4. Configuration Options

Table 4-25. Communication Port Options (2 of 4)

Stop Bits

Possible Settings: 1, 2

Default Setting: 1

Determines the number of COM port stop bits.

1 – Provides one stop bit.

2 – Provides two stop bits.

Ignore Control Leads

Possible Settings: Disable, DTR

Default Setting: Disable

Specifies whether DTR is used.

Display Conditions – This option does not apply to the router.

Disable – Treats control leads as standard operation.

DTR – Ignores DTR. This may be necessary when connecting to some PAD devices.

Login Required

Possible Settings: Enable, Disable

Default Setting: Disable

Determines whether a user ID and password login are required to log on to the async terminal connected to the COM port.

Display Conditions – This option appears only when Port Use is set to Terminal.

Enable – Requires a login to access the menu-driven user interface.

Disable – Does not requires a login.

Port Access Level

Possible Settings: Level-1, Level-2, Level-3

Default Setting: Level-1

Specifies level of user access privilege for an async terminal connected to the COM port. If a login is required for the COM port, the effective access level is determined by the user’s access level. When a login is not required, the effective access level is determined by this option.

Display Conditions – This option appears only when Port Use is set to Terminal.

NOTE: The effective access level is always the lowest one assigned to either the port or the user. For example, if the Port Access Level assigned is Level-2, but the User Access Level is Level-3, then only Level-3 access is permitted for the port.

Level-1– Allows full access and control of the device, including monitoring, diagnostics, and configuration. The user can add, change, and display configuration options and perform device testing.

CAUTION: Before changing the communication port’s access level to Level-2 or Level-3, make sure that the Telnet Session Access Level is set to Level-1 and at least one Login ID is set to Level-1. Otherwise, access will be lost. If this occurs, you must reset the unit to the factory defaults and begin the configuration process again.

Level-2– User limited to display status, run tests, and view configuration option settings.

Level-3– User limited to display status and view configuration screens only.
