USER FUNCTIONS — To change the password as a user:

1.Select Change Password from the File menu. Change password dialog appears. See Fig. 15.

2.Enter the desired criteria.

Enter user name and new password. Retype the new pass- word in Confirm Password.

3.Click OK.

OEM FUNCTIONS — All units are delivered with default OEM privileges. The system administrator must set units to User access.

To access OEM privileges:

1.Select Change Password from the File menu. See Fig. 16.

2.Change password dialog appears.

3.Select the desired User name from the list.

4.Change user permissions as desired.

Table 4 — Privilege Options

PRIVILEGE	OPTIONS
User privileges	Assign privileges as OEM or User.
	They can also be assigned Admin-
	istrator privilege which provides the
	ability to change user privileges. If
	you are assigned as a User, you
	can not add other users or change
	the passwords of other users. Click
	update for these changes to take
	effect.
New	Add a new user by typing in their
	name and password. You must
	retype the password to confirm it.
Change password	Change the password of an exist-
	ing user by typing in their name
	and password. You must retype the
	password to confirm it.
Remove users	Removes the currently selected
	user.

Using Hop Tables — A Hop Table is a listing of fre- quencies in a given spectrum that are used for communication. Data is sent to each frequency in the table in a hopping pattern. Hop Tables provide improved security and the ability to avoid localized noise sources. There are 101 possible Hop Tables in your transceiver (this number may vary for international trans- ceiver models). These are subdivided into five completely in- dependent, non-overlapping Hop Table sets, each with no more than three consecutive frequencies. Each individual network can only utilize one Hop Table.

ENTERING HOP TABLE NUMBERS — Hop Table num- bers can only be entered or changed by using the Quick Con- figuration wizard.

Enter the desired identification numbers. See Assigning IDs section for acceptable parameters. Select a Hop Table (0 to 100). The Hop Table selected must be the same for all trans- ceivers in a Point-To-Point or a Network. This number speci- fies a table of predefined frequencies, which the transceiver will use for transmitting and receiving. If multiple separate net- works exist in the same area, each network should have a unique Hop Table number to avoid RF collisions. Depending on which network is selected in the previous screen, certain ID fields may be grayed and inaccessible.

If multiple isolated wireless networks are installed in the same area, it is recommended that hop tables 1-5 be used sequentually.

VALIDATING THE HOP TABLE — This command veri- fies the integrity of the Hop Table stored within the transceiver. The Hop Table in the transceiver is compared to the Hop Table with the same number in the Configuration Manager database. The Advanced Settings tab provides the selected Hop Table number and whether the Hop Table has passed validation and the first and last indices used for the Hop Table. Index values are set to meet the requirements of the country in which the transceiver is deployed for a minimum number of hop frequen- cies. These values can not be changed to avoid violating coun- try regulations. To validate the Hop Table, from the Commands menu, select Validate Hop Table.

SPECIFYING HOPPING PARAMETERS — You can cus- tomize Hop Table parameters by setting some features avail- able from the Advanced Settings tab.

Max No Data — (Adjustment of these settings is not recommended.)

Max No Data is the number of hop cycles that must pass during which no data was received and no data was available for transmission before a session can be declared down. It is used as the trigger to end a session. After a certain number of Frames No Data between both units, the master will terminate the current session/link.

Max Bad Hop — (Adjustment of these settings is not recommended.)

Max Bad Hop is the number of data frames with errors re- ceived before a link is considered bad. This is the trigger to stop the current link and wait for a random standoff period (approx. 0.5 to 3 seconds). This is due to the assumption that after 4 consecutive bad hops (system default but can be changed), the link has been lost — either due to interference or lost synchronization. By waiting a small amount of time before attempting to reestablish the link, the obstruction (i.e., noise source) may have moved somewhere else.
