS > PASSWORD ENABLE

Configures password protection for the VT100 terminal interface. Password protection for the

TRACER 4108/4208 requires password input from the TRACER 4108/4208 System Status menu page when

connecting to the unit. When configured for password protection, the TRACER 4108/4208 closes any

terminal session that remains inactive for more than 10 minutes. The TRACER 4108/4208 comes factory

programmed with

PASSWORD ENABLE set to DISABLED.

>TRACER SYSTEM OPTIONS > PASSWORD

Sets the password for password protection of the TRACER 4108/4208 VT100 terminal interface. Enter up to

8 alphanumeric characters. The system password is case sensitive.
